Yes. Loci is free to download and use on Android, iPhone, iPad, Mac, and Windows. There are no subscriptions, no ads, and nothing to unlock.

Does Loci work without internet?

Yes. Download a model once over Wi-Fi and typed chat keeps working with no connection at all — in airplane mode, abroad, or in dead zones. Model downloads, optional web search, and Windows online voice input need a connection when you use them.

Are my conversations private?

Yes. Chat is processed on your device and is not uploaded. There is no account, no server-side copy of your conversations, and no training on your words.

Which AI models does Loci run?

Loci will automatically size the best model for your hardware but you'll be able to download different ones, including Gemma, Qwen, Llama, and Phi.

Free with no ads — what's the catch?

There isn't one. Loci runs open-source models on the chip already in your device, so there are no server bills to pass on to you. We don't sell ads, and we can't see your conversations — they never reach us. We built Loci because we think capable AI should be a public good.

Describe this image

The image depicts a warm, indoor scene on a wooden table. To the left sits a vibrant blue ceramic mug, and beside it is an open notebook with clean pages, suggesting readiness for writing or planning. Centered behind the notebook is a potted tropical plant with large, lush green leaves in a terracotta pot, adding a touch of life to the setting. To the right side of the table, there are a pile of chunky, mustard-yellow knitted scarves and a pair of round spectacles resting near the open book, suggesting a cozy, contemplative moment indoors. Sunlight streams through a window visible in the background, illuminating the objects on the wood surface.
