research that organizes itself

Run agents on your research,
no setup required.

SpaceDoc is free with your own Claude Code or Codex login. SpaceDoc AI adds a built-in agent with a monthly usage allowance — for researchers who have neither.

SpaceDoc AI
$20 / month
  • Built-in agent — nothing to install
  • Cell fill, convert, organize — and chat that edits your notes
  • Auto (Grok) by default — fast and generous
  • Pro picks any top Grok, OpenAI, or Anthropic model
  • Monthly allowance, hard cap — no surprise bills

The allowance resets monthly and stops hard at the cap — usage never bills past your plan. Cancel any time from the billing portal; your remaining allowance keeps working until the period ends.
