2. Show HN: Aux Machina – AI photo generator without complex prompting
URL: https://www.auxmachina.com
Author: jameswan
Description: Hey HN,
We’ve been on a wild journey building Aux Machina, and think it’s fun to share a bit of the ride with you. It all starts with a “what if.” What if we make AI-powered visuals without needing a PhD in prompting? Sounds straightforward, right? Turns out, it’s more like a series of sleepless nights and way more Python than we bargain for .
Picture this: We met at Harrison.ai in 2019, knee-deep in CNNs in a pre-ChatGPT world. We were building healthcare AI that saves lives — serious stuff. But between all the daily stand-ups and coffee refills , we realised, “Hey, we actually like working together!” (Shocking, I know.) Naturally, after life-saving AI, we took on the next obvious challenge … helping people create pretty pictures with way less hassle . Same level of world-changing impact, right?
So, with a “let’s make this happen” attitude, we got to work. We’re a small, execution-focused team that just wanted to make creating custom visuals way easier for small businesses, marketers, and creators who don’t want to deal with complicated AI prompts just to get something halfway decent. “How hard could it be?” we thought. Spoiler: it’s harder than we thought. We went with a Python backend and a TypeScript/React front end, nothing too fancy, but it gets the job done (mostly without crashing) . Although, we had one glorious moment where everything went down in flames for a time … because we didn’t update the .env file. Yup, just one tiny oversight that took hours to discover - like finding a needle in a haystack, if the haystack was also on fire. Fun times.
On the model side, we fine-tuned a latent diffusion model and added some low-rank adaptations to handle the image generation process. The best way to describe it? You feed in your ideas, and the model refines them through layers of noise reduction and reconstruction, bringing something (hopefully) that doesn’t look like abstract art . Sometimes it’s spot on, sometimes… not so much. But hey, we’ve all had our Picasso moments.
Modularity is a big deal for us. We don’t want to build one of those all-in-one, Swiss Army knife disasters that no one touches because it’s too overwhelming — and racks up tech debt faster than you can say ‘refactor’ . I’ll never forget the day we almost accidentally wipe out half the codebase because of a misplaced function. David, our solutions architect, still talks about it like a near-death experience. So yeah, we break things down into modular components. The result? We iterate quickly and improve individual features without breaking everything else — or turning the codebase into a spaghetti monster . We also can’t resist adding some large language model (LLM) magic for tasks like interpreting user inputs or the visual vocabulary tied to reference images. The LLM makes sure what you type turns into something that’s, well, pretty close to what you’re imagining. Most of the time, anyway . There were a few days when the output was stranger than a cat riding a Roomba.
A few things we’ve learned on the way:
- Building AI tools is like trying to herd cats — except the cats are on fire, and you’re trying not to get burned .
- React is great for making things slick and modular, but if you’re not careful, it’ll eat your lunch and your weekend.
- Latent diffusion models are super cool, but they need a lot of fine-tuning unless you want everything to look like Picasso had a rough day .
We’re super excited to see how people use Aux Machina as we head into the go-to-market phase . We were all sizzle and no steak, but now we’re as ready as a bride’s nightie on the big day. We’d love your thoughts (or even better, your brutally honest feedback).

6. Show HN: AI Code Reviews with deep code understanding
URL: https://callstack.ai/pr-reviewer
Author: inferense
Description: hey HN!
There’s lots of AI Code Review tools by now. Our experience with these tools has been quite poor so far so we decided to tackle this space differently.
We started building Callstack as a deep code understanding engine (you can check out the UI here: https://graph.callstack.ai) to understand complex codebases to a granular structural level. The premise for this effort is to serve an LLM with a deterministic context retrieval over a complex codebases which impacts the performance by a large margin.
With few experiments this enabled us to perform really well over simple tasks so we have shipped code reviews, talked to users and today it runs in production at companies of all sizes.
Today we are launching self-service for the Code Reviewer. It’s completely free for individual use and open-source repos. It’s also fully private, it runs as a Github / Gitlab action (the only 3rd party API request is to Anthropic) and supports 9 major languages.
You can try it out in less than 3 minutes with no credit card required, just install it on your Github / Gitlab repo.
Would love to know your feedback!

