Privacy by architecture

Your data never has to leave your device.

Localyze.ai was designed privacy-first, not privacy-as-a-marketing-line. Inference, memory, voice, and image processing all run locally on your hardware.

100% on-device inference

Gemma 3n E4B runs natively on your CPU, GPU, or NPU.

No telemetry, no ads

No mixpanel, no segment, no fingerprinting. Period.

No account required

No email, no phone number. Install and chat in 30 seconds.

You own your data

Export anytime; one-tap delete for everything stored.

What it does

A real AI assistant — without the cloud.

Powered by Google's open Gemma 3n E4B model running natively on your hardware.

Conversational chat

Saved conversations, pin, rename, search. All local.

Voice input

Hold to talk. Audio is transcribed on-device — never uploaded.

Image understanding

Share a screenshot or photo. Read locally, answered locally.

Opt-in memory

Off by default. Turn on, view, edit, or wipe anytime.

Privacy center

Every byte you've stored, in one screen. Delete in one tap.

Native, per platform

Kotlin on Android and Qt6 on Ubuntu — out now. WinUI, SwiftUI/MLX, iOS — coming soon.

How it works

Three steps to a fully private assistant.

No sign-up. No cloud configuration. No API keys.

1

Install the app

Google Play, or the native installer for Windows, macOS, or Linux. Under 30 MB.

2

Download the model

One-time ~4 GB Gemma 3n E4B fetch from Hugging Face. After that, fully offline.

3

Chat — with anything

Text, voice, images, files. Pin, search, export. Wipe it all in one tap.

vs. the cloud assistants

Built differently. On purpose.

Architecturally private — not because we promise to be careful, but because your data never reaches us.
