Signal Recorder SR-7
On-device voice recorder that transcribes and exports Markdown.
What it does
• Records high-fidelity audio with live visual waveforms and native pause-and-resume capabilities. • Transcribes speech to text completely on-device using the Apple Speech framework without network dependencies. • Generates local AI titles and summaries using Apple Silicon FoundationModels. • Exports recordings automatically as Markdown files with YAML frontmatter for Obsidian and Git workflows. • Exposes a built-in local MCP server allowing AI coding agents to query your voice archive securely.
Why it works
Zero cloud dependency ensures absolute user data privacy and removes server-side processing bottlenecks. Buy-once pricing model with no subscription appeals to users fatigued by recurring monthly software fees. Native local MCP integration allows AI coding tools like Claude Code to interact directly with local voice note archives. Automatic Markdown file generation fits effortlessly into existing text-based knowledge management systems.

Frustrated that most voice tools trap transcripts in closed servers or apps, he built a local-first utility designed to keep thoughts entirely on device while feeding directly into modern Markdown and AI workflows.
