What Typlx is

Typlx is an open-source grammar checker that the maker describes as privacy-first. Grammar checking happens locally and works offline, and users can add names, technical terms, acronyms, and domain-specific words to a personal dictionary. Individual grammar rules can be switched on or off. Typlx offers Chrome and Firefox extensions; its Chromium extension is also described as working with Brave, Edge, Arc, and other Chromium-based browsers. An iOS keyboard app is available, while the Android keyboard app is in progress. When a user requests a correction through an LLM endpoint they configure, selected text is sent to that endpoint, which can be OpenAI, Anthropic, or a local model such as Ollama or LM Studio. Settings and encrypted API tokens are stored locally, and Typlx says it does not operate its own servers or cloud backend. Analytics are not collected unless users opt in. The software is free, requires no account, and is released under the MIT License.
