How it works

From document to answer in three moves

  • Drop a file or link

    Upload a PDF, Word doc, or paste a public URL. RagBase indexes it in your browser workspace.

  • Ask in plain language

    Type the question you would ask a colleague — summaries, deadlines, clauses, next steps.

  • Answers point to the source

    Every response quotes the original text so you can verify before you act on it.

Templates

Start with a workspace built for your job

Each template includes tailored prompts, safe-use guidance, and a pre-named workspace — pick one and add your first document.

Template

Hospital AI Pilot Research

Research AI pilots with cited evidence

Built for hospital quality & operations work

Upload de-identified reports, public guidance, or proposal drafts. Every answer links to the exact passage — like an audit trail for what you read before you pitch a pilot.

  • Pilot research prompts for metrics, risks, and governance
  • Safe-use guidance for de-identified hospital data
  • Cited answers you can bring to a staff meeting

Do not upload passwords, medical records, or other highly sensitive information.
