Turn AI Drafts Into Content That Reads Human and Ranks
Humanize your writing, optimize it for SEO, and shape it for AI answers. See every change before and after.
Paste a draft. Our AI check shows what makes it sound machine-written. Then pick a goal: Humanize, SEO or AI answers. We rewrite the weak spots, score the new version, and show every change side by side. We edit wording only, and we never invent facts.

Frequently Asked Questions
Everything you need to know about Content Trace.
What do the three optimizers do?
After the AI check, the optimizer rewrites the weak spots it found for the goal you choose. Humanize turns generic AI drafts into clear, original writing in your voice: plain words, varied sentences, no AI filler, and markers where your own examples belong. SEO adds descriptive headings, puts the main point early and places your keyword naturally. AI answers adds a direct answer up top, question headings and passages that AI Overviews, ChatGPT and Perplexity can quote. Then it scores the new version with the same engine and shows every change side by side. You can run all three on the same text.
Will Humanize make AI text undetectable?
No, and we do not promise that. Humanize edits wording so a draft reads naturally. It never invents personal stories, opinions or facts to push the score up, so the Human Score may move only a little. Reading ease usually improves most. The biggest gains come from the real details you add where we place [Add: ...] markers, because specific, first-hand detail is what makes writing human.
Does the optimizer change my facts or guarantee rankings?
No. The optimizer keeps your facts, numbers, names and quotes, and it does not add opinions or feelings you did not write. A fact check compares the new version with your original and flags anything that changed. No tool can guarantee rankings or AI citations, so review every change before you publish.
Is it free?
Yes, to start. You get 5 free checks a month for texts up to 10,000 characters, with no account and no credit card. An AI check uses 1 and each optimizer run uses 2. For longer texts and more runs, Pro is $6.58 a month billed yearly ($79) or $12 month to month, or you can buy a one-time Word Pack.
How does the AI check work?
It scores your text across 8 sections and 32 signals, from sentence rhythm and word choice to voice and reasoning patterns, and adjusts for the type of content. You get a Human Score out of 100 with every signal explained. No AI detector is 100% accurate, so treat the score as an indicator, not a verdict, especially for short or heavily edited texts.
Can I use it for academic work?
Educators can use the AI check to review student work, and students can use it to review their own writing. Results should not be used as sole evidence in academic disciplinary proceedings. AI detection is probabilistic, and a low Human Score does not prove AI authorship.
Does Content Trace store my text?
Only if you sign in. Signed out, your text is processed in real time and is not stored, logged, or used to train any models. When you are signed in, each analysis and optimization is saved to your private history so you can come back to it. Only you can see it, and you can delete any item at any time. We never use your text to train models.
