Hey HN! I’m excited to share Community Ninja, a tool I built to make finding and engaging with online communities way easier. If you’ve ever struggled to keep up with communities on Reddit, Facebook, or X to promote a project or connect with users, this might be for you.

Here’s what it does:

Community Discovery: Scans Reddit, Facebook, and X using agents to find active groups talking about your niche or product. No more manual hunting.

Smart Engagement: AI analyzes conversations and suggests posts or replies that fit the group’s vibe, so you’re not just spamming links.

Multi-Platform Posting: Write a post once, and the AI tweaks it for each platform’s style, letting you share to multiple groups in one go.

I started this project after burning hours trying to promote my tennis app across Facebook groups. It was a mess—too many communities, too little time. Community Ninja now pulls in hundreds of users a week for me with way less effort.

I’d love to hear your thoughts! What’s your biggest pain point with community engagement? Any features you’d want to see? Let me know what you think or if you run into any bugs.

I got a crazy idea:

- there's a prize pool holding $10000 - anyone who put $0.1 into it will win the full prize, if nobody else participate within 5 min

All logic in an open-source smart contract.

What will happen?

It won't make any money but might gain a lot of traffic, worth building?

The extension gives a red dot notification when a a new deal is posted that you haven’t already seen. Also a quick way of viewing deals without booting up the entire website.

InkTodos is a calm, distraction free todo list optimised for e-ink readers like Kindle and Kobo. There are no login walls, no cloud sync, no fancy features. Just a simple checklist that you can keep open on your e-reader while you focus on what matters - your work, not a fancy todo-list app.
