OnDevice: Local AI Studio
Language & Visual & Voice
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Local-first AI on your iPhone: chat, ask about photos, talk and create with the models you choose. New: images the assistant creates now appear in your chat.
OnDevice is a local-first AI studio for iPhone. Run compatible language, vision, speech, and image models on your device. Browse models and choose what to download. Model size, memory use, and speed depend on your hardware.
CHAT AND CREATE
Ask questions, write, work with code, save snippets, and export conversations. Use camera or photo input with a compatible vision model, or use built-in OCR without downloading a vision model. Voice conversations use local Apple speech by default, with optional downloadable neural voices. Compatible image models support local image generation, which can be restricted with a parental PIN.
YOU CHOOSE THE CONNECTIONS
Local inference uses installed models. Network features are optional: model discovery and downloads, web search, paired Mac tools, a local API, and iCloud sync. Web providers may receive the queries or content you choose to send and may require their own API account. No app account is required for local use; there is no analytics SDK.
REQUIREMENTS
Requires iOS 18 or later. Downloadable models need storage and sufficient available memory. The app may pause or refuse heavy workloads when the device is too hot or memory is low. Model compatibility and performance vary by device.
Ratings & Reviews
• Images the assistant creates now appear in the chat once they are ready, even when the image model takes a while to load.
• While an image is being made, the chat shows its live progress.
• If you decline a web search or a file request, the assistant answers right away instead of asking for another tool.
• Fixed the app freezing and closing when opening Voice settings.
