1. Show HN: I created text expander/text blaze but for iOS app
URL: https://apps.apple.com/us/app/copynote-copy-what-matters/id1519660591
Author: newIOSDev
Description: Hello HN,
I use the text expander for my work all the time but It always bothered me that they don’t have mobile apps. I wanted to copy and paste notes/templates from the keyboard.
So, I created a side project, CopyNote.
I would appreciate any feedback on it.
I hope you’ll enjoy using the iOS app.
Cheers!

6. Show HN: Automatically tweet (X) the music you’re enjoying on Spotify
URL: https://bopping.to
Author: hipgrave
Description: Hey HN!
Excited to show a project called Bopping that makes it effortless to share the music your enjoying on X (Twitter).
Bopping connects to both your Spotify and X (Twitter) accounts, tracks your listening activity, and automatically tweets out your top 3 tracks every day (timeframe adjustable in settings).
When it knows an artists handle, it will tag that artist in the tweet, which has resulted in some nice artist/fan interactions. I often get artists retweeting or liking my tweets which feels very cool.
It’s been fun to see the tweets from the small group of people using it on my timeline. Would love for you to give it a try. Excited to hear feedback and see what tracks everyone’s vibing to.
You can see some other bops here: https://x.com/search?q=I%27m%20%40bopping_to&src=typed_query…
All bops are also added into a (rather eclectic) playlist: https://open.spotify.com/playlist/5bXlqMaUBEcwN8lP5CEZbN?si=…

16. Show HN: DocSend, but Made 10x Cheaper
URL: https://peony.ink/
Author: deqian
Description: Hey HN, founder of Peony here. Most founders use DocSend to share investment or sales docs and have to pay $65 to $300 a month to get the security and analytics features. It pains me to see startups getting ripped off when the availability of technologies such as Clickhouse makes real time analytics almost a trivial feature to implement in 2024.
We think it’s time to end the carnage and democratize the technology. We set ourselves a high bar: we don’t want to build another DocSend - we want it to be a far more superior product and also 10x cheaper.
After a couple of months of work, I’m proud to share with you Peony - a first preview into what we believe will be the future of file sharing. In addition to the analytics and security features you’d expect coming from DocSend, we built Peony to be flexible and adaptable across all your file sharing needs and give you the ability to deeply personalize your file share per recipient.
I’d love to hear what you think?
We are the Prometheus stealing fire from the guarded Olympian mountains. Help us win the rebellion.

It’s not curated so you’ll find a variety of things, some things are really creative and can be used for inspiration.

22. Show HN: I built an AI agent to monitor HN for interesting posts
URL: https://github.com/FabrkAI/home
Author: kmgrassi
Description: Hi HN!
I built an agent using Fabrk AI that periodically checks “top”, “show” and “ask” HN posts and sends me a summary email if it is AI related. Here is the repo with more details including a demo video: https://github.com/FabrkAI/home
The agent has several tools that allow it to get a list of posts, get one most, store the most recently reviewed article number and send an email. There’s even a little bonus at the end of the video about giving the agent more HN functionality ;).
You can configure the agent to query on any cadence and filter on any topic.
This agent is publically available. The link to fork the agent is in the GitHub repo.

23. Show HN: Self-hosted blog platform with AI workflow and full editing
Author: garagara
Description: Hello HackerNews,
I built a self-hosted boilerplate for blog/content creation because I think current AI writers have a big red flag: their limitations. My ideal AI writer should work for multiple projects and generate as many articles as needed.
How it works: First, you create a project and add topics. Each project represents a complete blog page, you can customize metadata, header, footer, CTA, and social media links.
I spend some time on how to generate content at best and I am happy with final result, here how it creates the content:
- Find relevant articles about your topic using advanced search algorithms
- Analyze and score these articles for quality (humanization, technical accuracy, and readability)
- Choose which articles to use right from the UI with an intuitive selection interface
- Pick from 6 different AI models (Claude, Gemini, OpenAI, XAI, Cohere, and Mistral) to create an article with references to those relevant articles—this way, we eliminate hallucination risk
- OpenAI scoring: After article creation, OpenAI scores the generated article based on quality metrics
- Iterate and publish: Create infinite versions of an article, pick the best one, and publish
- You can edit everything about your generated posts including content, meta tags, and URL slugs to perfect your SEO and content strategy
Looking forward to hear your feedback and opinions, cheers!

25. Show HN: Find Your Next Job Quickly Using This Chrome Extension – HN Hiring Pro
URL: https://chromewebstore.google.com/detail/hn-hiring-pro/mpfaljjblphnlloddaplgicpkinikjlp
Author: gj0
Description: Hi Everyone,
I created this extension to solve my own problem of applying to jobs via Hacker News. Searching through hundreds of comments manually and using browser’s built-in search is time-consuming and inefficient. This extension helps streamline the job search process on HN’s “Who’s Hiring?” threads by providing custom filtering, highlighting, and tracking capabilities.
Key problems it solves:
- Efficiently filter job posts by keywords, location, and requirements
- Highlight and track interesting opportunities
- Manage your application process with built-in status tracking
- Save time by hiding posts that don’t match your criteria
Here is a demo, https://www.youtube.com/watch?v=nwz88GyAAXY

