Yes. Vox is 100% free and open source under the MIT license. No subscription, no usage limits, no hidden costs.

Does Vox work offline?

Yes. After the initial model download, Vox runs entirely on your Mac with no internet connection required.

Vox runs locally on your hardware. Your conversations, files, and data never leave your device. No cloud, no telemetry.

What can Vox do that ChatGPT cannot?

Vox controls your desktop — it manages files, sends emails, replies to iMessages, captures screen regions, and runs background agents. It works offline and keeps all data on your device.

Does Vox work on Windows or Linux?

Vox is Mac-first today. The core architecture is platform-agnostic, and Windows and Linux support is the top contributor priority.

Index Your Codebase and Search It by Voice

Vox's knowledge base isn't just for PDFs and documents — it can index your entire codebase. Every function, every config file, every README becomes searchable by voice. Here's how to set it up for development workflows.

Add your project folder

Go to the Knowledge tab and add your project directory:

Vox — Indexing Codebase

✓Scanning ~/Projects/my-app — found 1,247 filesDone

✓Filtering: .js, .ts, .py, .json, .md, .yaml...Done

✓Chunking: 1,400 chars per chunk, 200-char overlapDone

✓Indexing with 4 parallel workersDone

✓Indexed 1,247 files — codebase searchableDone

Search your code by voice

“Computer, where is the authentication middleware defined?”

Search Results

Found in 3 files:

src/middleware/auth.js (lines 12-45)

exports function authMiddleware that validates JWT tokens...

src/routes/index.js (line 8)

imports and applies authMiddleware to /api routes...

tests/auth.test.js (lines 5-89)

Test suite for authentication middleware...

Ask questions about your code

Don't just search — have a conversation about your codebase:

“Computer, how does the payment flow work in this project?”

“Computer, what environment variables does this app need?”

“Computer, are there any TODO comments in the codebase?”

“Computer, explain what the webhook handler does.”

Tip

Vox uses the FTS5 index to find relevant code, then uses AI to explain and summarize it. It's like having a senior developer who read every line of your codebase available on voice command.

Supported file types

Code File Types

JavaScript: .js, .jsx, .mjs, .cjs

TypeScript: .ts, .tsx

Python: .py, .pyw

Ruby: .rb, .erb

Go: .go

Rust: .rs

Auto-reconcile for active development

Vox re-scans indexed folders every 10 minutes. As you write code, new files and changes are automatically picked up. No manual re-indexing.

Note

All code indexing happens locally. Your source code stays on your machine in a local SQLite database. Nothing is uploaded to any cloud service.

Index once, search forever. Your codebase becomes a conversational knowledge base that you can query by voice while writing code.

Vox vs GitHub Copilot: Desktop Agent vs Code Assistant

Copilot writes code in your editor. Vox manages everything else — files, email, research, documentation. They are complementary.
