SlopCheck
Paste a URL or screenshot of any AI-generated landing page and get a plain-language audit flagging AI tropes (gradient soup, emoji decoration, Inter-everywhere) plus accessibility issues a non-designer can act on.
Solo founders and marketers who use ChatGPT or Claude to generate landing pages and ship them
- Visual audit scoring the page on gradient density, emoji decoration, font monotony, and rounded-card overuse
- Accessibility pass: contrast, focus rings, motion preferences, and keyboard flow
- Plain-English fix list ordered by effort, written so the user can either DIY or hand it to a freelancer
- Side-by-side 'before/after' mock-up showing a less generic alternative palette and type pairing
The Claude Design System Prompt explicitly catalogues the 'AI slop' patterns flooding websites built by founders using LLMs, and the GitHub repo blew up to 270 stars — there is clearly pent-up demand for an end-user-facing version of this checklist.
Source repo has 712 stars (not 270) and 95 forks, indicating real but moderate developer interest; adjacent Stop Slop project hit 1.8k-5.8k stars, and multiple landing page audit tools (Layzr, LandingLens, etc.) exist, confirming underlying demand.Claude Design System Prompt - GitHub ↗Stop Slop: A Claude Skill for Stripping Robotic AI Writing Patterns ↗
Crowded space: Layzr, LandingLens, Landingscore, PageRefresh, RoastflowAI all audit landing pages, and slopdetector.org, issloppy.com, sloppyjoe.io, slopdetector.me, plus De-Slop Chrome extension already target AI slop detection — only the specific intersection of AI-design-tropes + accessibility for LLM-built pages is partially open.Layzr - AI Website Audit Tool for Design, Copy, SEO & UX Fixes ↗LandingLens — AI Landing Page Auditor ↗AI Slop Detector — Free Tool to Check Content Quality ↗De-Slop - Chrome Web Store ↗
Paid competitors like Layzr and LandingLens show some willingness to pay, but a deep free tier exists (issloppy.com, slopdetector.org, De-Slop Chrome extension, plus the open-source ai-slop-check skill), pressuring price points for solo founders who are budget-sensitive.Layzr - AI Website Audit Tool for Design, Copy, SEO & UX Fixes ↗AI Slop Detector - Free Content Quality Checker | Is Your Content AI Slop? ↗
AI slop tropes evolve as models are retrained; as frontier models improve, signature tells may diminish, and the open-source prompt itself already provides the checklist for free, risking user leakage to DIY usage.Claude Design System Prompt - GitHub ↗
MVP is straightforward — URL fetch or screenshot upload plus an LLM call against a checklist already exists in the open-source ai-slop-check skill; multiple competitors prove the build is well within reach for a solo founder.Claude Design System Prompt - GitHub ↗Free Landing Page Conversion Analyzer - AI CRO Audit Tool ↗
