What is Gearbox Relay?
Learn what Gearbox Relay does and why it exists.
Getting started
Install Gearbox Relay and make your first capture in under five minutes.
How it works
Capture, enrichment, and structure — the three-layer architecture.
Streams
Publish curated collections and subscribe to other curators.
Who is it for?
Researchers tracking hundreds of sources across papers, articles, and notes. Gearbox Relay captures everything and finds connections you didn't notice.
Writers building a second brain. Your research, quotes, and ideas — all searchable by topic, meaning, or exact word.
Developers saving code snippets, documentation, and stack overflow answers. Find that pattern you used three projects ago.
Students organizing lecture notes, textbook highlights, and research. Everything captured, everything connected.
Open source
Gearbox Relay is Apache 2.0. The desktop client, mobile apps, and core engine are all public. No hidden components. No encrypted blobs only we control. Build from source, run your own sync server, verify everything.
Built for privacy
All AI runs on-device. Your highlights never leave your machine unless you choose to sync. Sync is end-to-end encrypted with keys derived from your password. We hold no keys. We cannot see your data. We cannot give anyone access. This is not privacy by policy — it's privacy by architecture.