31. Show HN: I built a service to localize Amazon affiliate links worldwide
Author: getproduct_dev
Description: I built getProduct, a service that helps content creators and affiliate marketers maximize their Amazon affiliate revenue by automatically localizing their links across 20+ Amazon marketplaces worldwide.
Problem: When you’re an Amazon affiliate, you typically get links that only work for one marketplace (e.g., amazon.com). If a visitor from Germany clicks your US Amazon link, they’ll not be redirected to the right marketplace.
Solution: getProduct creates smart links that automatically:
- Detect the visitor’s location
- Find the equivalent product in their local Amazon marketplace
- Redirect them to the correct regional store with your affiliate tag
Key features:
- Support for 20+ Amazon marketplaces worldwide
- Smart geolocation and automatic redirects
- Lightning-fast response times
- Intelligent caching to stay within API limits
- Simple API and dashboard
- Secure credential handling
How it works:
- You create a smart link through our UI
- Share that single link anywhere (blog, social media, email)
- When clicked, we detect location and handle the marketplace redirect
- You earn commissions from 20+ Amazon stores worldwide
Tech Stack:
- Ruby on Rails backend
- Tailwind CSS for UI
- Redis caching layer
- Stripe for payments
- Amazon Product Advertising API integration
Try it out: [getProduct.dev](https://getProduct.dev) Docs: [getProduct.dev/docs](https://getProduct.dev/docs)
I’d love to hear your feedback! What features would you find most useful? Any suggestions for improvement?
Note: I built it because I kept running into this problem with my own affiliate sites and couldn’t find a simple solution that “just worked” across all Amazon marketplaces.

33. Show HN: Redis-Store: A small wrapper to use Redis as a relational(ish) database
URL: https://github.com/desmat/redis-store
Author: desmat
Description: I built a small but opinionated wrapper to facilitate using Redis as a main database for my apps. Nothing too fancy: store your entities in JSON keys and it does the book-keeping to maintain lists and relationships. It’s been working great for me and so I figured I’d share with the community. Works out of the box in a Next/Typescript project with Redis on Vercel/Upstash or any instance via REST API.

34. Show HN: I built a Claude AI chat interface to bypass platform limits
URL: https://github.com/chihebnabil/claude-ui
Author: NabilChiheb
Description: I got frustrated with Claude’s official platform limitations - conversations disappearing, no customization options, and clunky file handling.
So I built my own interface over a weekend!
GitHub: https://github.com/chihebnabil/claude-ui
What it does:
- Saves all conversations locally (SQLite + Drizzle ORM)
- Lets you customize Claude’s personality per chat
- Handles file attachments properly + caching input tokens
- Dark/light mode
- No conversation limits
- Markdown & code syntax highlighting
Tech stack is pretty simple:
- Nuxt 3 for the frontend
- Anthropic’s SDK for Claude integration
- @nuxt/ui for components
- Local SQLite DB
Happy to answer any questions!

41. Show HN: I built a single-click lead collector to solve my fake email problem
URL: https://clikl.com
Author: William_relaise
Description: Hey HN,
As a developer who ventured into marketing, I hit a wall that many of us face: fake emails polluting our databases. After seeing 30% of my 2000-contact list being invalid or temporary addresses, I knew something had to change.
Traditional forms weren’t cutting it. Email verification was a band-aid solution. I wanted something more elegant - what if we could leverage Google Auth instead of asking users to fill out forms?
So I built a tool that does just that: one click to collect verified leads through Google authentication. No forms, no verification emails, no database cleaning. Just real, engaged contacts.
Technical challenges I faced:
- Building a multi-tenant architecture for board management
- Implementing real-time analytics without overloading the database
- Optimizing the Auth flow for minimal friction
- Handling rate limiting and quota management
Stack:
- Adonisjs
- Tailwind CSS
- PostgreSQL
- edgejs
- tsx
- TypeScript
- unpoly
First users are seeing:
- Open rates jumping from 25% to 45%
- Zero invalid emails
- 70% less form abandonment
- 5-second average signup time
Current limitations (being honest here):
- Google Auth only (more providers planned)
- English interface
Would love HN’s feedback on:
- Technical implementation choices
- Security considerations
- UX improvements
- Feature suggestions

I made ConvoCards because everyone has an interesting story to tell, but these don’t often come up in day to day conversations. I also enjoy using them for journaling and self reflection. I hope you enjoy playing and learn something new about someone close to you!

46. Show HN: MindPlexa – AI-powered visual project management platform
URL: https://www.mindplexa.com/home
Author: jaysth
Description: Hi HN! Solo founder here. I built MindPlexa to help professionals visualize and manage projects using AI.
Highlights:
- AI-powered project layout organization
- Infinite canvas workspaces
- Customizable node types
Tech stack:
- Next.js
- Supabase
- React Flow
- AI integration
Story: I created MindPlexa to turn any idea into a project and manage them visually. Just like file types we have node types (you can write notes, manage tasks, calendar / events, tables / data and drawings). They can be customized ( change color, add tags, attach files, resized etc), they can be dragged around and interconnected. The coolest part I guess is, you can enter a topic or the idea and AI will help you generate the layout (mindmap, workflow diagram, concept map, grid layout, hierarchical tree etc) with interconnected nodes. Let me give you an example: I want to write a book but I want AI’s help to generate the name of the chapters, instead if just text, in MindPlexa it will generate you chapters with a brief description for each and organize them visually. Now replace writing a book with any kind of project you want. Or you do it yourself from the scratch.
I’d love feedback
