Pros

  • Learners who already have a beginner grammar path
  • People who want a free reference beyond Tae Kim
  • Readers who look up patterns from input

Cons

  • You are still learning kana
  • You need scheduled retrieval practice
  • A dense reference will stall you

Imabi is a large free grammar site. Lessons go from particles into constructions most beginner books never reach. It behaves like a reference shelf, not a 20-minute daily app.

Who it fits

Use it when a textbook note is too thin, or when you met a pattern in reading and need a fuller explanation. Intermediate learners get more from it than absolute beginners.

Limits

There is no review queue. Density can freeze a new learner. Pair it with Tae Kim as the first explanation source, or with Bunpro if the bottleneck is retrieval rather than explanation.
