Terms of service

Last updated: 2 November 2026

1. Who you are dealing with

These terms are between you and Unmark-AI (unmarkclaude.io), "we". Your payment is taken by lava.top, the merchant of record for this purchase, and that is the name you will see on your card statement. The work and the support are ours: hello@unmarkclaude.io.

Claude is a trademark of Anthropic PBC. Unmark-AI is not affiliated with Anthropic, OpenAI or Google.

2. What the service does

The check. You paste a text or send a file, and we score how much it reads like AI, from 1 to 10: 1 or 2 reads as human-written, 3 to 6 shows signs of AI, 7 to 10 reads as AI-written. You also see the phrases a reader would notice. The check is free, covers the whole document and needs no account.

The fix. If a text of up to 3,000 words scores 3/10 or higher, you can pay to have it brought below 3/10. We rework the wording, keep your facts, and run the same check on the result, so you see the score before and after. If it does not get below 3/10, you get your money back (section 8). A longer document can be sent for fixing in parts of up to 3,000 words, each under the same guarantee.

What we take: English prose from 50 to 25,000 words, pasted or as a .txt, .md, .docx, .odt or .pdf file up to 15 MB. A text mostly in another language, a scanned PDF, code and images get no score, and a text that is mostly verse gets a score but no fix. Each of these is turned down before anything is created, so it costs you nothing.

3. What we promise

• The check is free for the whole document, with no account.
• The fix brings a text of up to 3,000 words below 3/10 on our check, or you get your money back in full (section 8).
• Every figure, date, name, link and term in your text is matched against your original, and a passage that would lose one keeps your wording.
• A .docx or .odt document comes back as the same kind of file, and a PDF comes back as a .docx with the same paragraphs; headings, lists and tables stay where they were. Inside a paragraph, bold or italic can even out to whatever that paragraph starts with, and text in boxes and footnotes is left exactly as it was. The file's author, dates and the program that made it are cleared. Pasted text comes back on screen and as a file you can download.
• Invisible characters and look-alike letters are taken out of the fixed text.
• Your text never goes to OpenAI, Anthropic, Google or any AI detector. The check runs on our own server, and the fix runs on an open-weight model on hosting that keeps nothing (see the privacy policy).
• We don't ask where a text came from or what it is for, and we don't turn it down for its subject.

4. What the score means, and what we do not promise

The score says how a text reads to our check, not who wrote it. Some human writing reads as AI, and no checker, ours included, can prove who wrote a text.

We make no promise about what any other detector, platform, school, client or employer will conclude about your text. We never send your text to them, so we don't guess.

5. What you may use it for

By sending a text you confirm that it is yours or that you have the right to process it, and that you follow the rules of wherever you submit it.

6. Price and payment

One payment per text. $5 for a text of up to 3,000 words. A longer document you fix in parts, each with the same guarantee. There is no subscription and nothing to cancel.

Payments are processed by lava.top, which acts as the merchant of record for the transaction. We never see or store your card details. The price on the button when you pay is the price that applies.

7. Delivery

The fix starts as soon as the payment lands. Before you pay, the page tells you the time it will be ready within; after, it shows how far along it is. When it is ready, a link to your result goes to the email address you give at checkout. The link works for 30 days, after which your text and the result are deleted (see the privacy policy). Download what you need before then.

8. Refunds

Our guarantee. When the fix is done, we run the same check on the fixed text. If it scores 3/10 or higher, we refund the full price. You don't need to ask: the result page and the email tell you, and the refund goes out through lava.top within 5 business days. When it shows on your card depends on your bank. The fixed text is yours to keep.

If the fix never arrives, or the file comes back broken, write to hello@unmarkclaude.io and you get your money back in full.

For anything else about your result, write to hello@unmarkclaude.io: a person reads every message.

9. Availability and liability

The service is provided as it is. We do not guarantee uninterrupted availability. Our liability for any claim connected to your use of the service is limited to the amount you paid for the order in question.

10. Changes

These terms may be updated. The version in force is the one published on this page at the time of your payment, and the date at the top tells you when it last changed.

11. If something goes wrong

Write to hello@unmarkclaude.io first: nearly everything is settled the same day, and a refund is faster than a dispute. Anything about the payment itself also goes through lava.top, under the rules you accepted at checkout.
