Sybill from the command line
Sales calls, deals and pipeline, from Sybill.
gbrain.io
Sales calls, deals and pipeline, from Sybill. GBrain gives Sybill, and every other application you connect, a command line.
One price for one person: Sybill and every other application GBrain connects, from a terminal or any AI. Cancel any time.
Sybill is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.

The installer is a shell script for macOS and Linux. Read it before you run it.
# Every Sybill command, once Sybill is connected gbrainio tool help sybill
Sybill is an AI sales assistant that records calls and joins them with emails and CRM data. Connected to a workspace, GBrain can answer “which deals are at risk this quarter, and why?” or prep someone for a meeting with the full history of the account.
The connection only reads.
Each terminal reaches Sybill at the level set for it in the browser: Off, or Read, which only reads, as Sybill describes its tools. A terminal reads its level and never raises it.
Each of Sybill'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 Sybill 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 sybill reads it back.
Sybill's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once Sybill is connected, gbrainio tool help sybill 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 Sybill at its own server, mcp.sybill.ai. On Sybill'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 Sybill 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.
