Aura

Aura is a notes and chat app with an ambient brain. You talk or jot things down, by text or voice, and Aura quietly remembers everything in a persistent memory layer (HydraDB), connects to your real tools (Gmail, Calendar, Notion, Slack), and works in the background. It reads your inbox, drafts replies in your voice, and surfaces a single card when something genuinely needs you, which you approve with one tap. It can pay with a virtual card and act on your context, like offering to grab.
