• Run powerful local models like Llama, Gemma, Phi, Qwen, DeepSeek, and more
• Store models where you want: internal storage, an external drive, or a shared volume
• Analyze sensitive PDFs and documents safely offline
• Use local, offline speech recognition and text-to-speech
• Connect to cloud providers only when you need to
TALK, TRANSCRIBE, AND LISTEN
Turn speech into text instantly, then have answers read back when you would rather listen.
• Use Voice Typing on Mac and the voice keyboard on iPhone and iPad
• Choose from Apple Speech, Whisper, Parakeet, Nemotron, Qwen3-ASR, and more
• Record and transcribe meetings, lectures, interviews, and voice memos

• Export transcripts as text, subtitles, or Markdown
AI CHAT THAT FITS YOUR WORKFLOW
Work with local or cloud models, attach your own content, and stay in control of every conversation.
• Drag documents and images into a chat, or paste them in
• Read past conversations instantly without loading a model first
• Fork a conversation from any message without losing the original
• Copy or export complete threads
• Select several conversations to delete or add to a Knowledge Library at once
• Get more room to type when the keyboard is open on iPhone or iPad
• Switch models, tools, and roles as your task changes
BUILD YOUR OWN KNOWLEDGE LIBRARY
Turn documents, notes, conversations, and transcripts into private, searchable context for your AI.
• Add PDFs, text files, Markdown, code, images, and website content
• Drag files straight into your library
• Write and edit Markdown notes without leaving the app
• Import AI chats, voice notes, or text-to-speech items
• Search and filter large libraries quickly
• Adjust retrieval settings per library when you need more control
• Re-index edited content so results stay current
WEB RESEARCH, TOOLS, AND AGENTS
Give your AI what it needs for research and multi-step work.
• Search the web from inside a conversation
• Let the browser agent open pages, read sites, and gather information
• Pause the browser, adjust the task, or take over manually
• Use tools for calculations, network requests, and document analysis
• Build specialist agents for writing, coding, analysis, and planning
• Run subagents and bring their results back into one conversation
BUILT FOR APPLE DEVICES
• Start requests or open saved content with Siri, Apple Shortcuts, and App Intents
• Reach common actions from the Mac menu bar and customizable keyboard shortcuts
• Use On-Device AI on iPhone, iPad, Mac, and Vision Pro

Robust Framework, Except need for Experience Improvement
Redhat_man
So far it’s been a very good catalogue of integrated models, and recent add of the DeepSeek variants is even more appealing. Few areas of improvement, especially in saving chats or for the system to automatically save each chat session or have user save them and be able to return to them in future. Currently it is quite annoying to loose chats that have started, only to start rebuilding the whole context again. Also providing a means to base saves chats to specific Models will be a very good. Can’t wait to see or experience the next update. So far so good, but missing features elaborated make it. A tertiary app compared to others i use as a default. Perhaps these updates when done could change that.
Developer Response
Thank you for your support and suggestions! That’s really valuable feedback. I’ll try to work on improving the chat experience in future updates. Please continue to support us!
Best local AI on iPhone
beats1393
I honestly can’t fathom how this app is free. It’s like stumbling upon a treasure chest in a sea of paid apps that don’t even offer a fraction of these features. The fact that you can run AI models locally, with this much precision and functionality, is mind-blowing. Meanwhile, so many “premium” apps charge a hefty price for far less.Now, about the negative reviews—let’s address the elephant in the room. If your 6GB iPhone can’t handle an 8B model, that’s not the app’s fault; it’s basic tech knowledge. Calling the app a “scam” because of hardware limitations is akin to blaming a sports car for not fitting in a bicycle lane. Let’s be real: you wouldn’t try to cram a piano into a shoebox, so why attempt to run a high-performance model on a device not equipped for it?This app is a gem, and any criticism rooted in misunderstanding is just noise. It’s evident that the developers behind this masterpiece know their stuff, and the fact that it’s accessible to everyone at no cost deserves applause. If you’re into cutting-edge AI and have the right hardware, this app is a game-changer. Don’t sleep on it!
Upgrading my review to 5 stars...

UPDATE: The Developer's prompt response below took care of the problem after I unplugged my iPad from the charging brick, while running the app, my device no longer overheated. I really like this app and appreciate the rapid response support. Having access to LLMs offline (when wi-fi connectivity isn't available) is a much appreciated gift. Thanks🙏🏼 ............................. ORIGINAL REVIEW: How can I use this app on my ipad pro (12.9" m1 fifth gen 16mb device with 1TB memory) but without it overheating my device??? For example, I just ran a simple search and analysis of cutlery "super-steels" and my device screen promptly heated up to the touch. No other apps I have used elicit this speedy and high a temperature increase. I am concerned that continuing to use it will damage my iPad. Developer, please discuss and identify how to fix this problem. Please note that I downloaded only one of the two LLMs recommended by the app for this iPad's capabilities.
Developer Response
Thank you for your feedback! Since the AI models run locally on your device for privacy, intensive processing does generate heat, especially during long tasks. This is particularly noticeable when your device is connected to power during use.Immediate suggestions:1) Disconnect from power cable during AI processing when possible2) Take breaks between longer tasks to let device cool downI'm going to adding a thread control setting that will let you adjust processing threads. Lower thread count = less heat but slower processing. Higher thread count = faster but more heat. You'll be able to choose the balance that works for your needs.Thanks for helping make the app better!
Shortcuts compatibility is awesome!
MemeMaster's Play
The ability to make a shortcut that allows for running an LLM in the background is great. Do you believe that there are any extra features you can add for shortcut compatibility? For example: - Defining a system prompt - Continuing a conversation - Defining a preset conversation (to be used as synthetic context) then generating a response to the defined conversation ... all in Shortcuts :D There are just a few problems, however. I've come to find that a message may just stop generating out of the blue, and that in Shortcuts, generated responses from the same query are always the same. Aside from these minor issues, thank you so much for implementing this feature, I can see many practical shortcut workflows coming up in the near future, and maybe you could even put together a community of Shortcut users where they show off cool little applets and masterpieces through the power of prompt engineering!
Version 1.46.0 adds Calendar and Reminders tools, a faster Text Note workspace, stronger AI Search, and more Shortcuts support.
• Calendar and Reminders tools: With your permission, AI tools can read, create, update, complete, move, and delete events or reminders after you review changes.
• Text Note workspace: Create a note quickly, pick the Knowledge Library it belongs to, edit in a cleaner notes view, and keep it searchable.
• Cleaner AI Search context: Web results now skip consent pages, cookie notices, search-engine boilerplate, and other unusable pages, with fallback behavior when a result set is noisy.
• Save AI Search results: Import a completed AI Search answer into a Knowledge Library as a curated Markdown snapshot with the query, answer, sources, and supporting context.
• Smarter note destinations: When you use multiple Knowledge Libraries, the app asks where a new note should go instead of creating duplicate default libraries.
• Customizable side menu: Choose which sections stay pinned in the sidebar and open everything else from the new Menu.
• More Shortcuts actions: Transcribe audio files, speak text, export generated audio, and create Text Notes from Apple Shortcuts or Siri.
• Better TTS playback: Kokoro long-form playback now keeps generated segments tied to the active session, so restarts and cleanup behave more reliably.
• Safer Calendar & Reminders permissions: Actions require explicit permission, personal-data consent, and a review step before changes are applied.
• Fixes and improvements: Improved Text Note selection, autosave/status feedback, keyboard behavior, and sidebar navigation.
