I found the exact thing every faceless YouTube "guru" is secretly using and charging you $5000 to set up. It's called AgentTube. It's free. It's open source. And it runs a full YouTube channel by itself. The setup is four lines in your terminal and one free Gemini key. After that it becomes a factory. It researches what's trending right now, writes the script, builds the thumbnail, optimizes every tag for search, generates the narration, assembles a real video file, and uploads it on a schedule you set. Then it does the thing no course ever teaches you. It waits 24 hours, pulls the real numbers off YouTube, and figures out why a video did well or died. Then it feeds that lesson into the next batch so tomorrow's video is smarter than today's. 99.9% of tools today stop at "make video." This one learns from every upload like a channel manager who never takes a day off.
