What Correctly is

Correctly is a free, open-source browser extension that checks grammar, spelling, and punctuation as users write. It works in text inputs, textareas, and contentEditable elements, showing each proposed correction in an inline tooltip that users can accept or dismiss. The extension supports English and provides packages for Chrome/Chromium and Firefox; its landing page also names Edge, Brave, and Opera as Chrome-compatible options. AI choices include OpenAI, compatible APIs, Ollama, LM Studio, and Chrome's built-in Gemini Nano. Ollama and LM Studio can run checks locally, while Chrome Free AI uses on-device Gemini Nano. For OpenAI or compatible endpoints, users supply their own API key and select a model in the extension popup. Correctly has no cloud service or account: text is processed locally or sent directly to the configured provider. Keys are stored in browser extension storage and sent only to that provider. Sensitive fields such as passwords and credit card inputs are excluded automatically. With providers other than Chrome Free AI, text is sent to the selected provider for checking.
