Frequently Asked Questions

Absolutely. tonal does not store, log, or track your text. It forwards your inputs securely to the AI model and returns the rewritten draft. All tonal UI components are encapsulated within an isolated Shadow Root, keeping them completely safe from host page scripts.
tonal has dedicated adapters for Gmail, Slack (Web), and LinkedIn to seamlessly match their unique message inputs. For all other sites, tonal's Default Adapter automatically detects any standard text input or textarea (such as Twitter/X, GitHub, Notion, etc.).
