Free AI that
runs on
your device

Bring me a question, a rough idea, or something you’re trying to work out. I can help you write, brainstorm, understand a tricky subject, code, or make a plan.

Go further with your own documents, meeting notes, dictation, and optional web search—all with local AI at the heart of it.

Search the web, chat with documents, turn meetings into useful notes, and dictate your ideas. Loci recommends a model for your hardware, and Loci Link lets your phone use the AI on your computer.

Your local work stays on your device. Web search uses online sources, and Link securely connects the devices you choose.

The biggest difference is where the intelligence lives: on the device you already own. Your local conversations stay with you, and a downloaded model keeps working without a connection.

Local chat is free, with no account, ads, subscription, or message cap. Choose a model that fits your hardware, and make it your own.

Yes. Download a model while you’re connected, and typed chat keeps working without a signal. On a flight, on a train, or somewhere you’d rather be offline.

Model downloads and online sources still need a connection. Voice input can also depend on your platform and settings, including online voice typing on Windows.

Local chat is processed and stored on your device. Loci doesn’t receive those conversations in ordinary use or use them to train models.

Online features have separate data flows. Web sources can send relevant query text directly to third-party providers. Optional diagnostics exclude conversation content, and diagnostic sharing is controlled in Settings.

Loci recommends the best fit for your device’s hardware, so you can start without comparing technical specifications or guessing what will run well.

You can explore other compatible models, too. Download one, then use it for private local chat—even without an internet connection.

You can get Loci on iPhone, iPad, Android, Mac, and Windows. Start with your device, choose a recommended model, and make yourself at home.

Model choices depend on your hardware, and some features differ by platform. You don’t need to create an account for local AI.

Yes. Local chat is free, with no subscription, ads, or message cap. The AI runs on the chip already in your device.

Download Loci, choose a model that suits your hardware, and keep the conversation going. No account needed.

Yes. When a question needs fresh information, Loci can look it up with online sources enabled. Ask about something happening now, or bring current information into what you’re working on.

Search queries go directly to third-party providers. Keep online sources off when you want to stay with local chat.

Add as many documents as you need to your library, then ask questions in plain language. Summarize a long report, compare ideas across files, or find the detail you’re looking for.

Your documents and the text Loci reads from them stay on your device during local chat. Bring your own knowledge into the conversation, privately.

Turn a meeting into notes you can use: the main points, decisions, and next steps. Ask follow-up questions to revisit a detail or pull out what matters to you.

Local transcription and summaries keep that work on your device, so the conversation stays private.

Speak an idea, a message, or a rough draft and turn it into text. Keep your train of thought, then ask Loci to help you shape the words.

Local dictation processes your speech on your device. Windows’ built-in voice typing is a separate option that may use Microsoft’s online speech service.

Yes. Bring a rough note, a first draft, or just what you want to say. In Loci, you can ask for help drafting an email, making a paragraph clearer, or finding a tone that sounds more like you.

You can keep refining it in the same conversation: shorter, warmer, or more direct. With a downloaded model, that writing can stay in local chat.

Pair your phone with Loci on your Mac or PC, then use a model running on that computer. Put your computer’s extra power to work from your phone.

Your requests and answers are encrypted between your paired devices. You choose the computer, and you can unlink it whenever you want.

Hi. Nice to meet you. I can tell you what Loci does, explain how private local chat works, or help you find the right starting point for your device.

I can walk you through what Loci can do, how offline chat works, which devices it supports, and what stays private. What would you like to know?
