OpenBook Review: evidence checks as you browse

OpenBook Review reads alongside you in your browser. As you write in clinical contexts (Gmail, web-based tools, and more) it surfaces relevant evidence from published clinical guidelines and shows you the citation, evidence level, and a link to the source. It flags and cites. It never edits your text or makes a clinical decision. You decide.

Free during early access, no card required.

Four things it does

Auto-flag as you write

Copy any clinical text (⌘C / Ctrl+C) — including inside Google Docs — and OpenBook reviews it against ~35 guideline units in real time. Contradictions are flagged in red with the sourced guideline; consistent claims in green.

Review pasted text

Paste a note, plan, or paragraph into the panel and click Review — same evidence base as the auto-flag, on-demand.

Ask a clinical question

Ask evidence in plain language. The extension rewrites your question into a proper search query, retrieves the top real papers from Europe PMC, and synthesises a 2–3 sentence grounded answer — every citation traceable to a real record.

Article fit

Reading an article and unsure if it addresses your question? Article fit returns a high / partial / low verdict plus verbatim quotes from the article that address your question, and offers a broader literature search when the article does not.

How it works

Private by design

Identifiers are removed on your device before any check. No tracking, no ads.

Cited, never invented

Every flag links to a real, verified source. No citation it can't trace.

Flag & cite only

It highlights and cites. It never edits your text or advises. You decide.

Please read before using

  • Synthetic / de-identified content only during early access. Do not use it on identifiable patient records.
  • Works in Gmail, Word Online, most web text boxes, and — via ⌘C / Ctrl+C — inside Google Docs.
  • It is a decision-support aid, not a medical device. No flag does not mean a statement is correct. It means nothing in the current evidence base bears on it — coverage is expanding weekly.

By installing you agree to the Terms and Privacy Policy.
