What's New in On‑Device AI

1.49.0

September 15, 2026

Version 1.49.0 is for the work that starts with a long recording, a scanned document, or an idea you want to hear out loud. It also makes a growing app much easier to find your way around. • Recording a meeting, class, interview, or research session? MOSS Transcribe + Diarize is our recommended model for meeting notes. It separates speakers and now uses less memory, so long recordings can finish more reliably. Your original audio stays untouched. • Add a scanned report, paper, receipt, contract, or class handout to AI Chat and ask questions about it. If a PDF has no readable text, the app asks before running OCR on your device. You can follow progress page by page or cancel without leaving a half-finished attachment. • Supertonic, VoxCPM2 Int8, VoxCPM2 BF16, and IndexTTS2 are new in this release. Depending on the model and your device, you can make narration for a presentation, create a voiceover, listen back to your own writing, or use a saved reference voice. • The Menu now keeps the workspaces you use most under Pinned, with everything else under Available. Settings are grouped by purpose and adapt to the screen, whether you are on an iPhone or working with a sidebar on a larger device. • Agent Workflows are easier to set up. Start with an Agent Profile for a repeatable job, such as research or editing, then add the AI Skills, MCP servers, and tools it needs. On Mac, messaging app connections now have their own Settings area. • The Model Library is now the main place to browse, download, choose, repair, or remove chat, transcription, speech, and embedding models. Speech downloads also show clearer progress, including quiet stretches during large transfers. • Saved chats open correctly on the first try. Long answers scroll more smoothly, and you can begin reading before rich formatting is done. • Cloud requests have more time to respond. If one fails, the app stops cleanly, keeps any partial reply, and leaves a successfully loaded model ready for another try. • We also cleaned up the AI Chat model header and Voice Note controls. Conversation Mode returns to listening after it speaks, and deleting an active chat no longer lets old work bring it back.

Great app! Great dev!

Dev is very responsive! Constantly improving!

still full of bugs

the voice mode is still mot working right, the interface is horribly bad design, it crashes every 5 minutes etc... no response from the developer... skip this! there are many AI client apps out there that actually work.

incredibly capable

Well done!

Importing your own models is amazing!

I love the ability to add your own mlx or gguf models!

crash crash crash

an other update with hopes crushed by constant crashes, voice mode crashes when you use the auto mode after the first answer, it does not switch into listening mode, just simply crashes no matter what voice model or ai model you use... on an M2 ipad pro with 16 gigs of ram... this app was never stable, pretty much unusable, no response from developer... don't spend money on this app, not worth it until they fix the bugs instead of packing more and more features into it.

Response from developer

Hi trancemuter, thank you for using the app. We apologize for the inconvenience. It was a bug that has now been fixed in the latest version. You should be able to long-press and copy the model response in iOS, and select text on macOS. Please update to the newest version to try it out.
