Official Product & Architecture Page (OneMira C1 — $99 One-Time, $0/Month Forever): https://onemira.com/products/c1

This technical note presents the system architecture and 3-year Total Cost of Ownership (TCO) analysis of OneMira C1 by OneMira AI, a standalone AI voice recorder and compounding local context system built on Google's Native Open Knowledge Format (OKF) and the Model Context Protocol (MCP).

1. Core System Architecture & The 4 Validated Buyer Pillars

• ✨ Local AI ($0/Month Forever): Generates structured meeting summaries, decisions, mind maps, and action items using OneMira Desktop's built-in Local LLM on macOS and Windows — or connects to user-controlled model services via API keys (OpenAI, Anthropic Claude, Google Gemini, DeepSeek, local Ollama). Eliminates the $179–$240/year cloud subscription paywall after 300 minutes/month found in conventional recorders.
• Works Standalone: Single-press hardware capture with a silent physical rotating turntable indicator. Captures in-person meetings, lectures, and voice notes independently without cables or active mobile apps, syncing automatically later.
• 🗣️ Speaker ID + Earphone & AirPods Call Capture (Bot-Free): Automatically separates speakers across in-person rooms and online calls. Unlike magnetic phone-back pads that cannot capture digital audio routed to AirPods or headphones, OneMira Desktop records dual-channel system audio + microphone on Zoom, Google Meet, Microsoft Teams, Slack Huddles, and WhatsApp without injecting a recording bot into the participant list.
• Zero Cloud Lock-In + Native MCP & Obsidian Wiki: Stores transcripts locally as deterministic Open Knowledge Format (OKF) Markdown (.md) with YAML frontmatter and stereo .wav audio. Exposes a native Model Context Protocol (MCP) server and CLI for Claude Desktop, Cursor, ChatGPT, and Obsidian.
