What Loci does
Write, learn, and think things through
Turn a rough thought into a draft, explore a new subject, or work through an idea. Local AI gives you room to ask follow-up questions without uploading the conversation.
Ask about your documents
On iPhone and iPad, add a PDF, Word file, or EPUB and ask questions about its contents. The reading happens on your device, helping you work through material you already have.
Bring in current information
Use online sources when your question needs information from the web. These requests go directly to third-party providers, according to your source setting or when you ask.
How online sources work ↗What makes Loci different
Local conversations stay local
Your device processes local chats and stores their history. Loci does not use your conversations to train AI models. Explore private AI ↗
$0 subscriptions. No message caps.
Loci is free to download and use, with no ads or subscription to unlock. Ask another question, rewrite another paragraph, or keep exploring without a message allowance.
Useful in airplane mode
Download a model while connected, then keep chatting without internet. On a flight, during an outage, or beyond cellular coverage, the model runs on the hardware with you. Explore offline AI ↗
Local AI in your pocket
Loci brings local AI to iPhone, iPad, and Android as well as Mac and Windows. Use it on your phone, tablet, or computer.
A model that fits your device
Loci selects models for your hardware, so you can start without learning memory requirements or model file formats. On iPhone, you can also link to Loci on your Mac or PC to use larger models running on your computer.
Who uses Loci
Loci is for people who want a personal AI assistant close at hand:

- Sustainability-minded individuals who prefer to run AI on hardware they already own, without sending each local question to a data center.
- Anyone who believes AI should be for everyone — ad-free and unlimited, not just for people who can pay for a subscription.
- Independent founders and freelancers thinking through plans and drafting work they want to keep on their device.
- Writers and marketers shaping early ideas, exploring angles, and revising unfinished copy.
- Students and self-directed learners asking follow-up questions and working through reading material.

Frequently asked questions
Is Loci really free?
Yes. Loci has no subscription, ads, or message cap. The model runs on your own device.
Can I use Loci without internet?
Yes, once you have downloaded a compatible model. Typed chat works offline; downloading models, retrieving web sources, and using Windows online voice input require a connection.
Does anything leave my device?
Local chats and attached files are processed on-device. Online sources can send query text directly to third parties, and enabled diagnostic sharing sends technical information designed to exclude conversation content. The privacy policy describes these data flows in detail. Read the privacy policy ↗
Which AI models does Loci run?
Loci runs models from families such as Gemma, Qwen, Llama, and Phi. The app helps you find options suited to your device.
