FreeDetect Hub

Use the text area at the top of the page. Paste directly or upload a .txt, .md, .docx, .pdf file. Your text stays entirely in your browser — nothing is sent to any server.

Use the chip filters to narrow the tool grid. Start with Beginners for quick free checks; switch to Professionals for deep academic or code analysis. Filter by category — AI, plagiarism, bibliography, image, etc.

Your text is automatically copied to the clipboard. Each tool opens in a new tab — just paste with Ctrl+V / Cmd+V. Run at least two or three tools before drawing conclusions.

False positives are real and common. If two out of three independent detectors agree, that's a meaningful signal. A single flagged result is not proof of anything.

Open the Citation Generator panel inside the text area. Click Scan input text — it finds all DOIs in your text and checks each one against Crossref. Any ❌ result is a potentially invented source.

Paste any DOI or ISBN into the Citation Generator and hit Fetch to get APA, MLA, Chicago, or BibTeX output instantly. For full reference management, use Zotero (Pro tier).

Use the bibliography tools — Retraction Watch, Scite.ai, Crossref — to confirm that cited papers exist, haven't been retracted, and actually say what you claim. Be honest about any AI assistance.
