Geoffrey Litt’s “Stevens” is a surprisingly effective AI assistant built with minimal tech – essentially a single SQLite database and cron jobs – that delivers a personalized daily brief to its user via Telegram. Stevens pulls data from various sources like Google Calendar, weather APIs, and Telegram conversations to provide calendar events, reminders, and even fun facts. Unlike larger, commercially driven assistants, Stevens is tailored to the user's specific needs and offers a degree of control and customization, highlighting the potential of simple, user-focused AI solutions.
