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.

Hey everyone! 👋 I built Community Ninja out of pure laziness. I was tired of manually promoting my product in groups, writing posts, messaging leads... it was draining. Ads were too expensive, and platforms don’t make it easy for solo builders to scale organically. So I hacked together something to do it for me — and accidentally made a tool that others started asking for. If you’ve ever felt buried under the repetitive grind of outreach and posting, I hope this saves you as much time as it’s saved me. Would love your thoughts, feedback, or even wild feature ideas — I built this for people like us. 🙌 ⚡ Key Features: - AI-generated keywords to find niche groups - Auto-post in Facebook, Reddit, Telegram, and X - Supports regular, promo, and buy/sell post formats (Any group, no admin required) - Extracts leads from comments & reactions - Auto-messages interested users Runs 100% in-browser — no APIs, no bans.

This is truely a lifesaver! The auto-messaging feature based on comments and reactions is such a smart way to focus outreach, ngl. Saves so much time compared to manually sifting through everything, right? How customizable are the message templates for different platforms?
