Description

AI-powered grammar and writing assistant Grmmr is an AI-powered grammar and writing assistant for Chrome and Firefox that helps you craft clearer, more polished text anywhere on the web. It supports automatic or manual checking with a compact suggestion card that shows type, original text, corrected text, and a brief explanation, and lets you apply or dismiss changes individually or all at once. Configure your provider (OpenAI, Anthropic, or a custom endpoint), API key and model. It’s designed for reliability and performance, defensively parses LLM JSON, and masks sensitive information in logs, giving you fast, privacy-conscious grammar help wherever you write.
