Not a crippled demo
Use OSS for real work—and for pre-purchase validation.
The free edition contains the core desktop and developer workflows. Pro is a focused upgrade for people who want richer voice, automation, persistence, and management.
LLM Converse
Streaming spoken conversations with any compatible endpoint, multiple profiles, sentence-level TTS, session headers, and failure detection.
Developer bridge
Synthesis, transcription, JSON capability discovery, streaming PCM, cancellation, a warm daemon, and integration installers.
Naming made explicit
Product name: AverVOX. Package and command: avrvx.
Version 0.5.5 also adds the fully spelled alias so users can install or launch the product using the name they heard.

Interaction modes
Three hotkeys, plus a composable CLI.
Use only the parts you need. Dictation and selected-text speech do not require an LLM endpoint.
Dictate
Ctrl+Alt+Space
Speak into the focused application.
Read aloud
Ctrl+Alt+S
Hear the current text selection through Piper.
Converse
Ctrl+Alt+C
Hold a streaming spoken LLM conversation.
Automate

Use local speech in scripts and host applications.
OSS versus Pro
Upgrade for experience—not basic access.
The same core architecture and integration contract remain in place when Pro is installed.

OSS questions
Start in public. Keep control of the decision.
Why is the installer recommended over pip?
The repository installer also handles Linux system packages, the isolated environment, Piper voice model, desktop menu entry, autostart, and launcher. A bare pip install still requires the documented system dependencies, and on Ubuntu 24.04, Debian 12+, and Linux Mint 22 it fails outright with pip's externally-managed-environment error unless you use pipx or your own virtual environment.
Can OSS be used commercially?
The repository is published under the MIT License. Review the license file for the governing terms; the Pro license separately covers the commercial proprietary edition.
Where should OSS issues be reported?
Use the GitHub issue tracker for reproducible OSS problems, feature requests, and integration discussions. Licensed Pro customers may also use email support for product issues.
Is the OSS edition a trial that expires?
No. It is a separate open-source edition with no time limit. Pro is an optional one-time purchase that adds the documented premium features.
Can I contribute another integration?
Yes. The public integrations repository documents the bridge and existing host packages. A good integration should use capability discovery, preserve cancellation, prefer the warm daemon, and fall back safely.
