2. Show HN: Leftwrite the AI Co-Writer
Author: productmode
Description: Disclaimer: this AI doesn't write for you.
I've been blogging for about a year now and think writing is a great skill to have. I had 2 newsletters and tried Substack, Ghost, Posthaven and Beehiv. These are all great, but the hardest part about writing for me was a) developing a unique style and b) the brainstorming and editing. The brainstorming is fun, but the drafting can be hell. Anyway, I've used a few tools supposedly meant to help with writing, but none has been what I'm looking for beyond syntax and tone of voice.
I'm building LeftWrite, an Al co-writing assistant that adapts to your writing style and helps you write words that matter and will resonate with your audience. If this sounds interesting, or you've got any questions, hit the waitlist: leftwrite.xyz
Eager to get some feedback!

4. Show HN: IsItElon – Protect Your Loved Ones from Scammers on X
URL: https://regulaite.com/isitelon
Author: somefries
Description: I built this simple webpage to help prevent my aging mother from falling victim to scammers on X (formerly Twitter). She believed she was talking to Elon Musk, and despite numerous attempts to explain the situation, she wouldn't listen. Scammers posing as Elon convinced her that they were her boyfriend, and even tried to get her to send Bitcoin or buy gift cards.
This tool allows users to check if an X account really belongs to Elon Musk. It only recognizes the official @elonmusk handle, helping dispel any misconceptions about imposters using different accounts.
This little verifier finally convinced my mother. It might help protect your loved ones too—especially those who might not be as familiar with online scams. Feel free to use it if someone you care about is vulnerable to these kinds of tactics.

5. Show HN: Extract iMessage Attachments and Links into Organized Folders
URL: https://gist.github.com/rmtbb/c77deb7a697b032d374c57cf96aa98c8
Author: somefries
Description: I created a simple shell (zsh) script to help macOS users extract attachments (photos, videos, audio files) and URLs from their iMessages. The script pulls data directly from the Messages database (chat.db), organizes attachments into folders named after each contact or group conversation, and compiles all shared links into CSV files.
This tool can be useful for anyone looking to back up or organize files shared over iMessage without needing the entire conversation history. It also handles macOS's complex local storage structure for attachments.
No sign-ups or dependencies beyond macOS and SQLite. Just run the script, and it’ll create a neat export folder on your desktop. Would love feedback on any edge cases you encounter!

6. Show HN: CMD+C – Instant Grammar Correction Across All Apps for macOS
URL: https://cmd-c.app
Author: Hormold
Description: Hey HN!
Here is my simple native macOS app for correcting grammar — CMD+C.
I'm a non-native English speaker working in English-speaking teams, and I care about how my Slack messages and other communications come across. Frustrated with switching between grammar tools, apps that don't support some input boxes, and endless copy-pasting, I built CMD+C — a simple macOS app that corrects grammar on the fly in any app, with just a triple-click.
Features:
1) Triple-click "⌘+C" to correct any selected text instantly, no matter where you're typing.
2) Use your own API key (OpenAI, Anthropic) or access premium corrections with our plan.
3) View correction history with explanations from GPT why it was corrected and export JSON/CSV if needed.
How it works:
1) Intercept triple "⌘+C" shortcut in macOS
2) Process text with LLM (OpenAI, Anthropic) with custom prompt
3) Replace selected text with the corrected version and save it to better understand why and how it was corrected
CMD+C was built in 7 days, is free to use, and I plan to share the source code later this month.
I've never built anything before, so I'd love your feedback - let me know what you think! Hope someone finds it useful!

URL: https://www.textcapture.app/
Author: auden_pierce
Description: 1. Click capture text 2. Select an area on screen with text 3. Paste the text anywhere
Are there other solutions out there? Yes, the best one that I've found is Text Sniper, it $8 so I decided to learn SwiftUI and release Text Capture for $0.99. This one uses MacOS builtin Vision API under the hood so it should also improve with new macOS releases. Would love to hear your feedback!

10. Show HN: Tinder, but to Decide What to Eat
Author: kiru_io
Description: Hello HN,
My girlfriend and I waste too much energy to decide what to eat. Every day, we would text each other, "what do we eat tonight" messages, and go over options and many times spend too much time on deciding. I am an indie dev and created this app to solve my own problem: decide with my girlfriend what to eat for dinner.
Initially, I created a simple app, in which we listed all the recipes we ever prepared, and it would propose randomly three of them. We would then choose together one of them. This app[0] turned into a tinder-like app, which would propose every day a set of recipes to my girlfriend and me - we would swipe and go for the first match.
If have some time, give it a try and feedback is very appreciated!
Cheers, Kiru

