WHAT LOCAL AI ASSISTANT DOES

A focused private chat that runs on your computer

Type a message and watch the reply stream in from a model on your own device — with clean session history and simple context controls, and nothing else in the way.

Private and on-device

With the local model, the AI runs on your machine — your messages aren't uploaded, there's no cloud account and no per-message bill. Turn the network off and it keeps working. No account is needed to use the free tier.

Type and stream

Pick a model, type a message, and the reply streams in as it's written — so you're never waiting on a blank screen. Stop a reply mid-stream whenever you've seen enough.

Many separate sessions

Keep as many conversations as you like, each its own saved chat in a clean, flat list — rename, pin and delete. Every session keeps its own context.

Find & search

Find a phrase within the current chat, or search across all of your chats and jump straight to a match — so an earlier answer is always easy to get back to.

Simple context controls

Tune each conversation with two controls that are always one click away — a creativity (temperature) dial from precise to exploratory, and a maximum reply length. Set them per chat or as your defaults.

Encrypted history

Sessions and messages are saved encrypted at rest on your device, and telemetry is opt-in and content-free — never your prompts, messages or any personal data.

Move & export your chats

Back up and restore your conversations to move them between machines, or export a single chat as Markdown. There's also a headless CLI for power users and scripting.

Choose your model

A free on-device model ships out of the box, auto-selected to suit your device on first launch — so there's no setup. The catalog updates itself, and Pro unlocks larger local models and cloud providers when you want extra power.

In your language

The whole interface is available in 16 languages and follows your operating system's language automatically, with a one-click switch in Settings.

SEE IT IN ACTION

A clean chat, your model, your machine

A familiar chat with the essentials and nothing else: streaming replies, your own choice of on-device model, simple per-chat controls, and encrypted history.

HOW IT WORKS

Your first private chat in under a minute

1. Open the app

A free on-device model is auto-selected to suit your device and downloads once on first launch, then runs offline — no account and no setup.

2. Type and chat

Send a message and the reply streams in. Tune the creativity and reply length per chat, and start a new conversation whenever you like — each one is saved on its own.

3. Keep it, find it, move it

Every chat is saved encrypted on your device. Search across all of them, export one as Markdown, or back up and restore to move them between machines.

WHO IT'S FOR

For anyone who wants AI chat to stay private

When your conversations are sensitive or simply yours to keep, Local AI Assistant brings the AI to your messages instead of sending your messages to the cloud.

Privacy-conscious

For anyone who wants their AI chats to stay on their own machine. The AI runs locally and history is encrypted at rest — nothing is uploaded.

Regulated industries

Legal, healthcare, finance and public-sector teams where prompts and replies can't leave managed hardware — the conversation stays on the device with the local model.

Offline & air-gapped

Fully usable with no network once a model is downloaded — a fit for disconnected and air-gapped environments.

No usage fees

Capable AI without a per-message cloud bill. Chat as much as you like on the free on-device model, and keep working offline.

Available on Windows today

Get Local AI Assistant now from the Microsoft Store on Windows, with a headless CLI for power users and automation. Editions for macOS, Linux, the browser and mobile (Android and iOS) are planned.

PLANS

Every feature is free. Pro is about choice of model.

Free gives you the complete app — many sessions, find & search, the context controls, encrypted history, backup & restore and the CLI — on a capable on-device model, with no time limit or nag screens. Pro simply unlocks larger, more capable local models and optional cloud providers; the tier gates only the model, so no feature is ever locked away.

Students, educators, researchers, non-profits and other qualified users can apply for a free 12-month Pro licence.
