Whet - Sharpen your mind - Sharpen your mind, 5 minutes at a time

by
Whet is a micro-learning app that creates 5-minute AI-powered lessons on any topic you’re curious about. What makes it different is that it doesn’t stop at content generation: Whet turns learning into a repeatable habit with interactive lessons, a personal knowledge graph, and spaced repetition built in. The result is a learning experience that is fast to start, personalized to you, and designed to help you remember what you learn.

Whet is designed to make learning feel as easy to start as opening TikTok, but much more intentional. You can pick any topic you’re curious about and get a 5-minute AI-powered lesson, personalized to your level. As you learn, Whet builds a visual knowledge graph of what you’ve explored and uses spaced repetition to help the important ideas stick. What started as an experiment in on-demand AI lessons became a bigger question for me: how do you turn curiosity into a habit, not just a moment? That’s the product I wanted to build. Would love feedback on the onboarding, lesson experience, knowledge graph, and whether this is something you’d actually use to learn a little every day.
