Wolfram
Computed answers and curated data.
gbrain.io
Wolfram makes Wolfram|Alpha and the Wolfram Language. Connected to a workspace, GBrain can compute an answer rather than guess one, like “what was the population of Austin in 2010?” or a unit conversion in a spec.
It is free for limited use and needs no sign-in. The connection only reads.
GBrain gives Wolfram a command line too. From a terminal, a
script or Claude Code,
gbrainio tool help wolfram
lists its commands once it is connected.
It is public, so there is nothing to sign in to. Then add it to a workspace, and anyone on the team can ask about it in plain words.
