Correctly review
A focused, privacy-oriented browser checker with flexible local and provider options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Correctly is an open-source browser extension for checking grammar, spelling, and punctuation directly in text inputs, textareas, and contentEditable elements. It is designed for people who want writing assistance inside Chrome or Firefox while retaining control over how AI processing is handled. Suggestions appear inline, with explanations that help users understand each proposed correction. Corrections can be accepted or dismissed, and checking can be disabled on specific sites.
Its strongest distinction is the range of processing choices. Correctly supports local and on-device models, including Ollama, LM Studio, and Chrome's built-in Gemini Nano, while also connecting to OpenAI and OpenAI-compatible providers. The listed integrations include OpenAI, Groq, OpenRouter, DeepSeek, Ollama, LM Studio, and Chrome Free AI. Custom model selection adds control for users who want to choose a particular provider or model rather than rely on a fixed service.
Privacy controls make the extension a fit for sensitive browser-based writing. Correctly offers automatic exclusion of sensitive fields and per-site opt-outs, alongside local inference options. The trade-off is focus: the product is centered on browser text fields and lists one supported language, so it is less suitable for multilingual writing or users seeking a broader desktop, document, or team writing platform. Correctly is a strong choice for privacy-focused Chrome users who value open-source software and configurable AI routing; users who want a ready-made hosted service or wider language coverage should choose an alternative.
