memory.wiki

The fastest way from thought to shared document.

Markdown URLs that humans write and AI reads. Capture from any AI tool. Share anywhere with a permanent short URL.

What is this?

memory.wiki is a document platform with one promise: every document gets a permanent short URL (memory.wiki/abc123) that works everywhere — browsers, AI chats, Slack, email, embeds. No login to view. No paywall.

It ships across 7 channels, all driven by the same shared rendering pipeline (markdown-it + highlight.js + KaTeX + Mermaid) so a doc looks identical wherever you open it.
