Otto from the command line
Business travel search, booking, changes and cancellations.
gbrain.io
Business travel search, booking, changes and cancellations. GBrain gives Otto, and every other application you connect, a command line.
One price for one person: Otto and every other application GBrain connects, from a terminal or any AI. Cancel any time.
Otto 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 Otto command, once Otto is connected gbrainio tool help otto-travel
Otto is a travel assistant for business trips: it books flights, hotels and cars with loyalty numbers and preferences applied, and rebooks when plans change. Connected to a workspace, GBrain can answer “what time does my flight to Denver leave, and which hotel am I in?” or find options for next week’s trip.
Booking and cancelling spend money, so those are worth a person’s yes before they happen.
Each terminal reaches Otto at the level set for it in the browser: Off, or On, which is every command Otto's server lists. A terminal reads its level and never raises it.
Each of Otto'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 Otto 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 otto-travel reads it back.
Otto's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once Otto is connected, gbrainio tool help otto-travel 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 Otto at its own server, api.ottotheagent.com. On Otto'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 Otto 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.
