How is this different from Lighthouse?

Lighthouse grades speed and SEO. We grade trust. Different problem, different output. Run both, they don't overlap.

Does it actually catch AI-generated copy?

Yes. We grep against 30+ tell-words pulled from indie-hacker reviews and high-converting SaaS pages. False positives happen on purpose, you click through and decide. The grep is dumb but consistent, which is what you want for a checklist.

Will this work on a one-page Notion site or Carrd?

Yes. Anything reachable by a public URL with HTML works. Notion published pages, Carrd, Framer, Webflow, hand-rolled, all fine.

Do you store my page content?

Cached for 24 hours so you can reopen the report. Then deleted. We never train on your copy and we don't share it.

Will this be no-charge when it launches?

No. The plan is $4.99 lifetime for the early waitlist on this page only, $19/month SaaS for new users at launch. The waitlist itself is the only thing that's no-charge, joining with your email is the signal I need.

Why $4.99? Most landing audits cost $200.

Because the 80% you actually need on a v1 landing is automatable. Pattern-match 30+ AI cliche words, detect 5 default gradients, grade 12 trust signals. The other 20% is judgment, and I can't put that in a tool yet.

The problem

Buyers spot vibe-coded landings in three seconds.

Indie founders ship landing pages in a weekend now. Buyers can spot it in three seconds. Generic Tailwind gradients, AI-cliche copy (empower, seamless, unlock), Unsplash defaults, and zero real social proof are dead giveaways. The most common Reddit comment in r/SideProject this year: 'no one is going to trust your product.' You need to know what's tripping the buyer's BS detector before you spend another month wondering why nobody converts.

What you'd get

Four pieces, one tool.

Each piece ships in the first build for waitlist members. SaaS upgrades layer on top.

01 · feature

AI cliche grep across headline, subhead, and CTA

We grep your page against a 30+ word list pulled from indie-hacker reviews and high-converting SaaS landings (Linear, Stripe, Vercel, Anthropic). Each hit shows where it lives and a rewrite suggestion based on the matching sector tone guide. Most copy audits charge $200/hr for this exact pass.

Stock photo and default-gradient detector

Flags Unsplash defaults, AI-portrait artifacts (smooth-skin tells in founder shots), and the 5 Tailwind starter gradients every vibe-coded landing reuses. Plus default Heroicons sets and stock illustration packs. Visual tells matter as much as copy tells.

Why paid

Today's tools don't do this.

A UX consult is $150–300/hour and most don't grep AI-cliche copy. A vibe-coded landing leaks 60–90% of paid traffic for months while you can't tell what's wrong. Even one wrong cliche in the headline can drop conversion 30%.
