Lumin from the command line
E-signature requests, templates and agreements.
gbrain.io
E-signature requests, templates and agreements. GBrain gives Lumin, and every other application you connect, a command line.
One price for one person: Lumin and every other application GBrain connects, from a terminal or any AI. Cancel any time.
Lumin 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 Lumin command, once Lumin is connected gbrainio tool help lumin
Lumin handles documents from draft to signature. Connected to a workspace, GBrain can answer “who still hasn’t signed the vendor agreement?”, send a reminder, or turn a Markdown draft into a PDF ready to sign.
Sending a request emails the recipients, so the recipient list shows before it goes out.
Each terminal reaches Lumin at the level set for it in the browser: Off, or On, which is every command Lumin's server lists. A terminal reads its level and never raises it.
Each of Lumin'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 Lumin 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 lumin reads it back.
Lumin's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once Lumin is connected, gbrainio tool help lumin 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 Lumin at its own server, mcp.luminpdf.com. On Lumin'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 application GBrain connects, each with a page like this one.
Personal is $49 a month for one person. Connect Lumin 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.
