Community Ninja
Hey everyone! 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…
Community Ninja launched on August 8, 2025 with 8 votes, #2,487 of 8,530 launches that month and more than 50% of that year's launches. The site was still online in September 2026, 1 year on.
What it does
Community Ninja is a browser-based AI agent that automates posting, lead extraction, and messaging across Facebook, Reddit, Telegram, and more—no APIs, no bans, just smart automation to grow your business without paid ads.
Community Ninja monitors Reddit everyday and finds relevant conversations about your product, market, competitors, customers, and pain points, so you can engage where it counts.

Linkeddit2025 · linkeddit.com · ▲618The tool actually hit Product Hunt #1 back in February. Since then I’ve added a bunch more on top of the original version. Now you just describe the intent or goal for the leads you want, and it searches based on keywords and a bunch of other signals to surface the best ones for you. I also added a Reddit-powered content writer. Basically, you pick a topic or category, and it pulls the top posts from Reddit, analyzes what made them go viral, and helps you write content using the same patterns. Reddit is super underrated for content. If something blows up there, it almost always spreads to…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
