How AI Semantic Snapshots Replace Screenshots for E2E Testing

The Problem with Screenshots

Every AI-powered testing tool I've seen sends screenshots to the AI model. It works, but it's expensive:

  • 100KB+ per screenshot
  • Thousands of tokens to process
  • Visual recognition needed to find elements
  • 500ms-2s latency per analysis

Semantic Snapshots: A Better Way

What if instead of a screenshot, you sent the AI a structured description of every interactive element — its position, label, type, and state?

That's what semantic snapshots do. In 1ms, they extract the complete UI structure. The AI gets a machine-readable picture for a fraction of the token cost.

New: Form Validation Detection

The latest feature detects form validation rules automatically:

  • Editor type: CodeMirror, Draft.js, Tiptap, ProseMirror, Quill
  • Required empty fields: Which fields need to be filled
  • Why buttons are disabled: Infers missing required fields
  • Best input method: Recommends how to input text per framework

This means AI agents can fill and submit forms on the first try — no trial and error.
