Checkpoint 6: Product Vision Report

Product Vision: Trax Media Processing Platform

1. Core Product Identity

What Trax Is

A deterministic, iterative media transcription platform that transforms raw audio/video into structured, enhanced, and searchable text content through progressive AI-powered processing.

Core Philosophy: "From raw media to perfect transcripts through clean, iterative enhancement"

What Trax Is NOT

  • A streaming service
  • A real-time transcription tool
  • A video editing platform
  • A content management system (though it integrates with one)
  • A social media platform

Core Value Proposition

  1. Accuracy First: 99%+ accuracy through iterative improvement
  2. Batch Native: Process hundreds of files efficiently
  3. Clean Iterations: v1→v2→v3→v4 without breaking changes
  4. Cost Efficient: Smart caching and optimization
  5. Developer Friendly: CLI-first, protocol-based, testable
