# aiToneRules

> Returns the workspace's AI tone rules, which guide how Plain's AI features phrase replies. Use the optional `isEnabled` filter to retrieve only active rules. Pagination is supported via standard `first`/`after` and `last`/`before` cursor arguments, though in practice all rules are returned in a single page. Requires the `aiToneRule:read` permission.
