Grammar checker status overview
This page provides an overview of grammar checkers for different languages. These tools are built from the language models in the lang-* repositories.
The grammar checkers are grouped according to maturity. Private repositories are not listed.
The maturity levels are production, beta, alpha and experimental. Some beta grammar checkers are used in practical applications.
Being in the Production group means the grammar checker has been tested and is considered stable enough for production use.
Automatic classification
Grammar checkers are automatically classified based on version number and number of error detection rules:
- Production: version ≥ 1.0.0
- Beta: version < 1.0.0 and rule count > 10
- Alpha: version < 1.0.0 and rule count 5–10
- Experimental: version < 1.0.0 and rule count < 5
- Undefined: missing version or lemma count data
This objective classification ensures transparency and gives language teams clear upgrade criteria.
