Key features	AI-generated Playwright and API tests from real user sessions Automatic test healing in real time as the application changes Human engineer verification before any test is marked ready Generated tests run as standard Playwright code in the team's own repo No per-seat or per-run fees, priced only by workflows maintained	Agents that play the build automatically Bug and glitch detection Performance issue identification No SDK integration required Broader coverage than manual test passes
Pros	Human verification adds a real reliability check beyond pure AI output Usage-based pricing avoids per-seat costs as a team scales A bootstrapped, revenue-generating company rather than a pre-revenue startup	Covers far more game states than a human team can visit No SDK integration needed to get started Well matched to a genuinely exhaustive testing problem
Cons	No self-serve trial or published pricing; every deal starts with a demo Only a LinkedIn company presence was found, no other public social account Relies on Playwright specifically, so teams on a different test framework aren't served	Pricing is not published and the pricing page 404s Finds traversal and performance faults, not design problems No automation can judge whether a game is fun
Company	Checksum, founded 2022	modl.ai
