LocalMind

Your text→your device→your answer.

No middlemen. No copies on someone else's servers. No "we use your data to improve our models".

How it works

Everything happens inside your computer

Chrome ships with its own AI model, Gemini Nano. LocalMind uses it directly, so your questions never travel to a server.

Your device

Step 1

You type or share

A question, a PDF, a spreadsheet or the page you are reading.

Step 2

LocalMind prepares it

It extracts the text in your browser. Long documents are read in parts.

Step 3

Gemini Nano answers

Chrome's model generates the answer on your own hardware.

Your data stays here, stored only in your browser

Blocked

The internet and the cloud

LocalMind does not send your conversations, documents or pages to any server. Not ours, not anyone else's.

Work

A practical guide to remote work: habits that actually work

Working from home offers flexibility, but it also blurs the line between personal and professional life.

The first habit is to set fixed hours and share them with your team.

Documents

Analyze your documents without uploading them anywhere

Drop in a PDF, Word, Excel or PowerPoint file. LocalMind reads it in your browser and gives you the summary, the key figures and the risks.

100% private. No fine print.

This is not a marketing promise: LocalMind is built so that your data cannot leave your device.

On-device AI

Gemini Nano runs inside Chrome, on your own hardware. Nobody else sees your questions.

No network requests

LocalMind does not connect to any server. The only download is the model, which Chrome fetches the first time.

No accounts

No sign-up, no login, no email. Install it and start.

No tracking

No analytics, no telemetry and no ads. We don't know what you do, and we don't want to.

AES-256 encryption

Password-protected spaces. The key is derived with PBKDF2 and the password is never stored.

One-click deletion

Settings → Data deletion. And if you uninstall the extension, everything goes with it.

Don't trust us: check it yourself

Turn off your Wi-Fi after the model's first download: LocalMind keeps answering.
Open LocalMind, right-click → Inspect → Network tab: you won't see a single request to any server.

Requirements

Will it work on my computer?

Since the AI runs locally, your computer needs some power. These are Chrome's requirements for Gemini Nano.

Chrome 138 or later

Windows 10/11, macOS 13+, Linux or ChromeOS (Chromebook Plus).

22 GB free to download it

Chrome asks for this space on your profile's drive to fetch the model, which then takes up much less.

Capable GPU or CPU

A GPU with more than 4 GB of VRAM, or 16 GB of RAM and 4 cores.

A single download

You only need internet for Chrome to download the model the first time.

Frequently asked questions

Is nothing really sent to the internet?

Really. LocalMind has no servers and makes no network requests: text, documents and pages are processed with Gemini Nano inside Chrome, on your device. The only thing downloaded is the model itself, and Chrome downloads it the first time.

What is Gemini Nano?

It is the AI model Google builds into Chrome so it can run directly on the device. LocalMind uses it through the browser's Prompt API.

Do I need an account?

No. Not for LocalMind or any other service. Install the extension and start using it.

Where are my conversations stored?

In your browser's local storage. If you create a password-protected space, they are stored encrypted with AES-256. You can delete them whenever you want from Settings → Data deletion.

What if I forget my space's password?

It cannot be recovered, precisely because it is never stored anywhere. The conversations in that space stay encrypted for good.

How much space does the model take up?

Much less than 22 GB. Chrome asks for 22 GB of free space on your profile's drive so it can download it, but the model itself is considerably smaller and its exact size changes with updates; you can check it at chrome://on-device-internals. If free space later drops below 10 GB, Chrome removes the model and downloads it again once there is room.

Does it work offline?

Yes. Once Chrome has downloaded the model, LocalMind works without internet.

How much does it cost?

Nothing. LocalMind is free and has no paid plans.

Which languages does it support?

The interface is available in English and Spanish, and you can switch in Settings. Translator mode translates between the two.
