De-robotize AI text in your browser. 200+ AI-tell swaps, contraction injection, em-dash cleanup, sentence-variance scoring. No API.
A browser-only tool that strips the obvious "this was written by ChatGPT" tells out of AI text. Paste your output from ChatGPT, Claude, or Gemini and get a humanized version live as you type. The engine does four things: (1) catches and replaces 200+ AI-tell phrases ("delve into" → "look at", "navigate the complexities of" → "deal with", "in today's rapidly evolving landscape" → "today", "leverage" → "use", and 196 more), (2) adds natural contractions humans actually use ("it is" → "it's", "do not" → "don't"), (3) trims em-dash overuse to a natural one-per-80-words, and (4) cuts filler sentence-starters ("It's important to note that…", "Furthermore,", "Crucially,"). Live AI-tell density score shows how robotic your text reads (0–100), and a sentence-variance score measures burstiness. Four voice presets — Light Edit, Conversational, Casual, Punchy — plus a severity override slider. Honest scope: catches surface tells (60–80% of what makes text sound robotic) without trying to fool dedicated AI detectors. Zero backend — your text never leaves your browser.
No, and this is the honest answer. Detectors that score perplexity and burstiness need real LLM rewriting to fool — that is an arms race we cannot win client-side. What this tool does well is fix the surface tells (clichés, jargon, transitions, em-dashes, formal contractions) — about 60–80% of what makes text sound robotic to a human reader. For most blogs, emails, essays and posts, this is enough.
Pure JavaScript pattern matching against a curated dictionary of 200+ AI-tell phrases, plus contraction injection, em-dash trimming, and sentence-variance analysis. Everything runs in your browser. No model, no API, no upload.
No. The entire pipeline is client-side. Your text never leaves your device — not to our server, not to OpenAI, not anywhere. We have no backend for this tool.
Light Edit catches only the most obvious clichés (delve, plethora, robust) and keeps your original tone. Conversational adds contractions and trims medium-tier jargon. Casual is the same plus em-dash cleanup, ideal for blogs and emails. Punchy is most aggressive — short sentences, no fillers, business-pitch energy.
Per-100-words count of detected AI tells. AI text typically scores 3–8 (5+ is a strong tell). After humanizing, your score should drop below 1.0 in most cases. It is a rough heuristic, not a forensic tool.
For deeper rewriting that changes structure (not just words), an LLM is needed. We may add a lazy-loaded transformers.js option in a future version — it would download a ~80MB model on demand. For v1 the regex layer is fast, free, and good enough for most users.
GPT-4 and Claude both massively over-use em-dashes — sometimes 3–5 per paragraph. Real human writers use them sparingly (roughly 1 per 80 words). The Casual and Punchy modes trim the excess down to natural frequency.
Your original text stays in the left panel and is never modified. The humanized version on the right is always derived live from your input — change a single setting and it re-runs instantly.
