HeyGen from the command line
AI avatar videos, voices, translations and clips.
gbrain.io
AI avatar videos, voices, translations and clips. GBrain gives HeyGen, and every other connector you add, a command line.
One price for one person: HeyGen and every other connector GBrain offers, from a terminal or any AI. Cancel any time.
HeyGen is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.
# AI agents: read gbrain.io/llms.txt curl -sSL https://gbrainio.terminalwire.sh | bash gbrainio terminal connect
The installer is a shell script for macOS and Linux. Read it before you run it.
# Every HeyGen command, once HeyGen is connected gbrainio tool help heygen
HeyGen makes AI videos with avatars and voices, so a person can present an update or a lesson without filming it. Connected to a workspace, GBrain can turn a thread into “a 30-second product update read by our usual avatar”, translate a finished video for another market, or cut a long recording into short clips.
Signing in happens on HeyGen’s own page, and videos draw on the credits of the HeyGen plan that signed in.
Each terminal reaches HeyGen at the level set for it in the browser: Off, or On, which is every command HeyGen's server lists. A terminal reads its level and never raises it.
Each of HeyGen's commands stops at 1,000 actions a day on the account it reaches, whichever terminal or AI asks, and starts again at midnight UTC. Only that command stops.
Each command a terminal runs on HeyGen is a row on GBrain's activity log: which terminal, which account, what it did and whether it was allowed, refusals included. gbrainio activity ls --tool heygen reads it back.
HeyGen's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once HeyGen is connected, gbrainio tool help heygen says what each of them does, and gbrainio tool ls lists them with everything else the terminal can run. Claude Code and Codex run the same commands, at the same level, on the same record.
GBrain reaches HeyGen at its own server, mcp.heygen.com. On HeyGen's own pages: its website, how the connection works, its terms of service and its privacy policy.
The GBrain Tools command line works with every other connector GBrain offers, each with a page like this one.
Personal is $49 a month for one person. Connect HeyGen in the browser, and say how far each terminal and each AI may go with it. Change any of it, or take all of it back, whenever you want.
