# Lear > Lear is an AI engineer that stays on call inside a team's own infrastructure. When something breaks, it checks the signals and recent changes, proposes a recovery plan, waits for a person to approve it, acts only within the permissions it was granted, and verifies the system recovered. It is made by Drufiy AI Private Limited. Key facts: - Lear runs in the customer's environment (their cluster or VM). Credentials stay in the customer's secret store and are used in place; nothing routes back to Drufiy. - Every response follows six states in the same order: Observe, Diagnose, Plan, Approve, Act, Verify. - Lear starts read-only. Any change waits for a person to approve the exact plan. It ships in the "ask" permission mode, and every action is appended to an audit trail. - Pricing: the read-only trial is free. After that, Lear bills 15 to 20% of the savings it measures in the customer's environment. If Lear saves nothing, it costs nothing. - 13 connector implementations today: AWS, Kubernetes, GitHub Actions, GitLab, Google Cloud, Azure, Terraform, Datadog, Grafana, PagerDuty, Vercel, Snyk, Gitleaks. - Lear is pre-launch. Incidents on the site are labeled examples, not customer deployments. ## Pages - [How Lear works](https://lear.drufiy.com/#loop): the six-state loop, walked through one example incident (checkout returning 502s after a deploy cut a connection pool from 20 to 2) - [Savings calculator](https://lear.drufiy.com/savings): what incidents cost a team in engineer time, with every assumption editable and every source shown - [Pricing](https://lear.drufiy.com/#pricing): a share of measured savings, with a free read-only trial - [Trust model](https://lear.drufiy.com/trust): where Lear runs, the five guarantees (credentials in place, ask by default, append-only audit trail, dry runs, a circuit breaker) and what is deliberately left to people - [Download](https://lear.drufiy.com/download): the desktop app for macOS, Windows and Linux, plus `npx @drufiy/lear`, Docker and Helm - [Contact](https://lear.drufiy.com/contact): book thirty minutes with a founder ## Optional - [Full text for language models](https://lear.drufiy.com/llms-full.txt): everything above in more detail - [Privacy policy](https://lear.drufiy.com/privacy)
