An AI calendar that plans your work and life for you
Voiset pulls events from Google Calendar, Outlook, Zoom and any ICS link into one hub with separate workspaces, and you choose read-only or two-way sync per calendar.
Press a button, speak something like “Call the client on Thursday at 3,” and Voiset turns it into a properly dated task in your calendar — useful in a taxi or between meetings.
Capture notes by voice or text from any source. A note is a task without a date yet; one click turns it into a scheduled task with a priority and a place on your calendar.
Share a personal booking page so clients see only your free time and book meetings, calls or appointments, with every booking written straight back into your calendar.
