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.
