Questions
Do I have to connect every account separately?
Yes, once each. Signing in brings your first Google account; add the others from Settings, and from then on they all arrive in the same list.
Does Klorn send or delete mail on its own?
Not unless you tell it to. Lanes only sort. Sends, permanent deletes and forwards wait for your approval; an auto-reply rule you create yourself counts as that approval. With automation on, the assistant may run low-risk steps by itself. Every send leaves a receipt.
Which accounts work today?
Gmail and Google Calendar, plus Naver Mail and iCloud Mail in beta. That’s the full list today; this page changes the day another account can be connected.
Where does my mail go?
To Klorn’s classifier and back. Tokens are encrypted at rest, and the code that touches them is public. If you’d rather hold it yourself, run Klorn on your own server.
What does “bring your own AI key” mean?
Klorn can use your own key from a model provider instead of ours. That works on Pro. Self-hosted installs can use any key or a local model.
Is there a Windows app?
Yes, in beta. Windows may show a SmartScreen warning on first launch until the app is code-signed. The web app works in any modern browser with the same account.
