It’s also a fantastic way to help reduce false positives with transparent evidence to back up human writing (more on that in a moment).

Who is the Originality.ai Chrome extension for?

The Originality.ai Chrome extension is ideal for:

✓ Writers. Prove your work is actually yours. If you’re accused of using AI, now you can confidently prove it's your human writing and avoid reputational impact.

✓ Students. Discover peace of mind. Prove your assignment or essay is yours and naturally written, if you are accused of using AI or an auto-typing tool.

✓ Editors. Easily review content. Think an article might be AI or auto-typed? Confidently review AI scores and see if it looks auto-typed or naturally written.

✓ Teachers. Suspect an assignment, essay, or paper may be AI? Confidently see if it’s AI, auto-typed, or human-written to maintain transparency in the classroom.

✓ Content marketing managers and publishers. Avoid AI slop and maintain the authenticity and reputation of your publications.

Originality.ai for Chrome is a must-have tool for students and teachers looking to maintain AI transparency as AI is rapidly adopted in education.

It’s also excellent for any business that works with freelance writers, operates remotely, or produces high volumes of content, as it provides a handy, simple, and reliable check before publication.

Watch a Writer Write: Writing Replay

Once you download the Originality.ai Chrome Extension, you can click the ‘Video’ button at the top of any Google Doc to instantly gain access to a character-by-character replay of the writing process as it took place — providing full transparency.

Watch a Writer Write Features:

• AI score and plagiarism score
• Character-by-character video replay of the writing process
• See paste counts (and location)
• Character count
• Word count
• Contributors (and their contribution ratios)
• Revisions 

Built to provide writers and students with peace of mind that they can prove their writing is theirs.

No More False Positives

It can be incredibly difficult if your original work is incorrectly identified as AI-generated. 

False positives can be stressful and concerning, and while Originality.ai’s AI Checker is an industry-leading tool with low false positive rates, they can still occur.

Originality.ai is transparent about false positive rates:

• Lite 1.0.2: 99% accuracy and low false positive rates of 0.5%.
• Turbo 3.0.2: 99%+ accuracy and reduced false positive rates 1.5%.
• Academic 0.0.5: 99%+ accuracy and <1% false positives.
• Multilingual 2.0.0: 97.8% accuracy and lowered false positive rate to 2.4%.

It’s important to note that false positive rates can vary by AI detection brand and model, so it’s essential to review these before choosing an AI detector.

When false positives do happen, the impact can be significant. If the data suggests AI use, it can seem difficult to demonstrate authenticity. 

That’s where the Originality.ai Chrome Extension comes in! 

Now you can run a shareable, read-only report for both AI and plagiarism. It includes a video replay to transparently prove your content is yours (and naturally typed). This can help prevent issues from false positives.

Did a Bot or Human Write That? Discover The Most Accurate Auto-Typing Detection

What is auto-typing detection? 

Auto‑typer detection is a typing analysis feature that helps educators and editing teams identify non‑human typing behaviors or patterns (e.g., automated typing tools, scripted input, large paste events) in a composed Google Doc.

It produces a Human Typing Score and supporting insights that indicate whether a document appears naturally typed or automated.

Originality.ai vs. GPTZero: Auto-Typing Accuracy

Auto‑typed datasets from an auto-typer tool (non‑human and correctly flagged) at a 50% score threshold:

• Duey.ai: 96.15% Accuracy
• AutoQuill: 95% Accuracy
• Exam Ripper Lite: 100% Accuracy

Note: Results above are based on our current internal efficacy testing and will continue to improve as we expand the dataset’s coverage.

How does auto-typing detection work?

It uses Google Docs revision history and Originality.ai’s proprietary algorithm to analyze human-like vs. scripted typing patterns, using timing, cadence, and input dynamics rather than content. 

It computes statistical features such as inter‑keystroke timing, consistency, burstiness, paste behavior, and correction patterns from users’ typing sessions, and generates a Human Typing Score + summary insights that highlight the strongest contributing signals.

Benefits of auto-typing detection

Evaluate how content was produced, not just what the final text looks like:

• Detects automated input patterns that bypass typical content‑only detectors.
• Provides explainable insights (not just a single score).
• Improves content integrity while staying privacy‑friendly, because it relies on existing document telemetry (no video replay, no third-party recording, and no special setup required before the document is written).
• Built for real Google Docs workflows.
• Designed to work at scale with performance considerations for large documents.

This makes it ideal for:

• Academic integrity reviews: identify suspicious writing activity in student work.
• Authorship verification: validate whether the document appears naturally typed.
• At‑scale screening: flag documents for follow‑up before deeper analysis.
