Hey Product Hunt! 👋 I built CheckAI because every AI detector I tried had the same problem: they only solve half the equation — they tell you something is AI-generated, then leave you on your own to figure out what to do about it. CheckAI does both: detect AND humanize. On the detection side, I wanted to eliminate the copy-paste tax. The Chrome extension lets you right-click an image on Reddit, select a paragraph on any webpage, or screenshot-box anything on your screen — you get an AI score instantly without leaving the page. For heavier workflows, the web app at checkai.space handles bulk text analysis with detailed segment breakdowns. On the humanizer side, I spent months testing what actually moves AI detection scores. The Humanizer Instruct doesn't just randomly paraphrase — it offers three targeted rewrite strategies: - Sentence-level rewrites (full alternative phrasings) - Token swaps (swap individual high-risk words) - Pattern-break rewrites (restructure sentences that follow AI-typical patterns) You can review each suggestion, apply them selectively, and redetect — all in one interface. For developers: there's a REST API if you want to plug detection into your own tools. Docs at checkai.space/api-docs. I'd love to hear how you'd use this.
