Private, on-device AI for Android
Your AI. Your device. Nothing else.
isolaite thinks entirely on your phone. Answers, document understanding, image recognition and dictation happen locally. Chats stay on-device; only model downloads and an explicit content-free safety flag use the network — no account, no subscription.

Privacy here is not a setting. It is the architecture.
In standard use there is no cloud service receiving your chats. isolaite ships neither analytics nor advertising SDKs, asks for no account, and after the one-time model download it works in airplane mode. Only a model download or your explicit content-free safety flag uses the network; the flag contains no conversation content. What follows is not a feature list so much as a description of what the app deliberately cannot do: it cannot read what you never hand it.
- Entry 01On-device inference
- Every answer is computed on your phone, by the model itself. After setup, flight mode changes nothing.
- Entry 02Sees only what you hand it
- isolaite never scans your storage, photos or messages. Nothing is ingested automatically — the only way in is you, attaching or importing it.
- Entry 03Understands documents
- Attach PDFs and text, then ask. What you hand the app is parsed and indexed in its private storage — and nowhere else.
- Entry 04Sees and listens
- Image understanding and dictation, computed by the model on your phone — not by a cloud speech service. Never stored, never transmitted.
- Entry 05State-of-the-art, entirely local
- A growing catalog of open-weight models for different devices and tasks — installed locally, switchable mid-chat and updated as the field moves.
- Entry 06News, offline
- A dated snapshot of the world arrives with every app update — read from disk, never fetched over the network.
- Entry 07No connectors
- No integrations, no add-ons, no analytics, and no background communication. The only app-originated network paths are user-started model downloads and an explicit content-free safety flag.
- Entry 08Paper and ink
- One light theme, two dark ones, four accent colours. Quiet enough for long reads.

State of the art, in your pocket.
isolaite gives you a growing catalog of open-weight models that run on your phone. Choose a quick text model or a more capable multimodal model, match it to your device and task, and switch inside the conversation. As better local models arrive, the catalog moves with them.
| Choose by | What isolaite shows you |
|---|---|
| Task | Text-only or multimodal, including image understanding and dictation. |
| Device fit | Download size, runtime and RAM guidance before installation. |
| Status | Active, inactive or downloading — visible directly in the model switcher. |
| Delivery | Installed on-device, integrity-checked, or imported fully offline as a file. |
The in-app catalog is the current source for model names, capabilities, sizes and device requirements.
“What you entrust to isolaite stays on your device — including every prompt and answer.” — the design principle
- Memory“Remember that …”
- Say it once, and isolaite has it ready in every new chat. Stored on this device only.
- RetrievalSemantic search
- The PDFs and notes you import are indexed locally — semantically and lexically — and drawn on while answering. You choose what goes in; nothing is added on its own.
- ErasureDelete means delete
- Uninstalling removes everything. No copy exists off-device; system backup is disabled.
Buy once. That's it.
No subscription · no in-app purchases

Answered briefly.
Does isolaite really need no internet?
Only for a model download during setup (or later when you add another model), or when you explicitly submit a content-free safety flag. All normal chats work fully offline. If you prefer, import the model as a file and never download one.
Where are my chats stored?
Exclusively in your device's private app storage. There is no chat sync and no system backup. An explicit safety flag sends only category, app version and model — never answer content.
Is there a subscription?
No. A one-time purchase of €9, with no further costs and no in-app purchases.
What happens to my voice during dictation?
The recording is transcribed on-device, never stored and never transmitted. The app asks explicitly before first use.
Does isolaite read the files on my phone?
No. It never scans your storage, photos or messages. It only sees what you actively attach or import into the app — and that stays in the app's private storage.
Are there connectors or integrations?
None, by design. No add-ons, no plug-ins, no third-party services that talk to the internet.
Which models does it run?
A growing catalog of open-weight models, always local. The app shows each model's capabilities, size, runtime and RAM guidance before installation, and the catalog evolves as stronger local models become practical on Android.
