Real-time monitoring that helps you ship with confidence

Many educators I know have told me that ChatGPT is making their lives very hard, since students are using ChatGPT (and similar) to write their assignments. There are "AI detectors" on the market, but they have too many false positives and there are even tools out there designed specifically to trick them (e.g., https://www.stealthgpt.ai/). I built Revision History with a different approach in mind... instead of trying to detect AI using the text of a document, I let teachers visualize the edit history of the document (currently works with Google Docs). What was copy/pasted? How long did students actively work on the assignment? There is even a feature to watch a video of the student typing out the assignment.
