Crater — AI Risk Intelligence

About

Crater is a real-time risk intelligence layer for the AI tools you already use.
Every time you open ChatGPT, Claude, Copilot, Gemini, Perplexity, or any of 100+ AI tools, Crater scores the privacy risk — based on what the tool's policies actually allow, what trackers its site runs, and what data it can see about you. You get the score at a glance, in the side panel, before you type anything sensitive.

WHY CRATER
AI tools are the fastest-growing surface for data leakage. Most people don't read the policies. Most policies change without notice. Crater gives you a live read on what each AI tool is doing with your data — so you can decide what to share, and what to keep.

WHAT YOU GET
• Real-time privacy score (0–100) for every AI tool you visit
• Plain-language breakdown: what the tool stores, trains on, and shares
• Side-panel dashboard with risk history across sessions
• Built-in registry of 100+ AI tools, kept up to date with each release
• In-page alerts when a tool's behavior looks unusually risky

PRIVACY BY DESIGN
Crater itself collects zero data. Everything runs locally in your browser:
• No analytics, no telemetry, no tracking
• No URLs, prompts, or inputs leave your device
• No account needed — install and go
• Open permissions disclosure in our privacy policy

FREE FOREVER FOR INDIVIDUALS
Crater is free to use with no paywall, no login, no upsell. Teams can reach out at [email protected] for organization-wide rollouts.
