What's New in Catalyst
1.4
September 8, 2026
Long replies keep going when you leave Lock your phone or switch apps mid-reply and Catalyst picks the conversation back up when you return, showing the finished answer or reconnecting to the one still in progress. No more "the reply never started" when it had. Get notified when a reply is ready For a long answer, image, or video, tap "Notify me" and Catalyst sends a notification the moment it finishes. Tap it to jump straight into that chat. You choose when to allow notifications, and you can change it anytime in Settings. Siri and Shortcuts Say "Ask Catalyst" to send a question, "Voice chat with Catalyst" to start talking hands-free, or "Compare models in Catalyst" to put one question to every model you've pinned. Every phrase works as a Shortcut and on the Action Button. Find, rename, and delete chats Search your chats from the sessions drawer, rename any of them, and swipe to delete the ones you're done with. Also in this release • Your chats appear in Spotlight, and Handoff lets you continue one on another device. • Voice mode replies now play at full volume through the speaker. • When a model fails in a multi-model comparison, its tab shows the error instead of a blank reply. • Subtle haptics when a message sends and voice mode starts.
