Navan
Company travel and expense spend.
gbrain.io
Navan handles business travel booking and expenses. Connected to a workspace, GBrain can answer “how much did the sales team spend on travel last quarter?”, find who is traveling next week, or check whether a hotel is within policy.
The connection only reads.
GBrain gives Navan a command line too. From a terminal, a
script or Claude Code,
gbrainio tool help navan
lists its commands once it is connected.
You sign in on Navan's own page. No key to copy. Then add it to a workspace, and anyone on the team can ask about it in plain words.
