Private intelligence, without the relay
OnDevice LLM brings chat, vision, voice, and model control to iPhone — designed as a calm, capable glass surface for OnDevice LLM.
Chat with downloaded models, inspect code through Lens, speak without a cloud round-trip, and keep the whole loop visible. OnDevice LLM stays quiet so the work can be loud.
Fresh captures from the current OnDevice LLM workspace, set to Dark in the app. Tap any frame for a larger view.
Load, pause, and continue with a clear view of what is happening on-device.
Vision, OCR, and imported frames stay in the same local workflow.
Local speech tools with a library that feels like part of the studio.
Model families, memory fit, download state, and role — all in one surface.
Captured on iOS Simulator in Dark appearance. Lens reflects the simulator’s unavailable-camera state; no legacy captures are used.

VISION / OCRKeep dictation, transcription, and spoken replies in the same local loop.
SPEECH / TTSRun compact embedded intelligence inside the app experience, close to the task.
EMBEDDED / LOCALA launch-promo view of the surfaces, boundaries, and model runs that make OnDevice LLM useful.
