Scope and authority
About this site
This is the generated reading and checking surface for Icosa Canon. The validated Canon data and shared checker engine are authoritative; these pages do not add new rules or term meanings.
Private by construction
Pasted writing is checked in browser memory. The site has no account, database, upload, saved-document history, analytics, telemetry, or hosted validation API. Checking does not send the text to Icosa or another server.
Current format coverage
The browser checker accepts plain text, Markdown, and MDX. It does not claim native understanding of HTML, DOCX, PDF, or other rich container formats.
Version identity
Every generated artifact and browser result identifies the Canon data revision used to produce it. This build uses manifest format 1 and Canon revision:
