14. Show HN: GodmodeHQ – Using AI agents to find public info on any company
Author: mafiaboi
Description: Hi hackers, Mert from GodmodeHQ here (https://godmodehq.com/)
We are building a prospecting platform for deep research so anyone can understand their prospects deeply and send better outreach instead of spray and praying a generic message.
Sales landscape is pretty crowded. Most solutions focus on sending the same email or Linkedin message to thousands of people.
This approach worked between 2010 to 2020 at best, however it became such a big habit that everyone started doing it. When you receive an outreach email that talks about the solution they offer without inferring how the solution could solve your problem, you automatically mark it as spam.
Now with AI, people started personalising. However this personalisation goes to the extent of where someone graduated from or if they shared a pic of eating ice cream on Instagram. This makes the outreach personal but still useless.
At GodmodeHQ, we implemented AI agents in form of columns in a spreadsheet. This resembles Perplexity integrated into a spreadsheet.
The agents recognise your website and embeds your ICP and context. So the only thing you need to do is ask:
“What are some of the pain points we can solve for the company?"
"Does the company have SOC Type 2 certification?"
"What are the recent feature launches they did?“
and more.
The agent automatically starts filling the information for you. Then you can use this information to really understand what problems you can solve for the customer.
Last step is reaching out to the customer using email and Linkedin. You can automate this part in GodmodeHQ as well however we do not deal with domain warmups or other similar practices that aim to let you send 10k emails on a day.
By design we encourage the users to go through the information agents have uncovered.
Our belief is that everyone sells. Whether it is your code or simple ecommerce products, you are a seller. You need to understand how you can sell.
Our vision is to turn non-salespeople into successful salespeople using the help of AI.
We hope you enjoy GodmodeHQ as much as we do.
I would love to hear your feedback.
Best,
Mert

15. Show HN: VRE Dataset generation for MultiTask vision models training from videos
URL: https://gitlab.com/meehai/video-representations-extractor
Author: meehai
Description: Been working on this tool for my PhD which involves training multi task vision models using various pre-trained models as inputs or pseudolabels in order to improve generalization. I work mostly on UAV datasets, but it should work okay on indoor scenes or self driving (at least Marigold and Mask2Former).
For example, this dataset was generated using this tool: https://huggingface.co/datasets/Meehai/dronescapes
I’m quite aggressively trying to “just get the nn.Module” from the public repos that other researchers put up in their overly convoluted frameworks. A simple forward(rgb_input: torch.Tensor) -> torch.Tensor is nice, having 100 imports from a generic framework that has versions incompatibilities with everything else is not.
PS: most mains are standalone runnable too, i.e.

18. Show HN: I Made a Chrome Extension to Prevent Developer Burnout
URL: https://www.deskbreak.app
Author: miguelfernandez
Description: I made a Chrome extension to help developers and other desk workers prevent burnout. As a frontend developer, I found myself neglecting my health during long coding sessions. This extension provides customizable break reminders and guided activities to help you stay productive and healthy.
If you’re curious about it, you can try it out here: https://chromewebstore.google.com/detail/deskbreak/fcmmkgomk…
Why I Made It:
After experiencing burnout myself, I realized that long hours of coding without proper breaks were affecting my productivity and well-being. This extension is my solution to help others avoid the same problem. It’s designed to be non-intrusive while ensuring regular, healthy breaks to help prevent burnout.
What You Can Do After Setup:
- Set your preferred break intervals according to your work schedule
- Receive customizable break reminders
- Try guided activities like stretches and eye exercises
- Track your progress over time
- Integrate breaks seamlessly with your workflow
Tech Stack:
- React for the UI
- JavaScript for core functionality
- Chrome Extension APIs for browser integration
- Tailwind CSS for styling
- Vite for the build process
Challenges I Faced:
- Balancing non-intrusiveness with effectiveness in a developer’s workflow
- Ensuring user privacy while storing preferences
- Optimizing performance within Chrome extension limitations
Feedback:
I’d love to hear your thoughts on how this could fit into your workflow. What additional features would make it more useful? Are there any issues you encounter while trying it out?

