// the problem

Code changes were hard before.
Now, they feel impossible.

Your team moves fast with AI. But fast shouldn't mean risky. AI-generated code lacks verification. Manual reviews can't keep up. FixGuard makes sure every line earns its merge.

❌

Unverified AI Output

AI generates code, but who checks if it's actually correct?

Review Bottlenecks

PRs pile up. Security slips through. Technical debt grows.
