AI detectors can flag writing that a student wrote entirely on their own, and a high score can be stressful even when you've done nothing wrong. The best protection is evidence of your writing process: drafts, timestamps and a record of how the text was typed. Here's how to build that record before you submit, which tools can help, and what to do if you're accused.
Draft in Google Docs, or in Microsoft Word with the file saved to OneDrive. Both keep a version history with timestamps, which shows your essay growing over time. Files saved only to your computer, or written in an app and pasted in at the end, leave much less of a trail.
Tools like Grammarly Authorship and GPTZero's Writing Replay record how a document was written, including what was typed and what was pasted. They only help if they're on while you write, so set them up before your first sentence.
Save your notes, outline, source list, PDFs you annotated and early drafts. In Google Docs you can name key versions (File > Version history > Name current version), such as 'outline' or 'first full draft'.
If you draft part of an essay somewhere else, such as your phone's notes app, keep that file too. A big unexplained paste is exactly what process reports highlight.
If your instructor allows AI for brainstorming or grammar checks, say how you used it, and keep the chat history. Being upfront is much easier than explaining later.
Ask what the concern is based on, share your version history or a process report, and offer to talk through your argument and sources. Learn your school's academic integrity process and your right to appeal. AI-detection scores are estimates, not proof.

Best for: a shareable report and replay of how you wrote your essay
Grammarly Authorship is an opt-in feature that tracks your writing process as you work. It labels text as typed by you, pasted from another source, or AI-assisted, color-codes your document by source, and lets you replay your writing from the first idea to the last keystroke. It works in Google Docs (with the Grammarly browser extension), in Microsoft Word (with the Grammarly desktop app) and in the Grammarly editor. Authorship is available on both Grammarly Free and Grammarly Pro; Pro and Grammarly for Education plans add extras such as citations for attributed sources and AI and plagiarism detection flags in reports. Grammarly doesn't send your report to anyone automatically — you decide whether to create a share link and send it to your instructor.
Why students use it:
Grammarly Authorship is our top pick because it's free and works in both Google Docs and Word, but no tool can guarantee an instructor will accept it. Use it alongside your drafts and notes, and follow your course's AI policy.
Best for: a free, always-on record of your drafts
Google Docs automatically saves a version history you can't turn off. Open it with File > Version history > See version history to see edits with timestamps, and name important versions as you go. For an instructor to browse the history, you need to share the original document with them with Editor access — people with Viewer or Commenter access can't see it.
Why students use it:
Best for: students who write in Word
If you save your Word document to OneDrive (or SharePoint), Word keeps earlier versions you can open, compare or restore — click the file name at the top of the window and choose Version History. Word for the web is free with a Microsoft account, and students with an eligible school email can get Office 365 A1 (web versions of Word, Excel, PowerPoint, OneNote and Outlook) free from Microsoft. Word's Track Changes can also mark edits as you revise.
Why students use it:
Best for: replaying a Google Doc's editing history
GPTZero offers a free Chrome extension that builds a playback of a Google Doc from its revision history. It shows editing sessions and pastes on a timeline, with cards showing how much text was pasted and when, plus a typing analysis. You can share a Writing Report link with your instructor. GPTZero's Writing Replay can also be turned on for other writing platforms such as Canvas and Notion.
Why students use it:
Best for: watching a Google Doc's revision history play back like a video
Draftback is a Chrome extension that replays the revision history of any Google Doc you can edit, with play, pause, rewind and real-speed playback, plus a page of insights about time spent writing. It offers a 30-day free trial without a credit card, followed by a paid subscription.
