Momentic Mo is generally available: an AI QA engineer that tests your app
The point
Momentic says Mo, its AI QA engineer, is now generally available. Mo tests apps end to end from a prompt, and a separate agent reproduces each bug before Mo reports it.
Why it matters
For builders, verification can run inside the coding agent loop, not as separate manual QA.
Key details
- Start from your coding agent, the app, a PR comment, or the qa CLI
- Site counters list 117,010 bugs caught and 77,813 tests created
- QA Bench: Mo found about 269 bugs in 20 areas, versus about 86 for the next best agent
