AI agents cite papers that don't exist. In medicine, that's a liability.

Same query. One ships into a clinical workflow. One shouldn't.

One retrieval layer. Two surfaces. Zero fabricated citations.

Call it as an API from your agent, or use our hosted workspace. Same guarantee either way.

  1. 01

    Query the literature

    Send a research question from your agent, or type one into our workspace. The retrieval layer does the reading.

  2. 02

    Every citation verified in real time

    Each paper is cross-checked against four databases. Anything unresolvable is dropped before it reaches your answer.

  3. 03

    Ship with real DOIs

    Every reference links to the source. Stream into your agent, or export to Zotero, RIS, or APA from the workspace.

Hosted workspace for researchers

A workspace that keeps every citation in place.

The reference implementation of our retrieval layer. Draft section by section from your verified library. Cite with a click. Export to Word with APA refs already in order.

  • Block-level editing, not one giant prompt
    The AI edits the paragraph you point at, not the whole document.
  • Citations pulled from your library
    Numbered references dropped inline as it writes. No copy-paste from Zotero.
  • Export to Word or Markdown
    Full APA reference list, formatted from real paper metadata.
