LocalMindAI - On-Device AI

An AI that runs only on your iPhone. Attach PDFs or photos in chat or add them to Documents, and it uses them to answer. Chats, memories and documents stay on the device.

LocalMindAI is an AI companion you can talk to every day, and everything it does happens on your iPhone. Your conversations, memories, photos and voice messages are processed on the device and are never sent to a server. No account or sign-in needed.

A COMPANION THAT REMEMBERS • Give your companion a name and a personality, and choose how it talks. • It remembers what you share (favorite things, plans, how your day went) and brings it up naturally later. • Review, edit or delete memories at any time in the Memory tab. • Continuous mode keeps one ongoing conversation and quietly summarizes older parts so it can keep up. Start a new topic whenever you like.

ANSWERS FROM YOUR DOCUMENTS (NEW) • Add PDFs, text files or photos under Memory > Documents, and the AI finds the relevant parts and refers to them when it replies. • Ask about manuals, handouts or notes you have on hand. Pick several photos at once to make one document. • Documents are stored only on your device and never sent anywhere. Reply Details shows which documents and pages were used.

PRIVATE BY DESIGN • All AI processing, including chat, memory, speech transcription and reading text in photos, runs on the device. • The network is used only to download the AI models you choose, show ads and check for the latest version. Your chats, memories and documents are never used for ads. • Works offline once your models are downloaded.

CHOOSE YOUR MODEL • On devices with Apple Intelligence, use Apple's built-in model with no download. • Or download open models such as Qwen3.5, Gemma 4, LFM2.5 and llm-jp, in sizes that fit your device. • Vision models understand the photos you attach, and thinking mode shows the model's reasoning on harder questions. • Experimental options include highly compressed models and models that run on the Neural Engine.

GENTLE AND SAFE • On-device safety checks decline harmful requests and stop unsafe replies. • If you're going through a hard time, it responds with care and shows local support resources. • Long-press any reply to report it.

MORE FEATURES • Voice messages transcribed on the device • Attach photos; text in images is read on the device • Conversation styles: Standard, Small talk and Just listen • 10 languages: English, Japanese, Chinese (Simplified and Traditional), Korean, Spanish, French, German, Portuguese and Italian • See how fast each reply was and how much of the conversation was reused

Optional tips help keep development going. Any tip turns off ads for good.
