As of 13 August 2026, AI can check when meeting attendees are available.
This still needs a person who signs their name to it.

What the alternative costsA human assistant can compare shared calendars and confirm with attendees; no price is supplied in the available tool data.
If this goes wrong, you propose a slot that conflicts with an attendee's private commitment and need to reschedule.
What to actually do
Hand it to a person
The route this page recommends
A person who owns the outcome does this end to end, worth it when the failure is dear.
Do it yourself
Second choiceA chat interface, chat-fluent skill, and roughly 15 minutes until you can act on the result.
How to actually do it
- Open the calendars you are authorised to view and note the meeting date range, duration, UK time zone and required attendees.
- Gather each attendee's visible busy, free, tentative and out-of-office entries, together with any working-hour or no-meeting preferences.
- Paste the meeting details and the calendar extracts into the prompt, labelling missing, private or unclear entries instead of treating them as free.
- Ask the chatbot to return a table of suitable slots, showing availability for every required attendee and separating optional attendees.
- Compare the suggested slots against the current calendar entries you can see, including recent changes and tentative bookings.
- Send the shortlisted slot or slots to the attendees who have private or unshared calendars and ask them to confirm before you offer a final time.
Prompt
Check when these meeting attendees are available. Meeting date range: [PASTE DATES] Meeting duration: [PASTE DURATION] Time zone: UK time unless stated otherwise Required attendees: [PASTE NAMES OR LABELS] Optional attendees: [PASTE NAMES OR LABELS] Working hours and preferences: [PASTE ANY LIMITS, SUCH AS NO EARLY MORNINGS] Availability data or calendar extracts: [PASTE THE DATA HERE] Use only the availability data I provide. Do not claim that someone is available if their calendar data is missing, private, tentative or unclear. Treat busy, out-of-office and unconfirmed entries as unavailable unless the data explicitly says otherwise. Identify the earliest suitable slots, show which attendees are available for each slot, flag any assumptions, and state which attendees still need to confirm. Do not contact anyone or book the meeting.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

The distant third
What it gets wrong
- AI cannot see a calendar that you have not connected or whose details you cannot provide.
- AI cannot know whether a visible free period is genuinely usable when an attendee has a private commitment or an unrecorded obligation.
- AI cannot infer company meeting rules, travel time or personal preferences that are absent from the calendar data.
- AI cannot obtain consent or confirmation from attendees without you contacting them.
- AI can compare the supplied information, but you still carry the responsibility for proposing the slot.
Even on a YES, the friction has a name: private data access, verification cost and context depth.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.
| Axis | Score (0–2) |
|---|---|
| Output | 2 |
| Inputs | 1 |
| Verification | 1 |
| Liability | 2 |
| Effort delta | 2 |
| Total | 8 / 10 |

FAQ
- Can ChatGPT check everyone's availability?
- Only if you give it the relevant calendar data or use a connected calendar service with permission to read those calendars. It cannot verify private or missing commitments, so the attendees still need to confirm the proposed slot.
- Can AI find a time that works for everyone?
- Yes, when the calendars, time zones, duration and working preferences are complete. It should present possible overlaps rather than assume that an unclear or private period is free.
- Is it safe to let AI access work calendars?
- Use only a service approved by your employer and grant the narrowest access that supports the task. Check what calendar information the service stores and do not paste sensitive meeting titles when free and busy information is enough.
- Can AI book a meeting after checking availability?
- Some calendar products can continue from availability checking to scheduling, but that is a separate action with its own permissions and risks. Check the final attendee list, time zone and slot yourself before anything is sent or booked.