19. Show HN: Donobu – Mac App for Web Automation and Testing
Author: wewtyflakes
Description: Been working on a desktop app for Mac that lets you create web flows and rerun them (https://www.donobu.com/).
You can optionally use AI (BYOK: bring your own keys) to create flows for you and to do other interesting things, like making vision-based semantic assertions. Also, your data lives on your own filesystem, and we do not see any of it (further still, there is no phoning home at all). A nice benefit of this being a desktop app rather than a SAAS product, is that if you happen to be developing/iterating on a webpage locally, this has no problem hooking into it.
What this intends to be a good fit for:
- Testing web pages, especially locally.
- Exploring random webpages with a stated objective.
- Automating tedious flows. Rerunning a flow won’t get caught up on using a single selector (many websites randomize element IDs, for instance), there is smart failover using a prioritized list of selectors.
- Getting a quick draft of an end-to-end test in Javascript.
What this is a bad fit for:
- Mass web scraping (too slow).
- Adversarial websites.
What we are still working out:
- Click-and-drag operations.
- Websites that are primarily controlled from canvas.
- Smoothing out UI/UX (we are two backend engineers trying our best, and are handedly outgunned by real frontend engineers).
Fun things to try:
- Asking it to assert that a webpage has a certain theme.
- Asking it to run an accessibility report for a page (uses https://github.com/dequelabs/axe-core).
- Asking it to run a cookie report for a page.
The tech:
- Java 21 for the main business logic.
- Javalin 6 for the web framework (https://javalin.io/).
- Playwright for controlling the browser (https://playwright.dev/java/).
- Axe for running accessibility reports (https://github.com/dequelabs/axe-core).
Critical feedback is welcome. Thanks for trying it out!
Cheers, -Justin and Vaz

22. Show HN: FinetuneDB – AI fine-tuning platform to create custom LLMs
Author: felix089
Description: Hey HN! We’re building FinetuneDB (https://finetunedb.com/), an LLM fine-tuning platform. It enables teams to easily create and manage high-quality datasets, and streamlines the entire workflow from fine-tuning to serving and evaluating models with domain experts. You can check out our docs here: (https://docs.finetunedb.com/)
FinetuneDB exists because creating and managing high-quality datasets is a real bottleneck when fine-tuning LLMs. The quality of your data directly impacts the performance of your fine-tuned models, and existing tools didn’t offer an easy way for teams to build, organize, and iterate on their datasets. We’ve been working closely with our pilot customers, both AI startups and more traditional businesses like a large newspaper, which is fine-tuning models on their articles to automate content generation in their tone of voice.
The platform is built with an end-to-end workflow in mind, from dataset building, fine-tuning, serving, and evaluating outputs. The centerpiece is a version-controlled, no-code dataset manager where you can upload existing datasets in JSONL, use production data, or collaborate with domain experts to create high-quality datasets for custom use cases. We also offer evaluation workflows that allow non-technical contributors to annotate data, review model outputs, and refine responses (LLM-as-judge also available).
We offer:
- A free tier for developers and hobbyists who want to streamline dataset management.
- Business-tier with full feature access for teams, using per-seat pricing.
- A custom tier for model hosting, custom integrations, and self-hosting.
Most users still use OpenAI models, but if you’re working with open-source LLMs, we offer pay-as-you-go pricing for serverless inference for Llama and Mistral models with up to €100 in free credits to get started.
We’re in public beta right now, so any feedback—whether it’s about features, usability, or anything else—would be incredibly valuable.
If you’ve worked on fine-tuning models before or are curious about custom LLMs, we’d love to hear from you. Our goal is to make the fine-tuning process more accessible and help more companies leverage their data and domain experts to create custom LLMs.
Thanks for checking it out!

URL: https://quickdessert.recipes
Author: ailibrarian
Description: It’s not just your average recipe site – they’ve got an AI-powered feature that generates custom dessert recipes based on your preferences or available ingredients! If you’re short on time or ingredients, the site lets you tweak recipes on the fly. You can adjust ingredients to suit your pantry, dietary preferences, or time constraints, and the AI will instantly generate a new dessert idea for you. Super handy for those moments when you have a sweet tooth but not everything in your kitchen!
For example, I tried out a brownie recipe and swapped out sugar for honey – worked like a charm! The flexibility and ease make it really fun to experiment with desserts without spending hours searching for ideas or second-guessing ingredient swaps.

