What GBrain can do with 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.

  • Send a document or template for signature
  • Track signers, send reminders, or cancel a request
  • Download signed copies and certificates
  • Generate a document from a template

From the command line

GBrain gives Lumin a command line too. From a terminal, a script or Claude Code, gbrainio tool help lumin lists its commands once it is connected.
