SparkAI Language Learning vs Duolingo for French
Both can help you learn French, in different ways. Duolingo turns practice into a game you can play in a few minutes. SparkAI is a structured course that explains the grammar, makes you read a lot, and goes all the way to C2. Here's an honest look at both, written by SparkAI's maker, so read it with that in mind.

| Maturity | Over a decade old, used by millions, with professionally produced content. | A new product in public beta, made by one developer; content written with AI assistance and being reviewed by a native speaker. |
Where Duolingo is stronger
- Habit and fun. Its streaks, leagues and quick lessons are very good at getting people to open the app every day.
- Polish and platforms. Mature iOS and Android apps with professionally produced audio and illustrations.
- Breadth. Dozens of languages in one app, a huge community, and years of testing on millions of learners.
- Proven track record. SparkAI is new; its content is still being reviewed and it will have rough edges.
Where SparkAI is stronger
- Grammar you understand. Every topic has a full explanation, and mistakes show you the rule, not just the right answer.
- It goes further. Lessons continue through B2, C1 and C2 (the subjunctive, passé simple, registers, advanced connectors).
- Real reading. Stories and complete classic books, with a reader that tracks the words you know.
- Serious vocabulary practice. Thousands of flashcards with FSRS spaced repetition, the scheduler used by dedicated flashcard learners.
- Free without limits on studying. No energy system and no ads during the beta; the AI conversation partner is included.

A sample lesson: Être (to be) – present tense
The start of SparkAI's lesson on être, exactly as it appears in the course.
Être (to be) is the most important verb in French. It's irregular, so you need to learn each form by heart.
