Free unlimited AI detector saved me hours of guessing what my prof flags.
The sentence-level breakdown makes rewriting super easy.
Chrome extension occasionally lags on massive docs.
Humanizer actually keeps my original voice intact.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Check as many drafts as you want with no daily limit and no signup. Results arrive as sentence-level highlights with a reason for each flag, so the score becomes something you can act on.
Nine modes spanning Standard, Academic, Blog, Formal and Simple plus premium options reshape sentence length and strip stock connectors while preserving the original meaning.
Adjustable rewrite tones for lighter editing and a grammar pass for polish, both living in the same account as detection so the workflow stays in one place.
Humanize, detect and refine text inside Google Docs, email, LMS and CMS editors through the browser menu instead of juggling tabs.
An extra set of no-signup browser utilities sits alongside the writing tools for people who want quick, single-purpose jobs handled without setup.
Coda One organises itself around one job: taking a draft that smells like AI and making it read naturally without changing what it says. The entry point is a detector you can use as much as you want with no signup, which highlights the specific sentences carrying machine-like patterns and explains why they were flagged. That framing is deliberate — the site openly notes a detector is evidence, not proof, so a low score means no machine pattern stood out rather than a certified human author.
From that score you move into the humanizer, which offers nine writing modes (Standard, Academic, Blog, Formal, Simple and several premium options) and works by varying sentence length and trimming stock connectors rather than rewriting the meaning. A rewriter with adjustable tones and a grammar checker cover lighter editing, and a Chrome extension pushes the same tools into Google Docs, email, learning platforms and CMS editors so there is no copy-paste loop.
Pricing is unusually explicit. The detector stays free with no daily limit; paid tiers start at $9.99/month for 30K words, $19.99/month for 100K words with no per-request cap and three brand voices, and $39.99/month for teams at 500K words. Checkout is self-serve through Stripe with a seven-day refund window. The site also publishes a library of free browser tools alongside the writing workflow.
Run a paper through the detector to see which sentences read mechanically, tighten them with the rewriter and grammar checker, and still disclose AI help where the course requires it.
Keep the speed of AI drafting but strip the stock phrasing, then check for clarity and tone before the piece goes live.
Use the humanizer to vary sentence rhythm and cut connector clichés that make long-form content feel templated.
Start free for occasional checks, then upgrade to a Business plan when daily volume, per-request limits and shared brand voices start to matter.
