◇ Could this help me?
Yes. The two underlying patterns are sound: a local Obsidian vault as a personal knowledge base keeps data on your own machine, and Kokoro is a legitimate, widely used open-weights text-to-speech model that genuinely replaces paid TTS API costs for personal voice interfaces. This is a project-specific personal-infrastructure pattern, not a Claude Code update, and the video shows rather than teaches it, so treat it as inspiration; any Kokoro install must follow research-first, approval-gated framing.
Research the Kokoro open-weights text-to-speech model before any installation: identify the official model repository and publisher, its license, how it is typically run locally, what hardware it needs, and whether it is safe and reputable as a free local alternative to paid text-to-speech APIs such as ElevenLabs. Present those findings for review and do not install anything until it is explicitly approved. Separately, outline how a local Obsidian vault could collect AI conversation notes and research into linked nodes as a personal knowledge base, listing the options from simplest (manual notes) to most automated, with the tradeoffs of each.
