Keeping your section identifiable in a shared doc
The same draft-history habit that protects solo work protects group work too, if you write in a way that keeps it visible.
Write your section, don’t just edit into one
If you draft your contribution in your own pass rather than typing directly inside a teammate’s existing paragraphs, Google Docs and Word version history can attribute it to you specifically. Constant back-and-forth editing inside the same paragraph makes that much harder to untangle later.
Keep a note of who did what, separate from the document itself
A shared outline or task list assigning sections by name is useful evidence on its own, independent of what the document’s edit history shows — and easier for an instructor to read quickly than a full revision log.
If the whole document gets flagged
A single high score on a combined document doesn’t tell anyone which section produced it. If this happens, be ready to point to your specific contribution and its own history — see how an instructor is likely to approach this for what they should be doing on their end.
Raise unclear group rules before they matter
If your group hasn’t agreed on what AI assistance is acceptable for a shared document, that is worth settling with your teammates before you submit, not after someone’s section gets questioned.
