About Memos
Memos is an open source, self hosted note taking tool designed for rapid capture of short form content like daily logs, links, code snippets, and microblog style entries. It lives in the Go ecosystem and uses a Markdown native, timeline based interface. Unlike traditional note apps that enforce folders or rigid templates, Memos prioritizes speed and simplicity: users write in Markdown, attach media, and save without selecting titles or locations.
