# Seer: Debug faster at every stage of development > Seer is the AI debugger that uses Sentry context to flag breaking changes, automatically root cause issues in production, and fix what you missed. **URL:** https://sentry.io/product/seer/ --- Seer is Sentry's debugging agent. It turns your telemetry into answers and gets you the fix, right where you're already working. ## Features ### New issue at 2am. PR is ready for review. When a new issue hits, Seer investigates automatically to find what broke and why. By the time you open your laptop, there's already a pull request waiting. ### Ask Seer anything. Not everything starts with a Sentry alert. Sometimes you just know something is… off. Describe what you're seeing in plain language. Seer pulls the relevant signals and answers the questions that don't have an obvious starting point or solution. ### Debug wherever you work. Seer doesn't just live in Sentry's UI. Send fixes to Claude, Copilot, or Cursor. Fix bugs from a Slack alert. Start an incident investigation in Slack where your whole team can see what's happening. ## Features - **Ask Seer Anything**: No context-gathering, no copy-pasting stack traces. Just ask Seer Agent what's wrong and get an answer from your actual production data. — [Learn more](https://sentry.io/product/seer/agent/) - **Errors come with fixes now.**: Seer Autofix reads the stack trace, traces the root cause through your codebase, and drafts a fix — before you've finished reading the alert. — [Learn more](https://sentry.io/product/seer/autofix/) - **Catch tomorrow's bugs in today's PR.**: Seer reviews your PRs against real production data — the errors, traces, and failure patterns Sentry has already seen from your app. If your change is going to cause problems, Seer tells you without spamming your PR. — [Learn more](https://sentry.io/product/seer/ai-code-review/) ## FAQ **How much does Seer cost?** Seer is available to all Sentry users on a paid plan (Team, Business, or Enterprise) at $40 per active contributor, per month.
