What Safetyper is

Safetyper is a free, open-source browser extension that provides AI-assisted grammar, spelling, and punctuation corrections while you type. It is available for Chrome and Firefox and is described as working on any website, including Gmail, Slack, and Notion. The extension detects text inputs, highlights edits inline, caches intelligently, and adjusts its icon position to fit pages. You can supply your own OpenRouter or Groq API key, or connect Ollama to run models locally. The maker says Ollama keeps text on your machine without API calls or cloud processing, while OpenRouter and Groq credentials remain on your device rather than Safetyper servers. The project uses the Apache 2.0 license, and the maker says its projects have no features behind paywalls. A usage-based subscription is planned, but no price is listed. Registration collects an email address stored on encrypted EU servers with access controls. Support is directed through the coolLabs Discord.

Who it suits

Safetyper fits Chrome or Firefox users who want inline writing corrections across many websites. It also suits users who prefer supplying their own AI key or running models locally with Ollama.
