Checksum AI

Checksum.ai leverages machine learning to transform real user sessions into comprehensive end-to-end (E2E) tests. It autonomously generates tests in Playwright or Cypress frameworks, automatically discovers both happy paths and edge cases, and self-heals test scripts in response to code changes. This enables faster, confidence-driven shipping of bug-free web applications, with minimal manual intervention. Originally developed by engineers with backgrounds in ML and large-scale app development, Checksum.ai uses anonymized session data from staging or production to capture sufficient coverage—often with fewer than 200 user sessions .
