About this extension
Reply Better AI helps you improve your messages using AI models through OpenRouter. The extension provides multiple improvement types including Professional, Friendly, Customer Service, and Concise formats. Create custom prompts for personalized text improvements and use text snippets for quick text expansion.
🚀 What's New (v1.2.3):
• Dynamic OpenRouter model picker — search any of 500+ models inside the extension, with Popular / Free / All tabs, live pricing, and a free-only filter
• Smarter inline button — only shows on long-form message composers, not on every search bar or form field
• API key moved to local storage — credentials no longer roam between browser profiles
• Friendlier errors — clear messages for invalid keys, unavailable models, rate limits, and offline state
• New full-tab settings page in addition to the toolbar popup
• Bug fix: the "model unavailable" banner now clears automatically when you pick a new one
✨ Features:
