Every recording is exported as a Markdown file with YAML frontmatter, making it easy to integrate with note-taking tools like Obsidian or version control systems like git. Its built-in local MCP server enables querying the archive with AI tools such as Claude Code, enhancing its utility for developers, researchers, and professionals who need a secure, integrated workflow. With a straightforward one-time purchase of $7.99, SR-7 offers a seamless, experience-first design that keeps users focused on their recordings without distractions, making it ideal for those who prioritize privacy and simplicity in their voice note management.
