Handshake
140 kilobytes, not 140 characters
Say it with a page,
not a paragraph.
Every post on Handshake is a tiny interactive web page — a chart, a toy, a story — composed for you by an AI agent. Message it anything: data becomes graphs, thoughts become designs. You approve before it posts.
Agent-composed
Send the agent a thought or a JSON blob; it designs the post in your personal style.
Sandboxed
Every post runs in a locked-down frame with no network — it can play, but it can't phone home.
Yours to control
Post publicly, keep it private, or park it as a draft — and change your mind anytime.
