"Honesty is the first chapter in the book of wisdom." - Thomas Jefferson
Traditional AI detection tools rely on unreliable algorithms that produce false positives and false negatives, creating an adversarial relationship between teachers and students. Papertrail takes a different approach.
Instead of flagging work as "suspicious," we provide complete transparency into the writing process: every keystroke, every revision, every pause. We present comprehensive visualizations and unbiased statistics that tell the full story of how a document came to be.
You know your students and their writing habits better than any algorithm ever could. We simply give you the tools to verify authenticity with confidence.

Enterprise-grade security with full GDPR compliance. Encrypted data storage, right to deletion, data portability, and comprehensive audit logs for student privacy.
Current AI detection tools produce unacceptable error rates that harm students and undermine trust
Traditional AI detectors incorrectly flag up to 61.3% of authentic work written by non-native English speakers, particularly evident in TOEFL essays evaluated across multiple detectors.
AI-generated text can evade detection 82.6% of the time (accuracy drops to just 17.4%) when manipulated with basic techniques like paraphrasing or introducing typos.
Papertrail eliminates these problems by showing you the complete writing process: no unreliable algorithms, no false accusations.
Everything you need to know about Papertrail
Papertrail isn't looking for copy-and-paste events, it's looking at how writing happens.
When a student genuinely writes, their process includes pauses, revisions, backspacing, rephrasing, false starts, and uneven pacing. Even when someone types out AI-generated text manually, their behavior tends to be unusually smooth, consistent, and linear compared to authentic writing.
Papertrail captures the full writing process over time, not just the final text. This means teachers can see things like how long a piece took to write, when edits were made, and how the text evolved. For example, an essay that appears fully formed in five minutes may reasonably raise questions, not because an algorithm "flags" it, but because the timeline itself doesn't match typical student writing behavior.
To convincingly reproduce an authentic writing process, a student would need to spend a significant amount of time slowly transcribing, introducing revisions, and mimicking natural hesitation. At that point, the incentive of a quick shortcut largely disappears; it would often be faster and easier to simply write the essay themselves.
This is exactly the proposition of Papertrail. It doesn't claim to make final judgments or replace educators with an algorithm. Instead, it provides transparent, process-level data so teachers can apply their own professional judgment and context when evaluating student work.
Papertrail is fully GDPR compliant with end-to-end encryption, data minimization principles, and comprehensive student consent workflows. All data is encrypted at rest and in transit. Students have the right to access, export, and delete their data at any time. We maintain detailed audit logs and store data on EU servers for European institutions.
Students access assignments through a simple web-based editor with no downloads or installations required. Teachers create assignments and share unique links with their students. The editor works in any modern browser and automatically saves revision history as students write. It's intuitive and requires no technical knowledge.
Papertrail works standalone with no LMS integration required. Teachers simply share assignment links with students through whatever communication method they prefer (email, LMS announcements, etc.). However, we're actively developing LTI integrations for major platforms. Contact us if you're interested in early access to LMS integrations.
Papertrail works on all modern browsers (Chrome, Firefox, Safari, Edge) on desktop, tablet, and mobile devices. For the best experience, we recommend desktop or laptop computers for writing assignments. The analysis dashboard is optimized for larger screens but remains accessible on tablets.
Traditional AI detectors analyze finished work and make probabilistic guesses about whether it's AI-generated, leading to high false positive and false negative rates. Papertrail takes a completely different approach: we track the entire writing process from start to finish. Instead of accusing students, we give you transparent evidence of how the document was created, letting you make informed decisions based on facts, not algorithms.
Students can save their work and return to it anytime before the deadline. All keystrokes and revisions are continuously tracked across sessions. The timeline visualization shows when work occurred, including breaks between writing sessions. This actually provides richer data about authentic writing patterns.
Yes, paste events are tracked and clearly visible in the analysis. Large paste operations appear as distinctive large bubbles in the timeline chart and show up instantly in the revision history. This transparency is exactly what makes Papertrail effective—you can see when and what was pasted, then investigate further if needed.
Yes! All users receive a 30-day free trial with full access to all features. This gives you time to test Papertrail with your teachers and students before committing to a license. No credit card required to start your trial.
Yes! Papertrail tracks keystrokes and revision history for any language. The interface currently supports English, Dutch, German, French, Spanish, and Italian, and the analysis works identically regardless of the language students write in. We are actively adding support for more languages and can accommodate additional language requests for institutional customers.
If you exceed your license limit, please contact us at support@papertrail-app.com. In almost all cases, we are generous in providing the required extra licenses at no additional cost for the remainder of the year.
Disclaimer: While we strive to accommodate all requests, we are not legally bound to provide additional licenses if we suspect intentional behavior in setting a lower license limit to circumvent our pricing.
Feedback from teachers using Papertrail in their classrooms
It's been genuinely helpful for understanding how students approach their writing, and it's helped start better conversations with students about their work.
I like that it supports professional judgment instead of trying to replace it. It's one of those tools that supports teaching rather than complicating it.
