## Description

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, model, auto-check, and debounce timing from the popup, and quickly verify connectivity with a built-in test. Grmmr uses a bold dark UI with clear yellow accents, a subtle badge (✓ for auto, ⚡ for manual), efficient debounced checks to reduce reflows
