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.
- Reading
Passages with multiple-choice questions.
- Listening
Questions read aloud by your computer’s voice.
- Speaking
Record your answer. With an OpenAI key it is transcribed; without one, you rate yourself.
- Writing
Tasks with a word target and a rubric to check your work against.
- 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
Tell danna your goal
Choose what you practice, how many minutes you have each day, and an exam date if you have one.

2
Follow the roadmap
Lessons go from A1 to C1. Each one earns up to three stars, and Today shows your next step.

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.
