Judgment Layer

Draft email replies in your personal voice. On-device AI, fully private.

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.
