Try NOVA-3 in your browser.

Pick what you want to do — design candidates for a target, fold a sequence, or verify an Evidence Bundle on Bitcoin. All three call the real NOVA-3 backend.

Design candidates

Target Modality Affinity goal (pM)

Try a preset

Design output Idle

Pick a target. Press run.

NOVA-3 will search the Module Library, generate multi-specific combinations, rank by predicted Kd, and anchor the result to Bitcoin.

Fold sequence

Amino-acid sequence (single chain, ≤ 400 aa)

Preset sequences

Sequences sent to the live folder go to Meta’s public ESMFold API — do not submit confidential or regulated data.

Mol* · ESMFold result Idle

Paste a sequence. Get a structure.

Real ESMFold call via the NOVA-3 backend. Mol* renders the structure with pLDDT confidence colouring. 5–30 seconds.

Verify Evidence Bundle

Bundle ID

Demo bundles

OpenTimestamps verification Idle

Anyone can verify. No login. Don't trust us.

Every result NOVA-3 produces is anchored as a SHA-256 root committed to Bitcoin via OpenTimestamps. Paste a bundle ID to see its recorded anchor — then verify it yourself, independently, with ots verify <bundle>.ots against the public chain. The point of anchoring is that you never have to take our word for it.
