Speak is a language learning app built around speaking out loud. Lessons written by language education experts and personalized by AI teach the phrases native speakers use, drill them until they are automatic, then let learners use them in open conversation with an AI tutor.

Key features:

Learn phrases and patterns for real situations such as making reservations instead of grammar drills.
Repeat patterns in new contexts until they feel natural.
Hold back-and-forth spoken conversations with the Speak Tutor.
Get feedback on the mistakes that matter and retry as often as needed.
Study Korean, Japanese, French, Spanish, Italian, English or Chinese, depending on native language.

Speak is a consumer app for iOS and Android aimed at adults who want conversational fluency, with more than 15 million downloads reported. Learners can start speaking for free before moving to a paid subscription.
