AI and machine learning, used honestly

An AI language tutor, built on machine learning

FluentSprout uses AI where it helps you learn, and machine learning where it helps you hear, speak and understand. Here is exactly where, and what each part can and cannot do.

Where we use AI

AI tutor and conversation partner

Explains, corrects and adapts to your level, and talks with you on 20 everyday topics, by voice or text.

AI feedback on writing and speaking

Exam-style writing and speaking tasks get AI feedback against the criteria the exams publish, with an improved version. Practice estimates, not official scores.

AI-generated listening

Listening exercises written by AI at your level, read aloud by neural voices.

AI-written lessons, checked automatically

Lessons are written with AI and checked automatically for accuracy. Spot a mistake? Report it from any lesson step.

AI course builder

Make your own private course for any language, dialect or topic with ChatGPT, then FluentSprout turns it into lessons with practice and tests.

Bring your own AI

Add your own ChatGPT, Gemini or Claude key to make fun, story or travel versions of any lesson.

Where we use machine learning

Speech recognition

Machine-learning speech recognition (Amazon Transcribe) shows which words it heard when you speak, so you can check your pronunciation.

Natural AI voices

Lessons, examples and translations are read aloud by neural text-to-speech voices (Amazon Polly and Google Chirp 3 HD), in the accent you choose.

Translation

Machine-learning translation for text, photos of signs and menus, and speech (Amazon Translate, Textract and Transcribe).

What is not AI

Smart review brings words back just before you would forget them. It uses spaced repetition, a well-studied scheduling method, not machine learning.

The limits

AI can make mistakes. Check anything important, and report anything that looks wrong.
Speech recognition shows which words it understood. It is not a pronunciation or accent score, and it is not an examiner.
Levels and scores in the app are practice estimates. Only the exam bodies issue official results.
