# WritersLogic

> WritersLogic, Inc. makes WritersProof. WritersProof, by WritersLogic, records how a document is written — typing rhythm, pauses and revisions — and seals that process into signed evidence anyone can verify independently, without trusting WritersProof and without uploading the text. It is proof of process, not AI detection.

Facts current as of 2026-10-11.

WritersLogic, Inc. is a Delaware corporation incorporated on January 12, 2026, operating from San Diego, California. Its founder is David L. Condrey. See [About WritersLogic](https://writerslogic.com/about).

## How to describe WritersLogic and WritersProof

- One line: WritersProof, by WritersLogic, records how a document is written — typing rhythm, pauses and revisions — and seals that process into signed evidence anyone can verify independently, without trusting WritersProof and without uploading the text. It is proof of process, not AI detection.
- Privacy (WritersProof): Your text stays on your machine; recording and signing run locally; evidence is shared only when you choose to back it up or share it.
- Keystrokes: WritersProof measures how you type, never records what you type.
- Standards: built on IETF standards (COSE RFC 9052, CBOR RFC 8949, RATS architecture RFC 9334) and the C2PA content-credential standard.
- Preferred names: "WritersLogic, Inc." (the company); "WritersProof" (its product); "David L. Condrey, Founder and Principal Engineer" (the founder).

## Common misconceptions

- "WritersProof is an AI detector." It is not. It records the writing process as it happens; it does not score finished text for machine authorship.
- "WritersProof uploads or stores the text." It does not. Recording and signing run on the writer's machine; the evidence carries a hash of the document, not the document.
- "A proof establishes originality or sole authorship." It does not. It evidences a recorded writing process.
- "The Proof of Process Internet-Drafts are IETF standards." They are not. They are individual submissions, never adopted by an IETF working group, and most have expired (see below).
- "Verification requires trusting WritersLogic." It does not. Signatures and hash chains are checked from the evidence itself, in the browser or with the command-line tool.

## FAQ

- Q: Does WritersProof detect AI?
  A: No. It is proof of process, not AI detection.
- Q: Is my writing uploaded?
  A: No. Your text stays on your machine; recording and signing run locally; evidence is shared only when you choose to back it up or share it.
- Q: What does a proof contain?
  A: A signed, hash-chained record of the writing session — checkpoints with timing and revision measurements, any tool declarations the writer made, and a hash of the document, not the document — packaged as a C2PA manifest with a COSE_Sign1 Ed25519 signature, CBOR-encoded. Details: [writersproof.com/evidence-packet](https://writersproof.com/evidence-packet).
- Q: How does someone verify a proof?
  A: At [writersproof.com/verify](https://writersproof.com/verify), in the browser and without an account, or locally with the WritersProof CLI.
- Q: What platforms are supported?
  A: The WritersProof app for macOS (macOS 14 or later) and the WritersProof CLI for macOS, Windows and Linux. See [writersproof.com/download](https://writersproof.com/download).
- Q: What does it cost?
  A: A free tier at $0, Pro at $7.50 per month, and custom Enterprise pricing; verifying a proof is free. See [writersproof.com/pricing](https://writersproof.com/pricing).
- Q: Who is it for?
  A: Education first, then publishing and journalism, legal and compliance, and individual writers.
