An app or a utility layer
SaneBox sorts mail into folders inside the mail client you already use. You train its sorting by moving messages. It reads headers; message bodies are never downloaded. Paid plans run from Snack through Dinner, with monthly, yearly and two-year billing.
Otto is an email app with calendar, tasks and an AI assistant. That is a different scope: if you want to keep your existing mail interface and add an inbox utility, evaluate that workflow separately from moving your day-to-day mail work into Otto.
Compare data use by feature
A headers-only claim should not be treated as equivalent to an assistant reading a thread to draft a reply. Otto's email assistance can use the message context relevant to your request. Review the Privacy Policy for the details of data handling.
Otto keeps core mail, calendar and tasks on Free, with an AI allowance. Read the assistant guide to understand what is proposed for approval. Choose based on the workflow and data access you want, rather than assuming the two products perform the same job.
