AI Mode

Describe what you need in plain English and get a password suggestion back — powered by Cloudflare Workers AI (Meta Llama). No prompt engineering needed: just type something like "16 chars, no symbols, for a banking app" and the model returns a tailored suggestion with a brief explanation.

Note: AI Mode is the only feature that sends data off-device. Your text prompt goes to Cloudflare Workers AI. Don't include real passwords or sensitive data in the prompt.
