A Nexus Software Laboratories product

Obsius

Bidirectional Supernote and Obsidian integration with lossless page artifacts, handwriting recognition, and sync-agnostic vault output.

Connects your Supernote e-ink device to your Obsidian vault, in both directions — captured pages stay an immutable source, recognized text becomes the living, editable artifact.

Product screenshots coming soon.

Why Obsius

Ink Stays Ink

Captured notebooks are read, never written. It's a structural guarantee, not a careful-coding promise — no code path can damage your handwriting.

Bidirectional, Not Read-Only

Push a text mirror back to the device, ingest edits made there, and round-trip checkboxes — edits flow both ways once a page becomes text.

Outbound Only

No component ever requires an inbound firewall rule, and the transport encrypts before upload — the sync engine never sees your plaintext.

Works With the Vault You Already Have

Sync-agnostic by design: use whatever Obsidian sync you already run, self-hosted or vendor cloud. Obsius never requires its own sync service.
