01
A canvas that remembers
Every page is a durable tldraw document. Draw, type, map, annotate, and return without flattening your thinking into rigid blocks.
A private canvas for serious thinking
Think in ink.
Work with intelligence.
Keryx turns a freeform notebook into an agent-ready workspace—without sending your vault, notes, or gateway through a public application backend.

One workspace, fewer seams
Capture freely.
Structure when it matters.
Keryx keeps the looseness of paper while adding the retrieval, organization, and agent context that digital research demands.
02
Hermes in context
The gateway receives page metadata and OCR transcription, so its answers begin with what you are actually looking at.
03
Your vault stays yours
Export clean Markdown directly into an Obsidian folder. No proprietary sync layer and no plugin-shaped lock-in.

Private working system.
The website explains Keryx. The application runs on your machine, with a server-side proxy that keeps credentials out of the browser and reaches Hermes through your tailnet.
- 01BrowserCanvas and IndexedDB stay close to the user.
- 02Keryx proxySame-origin routes protect service credentials.
- 03TailscaleHermes remains private and addressable by MagicDNS.
- 04NVIDIA APIHosted OCR runs through the sidecar, never directly from the browser.

One Compose file.
A private path to Hermes.
Bring an NVIDIA API key, a Tailscale auth key, your Hermes gateway address, and an Obsidian folder. Keryx handles the rest.
