Retext processes natural language through a plugin based toolkit in the unified JavaScript ecosystem.
About Retext
Retext is a tool that transforms natural language with plugins in the unified JavaScript ecosystem. It represents prose as concrete syntax trees that plugins can inspect and change, for tasks such as checking spelling, fixing typography, flagging redundant phrases, and checking readability. Users can use existing plugins or write their own.
The repository is a monorepo with parsers for English, Dutch, and other Latin-script prose, plus a serializer and a programmatic interface. It can run on the server, the client, Deno, and related JavaScript environments. The source recommends retext-english for English, retext-dutch for Dutch, and the general parser for other Latin-script languages.
