AI calendar assistants you can text: Dola, Poke, Caddy, and Ohai

Which AI calendar assistant should you try?

Start with Dola if you mainly want to create and change events by conversation. Investigate Poke if calendar requests usually arrive with email work, Caddy if you want a daily Google Calendar and Gmail brief, and Ohai if you are coordinating several people's household schedules. These are editorial starting points based on documented features, not measured reliability rankings.

The useful question is what should happen after you send a text. An assistant might remind you to book the dentist, place a dentist appointment on your calendar, or help arrange the appointment. The first two do not establish that the dentist has reserved a time. Choose the smallest completed task that would remove work from your day.

Compare calendar connections before choosing a messaging channel

Your calendar account matters more than the phone that displays it. Seeing an event inside Apple's Calendar app does not tell an assistant which provider owns that event. Check the account and the particular calendar you intend to change during setup.

Dola: start with a simple event and one correction

Dola's feature documentation describes creating, deleting, modifying, and searching events through conversation. Its Google Calendar example explains that events synchronize with the calendar account and that deleting an event there removes it from the messaging view. The homepage leads with WhatsApp access; the feature page also names iMessage and WeChat. Confirm the currently offered route when joining.

Try this first message: ‘Add a 45-minute bike repair appointment to my Personal calendar on October 14, 2026, at 4 p.m. America/Toronto. Location: 18 King Street. Remind me two hours before. Tell me the saved date, time, and calendar.’ Then ask to move that same appointment forward by 30 minutes. Look for one updated event, rather than two separate appointments.

Poke and Caddy: when the appointment starts in email

Poke documents scheduling, availability checks, and reminders alongside email assistance. Its channels include Apple Messages, Telegram, WhatsApp, and RCS. Caddy documents iMessage on iPhone and RCS on Android. Its standard morning brief combines connected Gmail and Google Calendar context, and the briefing time can be changed or the brief disabled.

For either product, make the initial request easy to audit: ‘Find the latest confirmation for my bike repair. Tell me the date, location, and source email before adding anything.’ If the result is correct, ask to create the event in a named calendar. This separates finding the right message from making the calendar change, which helps identify where a mistake happened.

A brief is most useful when it changes your next action. Ask for appointments needing preparation, travel time you must allow, and unresolved clashes. A long chronological restatement of your calendar may save less effort than a short list of decisions.

Ohai: evaluate the handoff between family members

Ohai accepts texts and can extract scheduling details from emails, PDFs, and photos. That makes it a candidate when information arrives as school attachments or activity schedules.

Use a single school notice as the first trial: ‘List every date in this notice, distinguish attendance times from payment deadlines, and ask which child each item applies to.’ Review the extraction before saving the events. A deadline belongs in a task or reminder if nobody needs to block that time on a calendar.

Then check the receiving person's view. If one adult creates an event and another handles pickup, both need the same location and latest time. Agreement inside your own assistant conversation is not enough to establish that everyone has the update.

A useful five-minute calendar trial

Before relying on an AI reminder assistant, run this short sequence using an ordinary personal event. These are proposed evaluation steps, not claims that every product supports each operation.

Keep the product if corrections take less work than opening the calendar yourself and the saved result is consistently clear. If setup is the obstacle, narrow the trial to one account. If dates are the obstacle, provide explicit dates and time zones before expanding to recurring events.

• Create an event with an explicit date, duration, location, calendar, and time zone; inspect it in the calendar app.
• Change the time and confirm the original event was updated rather than duplicated.
• Ask about a conflicting event and see whether the assistant identifies the actual overlap.
• Set a near-term reminder and confirm where the notification arrives.
• Cancel the test event and its reminder, then verify that neither remains active.
