Not in a way you can rely on. ZeroTwo has no built-in feature that checks who wrote a piece of text, and what a model says about its own authorship is just more model output. ZeroTwo's Terms warn that any output may be incomplete, incorrect or unreliable, and that you are responsible for verifying it.
Why asking does not settle it
- Models can be wrong. The Terms say LLMs are not truth machines and that output may not accurately reflect real people, places or facts.
- Output is not unique. The Terms say other people who enter the same or a similar prompt may receive identical or substantially similar output, so a passage that looks familiar does not show where it came from.
- There is no built-in checker. None of the built-in tools in the message box and none of the Settings pages is an authorship or AI-text detector.
If you wrote with ZeroTwo and need to show it
Your own chat history is the better record. ZeroTwo keeps your chats until you delete them, so you can usually go back to the conversation:
- Find it. Select the search icon in the sidebar header (its label is Search chats), or press Cmd+K on a Mac or Ctrl+K on Windows and Linux. See How do I search my chats, projects, and files in ZeroTwo?
- Keep a copy. In Settings > Data Controls, the Export data row downloads a copy of your data. See How to export your ZeroTwo chats.
- Show it to someone. Open the chat and select Share in the top bar. People you send the link to must be signed in to a ZeroTwo account to open it. See How do I share a ZeroTwo chat or message?
Deleting a chat is permanent and cannot be undone, so a missing history proves nothing in either direction.
If you are reviewing someone else's work
A model's guess about authorship is not evidence. For approaches that do not rest on one, see What can educators do when students pass off AI work as their own?
