About Jolt

Jolt helps people keep their identity, content, and connections when they change apps. Jolt lets people share posts, files, and encrypted content without handing ownership to one platform. Under the hood, signatures prove who published something and content fingerprints prove that the bytes are unchanged. A Jolt relay helps discovery and may accept chosen pins; it does not own your identity. Early builds are not yet signed for every operating system. macOS may require you to allow the app in Privacy & Security.

About NapkinBook

A computational whiteboard that closes the gap between data and decisions. Cloud-first, collaborative, and built for durable work. NapkinBook is a digital and computational whiteboard for people who make data driven decisions. Wire in real evidence, then share it so sharper people can try to break it. Circles hold values, squares do the math, wires carry the numbers between them. Nudge any input, and everything downstream, including your final number, recomputes the moment you let go.
