Concept

A second brain in your pocket

Yvo is a markdown-based Zettelkasten that lives in your pocket. Speak a thought, save a link, snap a screenshot — AI handles the rest: transcribing, categorizing, and filing everything into the right place. Your personal AI uses the full vault as long-term memory, acting as a companion that can recall, summarize, and create on your behalf.

Unlike general note apps, Yvo is built around voice-first capture — the fastest way to get something out of your head and into your system. Works across iPhone, Apple Watch, and macOS with a single-tap record.
