Your CRO agent audits any landing page in 60 seconds.
And ships the fixes — no developer.
Your CRO agent for founders, marketers, and operators shipping landing pages. CROW scores, prioritizes, and applies fixes the way an analyst would — no developer, no CMS access. Grounded in the MECLABS conversion heuristic.
CROW is a CRO agent that audits your page against the heuristic — developed by MECLABS Institute over 15 years and $100M+ of research — then deploys AI-generated fixes via a single script tag. Free audit, no signup.

Your site, your control
crow.js is built like QA software — every change is reviewable, reversible, and scoped.
Preview before publish
Every generated fix shows a live preview of the page with the change applied — before it ships.
One-click pause or delete
Disable any fix or remove it from your dashboard with one click. Confirmation before delete.
Queue, don't auto-ship
Fixes never apply without your explicit approval. You click Apply Fix per issue — nothing happens otherwise.
Scoped to what you approved
crow.js only modifies the specific selectors and content you saved. It can't touch anything else on your site.

Common questions
Is it really free?
Yes — no credit card and no account needed to audit a page. You only create a free account when you're ready to deploy fixes to your live site. Free during beta for single-page audits; paid plans for bulk analysis and team features are coming later.
What data do you collect?
We don't store your URLs or page content on our servers. The page is fetched and analyzed in real-time, then discarded. Anonymous audit counts are tracked. Your page content is sent to Anthropic's API per their privacy policy.
How is CROW different from Google PageSpeed Insights or Hotjar?
PageSpeed measures technical load speed. Hotjar shows session recordings. CROW analyzes conversion psychology — why visitors aren't taking action — scored against the MECLABS conversion heuristic, an industry-standard framework developed by MECLABS Institute.
How does "Apply Fix" work — how can it change my site?
After your audit, click "Apply Fix" on any issue. Claude reads your page HTML and generates a precise CSS selector + DOM change (replace text, swap a button color, inject a trust badge, etc.). Install one script tag on your site — crow.js fetches your queued fixes from our server and applies them on every page load using standard DOM mutations. It works on any website regardless of CMS or framework.
Does it work on any page?
Any publicly accessible page — landing pages, product pages, homepages, checkout flows. It can't access login-gated or password-protected pages.
