Judgment Layer

About

Judgment Layer drafts Gmail replies that sound like you — not like a generic AI.

It runs entirely on-device. Your email content, drafts, and learned writing style never leave your browser. No servers. No telemetry. No training on your data.

**How it works**
- Open a Gmail thread.
- Click the Judgment Layer button to generate a reply draft.
- The on-device model reads the thread, predicts the appropriate reply act (confirm, decline, ask, answer, etc.), and drafts in your voice.
- Edit the draft. The extension learns from your corrections — locally.

**Why it's different**
- **100% on-device.** WebAssembly + on-device model runtime. Your email stays on your machine.
- **Personal voice.** Style is learned from your own past replies, not a generic prompt template.
- **Welfare-framed corrections.** When you edit a draft, the model treats it as an anti-pattern to avoid — not training data to ship to a server.

**What it does not do**
- Does not send your email anywhere.
- Does not collect analytics.
- Does not require a login or account.
- Does not work outside Gmail.

**Requirements**
- Chrome 140 or later.
- First run downloads model weights (~few hundred MB) from Hugging Face. After that, fully offline.
