Call Annie is a language-learning app built around video calls with AI avatar tutors, covering English, Spanish, French, German, Japanese, Mandarin and Korean. The format is the point: speaking is the skill most learners avoid practising, because it needs another person and carries the risk of embarrassment.
Putting it on a video call rather than in a text box forces the part that actually transfers, and an avatar that is available at any hour removes the scheduling problem that makes conversation practice the first thing to lapse.
There is a free tier, and a developer API for building on top of it. The product has moved here from general conversational AI, pricing beyond the free tier is not detailed on the homepage, and an avatar still will not catch nuance the way a fluent human teacher does.
