Voxa

Voxa lets you call into your laptop from a phone browser, talk to a Gemini Live "operator," and have it drive Claude Code by voice.

MVP scope (drive mode only): pick a working directory by voice, send spoken instructions, hear Claude's final result read back. Attach mode, voice folder-browsing, and barge-in interruption are V2 backlog items (see docs/superpowers/specs/2026-06-27-loop-design.md and docs/superpowers/plans/2026-06-27-loop-mvp.md).

Prerequisites

• Python 3.11+ on the laptop.
• Tailscale installed and logged in on both the laptop and the phone (free personal plan is fine). The phone must be on the same tailnet as the laptop, or MagicDNS must be enabled.
• A Gemini API key from Google AI Studio with Gemini Live access.
• Claude Code logged in on the laptop (claude CLI authenticated). The agent SDK reuses your existing Claude Code credentials; no separate ANTHROPIC_API_KEY is needed unless you prefer to supply one.

Quickstart

Install Voxa on the laptop you want to control with one command.

macOS / Linux:

curl -fsSL https://voxa.space/install.sh | sh

Windows (PowerShell):

irm https://voxa.space/install.ps1 | iex

Prefer a package runner? These work on any OS:

npx voxa-code            # Node users
uvx voxa-code            # Python users (or: pipx install voxa-code)

Then start it:

voxa

Voxa is zero-config by default: it uses the hosted relay, so there are no API keys to set up. voxa starts the server and prints a pairing QR code. Scan it with the Voxa phone app (or open the printed URL in your phone browser) to connect.

Develop from source

Contributors who want to hack on Voxa can run it from a checkout instead of the published package.

1. Create and activate the virtual environment

python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"

2. Configure secrets

cp .env.example .env

Open .env and fill in:

GEMINI_LIVE_MODEL, VOXA_HOST, and VOXA_PORT have sensible defaults and can be left as-is.

3. Start the server

bash scripts/serve.sh

The script:

1. Starts the Voxa FastAPI server on 127.0.0.1:8787 (or $VOXA_PORT).
2. Calls tailscale serve to expose it over HTTPS on your tailnet (required because the phone browser needs a secure context for microphone access).
3. Prints the full HTTPS URL including your auth token.

4. Connect from the phone

Open the printed URL on your phone browser. Tap Connect, then speak.

Architecture (brief)

Phone browser (static/)
    |  HTTPS WebSocket (auth token required)
    v
FastAPI server (server/app.py)
    |  audio bytes (16 kHz PCM)
    v
GeminiOperator (server/gemini_operator.py)  <-->  Gemini Live API
    |  tool calls (start_claude_session, send_to_claude, …)
    v
Orchestrator (server/orchestrator.py)
    |
    v
ClaudeController (server/claude_controller.py)  -->  Claude Code (agent SDK, bypassPermissions)

Config is loaded from .env via server/config.py.

Running the test suite

.venv/bin/python -m pytest -v

Expected: 22 tests pass, no warnings.

Manual end-to-end smoke test

The smoke test requires a real phone, real Tailscale connectivity, and real API keys. Run it against a scratch directory, not a real project.

Before you start:

• .env is fully filled in (real GEMINI_API_KEY and VOXA_AUTH_TOKEN).
• Tailscale is running on both the laptop and the phone.
• Claude Code is logged in on the laptop.

Procedure:

1. Open a terminal on the laptop and run:

   bash scripts/serve.sh
   

   Wait for the line Voxa is live. On your phone open: https://...

2. Copy the printed HTTPS URL (it already includes ?token=...).

3. On the phone, open the URL in Safari or Chrome. You should see the Voxa interface. Grant microphone permission when prompted.

4. Tap Connect. The button should change state to indicate an active session.

5. Speak: "Start a session in /tmp/loop-smoke and create a file called hello.txt that says hi."

6. Verify:

   • Gemini acknowledges the instruction verbally (you hear a response through the phone speaker).
   • On the laptop terminal you see Claude Code start with bypassPermissions active (no permission prompts appear).
   • After Claude finishes, /tmp/loop-smoke/hello.txt exists on the laptop and contains hi.
   • Gemini speaks the final result back to you.

7. To stop: press Ctrl-C in the laptop terminal. The trap in serve.sh will kill the server and tear down tailscale serve.

Warning: Use a throwaway scratch directory (like /tmp/loop-smoke) for your first smoke test. Claude Code runs with bypassPermissions, so it will write files without asking.
