Question: I need a system that integrates with my email client and calendar to remind me of upcoming events and tasks.

Addy is an AI-powered email assistant that automates and optimizes email workflows, saving you hours of time. It offers features like prioritized emails based on your preferences, daily digests of your most important tasks, follow-up reminders with drafted emails, and event reminders. Addy works with Outlook, Yahoo and Gmail, so it's a good choice if you want to use it to manage your email and calendar tasks.

If you want a calendar assistant that's a bit more specialized, fwd2cal is an open-source tool that can add events to Google Calendar by extracting the relevant information from email threads you forward to it. It can handle multiple email addresses and preserves privacy since it doesn't store emails, so it's a good choice if you want to connect your calendar to your email workflow without worrying about your email privacy.

Another interesting option is Clockwise, an AI-powered calendar optimization system that schedules meetings, tasks and deep work. It can coordinate team and company calendars to try to find a balance between flexibility and focused time, using your own preferences to figure out when is best for events. Clockwise works for a variety of use cases, including busy calendars and teams, and can save you time coordinating with others and get more work done overall.
