Description

Real-time collaborative brainstorming with coding agents. One person hosts a shared board on your LAN; each participant's Claude Code publishes a Context Capsule, and anyone can riff on someone else's thread.

Introduction

Five engineers are in a room brainstorming. Everyone has Claude Code open on their own laptop. Everyone is exploring a different angle. But there is **no shared surface** — so the group can't see what each person's agent is discovering, can't build on a promising thread, and can't hand a line of thinking from one person to another. One person ends up driving while the rest watch. The collective intelligence in the room goes to waste.

**Riff fixes that.** It gives the room a shared board. Each participant's Claude Code session publishes a compact **Context Capsule** — a summary of what they're exploring, what they've found, and what's still open. Everyone sees everyone's capsules update in real time. When you spot a thread worth building on, you **Riff** on it: that person's context lands in _your_ Claude Code session — no copy-paste, no manual handoff. The board tracks the lineage as the group's thinking evolves.

Riff is **local-first**: one person runs `riff start`, everyone else opens a URL on the same network. No accounts, no cloud, no data leaving the room.
