What arrives on demand

dictionary
Hunspell dictionary with full affix morphology and compounding
frequency
No Kelly list under this code; ranking leans on the dictionary and model
semantic
FastText ONNX embedding model for context-aware reranking — available as fluency (~15 MB, the default), full (120 MB), or mini (~3 MB), chosen at setup
keyboard
Keyboard proximity on the Czech-QWERTZ layout

Automatic detection is included — a document in this language is found before it is checked.

Set it up

gem install kotoshu
kotoshu setup cs

# optional, for semantic reranking
gem install onnxruntime
kotoshu setup cs --model                  # fluency, the default (~15 MB)
kotoshu setup cs --model --tier full      # maximum accuracy (~120 MB)

Notes

  1. 1.

    Keyboard-proximity suggestions use the Czech-QWERTZ grid — z and y swapped, with háčky and čárky as dead keys.

  2. 2.

    The fastText ONNX model fasttext.cs.onnx is available for semantic reranking of suggestions.

  3. 3.

    Czech ships a single base dictionary; no regional variants are staged yet.

  4. 4.

    No Kelly frequency list is published for Czech yet; frequency data is an optional resource, so checking works without it.
