# Categories

- Page: https://longbook.app/help/categories/

Every commitment can carry one category, and its charges take it. The dashboard, your monthly reports and your AI use categories to group spending the same way each month.

## What comes with longbook

Categories for subscriptions, streaming, rent, EMIs, insurance, salaries, utilities, education and more, each with its own icon. Any other category is added by name. A category is optional.

## Where you use them

- **Dashboard**: the **Categories** card totals the month by category with each one's share. Tap a tile to see that category's charges.
- **Reports**: each monthly report has the same breakdown.
- **All charges** and **Commitments**: filter by category.

## Rename or delete

**Edit Category** lists every commitment in a category, and a rename updates all of them. Press and hold a category in the commitment form, or right-click on Mac. A category you added can be deleted. Its commitments keep their money and lose the label.

## Questions

### Can a charge be in two categories?

No. A commitment carries one category and every charge takes it. Commitments without one are grouped under **No category**.

### How are statement lines categorised?

The import suggests a category for each line, from your categories and longbook's own, or leaves it empty. You can change any of them in the review before anything is added.

### Can my AI set categories?

Yes. Your AI reads the categories you use and sets one on what it adds. Ask it: "Categorise my longbook". It shows you the ones it guessed, and every change waits in **Proposals**.

### Can I tidy all my categories at once?

Ask your AI: "Reorganise my longbook". It gives every row a category and merges doubles. Amounts and dates are never touched.

Still have a question? Open **Support** in the app, under **Settings**, then **Help & about**, or write to contact@longbook.app and a person answers.
