Summaries are a starting point
Gmail includes free conversation summaries, Help me write and Suggested Replies since January 8, 2026. If those tools meet your needs, start with what is already available in your inbox.
Otto's scope is mail, calendar and tasks for Gmail and Outlook. It offers an assistant that can prepare a reply or a calendar action for your review, alongside the controls for doing the work yourself. That workflow is the reason to evaluate Otto; a summary alone does not establish a need for another subscription.
Test the step after the summary
Open a thread, identify a follow-up and decide whether it needs a reply, a task or a meeting. In Otto, the selected account determines which calendar and task service is used. Google Tasks and Microsoft To Do are supported for their respective accounts.
Gmail integrates Google Calendar and Google Tasks. Google AI Pro ($19.99/month) or Ultra adds ask your inbox and Proofread; Workspace business plans include Gemini from Starter upward. Read the calendar guide and task guide to compare Otto's workflow.
Questions, answered
Are Gmail summaries free?
Yes. Conversation summaries, Help me write and Suggested Replies are free since January 8, 2026. Ask your inbox and Proofread require Google AI Pro ($19.99/month) or Ultra; Workspace business plans include Gemini.
Why evaluate Otto if I already have Gmail?
Consider Otto if you want to work across mail, calendar and tasks, or use Gmail and Outlook in one app. Try the workflow you need rather than assuming a summary requires another paid tool.
Does Otto replace my email account?
Otto connects to your Gmail or Outlook account. The selected account supplies the context for mail, calendar and tasks.
