The writing surface for people who care about authenticity, evidence, and craft. Write here. Prove it's yours.
A modern writing surface with the red pencil brought back. Markup that nests, replay that shows the work, exports that travel.
Process evidence for academic integrity. Teachers see how a paper was written. Students see the same record the teacher does.
Drop a .red.md file. It verifies offline, in your browser, no account needed.
Red Stet records the process of writing — every keystroke, every revision, every paste — and packages it into a verifiable file that travels with the document. Writers get a record of their own voice. Teachers get something to check a finished paper against.
The output is two things: a clean document, and a sealed chain of evidence for how that document came to be. Both stay with you.
Stet is the proofreader's mark — Latin for let it stand. When an editor scratched out a correction and circled "stet" in the margin, they were telling the typesetter: ignore my edit; keep the author's original. This is the writing the author meant; let it stand as theirs.
Red Stet records the writing so it can stand as yours, for the rest of your life.
Opt-in at sign-up. When you join Red Stet, you opt into the recording layer. Every doc you write thereafter builds a receipt. You can flip it off per-doc whenever you want; your account stays opted in for everything else.
What we record. Plain-text events inside the editor — keystrokes, paste actions, cursor moves, timestamps. Nothing rendered, nothing visual, nothing observed.
What we DON'T record. No microphone. No camera. No screenshots. No screen recording. No clipboard contents from other apps. No keystrokes outside this editor window. Same list, in this order, on every Red Stet surface that touches this.
At submission inside a classroom, the document and the receipt travel together. The teacher sees both. They're either consistent, or they're not.
Ever watched a dubbed film? The words don't match the mouth. You know instantly it's not the actor's voice in that moment. Red Stet does the same for writing — the document and the keystrokes either line up from start to finish, or they don't. — Why the recording works
