Apps

Tools that stay in your tab.

Each app includes a clear promise, feature guide, and step-by-step walkthrough — then the working tool. No accounts. No uploads for processing.

Private peer-to-peer video.

Small-group video with screen share and chat. Streams travel browser to browser — not through our servers.

Send files browser to browser.

Encrypted transfers with no upload queue and no size quota — just a short code both sides can verify.

Chain local tools into one run.

Compose PDF, image, and text steps into a private pipeline. Export the recipe and reuse it anytime.

Sign and verify PDFs locally.

Draw or upload a signature, place marks on any page, and verify an on-device attestation — the PDF never leaves your machine.

Diagram and brainstorm together.

Infinite canvas with templates and live peer sync. Boards move between browsers — not into a cloud vault.

Score on-page structure locally.

Paste HTML, upload a saved page, or fetch a URL. Checks run in your tab with exportable reports.
