We comply with global privacy standards to keep your confidential data safe.
Many 'free' plagiarism checkers actually save the essays you upload into their permanent database, which can cause you to flag yourself for plagiarism if you submit the draft again later. We don't do that. Our Plagiarism & AI Detector is built on a zero-retention policy. We analyze the text against live web data and AI predictability models, provide your originality report, and then purge the data. Run your checks with absolute confidence.
Unlike free consumer tools that scan your documents to train their models (risking data breaches), Fynepdf guarantees your documents remain strictly yours. Verify your papers with absolute confidence.

Frequently Asked Questions
Can it detect the newest versions of ChatGPT and Claude?
Yes. The detection models are continuously updated to recognize the perplexity and burstiness patterns characteristic of major LLMs, including GPT-4, Claude 3, and Google Gemini.
What is a 'false positive' in AI detection?
A false positive occurs when a human-written text is mistakenly flagged as AI-generated. This often happens to non-native English speakers or highly formulaic writing. Our agent uses advanced thresholds to minimize these occurrences.
Will uploading my essay flag it in other checkers (like Turnitin)?
Absolutely not. We have a strict zero-retention policy. We do not save your text to any repository or database, so it will remain 100% original if you submit it to your school or publisher later.
Can I use FynePDF for free without paying?
Yes. FynePDF is free to use with no feature restrictions, only file size and usage limits based on your plan. You can use our tools without creating an account, although signing up lets you save files and access your history. If you need larger file limits, higher monthly quotas, team features, or API access, you can upgrade to Professional, Premium, or Enterprise plans.
How secure are my files and data on FynePDF?
Your privacy and security are a top priority. All file transfers are protected with SSL/TLS encryption, and uploaded files are automatically deleted from our servers after 15 minutes unless you choose to save them to your personal library. Files are stored on AWS S3 with enterprise-grade encryption, and we never read, sell, or share the contents of your documents.
