About this project
A Chrome extension that scores every message in your Gmail with TypeSafe's Jev model — category, priority, spam % and reply % (how much the message needs an answer from you). Inline in Gmail — badges appended to each row of your real thread list. Needs nothing but a Jev API key. The dashboard — the whole inbox in one sortable, filterable, exportable table. Needs a Gmail API OAuth client. Read-only: it never sends, deletes, labels or archives anything.
Quoted from the project's README. Read the full README.

Highlights
- Inline badges append category, priority, spam, and reply scores to each Gmail row.
- Dashboard adds search query control, max-message fetch, sorting, filtering, and CSV export.
- Spam combines deception, solicitation, domain, and notice signals with DMARC evidence.
- Custom categories are one line each, and editing them triggers automatic re-scoring.
Watch out
The Gmail overlay depends on obfuscated class names Google can change, and dashboard table renders 400 rows at a time for large inboxes. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
The overlay reads sender, subject, and preview from the page and needs only a Jev key. The dashboard needs a Google OAuth client with Gmail API access, so skip it if badges are enough.
Only sender name and address, subject, short preview, and Gmail tab. Message bodies are never fetched, and the extension never sends, deletes, labels, or archives anything.
Each message gets six narrow questions in one request, then code combines them with DMARC results and Gmail spam-folder state. Asking spam as one question scored a genuine billing notice at 86%.
About 2,000 tokens per email at input-token billing, roughly 9 cents per 1,000 emails. Rows classify once and cache, so scrolling back and re-syncs skip stored results.
No. The overlay reads the sender, subject, and preview line straight out of Gmail's page, and only that metadata plus the Gmail tab is sent to Jev. Message bodies are never fetched.
Yes. Each category is a line written as Name: what belongs in it, and that description is the rubric Jev scores against, which the README calls the biggest lever on classification quality.
Jev allows 1,200 requests per minute. Lower the parallel-request setting if you start seeing 429 errors, or raise it to classify faster.
