Undetectable brings humanizing, AI text analysis, and everyday writing tools into one focused workspace. Rewrite a draft, review how it reads, and see what changed before you copy the result. HUMANIZE YOUR WRITING Turn stiff or repetitive AI-assisted drafts into smoother, more conversational text. Choose a tone, select a rewriting strength, and refine wording for essays, emails, articles, captions, and more. CHECK AI-LIKE WRITING SIGNALS Analyze text for patterns associated with AI-generated writing. Review an estimated human-likeness score, explore writing signals, and identify passages that may deserve a closer edit. Results are estimates, not proof of who wrote the text. COMPARE EVERY CHANGE Switch between your original text, the rewritten version, and highlighted changes. See what was adjusted while keeping control over your final message. MAKE IT SOUND LIKE YOU Create a personal writing voice from samples of your own writing. The app uses those examples to guide word choice, sentence length, and style in future rewrites. MORE WAYS TO IMPROVE TEXT • Paraphrase and reword • Fix grammar • Summarize long text • Shorten wordy paragraphs • Expand ideas • Translate into 20 languages BUILT FOR YOUR WORKFLOW Paste or type text, import a file, or use the scan option. Save work in your library, revisit recent drafts, and copy finished text when you're ready. Available for iPhone, iPad, and Mac, with layouts designed for each screen. Whether you're polishing an email, editing an article, or making an AI-assisted draft feel more personal, Undetectable helps you write with greater clarity and control. Important: AI detection scores are probabilistic indicators and should not be used as the sole basis for judgments about authorship.
