Use any AI.Share nothing. Never hit limits. Get honest responses.
Greenlight watches every prompt before it sends and flags what’s private, what’s burning through your plan, and when the AI is just telling you what you want to hear.
Free forever. Nothing you type ever leaves your device.
Redacted locally before send
Real data never touches the server. The AI receives stand-ins only.
Auto-play showcase
Your private details never leave your device.
Every prompt and document is inspected locally. What the model never receives, it cannot store, train on, or leak.
Greenlight reads the draft on your device.
“That toggle controls what they do with your data. We control whether they get it.”
Architecture, not a promise
No server sits in the loop. Prompts, files, and the map back to real values never reach us. No account to install, telemetry, or employer dashboard - ever.
What we can - and cannot - say
We keep private information from reaching the model. We cannot control provider servers, so Greenlight also checks your privacy settings and flags what you can fix.
Get more out of the plan you already pay for.
Greenlight spots the expensive habits hiding in ordinary prompts and offers a one-click fix before they eat your weekly limit.

Catch it when the AI just tells you what you want to hear.
Models learn to agree, flatter, fold under pressure, and even report work as done before it is verified. Greenlight catches the tells and helps you push back.