29. Show HN: Itineraries.io – I built a joint trip planner in between surgeries
Author: samaralihussain
Description: Hey HN,
For the last several weeks, I have just been sleeping, eating, operating and developing itineraries.io. Rinse and repeat.
I work as a surgeon in the UK. My main other passions are travel and programming. Recently, when I haven’t been stitching someone up, I’ve been working on my project.
Having always dreamed of exploring the world as a child, I struck a goldmine when I found a wife who shared the same love of adventure as me. We couldn’t afford to travel much when we first met at university. Over the last couple of years, since both entering the workforce, we have been able to live out some of our dreams. It has been wonderful. We now have a little one coming along and I can’t wait to adventure as a family.
I created itineraries.io because my wife and I usually rely on making Excel spreadsheets for our travels. These eventually become quite detailed. I thought a better user experience could be designed, and a community could grow from it centred around adventure.
Here are the main benefits I envision of using itineraires.io:
- Everything you need for your trip stored in one location (tickets, driving directions, travel documents, etc)
- Collaborative planning: plan your trip with your companions by sending a joining link via email
- Community: save your favourite itineraries made by others, clone them with a single click, and make them your own
I’d love to hear your thoughts and feedback :)

30. Show HN: Built a SaaS Idea Generator to Find Unique, Non-Saturated Startup Ideas
URL: https://maze.do/saas-ideas
Author: ericssonrd
Description: I built a tool that helps you generate unique SaaS and Startups ideas based on your specific skills, knowledge, interests, and desired keywords/topics.
Here’s how it works: You input your expertise, what you’re passionate about, and any specific areas you want to explore. You get tailored ideas as the generator analyzes your input and combines it with related market problems and requests to suggest relevant solutions.
Each idea comes with a description of the problem to solve, use case example and marketing angles to help you validate and refine the concept.
I built it because I was personally frustrated with the lack of tools for generating truly unique and viable SaaS ideas. Existing resources often felt generic and didn’t consider my strengths and interests.
Please give me your thoughts on things like idea quality, if you find generated ideas truly unique and potentially valuable, what additional features would be helpful for validating and developing these SaaS concepts, etc.
Try it out and let me know what you think: https://maze.do/saas-ideas

32. Show HN: Slash your LLM Inference Costs with Overnight Processing
URL: #
Author: Blue_Cosma
Description: Hey HN,
If you tried running open-source models like Llama 3.1 70B or 405B, you might have noticed that it gets very expensive. The reason looks obvious enough that you might have stopped even before trying it!
- GPUs are very expensive to buy or rent
- Running the most performing LLMs need 4, 8 or even 16 top of the line Nvidia GPUs
- And that won’t get you anywhere near the level of VRAM needed to batch enough to get a decent throughput and efficiency
Some have even questioned if open-source LLM providers are not doing some shenanigans to provide the prices they offer. VC funded bait-and-switch? Unclear quantization? Even the most well funded LLM inference startups, with the best inference optimization teams in the world have got into controversy about this.
At EXXA, we wanted to make affordable the best open-source LLMs in all their FP16 glory.
And I don’t know for others, but we’re a bootstrapped team of 3, so the subsidizing part isn’t an option :D
I won’t tell you we found the magical solution for all use cases… But we found one for batch overnight jobs to generate synthetic data or things like:
- Data pre-processing (e.g. contextual retrieval for RAG enhancement, knowledge graph)
- LLM-as-a-judge evaluation
Why overnight? Because it gives us time to:
- Get GPU for a high discount (30-70%) as they would otherwise sit idle in cloud providers data centers
- Heavily optimize inference for maximum throughput instead of minimum latency
Today, our batch inference API is live for Llama 3.1 8B & 70B FP16 with output under 24h.
We offer the lowest price per token in the market! 60% cheaper than fireworks, 40% cheaper than deepinfra. Without any hard rate limits and with prompt caching available.
Try it now at withexxa.com
—-------- If you have any questions: you can contact us at [email protected]
If you want to generate a large amount of tokens with custom LLM models, we can host them and offer the same price ranges as Llama 3.1 8B & 70B.
What do you think of our approach? Are you willing to wait for super cheap prices for AI inference?

Author: krisozy
Description: Hey everyone!
I’ve developed a few mobile apps and realized how time-consuming and challenging it is to create titles, subtitles, keywords, descriptions and localizations for a new app. To simplify this process, I created an easy-to-use toolkit that helps generate titles, descriptions, subtitles, and keywords just by entering a small description about your app.
Additionally, I added a few more advanced tools:
Keyword Ranking Tracker - Track and monitor your and competitors app’s keyword rankings
Keyword Research - Find the best keywords by identifying the perfect balance of search volume, ranking, and difficulty
AI App Listing Optimizer - Use the power of AI to optimize your app’s metadata in just a few clicks
To make this toolkit accessible to every developer and app publisher, I have set pricing well below that of the competitors.
Would love to get your feedback. Any ASO tools you’d like to see added?

40. Show HN: I made a free (open-source) extension, to use any LLM on Google sheet
URL: https://www.aisheeter.com/
Author: tuantruong
Description: Hello everyone,
This past Saturday, I decided to make purchase on Cursor after hearing how good it is with Composer function that allow to generate code on fly, especially on Claude Sonnet (not an affiliate of the products, just curious!).
To make the purchase worthwhile, I challenged myself to build a Google Sheets extension in just 24 hours that allows users to connect with any Language Model (LLM)—whether it’s ChatGPT, Claude, Groq, or Gemini.
The Idea The idea was simple: a formula like =Claude(prompt, model) that lets users integrate AI anywhere in their sheets. The most impressive part? 80% of the process was just tabbing and prompting AI, while only *20% was actual coding The Tech Stack Frontend: React with Next.js Backend: Node.js with Next.js API routes Database: Supabase AI Integration: OpenAI API, Anthropic API, Groq API, and Google AI API Development Assistance: Cursor and Claude Sonnet 3-5
The Journey Planning (2 hours): I started by using Claude Sonnet 3-5 to brainstorm and outline the project. It handled so much of the heavy lifting when it came to feature ideas and technical suggestions.
Frontend Development (8 hours):With Cursor, I was literally tabbing through suggestions, and it felt more like prompting AI to get the right code rather than writing it myself.
Backend Development (6 hours): The same pattern applied here: I spent most of the time tabbing through Cursor’s suggestions and tweaking AI prompts for the backend, which helped me set up secure API endpoints and efficient database schemas.
AI Integration (4 hours): This was the core part. I integrated multiple AI models to give users options. Claude helped refine the prompts and handle API responses with ease.
Testing and Debugging (3 hours): Cursor and Claude once again made it feel like I was navigating through the process rather than writing tests from scratch. Their combined tools flagged issues quickly, cutting debugging time in half.
Documentation and Deployment (1 hour): Drafted clear documentation with Claude’s help, and Cursor’s deployment features made production a breeze.
Key Features AI in Google Sheets: Use AI directly with simple formulas. Multiple AI Models: Support for ChatGPT, Claude, Groq, Gemini, and more.
- Cost Tracking: Automatic token calculation to track usage costs.
- Security: Encrypted API key storage for peace of mind.
Demo of the app : https://www.youtube.com/watch?v=HczW0F_tmvo
Challenges & Solutions The biggest challenge was integrating multiple AI models seamlessly. But with Claude Sonnet 3-5 guiding the architecture and Cursor suggesting solutions, the integration was mostly about tabbing and prompting. The architecture now easily accommodates different AI services.
The extension is completely free at. : https://workspace.google.com/marketplace/app/aisheeter_smart…
What’s Next I named the project AISheeter.com - Sheets Smarter not Harder
I’m releasing it for free and open-sourcing the code [here](https://github.com/Ai-Quill/ai-sheet-frontend.git).
This is just the start—let’s see where it goes from here! Website is at : https://www.aisheeter.com/
Takeaway What stood out the most throughout this project was how much AI could take over the coding process. It was 80% navigating through suggestions and refining prompts, and only 20% traditional coding. With the right tools and mindset, it feels like the boundaries of what’s possible in such a short time are expanding.
Excited time ahead with AI !

