Agent Reach is a free command line tool that gives an AI agent eyes on the whole internet. One install and the agent can read and search Twitter, Reddit, YouTube, GitHub, Bilibili, and Xiaohongshu, plus regular web pages and RSS.
It does this without paid platform APIs. It picks the right open tool for each platform, checks that the tool still works, and switches to a backup when a platform blocks the first route. Cookies stay on your own machine.
The verdict from the reviewer: FACT. He tested it and stamped it FACT, and the repo backs it up. The code is public, the licence is MIT, and it was updated today, Oct 24, with over 100,000 stars on GitHub.
Cost: free. There is no API bill and no subscription. The only possible cost in the docs is a proxy at about $1 a month, and only if you run it on a server that a platform blocks. A local computer does not need one.
For me, this fits wholesale lead digging, social listening, and competitor research. Those jobs live on Reddit, YouTube, and X, exactly the places a plain web search reads badly.