7. Show HN: Hasura PromptQL: A new way of talking to your data
URL: #
Author: tango12
Description: After many months of hard work, trying to understand the challenges and issues around AI and data, we’re excited to be able to share PromptQL (https://promptql.hasura.io), a new tool to build assistants to talk to your data.
Try it by building a GitHub issues assistant: https://promptql.hasura.io/docs/example-github
You may know Hasura as “the GraphQL on Postgres” tool, but the product has been significantly generalized since those early days, and last year, we launched Hasura DDN (https://hasura.io/blog/launching-hasura-ddn), the third major iteration of our data API product. Briefly, DDN was a major step forward in terms of the expressivity of Hasura - where Hasura v2 supported a few different major relational database vendors, DDN was built on the premise that we should be able to fetch any data, in any format, from anywhere, and help you bring it into a unified graph.
This metadata driven approach to building APIs is a great fit for the current needs of LLMs, and enables AI application developers to build quickly. Good AI needs great data, and data which can be queried in a standardized way - which is exactly what Hasura enables for humans (using GraphQL or REST), and now it can enable it for LLMs too.
The problem we see: Our most important realization was that good AI architecture flows from good data architecture, so we wanted to give our users the tools to build their data architecture without boundaries, bringing in any data sources, restructuring for efficient and purpose-built data access. Want to store data in some other place? No problem. Need to bring in a custom vector database with a specialized search mechanism? A fine-tuned LLM? We can support that too.
We also realized that existing AIs perform surprisingly poorly on real problems. Because of this, users simply don’t trust their assistant’s solutions. An AI might give a poor answer, or no answer at all, and requires a lot of human intervention and iterations to get to the right answer. This has led to the adoption of architectures like RAG, and purpose-built, one-size-fits-none tools.
Our solution: Hasura takes a different approach to others: our solution jumps off from two major observations:
- As others have realized, assistants do better when asked to write programs to solve problems, instead of reasoning through problems directly.
- In order to move data out of the LLM’s context and reduce the risk of hallucination, we can give the LLM an external memory in the form of stored artifacts.
PromptQL is a tool and runtime for LLMs which directly implements these ideas, by building a programmable API on top of the graph you already built with Hasura.
In addition, we’ve put together the Agentic Data Access benchmark (https://github.com/hasura/agentic-data-access-benchmark) to illustrate the problem, and to help compare solutions.
Happy to answer any questions about choice of tech stack, challenges, possible applications, comparisons with other approaches, etc.
Please try it out and let us know what you think!

URL: https://www.warpserverless.com/
Author: Huzza
Description: Hey HN, I decided to package up a tool I use ubiquitously when working with AWS.
Its a launcher similar to Spotlight, Alfred and Raycast. However its designed specifically for navigating to AWS resources.
If you work semi frequently with AWS it can be a real pain just navigating around the console. The idea of Warp is to reduce that amount of time as much possible.
If any of these features catch your eye then feel free to check it out.
- Cross account searching
- Cross resource searching
- Service result caching.
Its currently up for a one time payment and I have no plans to make it anything other than that.

11. Show HN: Build a map of your TypeScript codebase with static analysis and LLM
URL: https://braucode.com
Author: yyjhao
Description: Hi HN! I have been tinkering with the idea of detecting features/concepts in a codebase and decided to build this tool to help make sense of big codebases. Feed it a GitHub repo (private ones too, if you log in), and it can show you a high level overview of the codebase, with pointers to various entry points and core logics, as well as weird concepts within the codebase. The tool only stores the necessary metatdata (e.g. symbol name and line number) but the actual code is not persisted.
It only works for typescript for now as I work on improving the other aspects of the tool. Would love to hear any feedbacks from the community!

17. Show HN: Shimmer – ADHD-adapted body doubling
URL: https://www.tella.tv/video/cm2xgdn2m000803l48ovf8b1c/view
Author: christalwang
Description: I’m Chris, one of the co-founders of Shimmer. In 2022, following my ADHD diagnosis, I launched Shimmer (https://shimmer.care), a 1:1 ADHD Coaching for adults (HN launch here: https://news.ycombinator.com/item?id=33468611 ). One problem we discovered while running 1:1 coaching is that people weren’t able to actually follow through (in real life) on the ideas they came up with during their weekly sessions with their coach.
There is a concept called body doubling that’s popular within the ADHD community—it’s basically getting things done in the presence of other people. The positive accountability is proven to work. However, our members told us they tried other body doubling solutions or attempted to organize it themselves in real life but none of the solutions stuck. So we reverse engineered productive moments our members described, paired with scientific backing of what motivates ADHD-ers, and designed an online body doubling experience for our coaching members that provides a safe but productive space for them to get things done between weekly sessions.
A few of the motivators we infused into the traditional body doubling experience were 1) newness/novelty — each session has a different guided experience in the break like breathwork or stretching, 2) urgency — there’s a large visible pomodoro timer on the top left that counts down from 25 min, 3) community — the shared space is ADHD-friendly, and has a mood check-in & sharing functionality built in so you don’t feel alone, 4) accountability — there’s a task list where each time you check something off, it notifies the group, and you can view others’ as well if they opt in. Here’s a video walking through the product experience: https://www.tella.tv/video/shimmer-body-doubling-demo-8b1c
Our body doubling was created and iterated alongside thousands of people with ADHD on our coaching platform over 9+ months of building & iterating with them. We’re excited to unveil this experience. If you have ADHD (or executive functioning challenges), we’d love for you to check out coaching & body doubling and give us critical feedback.
Shimmer’s pricing: $140/mo. for Essentials plan (15-min weekly sessions), $230/mo. for Standard plan (30-min weekly sessions), $345/mo. for Immersive plan (45-min weekly sessions); all plans start with an additional 25% off the first month, HSA/FSA-eligible. The reason why the price is so high is that this is not a self-guided app or SaaS tool. You’re matched with a real, credentialed coach (not AI) and since ADHD coaching is not reimbursed in the US, the price is hard for us to bring down because the largest cost component is the coach’s compensation.
*We know these prices are still expensive for many people with ADHD. Here are the actions we’re taking: (1) we offer needs-based scholarships and aim to have 5% of members on them at any time, (2) we often run fully sponsored scholarships with our partners—over 60 full ride scholarships and 100 group coaching spots have been disbursed alongside Asian Mental Health Project, Government of Canada, and more, and (3) we have aligned our coaching model alongside Health & Wellness Coaching, which is expected to be reimbursed in the next years. If there are ways we can further drive down the cost, please reach out to me directly at [email protected].

