See what is missing before the email travels.

CHORDS marks the context it finds, shows what still needs attention, and prepares an editable footer for the user to review.

CHORDS Chrome extension side panel showing Caveat, Handling, Owner, Refresh, Definition, and Source checks for an illustrative email — CHORDS checking an illustrative sample draft. No real email content is shown.

What it does

CHORDS checks a Gmail compose or reply draft for six pieces of context: Caveat, Handling, Owner, Refresh/as-at, Definition, and Source.

Runs in Chrome

The extension reads the current Gmail draft only when the user asks it to check the draft. It does not send email contents to any other server.

Only uses local AI

The CHORDS check runs in the user's browser and does not rely on a third party. If Chrome's local model is unavailable, the extension says so and offers a blank footer.

No send blocking

The extension is a writing assistant. It does not send email, block sending, inspect attachment contents, or create audit logs.

User-controlled footer

The user can edit, copy, or insert a CHORDS footer into the draft. The extension does not invent metadata.
