Instead of reminders it would be great to have timed prompts. Most LLM models are strictly request-response, the model does not take initiative to start an interaction.
What if you could, eg in the rabbit hole, define a prompt and the date/time it should be set off.
For example: for 7AM on weekdays: “start a conversation with a joyful moring greeting, tell me the weather forecast for today and give a summary of any major events that happened since 11PM yesterday”.
Simple reminders would also work by defining a prompt on how you want to be reminded.
Of course, using prompts triggering LAM, timed prompts would enable time triggered automations.