I built it just for fun and launched it a day after the o1 release. It’s not perfect yet but its still amazing to see how a detailed prompt can have such a difference on the quality of the LLM response!
Please let me know any feedback or suggestions! Thank you!

43. Show HN: I Built a Document Conversion API to Cut Costs
URL: https://doxswap.com
Author: deemonic
Description: Hey HN!
I built Doxswap because I was spending hundreds of pounds each month on document conversions. It was frustrating, so I created my own tool to handle unlimited conversions for a fixed monthly price. This is the service I wish I had—a reliable API with unlimited conversions for a fraction of the cost.
You also get a free API key with 50 conversions when you sign up. Would love your feedback! Check it out at doxswap.com.

44. Show HN: A better way to browse arXiv AI research papers
URL: https://thelatestinai.com
Author: fl0under
Description: Hey HN, I’ve built a site to help discover AI research papers by categorising them into research topics which can be explored.
Keeping up with the latest research is hard, particularly if you are interested in more niche research that doesn’t make the front page of HN or trend on twitter, so I built this so I can explore the topics I am interested in. There has been a bunch of tools based on arXiv shown on HN before, and of course well known ones like arxiv-sanity, but none that really worked in the topic/timeline based layout that I wanted (I found after starting mine that Semantic Scholar’s topic beta is closest!).
The papers are from arXiv categories most related to AI/ML and goes back to a few years worth of papers, currently updated once daily.
In the backend it uses embedding models to cluster keyphrases from each paper, that is then used to generate the topics. The generated names of the topics is not completely perfect yet, I have improvements to make but have been focused on building the frontend to get something out there!
Right now you can sign in and save papers - in the future I want to add in the ability to follow topics to get personalised updates, along with a bunch of other features.
I am interested to hear if anyone finds the site useful!

45. Show HN: Empower ChatGPT: Enhanced Doc Q&A and Academic Reading
URL: https://chromewebstore.google.com/detail/doc-insight/pfkgmepjhjjijjkbkoehbfioolmaecjc
Author: Shawn1991
Description: I’ve been using ChatGPT a ton for reading and analyzing documents—things like research papers, tech docs, code snippets. But I ran into a couple of hiccups:
1. Not enough functionality: ChatGPT’s built-in document reading features weren’t as smooth or user-friendly as I needed.
2. Costs: Other expensive services offered better features but wanted more money, even though they use the ChatGPT API behind the scenes. It felt kinda off to pay extra when I’m already a ChatGPT subscriber.
So, I created this Chrome extension Doc Insight that works directly in ChatGPT and offers following features:
Instant Document Preview: Upload and view documents right inside ChatGPT—no more juggling tabs or apps.
Auto-Generated Table of Contents: Easily navigate through long documents with a clickable TOC.
Real-Time Diagram Rendering: See diagrams and charts directly in your chat to simplify complex ideas.
Smart Prompts: Boost your understanding, generate and refine code in different programming languages, and test yourself with custom questions.
I’m continuously working on improving Doc Insight and plan to expand it to support other platforms like Claude, Gemini, and Poe.
Give it a whirl and let me know what you think! Your feedback would mean a lot and will help make it even better.

I built RepoGPT, an open-source AI tool that lets you interact with your GitHub repos using natural language.
Ask it things like:
How is auth implemented? List API endpoints. What are the key dependencies? RepoGPT aims to make navigating large codebases easier with AI.
Check it out: https://github.com/mbarinov/repogpt
You’ll need Node.js, pnpm, Docker (PostgreSQL), and an OpenAI API key. Full setup in the README.

54. Show HN: Zeli – HN reader with AI digests for non-native speakers
URL: https://zeli.app/en
Author: mazzystar
Description: I read Hacker News daily, but as a non-native English speaker, it often takes me a while to identify posts that interest me. So I created this tool—it uses an LLM to extract summaries and key highlights from articles, helping me quickly find the ones I want to read in depth.
If you’re a native English speaker, it can still be useful. Beyond just HN titles, it can give you a quick grasp of an article’s main points, allowing you to decide whether to click through.
Interestingly, for “Ask HN” posts, I’ve included a feature that selects the top 3 most insightful responses from the original thread. This lets you preview whether the comments section is worth exploring before you open the post.
Happy browsing!
