Stable v1.0

UI UX Autopsy

Upload a session trace, run a critique, and get back a terse, opinionated UX readout with friction points, hesitation moments, and concrete product fixes.

Input

Event logs support native JSON, PostHog, FullStory, Mixpanel, and Amplitude exports. Video stays lightweight and browser-side.

Trust

Reports show provenance, evidence snippets, and explicit fallback messaging when AI analysis degrades to heuristics.

User goal

Outcome-level goal — what success looks like for this session.

UI context

Name the product surface and step so findings read tied to that flow.

What are you investigating? (optional)

If empty, the report stays generic relative to your hypothesis.

Accepted formats

`Event log`: native `{ events: [...] }`, PostHog export, FullStory export.

`Video`: MP4, QuickTime, or WebM — max 5 minutes. Frames are sampled in-browser; no heavy CV pipeline.

`Motion signal`: deltas measure large visual transitions (scrolls, route changes, modals). Fine text entry and cursor movement register as near-zero motion — not a stall. Pasting click timestamps below sharpens interpretation.
