Pricing
Last updated: 1 September 2026
The invisible-character cleaner is free and unlimited — it runs entirely in your browser and never touches our server, so there's nothing to meter. The optional AI rewriter is the one thing that does use our server, and it's the only thing an optional pass affects: €5 for 30 days or €3 for 24 hours. That's the whole price list.
Free
- Unlimited invisible-character cleaning — 431 named characters plus the entire private-use block, runs entirely in your browser, no upload, no account
- 3 AI rewrites a day, on texts up to 1200 words
- No sign-up needed for either tool
The pass — €5 for 30 days, €3 for 24 hours
One-off payment. No subscription, nothing renews, nothing is charged again. It only changes the rewriter — the cleaner is already free and unlimited, so there's nothing left to unlock there:
- 100 rewrites a day instead of 3
- Texts up to 4000 words instead of 1200
Two things worth knowing before you buy:
- One pass works on all our tools. The same pass also raises the limits on StemGrab, WatermarkNinja and the other ShinobiTools sites — see shinobitools.com.
- It doesn't change what the rewriter writes. Free and paid run the same model with the same instructions. Try the free rewrites first; that's the point of them being free.
Payment and receipts
Payment runs through our payment provider, who acts as merchant of record: they take the payment, handle VAT and send you the receipt. We never see or store your card details. Prices include any VAT that applies to your country.
A pass is stored in the browser you bought it in — there are no accounts here — so it will not show up on another device or in a private window.
Refunds
Unhappy? Mail us and you get your money back. The details are in our Refund Policy; the full conditions are in the Terms of Use.
Questions
Is the character cleaner really free with no limit?
Yes. It runs entirely in your browser and never touches our server, so there is no account, no upload and no cap on how much you clean. Only the separate AI rewriter uses our server, and that is the one thing with a limit.
How many free AI rewrites do I get?
3 a day, on texts up to 1200 words. The count resets once a day.
What does the pass change?
100 rewrites a day instead of 3, and texts up to 4000 words instead of 1200. It only affects the rewriter — the character cleaner is already free and unlimited, so there is nothing to unlock there.
Is it a subscription?
No. €5 for 30 days or €3 for 24 hours, a one-off payment. Nothing renews and nothing is charged again.
Does one pass work on your other tools?
Yes. The same pass also raises the limits on StemGrab, WatermarkNinja and the other ShinobiTools sites — one purchase, one pass.
Is my text stored anywhere?
The cleaner's text never leaves your browser. The rewriter sends your text to our server to generate a rewrite, but nothing is saved afterwards, free or paid.
