Conch

Conch is a writing and study assistant built around three functions: drafting, studying, and evading AI-content detectors. On the writing side it produces drafts, paraphrases and simplifies text, generates citations, and offers several rewriting modes. On the study side it turns lecture recordings, PDFs, and notes into flashcards, summaries, mind maps, and podcast-style audio, and it includes a chat mode for tutoring and quick answers. Its most distinctive feature is a built-in AI detector and humanizer, marketed as a way to check for and bypass detection by services like GPTZero and Turnitin. This makes Conch useful for producing text that reads as human-written even when AI-assisted, but it also means the tool sits in ethically contested territory for academic use, since evading plagiarism and AI-detection systems can conflict with a school's honesty policies. Conch is aimed at students, researchers, and academics, and reports a user base of over 2 million academics. It runs in the browser with a Chrome extension for quick access. Free accounts get 10 credits per day across all tools; paid plans run $30 monthly, $21/month billed quarterly, or $12/month billed yearly, all with unlimited words and no daily caps. The tool is operated by Yofi Tech, LLC.
