Hookmeter Jev

Both. Typing triggers a millisecond local heuristic plus cached results instantly, then a debounced Jev call returns Score, Choice and Noul judgments rendered in Shadow DOM badges.

No. Rendering uses Shadow DOM isolation, input tracking uses mutation observers with IME alignment and debounce, and pinyin composition does not spam requests.

No for local use beyond a key. Run the FastAPI server for development or paste the single-file worker to Cloudflare, set the key as a secret, and point the extension at the edge endpoint.

No. Beyond curiosity gap and emotional arousal scores it classifies hook patterns and flags violation-style clickbait with an exemption for substantive technical claims, then suggests a short prescription.

Four closed questions in one call against jev-latest, and nothing generative comes back. Two Score rubrics on 1-5 ladders for curiosity_gap and emotional_arousal, a Choice that classifies the hook pattern as contrarian view, high-value result, urgent pain, story or plain statement, and a Noul that flags restriction-risk clickbait, with a built-in exemption for substantive technical claims so real technical posts are not killed.

Yes. Create an app under Cloudflare Workers and Pages, paste the whole of cloudflare_worker.js into the editor, add TYPESAFE_API_KEY under Settings, Variables and Secrets, and deploy. The extension is then pointed at the resulting /api/analyze endpoint, so the key stays off the extension and ordinary users install it without needing one.

MIT. For local work: pip install -r requirements.txt, cp .env.example .env with your TYPESAFE_API_KEY, then python server.py, which listens on http://127.0.0.1:8000 and also serves a standalone web tachometer sandbox. The extension itself is a plain Manifest V3 package in extension/, loaded unpacked from chrome://extensions with developer mode on.
