Questions about our tools
Yes. The seven free tools need no account and no payment. Tools that look up records online, such as the DOI lookup in the citation generator, have a fair-use limit on how many requests one connection can make in a few minutes.
The writing coach analysis, document check and AI usage statement run in your browser, and nothing you type is uploaded or stored. The citation generator keeps your source list in your browser only and sends just a DOI you look up. The source check sends each reference to Crossref through our server to find the record and does not save it. For paid scans, your file is sent to our scan provider, is not added to any comparison database and is deleted after the check. The paid AI writing tools send your text to Anthropic, the provider of the Claude AI model, only after payment, store it encrypted and delete it together with the result 72 hours after completion.
The free tools help you write, cite and review a draft. None of them searches the internet for copied passages. The plagiarism scan compares your document with about 70 billion public sources and gives you a PDF report with links to the matches, usually within 15 minutes, from $0.29 per page. It cannot see paywalled or subscription journals.
You paste or upload your text, see the price and pay by card. Only after payment is your text sent to Anthropic, the provider of the Claude AI model, to create the suggestions. You get a private link to the result, and every suggestion is shown beside your original. If processing fails, we refund your payment in full.
No. The free tools work without an account, and you can order a plagiarism or AI check without registering. You see the price before you pay.
