Use this as visual context before generating UI.

AI-ready workflow

Stop asking your agent to guess the design system.

Inspect the real page

Hover and pin the live element you care about, including normal authenticated app screens.

Copy DESIGN.md

Generate Markdown context with YAML tokens, colors, type, spacing, radii, shadows, variables, and agent instructions.

Prompt with evidence

Copy CSS, HTML, component bundles, and AI prompts grounded in the selected element.

Edit in context

Tweak declarations directly on the page, then move the proven values into your codebase.

Positioning

For developers using Cursor, Claude Code, Codex, v0, Lovable, or Bolt.

CascadePeek keeps the first release intentionally focused: no account wall for basic inspection, narrow extension permissions, local-first page analysis, and a paid Pro license for the AI context workflows that save the most time.

Privacy posture

Local by default.

The extension runs after the user clicks the toolbar button. It uses `activeTab`, injects a local inspector into the current page, and only contacts CascadePeek servers for checkout and license activation.