Author: eigenvalue
Description: I recently needed a blog for my recent Next.js app, and wanted something that would look really nice and that could be integrated into my existing Next.js app to keep deployment simple and to give me more control over how it’s hosted and configured.
My goal was to get something that looked very slick, using modern CSS styling and rich client-side effects that would look great on desktop and mobile, and most importantly, something that would be very easy and convenient for me to create new blog posts and edit existing posts.
So I had the idea of using GitHub as the CMS and just writing the posts using markdown with some extra metadata at the beginning, and then basically parsing that into html/css. It ended up working really well, so I decided to turn it into a standalone open-source project, which you can see here:

URL: https://openhands.daytona.io/
Author: nkko
Description: We’ve built what we believe is the missing piece in AI development: an agent-agnostic middleware infrastructure that lets AI coding assistants run in parallel sandboxed environments.
Key technical features:
- Dynamic workspace provisioning with parallel sandbox environments
- Connect to the workspace with VS Code
- Full system interaction capabilities (shell, Git, LSP)
- Resource-optimized cloud infrastructure
- Enterprise-grade security and access controls
Why we put together this proof-of-concept:
Current AI coding agents are limited by working in single files or environments. We have a vision to enable agents to:
- Spin up multiple sandboxes to test different solutions simultaneously
- Access full development environments, not just single files
- Run real-time tests
- Scale compute resources efficiently
Our implementation addresses the core issues outlined in our CEO’s recent analysis of AI coding infrastructure (https://go.daytona.io/ai-coding).
This is a proof of concept demonstrating how AI agents can work with proper infrastructure support. We’re looking for feedback from the HN community, especially:
- Developers building AI coding assistants
- Teams working on development environment tooling
- Anyone interested in AI agent infrastructure standards
The code is open source and we welcome contributions. Happy to answer any technical questions!

Author: sdotdev
Description: As a student who struggled to begin studying, I built Study League to make revision more rewarding and engaging.
Study League is a gamified study platform where users earn points based on study duration, not just exam outcomes. My custom algorithm, which takes into account the users study time to promote longer sessions and sessions with breaks, and the users team already to promote progress, scores each session, and users can immediately redeem points to “buy” players, creating an immediate sense of achievement. With these players, users form teams, compete in ‘study matches’ with friends, and join leagues to track and compare progress—transforming revision into a shared, motivational experience.
If you can, I would appreciate feedback as this is one of the biggest projects I have made.
Thank you.

Description: Hello Hackers!
This is my personal project I built over a couple weekends and it’s one of the largest!
TikTok Influencers Database. I scraped 400k (and growing) influencers, scraped their videos, scraped the audio subtitles of their videos, and analyzed with LLM what products they promote in the video.
Also, this database allows you to query however you like and find which influencers exactly talk about your product or your competitors products!
I also used LLMs to categorize the influencers and it has over 3,000 subcategories, so you can target the influencers matching your niche precisely!
Comment if you would like to try it out. I’m looking for some beta testers for feedback! Any idea or comment how I could improve this is appreciated!

While S3 is gaining a lot of attention, I wanted to share why we prioritized Python APIs.
On centralized servers, distributed and scaling data storage are relatively straightforward, but they become challenging on a local device like a laptop. Meanwhile most of the solusions are too complicated for an experiment or your intuition.
Python support leverages its popularity in scientific computing, AI, and data analysis, simplifying local data-intensive app development.
Python bindings offer an ORM-like experience, enabling developers to focus on features.
We also plan to add WebAssembly support in the future. What do you think? We’d love to hear your feedback.
Tonbo performs well; see our benchmark: https://github.com/tonbo-io/tonbo/pull/198
Why use Tonbo to store data on S3?
Tonbo will provides a unified storage solution on S3, enable SQLite and PostgreSQL to act as stateless query engines.
Stay tuned!

41. Show HN: tparagen -A tool to make Go test code parallel-ready in bulk
URL: https://github.com/sho-hata/tparagen
Author: sho-hata
Description: Hello HN,
I would like to introduce tparagen, a CLI tool for Go developers. With tparagen, you can easily insert the T.Parallel() method from the testing package into your test functions, helping you make the most of Go’s built-in parallel testing capabilities.
Key features of tparagen include:
- Automates T.Parallel() insertion in both main and sub-tests, making parallel testing effortless.
- Handles loop variable reassignment for Go versions earlier than 1.21.
- Skips insertion if t.Setenv() is called in the test function.
- Supports nolint comments for parallel tests.
tparagen is designed to save you time and remove the hassle of manually adding parallelization to each test, especially in large codebases.
Give it a try and speed up your test suite. Happy hacking!
