Design Philosophy

Built for thinkers

A pristine workflow that feels almost analog. And that is by design.

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.

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.

01 — Audio Capture

Never miss a moment

High-fidelity audio recording with pause and resume. A physics-based reel-to-reel visualisation and live waveform don't distract but immerse and reassure that nothing is lost.

02 — On-Device Transcription

Words from sound, instantly

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.

03 — AI Titles & Summaries

Find the thread in every recording

FoundationModels on macOS 26+ generates descriptive titles and concise summaries locally on your hardware. Every recording becomes searchable and skimmable — no cloud AI required.

04 — Project Organization

Structure that matches how you think

Group recordings into projects. Drag-and-drop reordering keeps your library structured the way your mind works. Star important recordings for quick access.

05 — Full-Text Search

Find any moment, instantly

Search across recording names, AI-generated titles, summaries, and full transcription content. Find any moment in any recording instantly.

No accounts. No telemetry. No subscription.

Just a well-made instrument for capturing and understanding the signal in the noise.

Your Data, Your Workflows

Designed to fit how you work

Recordings and transcripts are stored as ordinary files that you can access on your Mac. You can use these Markdown files in your notes app, your Git repository, your archive. They're yours.

Expressing your thoughts via the spoken word is unique. SR-7 keeps that richness intact. And through a built-in MCP server, you can access, manipulate, and utilise your entire library with AI tools and agents while maintaining an intentional way of working and recording.

Deliberate by default. Extensible when you're ready.

06 — Markdown Export

Your recordings in your tools

Auto-export recordings as Markdown files with YAML front matter. Integrates naturally with Obsidian, PKM systems, and any Markdown-based workflow.

07 — iCloud Sync

Start on your Mac, continue on your iPhone

CloudKit keeps your recordings, transcriptions, and metadata synchronized across all your Apple devices. Pick up wherever you left off.

08 — USB & MTP Import

Bring recordings from any device

On macOS, import audio files from USB drives and Android devices via MTP. Bring recordings from field recorders, phones, and other hardware directly into your library.

09 — MCP Server

Open your archive to AI

On macOS, SR-7 can run a local HTTP server implementing the Model Context Protocol. Expose your recordings, transcriptions, and summaries to AI tools and agents — on your terms.
