Reminder Bot (KindlyRemindly)

KindlyRemindly, which appears in Telegram as Reminder Bot, reads reminders the way you would say them. Type "call the dentist tomorrow at 10" or send a voice note, and the bot transcribes it, works out what and when, and creates the reminder. Schedules go beyond "every day": weekly, monthly and yearly repeats, every N days and date ranges are all supported, and each reminder can carry its own time zone, which helps when family or colleagues live in different countries.

Two features set it apart from the plain reminder bots in this list. A countdown reminder sends a short daily message counting down the days to a date, for an exam, a trip or a deadline. And the bot works in groups, supergroups and forum topics, where a shared reminder notifies everyone in the chat and administrators decide who may create reminders. Everything is listed in a Mini App, where reminders are paused, resumed, edited or deleted.

The site remindly.you says the bot is completely free, with voice reminders, complex schedules, multiple time zones and the Mini App included. The interface is available in English, Russian and Brazilian Portuguese. It is a young project from a small developer, with no public usage figures yet.
