Without Sentinel

The Manual Grind

  • Humans performing thousands of manual clicks
  • Visual-only testing that misses state transitions
  • Brittle scripts that can't verify complex motion
  • Lack of context on 'why' a test exists
With Sentinel

Full Context Capture

  • Record interactions, video, and voice context
  • Automatic mapping of initial and final states
  • Verify transitions and motions with AI
  • High-fidelity tests derived from human intent
The Problem

Manual UI audits.

Teams waste hours manually clicking through browsers to verify UX, transitions, and motions. It's slow, unscalable, and prone to human error.

The Agitation

Context-less testing.

Traditional tools miss the 'feel' of the app. They can't verify if a transition is smooth or if a state change aligns with human intent.

The Solution

Full-stack Context.

Sentinel records your clicks, video, and voice to map out every state transition. Get E2E tests that understand functionality and UX.

Developer Experience

Record first.
Sophisticated.

Most of the time it is just Record, Voice, and Deploy. We built the engine for the 95% case.

A tool for making testing effortless. Move from manual scripting to an AI-driven workflow designed for high-velocity teams.
