## Description

**On-Device AI: Private Workspace** combines private AI chat, voice tools, research, document listening, and notes in one native app for iPhone, iPad, Mac, and Apple Vision Pro. Download local models from families including Gemma, Qwen, DeepSeek, and Mistral, then work offline with your chats, documents, recordings, and notes kept on your device.

Transcribe meetings, dictate notes, listen to PDFs and web articles, search your private knowledge library, follow RSS feeds, and use an AI browser agent for research. Optional cloud providers and web features are available only when enabled. The app also supports OCR, text-to-speech, Markdown notes, model management, Apple Shortcuts, Siri, widgets, and customizable workflows with tools, skills, and MCP servers.

## Review summary

Users praise On-Device AI for its broad, powerful feature set, offline/local operation, and support for many models and multi-agent workflows, plus strong web search and cross-device use. The app is seen as easy to set up and generally fast, with good privacy thanks to on-device processing. However, recurring complaints point to stability issues (crashes with large models or contexts, boot-time crashes) and persistent UI/UX drawbacks (scattered settings, lack of a manual). Functionality gaps repeatedly noted include exporting whole chats, inconsistent search behavior, and limits in client/local-server integration. Some users also question pricing transparency and battery/thermal impact on devices.

### Pros

- Extensive feature set with a wide range of models and flexible offline/local operation, including support for running large models via Mac LM Studio.
- Built-in web search and deep information retrieval within chats.
- Multi-agent / character support enabling creative, role-playing conversations.
- Strong privacy and cross-device experience thanks to on-device processing and syncing across iPhone, iPad, Mac, and Vision Pro.
- Easy setup and generally fast performance with a polished UI that improves over time.

### Cons

- Stability issues: crashes when sending prompts, with large contexts or large models, and occasional boot-time crashes.
- Clunky UI/UX with settings scattered, lack of a manual, and learning curve.
- Feature gaps: cannot export an entire chat, inconsistent or slow web search, and limited client/local-server integration (localhost/IP issues).
- High resource usage on devices, leading to battery drain and overheating in some devices like iPad.
- Pricing transparency concerns and some fees for advanced features, plus complaints about paid audio transcriptions and overall pricing policy.
