Private process certificate
A private certificate is created from author-submitted process evidence. The author approves what becomes public. Readers see a proof link that explains the process without exposing private drafts.
Comparatus
Process proof for AI-assisted writing.
AI detectors can estimate whether final text looks AI-assisted. Comparatus documents how the piece was made: outline, source notes, draft evolution, and final text fingerprints.
Why now
Percentages do not explain the process.
Substack's rollout of AI detectors and "How I make this" statement are a clear signal: readers and platforms want more context around AI-assisted writing.
AI detectors can help estimate whether final text appears AI-assisted. The limitation is that a percentage does not show what the author actually did, reviewed, sourced, or changed.
Comparatus is the missing process layer: AI detectors give a percentage; Comparatus shows the author's process evidence.
What Comparatus does
Author-approved proof link
Public evidence is limited to what the author chooses to release, with a clear reader-facing explanation of the writing process.
Text fingerprints and hashes
Comparatus records text fingerprints/hashes for source and final text so process evidence can be checked without publishing private drafts.
What it does not do
Process proof is not detection.
- Not an AI detector.
- Not a plagiarism checker.
- Not a quality score.
