# Does your source really say that? > Acurio checks your bibliography and every cited claim against the original sources. See what needs fixing before your supervisor does. ## Three questions your supervisor asks too. 1. **Does the source exist?** Acurio looks up every entry in Crossref, OpenAlex, DataCite, arXiv and DOAJ. Fabricated, incorrect and retracted sources stand out immediately. (Quick Check: free, no account needed) 2. **Does it say what you cite?** Add your source PDFs. Acurio reads the original passage for each citation and places it beside your claim. (15 citations free with an account) 3. **What needs fixing?** A finding and explanation for every citation.

Before you submit, Rich Review reads your thesis the way an examiner would. Before your defence, you practise with the questions your examiners are likely to ask. ### Rich Review: an examiner-style report on the whole thesis (Before you submit) Tell it what your thesis should achieve. Rich Review measures every chapter against that goal and shows you what holds, what is weak and what is still missing. - Optionally measured against the criteria of your grading rubric - Gaps in the argument and places where it loses its thread - The rules in your university's guidelines, and inclusive language if you want it In the Pro and Lab packs, from CHF 29 / EUR 32 / USD 36 one-time. 30 to 125 credits per review, depending on length. ### Defence questions on your thesis (Before your defence) Your thesis turns into the questions examiners are likely to ask, with links to your chapters and answer outlines. - 5 to 25 questions, from basic to committee level - Filter by methodology, evidence, scope, contribution and follow-up - More questions without repeats, export as a Word file In the Pro and Lab packs. 15 credits per question set. ## Pricing Buy credits as a balance.

Quick Check checks whether your sources exist and their details are correct. It is free and needs no account. Source verification goes further: it reads your source PDFs to check whether they say what you cite. ### Is this a plagiarism check? No. Plagiarism software finds copied text. Acurio finds claims your source does not support and sources that do not exist. The two complement each other. ### What happens to my thesis? Acurio is a Swiss company hosted in the EU (Germany). Uploads use HTTPS, your documents are not used for training, and you can delete everything with a click. ### Is Acurio a subscription? No. Buy credits once (CHF 19-49 / EUR 21-53 / USD 24-60) and use them whenever you want. There is nothing to cancel. ### Do I need Zotero? No. Acurio reads Word, PDF and LaTeX. A Zotero export (BibTeX or RIS) improves matching but is optional. ### Does Acurio replace my own review? No. Acurio shows the finding, explanation and original passage. You decide when results are uncertain. Responsibility for your thesis stays with you. ## One check before you submit. Paste your bibliography and see which entries need fixing. ## Links - [Start free](https://app.acurio.ch/auth/login?callbackUrl=%2Fdashboard&mode=signup&lang=en) - [Free bibliography check](https://app.acurio.ch/quick-check?lang=en) - [Get started guide](https://app.acurio.ch/get-started?lang=en&from=landing) --- Source: https://acurio.ch/en
