£0.
Forever.
No account, no trial, no "upgrade to unlock." The free product you're using today stays free — that's the commitment.
The short version
Free, unlimited, no sign-up required. 10,000 characters per pass. Re-run as many times as you want. Every feature available to every visitor. No "pro" tier hidden behind a paywall, because there isn't one.
How this works economically
Running a humaniser costs money. Specifically, it costs a few tenths of a pence per pass in model inference, plus trivial bandwidth and compute. The total operating cost of this site is, compared to a coffee habit, modest.
We pay the model costs. The site supports itself through a partner integration we don't bolt onto the humaniser experience — you won't find it shoved into your results, jammed above the textarea, or disguised as an "upgrade prompt." If you're curious about the partner, look for it quietly in the footer. If you're not, you'll never notice it's there.
Why not just charge £15/month like everyone else?
Because we've used the alternatives and they were worse. They synonym-swapped, they threw "moreover" into every paragraph, they billed monthly for a quota most people hit in an afternoon, and they positioned the underlying problem as if using AI for drafting is something shameful that needs hiding.
AI is in your keyboard, your search bar, your email autocomplete. The useful question isn't "is this person using AI?" — it's whether what they wrote is good, accurate, theirs to claim, and appropriate for the context. A humaniser helps with one slice of that. It shouldn't cost £15/month.
What you get
- Unlimited passes. No daily, weekly, or monthly cap.
- 10,000 characters per pass. Break longer work into sections — quality is better in focused chunks anyway.
- Three rewrite strengths. Light, standard, aggressive. Pick what the text needs.
- Tested against five detectors every release. GPTZero, Turnitin AI, Originality.ai, Copyleaks, Winston AI. Median pass-rate above 85% on our internal test set — we don't promise 100% because no honest tool does.
- No account, no email, no card. Open the tool, paste, rewrite, leave.
- No storage. Text is processed in-memory on the edge and discarded. We don't train on submissions. We don't sell paste data. Full detail in privacy.
What we don't offer (and why)
No API. Not yet. It's on the roadmap — when we ship it, personal use will be free with sensible rate limits, and high-volume commercial use will pay a price that covers inference. The free web tool stays free either way.
No team accounts. The free tier already serves this use case — five people on the same team can each open the tool and paste, at no cost, without coordinating anything.
No "enterprise" tier. If you have a legitimate enterprise need (compliance review, procurement paperwork, custom SLA), write to hello@humaniseai.ai and we'll figure it out. Not every company needs a £5,000/year contract for a 10,000-character textarea.
The commitment in writing
If we ever add a paid tier — for additional features, higher character limits, or anything else — the free product you're using today stays free. We won't grandfather you into a worse version. We won't gate what currently works. We won't retroactively impose limits.
If that ever changes, we'll tell you clearly, in plain language, on this page, and the change will only affect new capabilities we add — not what already exists.