32. Show HN: Open-Source Alternative for GitHub Copilot
URL: https://marketplace.visualstudio.com/items?itemName=flexpilot.flexpilot-vscode-extension
Author: suneelak
Description: After many months of effort, trying to build an open source alternative for GitHub Copilot, while still retaining the same native user experience it offers, we're happy to ship Flexpilot. (https://flexpilot.ai/)
You can try the VS Code extension here - https://marketplace.visualstudio.com/items?itemName=flexpilo...
Flexpilot requires VS Code 1.95 or higher.
While we loved GitHub copilot and the experience it offered, we wanted to use other LLM's to code effectively using VS Code and not just OpenAI. Also, there are lots of concerns around privacy and security at enterprises to send their codebases to the cloud. Several other coding assistants did not have the same native experience as GitHub Copilot and were only web views and we wanted to try and build something that will give us the best of both worlds - flexibility to choose LLM's (Cloud or on-prem) and native user experience, all within VS Code.
Flexpilot offers you the ability to choose from a variety of LLM providers such as OpenAI, Claude, Mistral, Gemini, AzureOpenAI, Groq or even other OpenAI compatible API providers. For instance, you can run Llama 3.2 or CodeLlama using Ollama on your local machine and inference it on VS Code using Flexpilot.
Not only in panel chat or inline chat, Flexpilot allows you to choose any LLM of choice in Panel, Inline, Code completions, quick chat, commit messages, Chat summaries etc.
Our repo is open source and you can find the details here - https://github.com/flexpilot-ai/vscode-extension
Happy to answer any questions on tech stack, comparisons with other coding assistants, etc.
Please try Flexpilot and let us know your thoughts!

34. Show HN: NotionPresso – React open source for Notion using Official API
URL: https://notionpresso.com/en
Author: rhdclrl
Description: Show HN: NotionPresso - Well-made React rendering library for Notion using Official API
Hi HN! I'm introducing NotionPresso, a React library that renders Notion pages using their official API. While there are several Notion-based blog solutions out there, most rely on HTML parsing, which can be unstable and limiting.
Key Technical Features:
- Built on Notion's official API for reliable rendering
- Infinitely customizable component architecture
- Full TypeScript support with comprehensive type definitions
What makes it different:
- Unlike existing solutions that parse HTML, we utilize Notion's official API for stable and extensible content rendering
- The component system is designed for unlimited customization - every aspect can be tailored to your needs
- The entire codebase is written in TypeScript with strict typing, providing excellent developer experience
We're actively working on Svelte support as well! Our goal is to provide the same powerful features and flexibility to the Svelte community, making NotionPresso a framework-agnostic solution.
The project is completely open source, and we've put significant effort into documentation and examples. You can create a fully functional blog with custom styling in minutes, hosted for free.
Docs: https://notionpresso.com GitHub: https://github.com/notionpresso/ Tutorial: https://notionpresso.com/tutorial
Looking forward to your feedback and contributions!

URL: https://kis.tools
Author: onuradsay
Description: Hey HN! Tired of hitting "Sign up for free" buttons only to discover the real limitations after creating an account? Or finding a "free" tool that adds watermarks to everything? Yeah, me too.
I'm building kis.tools, a curated directory of tools that: Work instantly - registration only when technically necessary, have genuine free functionality, keep interfaces clean and focused, process data locally when possible, keep promotional messages or ads minimal and unobtrusive
Think of it as a home for tools like Eric Meyer's Color Blender (running since 2003!) - tools that do one thing, do it well, and respect users enough to let them try before asking for anything in return.
Every tool is personally tested and described honestly, including limitations. No marketing fluff, just straight talk about what works and what doesn't.
Would love your feedback and tool suggestions, especially mobile apps - seems like every 'free' app nowadays sells its core functionality through in-app purchases.

39. Show HN: Blog Posts from Git Commits – A Tiny Tool for the Lazy Dev
URL: https://git2blog.streamlit.app/
Author: muc-martin
Description: I put together a small prototype that might help folks like me who struggle with keeping their website’s blog active just for SEO. It’s a basic tool: you enter your Git repo details (owner, name, branch), pick a date range, and it generates a short blog post from the commits in that period. The idea is to give small businesses and solo devs a way to keep their blog up-to-date with actual product updates without needing to write new content.
Right now, it’s still pretty minimal but I’d really appreciate any feedback, especially if you think this could be useful, or if you have ideas on how it could be improved. Should I keep developing this?

Description: I built an app that analyzes individual anatomical variations (limb lengths, joint alignments, mobility patterns) and matches them with biomechanically suitable exercises.
The matching algorithm considers:
- Valgus/varus alignment
- Limb-to-torso ratios
- Joint mobility ranges
- Anatomical leverages
It then cross-references these data points with a curated database of exercises to determine optimal movement patterns for each body type.
