What's new in 1.3.0

• Fresh new look with a cleaner design and automatic dark mode. • Rewrites now stream in live, so you watch the result appear as it's written. • New Changes view highlights exactly what was edited, word by word. • Regenerate cycles through alternative versions until one fits. • The inline ✍️ button now opens a review panel: pick a style, preview the result with its changes, then insert it. Prefer one click? Switch it to instant rewrite in settings. • Redesigned model picker and a rebuilt full-page settings screen.

🚀 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: • Inline improvement button on long-form text composers across the web • Multiple message styles • Custom AI prompts • Text snippets for quick responses • Local storage for privacy • Works with free and paid AI models on OpenRouter

Is Reply Better AI Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Reply Better AI requires a few sensitive permissions. Exercise caution before installing.
