Security-first AI · why it matters

Build mobile apps,
keep your secrets.

The AI mobile-dev agent that never ships your credentials, .env or source code to a model. Memory, mind-map & a self-testing loop, built in.

Security-first by design

Other AI tools leak. Bryt is built not to.

Most coding assistants happily slurp your whole repo — secrets and all — into a remote model. Bryt was designed from day one to make that impossible.

Credentials never exposed

API keys, tokens and passwords are detected and stripped — they never enter a prompt, a log, or a third-party model.

.env stays invisible

Bryt deliberately ignores your environment files. Secrets in .env are never read into context, ever.

Encryption on credentials

Anything sensitive Bryt does store is encrypted locally on your machine — not sitting in plaintext.

No source-code exposure

Bryt reasons over your project's structure and graph — not your raw source dumped to an external API. Your code stays yours.

Built to be affordable

Frontier output.
A fraction of the cost.

Bryt-F1 ships the same production-ready screens, architecture and tests as the big models — at a price low enough to build all day. Up to 20× cheaper than Claude, and priced below even today's most affordable models.

Not another chat box. A real agent.

We built the things other tools skip — memory, structure and a self-correcting test loop — so Bryt actually understands your app.

Persistent Memory

Bryt remembers your project, decisions and conventions across sessions — so it builds the way you build, not from scratch each time.

Mind Map

A live map of your app's logic and dependencies. Bryt understands how pieces connect, not just isolated files.

Screen Graph

Every screen and navigation path, mapped. Bryt reasons about real user flow before it writes a line of UI.

Testing Loop

Generates, runs and fixes tests in a closed loop — iterating until the code actually passes, not just compiles.

Credential Encryption

Keys and secrets are encrypted locally and kept out of every model call. Security isn't a setting — it's the default.

No Source-Code Exposure

Bryt works from structure and graphs, so your proprietary source never leaves your machine for a third party.

Four frameworks.
One honest start.

Our goal is to cover the four frameworks that matter for mobile — Android, iOS, Flutter and React Native.

We're early and we won't pretend otherwise: we've started with Flutter, and even that is just the beginning. It's a long road — and we're building it in the open.

Flutter
Dart
In progress

Where we started — premium UI, architecture & tests. Still early.

Android
Kotlin · Java
Coming

Native Android with Jetpack Compose and classic views.

iOS
Swift · Objective-C
Coming

SwiftUI and UIKit, the Apple way.

React Native
TypeScript
Coming

Cross-platform JS/TS, one codebase.

From idea to app — safely.

01
Connect securely

Sign in with Google. Bryt indexes your project's structure — never your secrets or raw source.

02
Describe & build

Ask in plain words. Bryt uses memory, mind map and screen graph to build the right thing.

03
Test & ship

The testing loop runs and fixes its own code until it passes — then you ship it.
