SageVox

SageVox is an interactive AI audiobook application for iOS. The GitHub repository was created in January 2026. The premise is real-time voice interaction with an AI agent while listening to an audiobook, with the constraint that the AI cannot spoil future content.

Concept

The README description: "Interactive AI audiobooks. Ask questions about your book without spoilers." The key mechanic is the no-spoiler constraint: the AI agent answers questions about the book up to the listener's current position, but not beyond. This requires the agent to track reading position and limit its responses accordingly.

Technical Stack

The profile README specifies the implementation: FastAPI (Python backend), LiveKit (real-time audio infrastructure), Gemini TTS (text-to-speech), and SwiftUI (iOS frontend). The stack crosses three languages (Python, Swift) and uses two external AI services (Gemini for voice synthesis, and implicitly another model for the conversational agent).

LiveKit is a real-time communication platform used for voice streaming. Its presence signals that SageVox handles live audio rather than pre-rendered audio responses.

Status

SageVox is listed as legacy work in the profile README. The repository is public. No App Store listing is linked.

Relationship to Outgoing Agent

Both SageVox and Outgoing Agent are classified as legacy AI agent projects. SageVox is the more technically complex: it involves real-time audio, constraint-aware responses, and iOS native development. The two projects mark the period when AI agentic patterns entered Mike's product work.
