Learn English, one small step at a time.

A roadmap from A1 to C1, practice in reading, listening, speaking, writing and language, and an optional TOEFL warm-up.

What you practice

Five skills, one roadmap.

  1. Reading

    Passages with multiple-choice questions.

  2. Listening

    Questions read aloud by your computer’s voice.

  3. Speaking

    Record your answer. With an OpenAI key it is transcribed; without one, you rate yourself.

  4. Writing

    Tasks with a word target and a rubric to check your work against.

  5. Language

    Grammar gap-fills and vocabulary, with example sentences.

How it works

Set up once, then follow the path.

danna starts from your goal, your daily time and where you feel comfortable. The roadmap and Today’s plan follow from those answers.

  1. 1

    Tell danna your goal

    Choose what you practice, how many minutes you have each day, and an exam date if you have one.

  2. 2

    Follow the roadmap

    Lessons go from A1 to C1. Each one earns up to three stars, and Today shows your next step.

  3. 3

    Review and ask

    Review with spaced repetition. With your own AI key, ask the coach anything, or ask about the files in your library.

Your data

Your progress stays on your computer.

  • No account needed

    Use danna on this device. Lessons, answers and progress are stored on your computer.

  • Your AI key stays encrypted

    Windows encrypts the key on your computer. Requests go straight from the app to the provider you chose: OpenAI, Anthropic, Google Gemini, OpenRouter or DeepSeek.

  • Accounts are optional

    An online account adds sync across devices and friends. It is never required.

Open source

Read the code. Build it yourself.

danna is released under the MIT License. The app, its lessons and every release live on GitHub, so you can read the code, report a bug or build the installer yourself.
