I've been thinking about why some AI learning tools become daily habits while others get tried once and forgotten. My current hypothesis: Instant start. No setup wall, so you can try it in seconds. Gentle feedback. Corrections that explain, not judge. Context over content. Explanations shaped to the learner's level and question. Something to keep. Notes, lists or exports so progress doesn't vanish. For those who use AI to learn (languages, coding, anything), what made you keep using a tool?
