Deep UX Audits in Minutes

A UX audit is an expert-style evaluation—it inspects your product against proven UX principles (mental models, feedback loops, error prevention, visibility, cognitive load, etc.). Usability testing, on the other hand, watches real people attempt to complete tasks.

Think of it like this:

• UX audit (Krux AI) — Quickly surfaces the most likely friction, logic gaps, and clarity issues.
• Usability testing — Confirms how real users behave and validates what you should fix next.

Most teams run a UX audit first to remove obvious problems, then run usability tests to measure impact and refine the remaining details.

Krux AI blends established UX heuristics with a state-of-the-art cognitive flow walkthrough. It reviews your happy path step-by-step and evaluates each moment across:

• Recognition vs recall
• Clarity and information hierarchy
• Error prevention & recovery
• Consistency & standards
• Affordances & expected interactions
• First-run, empty state, and onboarding clarity
• Visual and microcopy comprehension
• Discoverability of secondary/hidden actions

Krux AI goes a step further: it turns any short walkthrough video, whether it’s a polished prototype, a raw screen recording, or even a narrated wireframe into a deep, prioritized UX audit.

Our flow-comprehension engine doesn’t just check heuristics. It questions the logic of your flow, identifies where users might hesitate, highlights missing states, suggests microcopy improvements, and uncovers simplifications you didn’t know were possible. You get a structured report with P0–P2 priorities, quick wins, strategic opportunities, and clear reasoning behind every callout—so you can fix issues before they become engineering tickets or churn.

Krux AI is completely input-agnostic. As long as your walkthrough clearly shows the steps being taken, we can analyze it. You’re not locked into Figma, prototypes, or live links.

Supported inputs include:

• MP4, MOV, WebM video or screen recordings
• Audio commentary is optional but helpful for providing extra context

Our engine extracts and reconstructs the flow so it can evaluate logic, clarity, and discoverability at each step. For best results, ensure UI elements and text are clearly visible throughout your walkthrough.

Krux AI is incredibly fast, consistent, and excellent at spotting UX pitfalls, heuristics violations, microcopy problems, and missing states. It recognizes imperfections in complex interactions and is able to surface them for improvement. Human UX reviewers add contextual nuance, market understanding, and deeper product strategy.

Most teams use Krux AI as a first-pass UX audit tool to eliminate the obvious friction across their flows and to understand the implications of unthought of gaps or edge cases. The report also becomes a ready-made brief for usability testing, design reviews, or stakeholder discussions.
