Introducing

Unlock your
next discovery.

Pascal is an AI-native browser for scientists — it reads papers with you, searches 90+ sources, and speaks in your ear while you work.

Free · early access · macOS & Windows

Now on macOS & Windows — free

A browser that already read the paper — so the conversation starts at page two.

Drop a PDF, open a preprint, or just browse. Pascal reads alongside you — annotating, citing, and searching 90+ sources in real time.

  • Read

    PDFs, preprints, any page

  • Search

    90+ sources, evidence-ranked

  • Speak

    voice agent, hands-free

  • Recall

    personal knowledge graph

The scientific browser

One browser for the whole scientific method.

Pascal reads, reasons, computes and cites — turning the open literature and the doctor's own tools into actionable, fully-traceable answers. Here's what's inside.

  • Evidence

    Reads the literature — and cites every line

    Ask in plain language. Pascal reads the papers, answers with inline citations you can click straight to the source, and refuses to make things up.

  • Toolbox

    2,400+ skills, calculators & connectors

    Clinical scores, medical calculators, rare-disease scales, PCDT/SUS protocols and MCP connectors — the doctor's tools, one keystroke away.

  • Autonomy

    Deep research that runs on its own

    Kick off a question and close the tab. Pascal keeps searching, reading and synthesizing — and it's all there when you come back.

  • Visualize

    Scientific viewers, built in

    3D proteins (AlphaFold), molecules, genomes, pathways and networks render right in the page — no plugins, no export dance.

  • Digital twin

    Model the patient over time

    Temporal twins that project risk and trajectory, match trials and surface drug-repurposing leads — grounded, never a black box.

  • Compute

    Run real analysis inline

    A sandbox runs actual Python next to your notes — stats, plots, quick models — with the result rendered as a living cell.

  • Voice

    Hands-free, in your ear

    Talk to Pascal while you work. It listens, reads the page with you, and answers out loud — dictation included.

  • Memory

    Your second brain

    Everything you read becomes a personal knowledge graph — searchable, linkable, and yours across every device.

  • Privacy

    Private by design

    Runs on your computer, local-first and air-gap capable. Built for sensitive data — you decide what ever leaves the building.

Your library stays yours

Local by default.
Cloud only when you say so.

Highlights, annotations and chat history live on your device. Sync is opt-in, end-to-end encrypted, and there’s a one-click panic button that wipes everything, including the keys.

Open the browser
your library deserves.

Voice agent. Deep search across 90+ sources. Knowledge graph. Sandboxed notebooks. All in one tab.
