Typlx review
A free, privacy-focused checker for writers who want local processing and model choice.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Typlx is a free, open-source grammar checker for privacy-conscious writers and developers. It processes grammar locally by default, works offline, and does not require an account. Browser extensions are available for Chrome, Chromium-based browsers, and Firefox, while an iOS keyboard provides mobile access. Personal dictionaries and customizable grammar rules make it suitable for users who want more control than a fixed grammar checker provides.
Its main distinction is model flexibility. Typlx can connect with OpenAI, Anthropic Claude, Google Gemini, Ollama, LM Studio, and vLLM, covering both cloud services and locally hosted models. API tokens are stored in encrypted local storage. Users who already operate a local model server can keep checking workflows close to their own environment, while users who prefer hosted models can configure a supported provider. Self-hosting and the MIT License also fit developers who want to inspect, adapt, or deploy the software themselves.
The published Free plan costs $0, is free to install, and includes open-source distribution with no account required. Local grammar processing, offline checking, a personal dictionary, customizable rules, browser extensions, and the iOS keyboard support a privacy-first workflow without a subscription tier. The trade-off is that configurable AI workflows require provider setup, particularly when connecting cloud services or local servers. Android is not listed among the available platforms. Typlx suits users who value local control, extensibility, and model choice; those seeking a broader mobile footprint or a more fully managed setup may prefer a different checker.
