Signify

Prove every word you publish is unmistakably yours.

Signify is the open-source writing platform that proves human authorship through keystroke verification. Publish with a shareable proof bundle that shows exactly how your story came to life—no AI, just you.

Why teams choose Signify

• Verified human authorship end-to-end with keystroke capture baked into every draft.
• Proof-ready publishing with a shareable bundle of drafts, replays, and session metadata in a single link.
• Public exploration with a library of verified essays and proof links.
• Live analytics that surface writing velocity, focus breaks, and correction patterns across your workspace.
• Built on modern Rails + React foundations so contributors can ship confidently and extend the platform quickly.

Platform highlights

Keystroke DNA

See the human fingerprint in every draft. Keystroke telemetry renders an immutable barcode of the writing session so reviewers can spot real authorship at a glance.

Proof bundles

Ship every story with an integrity packet. Each shareable link includes the full draft timeline, verified session metadata, and replay evidence to prove authenticity.

Immersive replays

Walk readers through every decision. Collaborators can scrub through the draft exactly as it unfolded—pauses, edits, corrections, and all.

Live analytics

Spot authenticity trends in real time. Aggregate keystroke evidence to understand writing velocity, focus breaks, and correction rhythms across your team.
