isolaite: Private On-Device AI

isolaite is your personal AI assistant that keeps working in airplane mode. Buy once, use forever. No subscription, no account, no cloud inference.

Why isolaite?
• Airplane-mode ready: once a model is on the device, chats, documents, knowledge, and (with a capable model) image understanding and dictation work without a connection.
• Pay once, get everything: no subscriptions, no in-app purchases, no ads.
• Open-weight models in Settings: pick what fits your device, from a small text model to multimodal Gemma 4 packs with image understanding and dictation. Changing model is a Settings action and reloads the engine; it is not a mid-chat switch.
• Images on device: describe a picture in the composer and it renders locally. Packs are large (around 4 GB) and a run takes several minutes on a phone. The model card states size, RAM, and expected duration before you start.
• It sees only what you hand it: isolaite never scans your storage, photos or messages. You attach or import a file, or it stays out.
• No analytics, ads, tracking SDKs, or cloud assistants. You can share a generated picture through the system share sheet, and you can pick a file through the system picker.

Your knowledge stays yours
• Personal Knowledge: import PDFs and text, save notes and chat exports, then ask questions about them. Retrieval stays local.
• Memory: say "remember that…" and isolaite recalls it in later chats.
• News: a dated offline snapshot that arrives with app updates. It is not live internet. The snapshot date is always visible. Wikipedia text in the snapshot is CC BY-SA 4.0.

A premium experience
• Paper-and-ink design language with separate light and dark designs, a composer layout you choose, and selectable accents.
• Chats with pinned files and images, renamable.
• Answers stream on-device. Requires Android 16 or later.

Privacy by architecture
Normal use sends no chats or personal knowledge off your device. Internet is used to download a chosen model from its public repository and only when you explicitly submit a content-free safety flag (category, app version, model). Prompts, answers, documents, attachments, and chat history stay on the device. See https://isolaite.app/privacy.

Recommended hardware
Android 16 or later. Each model shows download size, capabilities, and RAM guidance before installation. Dictation and image understanding need a multimodal pack (Gemma 4), not the small starter.
