Signal Recorder
Voice recorder for Mac and iPhone. Transcripts and summaries run on your device. Every recording exports as a markdown file — yours, on disk.
Design Philosophy
A pristine workflow that feels almost analog.
The tools we use to capture shape how we think. A different pen changes the way you write; a recorder changes what you notice. In an age of AI, revisiting the proven practice of simply recording your thoughts turns out to be more relevant than ever.
Signal Recorder SR-7 gives you a quiet space to capture ideas, conversations, and observations, then turns them into something you can search, skim, and build on. Everything runs on your device. When you're ready, iCloud sync brings your library across Mac and iPhone, and the MCP server opens your archive to AI tools. On your terms, not theirs.
On-Device Transcription
Powered by the Apple Speech framework, SR-7 transcribes audio at high speed entirely on your device. Support for multiple languages. No network connection required, no cloud processing, no waiting.
AI Titles & Summaries
FoundationModels on macOS 26+ generates descriptive titles and concise summaries locally on your hardware. Every recording becomes searchable and skimmable — no cloud AI required.
MCP Server
On macOS, connect any MCP-compatible AI tool to your archive. Search by topic, pull summaries, extract quotes — locally, on your terms.
macOS only
Markdown Export
Auto-export recordings as Markdown files with YAML front matter. Integrates naturally with Obsidian, PKM systems, and any Markdown-based workflow.
iCloud Sync
CloudKit keeps your recordings, transcriptions, and metadata synchronized across all your Apple devices. Pick up wherever you left off.
Full-Text Search
Names, AI-generated titles, summaries, and full transcripts — all indexed. Find the moment you said it three weeks ago.
No accounts. No telemetry. No subscription.
Works with your hardware
Works with the TP-7 and any audio recorder

Questions
Yes. Transcription and the AI titles and summaries run entirely on your device. No network connection is required and nothing is uploaded.
No. You buy SR-7 once and it is yours — no accounts, no telemetry, no recurring fee.
On your device — nothing is sent to our servers. Sync is optional: iCloud keeps your recordings across your Apple devices, and on macOS you can mirror your transcripts to a read-only folder to read them as markdown files with YAML front matter.
macOS 26 or iOS 26. The on-device AI features need Apple Silicon (M1 or later).
Yes. On macOS, SR-7 runs a local MCP server, so any MCP-compatible AI tool can search your archive, pull summaries, and extract quotes — locally, on your machine. And because your transcripts can sync to a read-only folder as markdown, any AI tool with local file access can read them too.
