# Autopilot & AI

What ZeraBooks does on its own, what it asks you, and how to undo it.

- [How AI works in ZeraBooks](https://www.zerabooks.com/help/autopilot/how-ai-works-in-zerabooks): ZeraBooks uses AI to read your documents and judge what each transaction means. It acts when it is sure, asks you when it isn't, and calculates every number itself.
- [What Autopilot does for you](https://www.zerabooks.com/help/autopilot/what-autopilot-does): Autopilot works through your books in one pass: vendors, categories, bills and invoices, reminders, a second look, month-end and a monthly summary. It runs when you click Run now or while ZeraBooks is open.
- [Answer Autopilot's questions](https://www.zerabooks.com/help/autopilot/answer-autopilot-questions): When ZeraBooks can't tell, it asks in Needs you with one-tap answers, its best guess first. Here is how to answer, skip, and what each kind of question means.
- [Review and undo AI actions](https://www.zerabooks.com/help/autopilot/review-and-undo-ai-actions): Everything ZeraBooks does on its own is listed in Done by AI with how sure it was. Here is how to check the actions flagged for a glance, undo one, and what can't be undone.
- [Choose how much ZeraBooks does on its own](https://www.zerabooks.com/help/autopilot/choose-how-much-zerabooks-does): Pick Cautious, Balanced or Autopilot to set how sure ZeraBooks must be before it acts, and use four switches to decide what it may do by itself.
- [Month-end entries](https://www.zerabooks.com/help/autopilot/month-end-entries): Autopilot proposes depreciation, the interest part of loan payments and prepaid-expense spreads, and asks about recurring bills that didn't show up. Here is how each one works.
- [The auditor's notes and the monthly digest](https://www.zerabooks.com/help/autopilot/auditor-notes-and-monthly-digest): On every pass ZeraBooks takes a second look at your categories, flags possible duplicates and explains months that don't tie, then sums up the latest complete month.
