How It Works

Three Steps to Your App

From idea to running application in under a minute. No coding experience required.

01

Speak or Type Your Idea

Describe what you want in plain words. "A calculator with dark mode" or "a todo list app" — just tell CodeTalk your vision.

02

AI Plans & Writes Code

The on-device AI plans the project, creates all files, handles dependencies, and writes production-quality code automatically.

03

Build, Install & Run

CodeTalk compiles and builds your app right on your phone. For Android apps, it creates a real APK you can install and share.

Privacy First

Your Code Stays on Your Device

CodeTalk is built with privacy as a core principle. No cloud dependency means complete control over your data.

🔐

Local AI Processing

All inference runs on your device's CPU/GPU. Zero data sent to external servers.

📡

No Data Collection

We don't collect analytics, telemetry, or usage data. Your projects are yours alone.

✅

Works Offline

After one-time model download, CodeTalk works without any internet connection.

Roadmap

What's Coming Next

We're constantly improving CodeTalk. Here's what we're working on and what's planned.

Planned

Code Diff Mode

Instead of regenerating full files, the AI will output patches for incremental changes — reducing hallucination on large files.

Planned

In-App Web Preview

Render web projects in an embedded WebView tab instead of launching Chrome, keeping you inside CodeTalk.

Planned

File Diff Viewer

See before/after diffs when the agent modifies existing files, so you always know exactly what changed.

Planned

Parallel File Generation

Generate independent files concurrently instead of sequentially, saving a full inference round on multi-file projects.

Planned

Cloud + Local Hybrid

Use a cloud LLM for planning and local model for code generation — combining the best of both worlds.

Planned

One-Tap Deploy

Deploy web projects to GitHub Pages or Netlify with a single tap, sharing your creation with the world.

Shipped

Undo Agent Changes

Files backed up before each write. One-tap undo restores all backups instantly.

Shipped

Export as ZIP

Package your entire project as a ZIP file, ready to download and share.
