Sentinel by NEMO is a no-code E2E testing platform that records frontend interactions and uses AI to generate Playwright tests. The desktop app captures clicks, video, and voice annotations to build self-healing tests that verify both functionality and UX state transitions. It aims to make E2E testing 100x faster with zero manual coding.

Problem
Traditional E2E testing relies on manual clicks, brittle scripts, and visual-only checks that miss state transitions and complex motion. This approach lacks context on why a test exists, making it difficult to verify smooth transitions or align state changes with human intent, slowing down high-velocity development teams.
Solution
Sentinel by NEMO provides a no-code desktop app that records frontend interactions and generates AI-powered Playwright tests in seconds. The tool captures clicks, video, and voice annotations to map every state transition, ensuring tests understand both functionality and UX. Its AI engine uses robust selectors and self-healing heuristics to maximize test reliability, while parallel execution across the stack supports CI integration. This shifts teams from manual scripting to an AI-driven workflow, enabling faster, more reliable shipping.
Target Audience
Primary users are software development teams, particularly engineers and QA professionals at high-velocity startups and fintech companies, who need to accelerate E2E testing without sacrificing reliability or context.
