If you've been shopping for an AI UX audit tool, you've probably come across both Klyxx and Krux AI. They sit in the same category, serve similar audiences, and cost roughly the same. But the way they actually work is different enough that the right choice depends entirely on where you are in your product lifecycle and how much friction you're willing to accept to run an audit.
This is an honest comparison — including where Krux is the better fit.
How Krux AI works
Krux is built around walkthrough videos. You record a screen capture of your product flow — a dashboard, onboarding sequence, settings page, checkout — narrate it as you go, and upload the video. Krux analyzes every frame, evaluates the flow step by step, and returns a prioritized audit covering clarity, navigation, microcopy, interaction patterns, and usability issues. Reports typically come back within a few minutes.
The video-based approach gives Krux a real advantage for interaction-heavy flows. Because it watches you move through the product, it can catch issues that only show up during actual use: confusing state transitions, missing loading feedback, flows that break down mid-task. Things that don't exist in any single static frame.
Krux pricing runs from $7.99 to $12.99 per month, and they offer a free plan to get started.
How Klyxx works
Klyxx is built around screenshots. You upload an image of any interface — a landing page, app screen, checkout flow, dashboard, mobile view — and it runs a structured analysis across 16 UX dimensions: visual hierarchy, CTA prominence, cognitive load, accessibility contrast, conversion friction, onboarding clarity, trust signals, and more. Findings come back as a prioritized report grouped by severity, with scores on each dimension and paste-ready fix prompts you can drop directly into Cursor, Lovable, Bolt, v0, Banani, Claude, or ChatGPT.
The screenshot-based approach has a different advantage: zero friction to run an audit. There's nothing to record, no flow to walk through, no narration required. You drag a screenshot in and get structured feedback in under a minute. That means you can audit a landing page before it's even wired up, evaluate a design file before it's built, or quickly check a single screen you shipped last week.
Klyxx pricing starts at $12/month for 10 audits, with a $5 one-time option for a single audit if you want to try it first.
The core difference
The simplest framing: Krux watches you use your product. Klyxx looks at what your product looks like.
Neither approach is universally better — they're suited to different questions.
| | Krux AI | Klyxx | |---|---|---| | Input | Walkthrough video | Screenshot | | Friction to run an audit | Medium (record + upload) | Low (drag and drop) | | Best for | Interaction flows, live products | Visual/UI issues, pre-launch, static screens | | Works pre-launch | Yes, with a prototype | Yes, on any image | | Catches interaction issues | Yes — watches the flow | Limited — static snapshot | | Catches visual/layout issues | Yes | Yes, with more depth | | Structured severity scoring | Yes | Yes | | Implementation prompts | No | Yes — 7 tools (Cursor, Lovable, Bolt, v0, etc.) | | Pricing | $7.99–$12.99/mo | $5 one-time / $12–$59/mo | | Free plan | Yes | $5 one-time entry |
Which should you choose?
Krux is the better fit if:
- You're auditing a live, interactive product where the flow matters as much as the visuals
- You want to capture bugs and broken states that only appear during actual use
- You're comfortable recording a walkthrough and have a few minutes to do it
Klyxx is the better fit if:
- You're pre-launch and working from designs or early builds — no live product needed
- You want instant feedback with no recording friction
- Your primary concern is the visual layer: hierarchy, CTA clarity, conversion friction, accessibility, trust signals
- You're a vibe coder using Cursor, Lovable, Bolt, or v0 and want paste-ready fix prompts to act on findings directly
- You want to audit a specific screen quickly without walking through a full flow
The honest overlap: for visual and layout issues on a real product, both tools will surface similar problems. The difference is workflow. If recording a walkthrough feels like a barrier — especially if you want to check something quickly or you're working from a design that isn't fully interactive yet — Klyxx removes that friction entirely.
Plenty of teams will eventually want both: Klyxx for fast, low-friction visual checks throughout the build, Krux for a deeper interaction-layer audit once you have a live flow to record. They're not really competitors so much as tools for different moments.
Audit your interface before users do. Upload a screenshot and Klyxx gives you a structured, prioritized UX audit across 16 dimensions — with paste-ready fix prompts for Cursor, Lovable, Bolt, and more. Try Klyxx free.
