Brief

What is Brief?

Brief is a product navigation tool that captures, connects, and serves product decisions to both human teams and AI agents. It acts as a living source of truth that preserves the why behind every feature, tradeoff, and requirement. Instead of relying on scattered docs or tribal knowledge, Brief builds a Product Graph from your existing tools—Linear, Jira, Notion, Slack, GitHub—and makes that context available through a web app, CLI, MCP server, and Slack. The result: every builder and every AI agent ships with full alignment to product intent.

Who it's for

• Product managers who need to scale their judgment and ensure strategic decisions reach every builder without constant meetings or status updates.
• Engineering teams that want their AI agents (Cursor, Claude Code, Windsurf) to build the right thing the first time by surfacing relevant decisions and constraints directly in the IDE.
• Engineering leaders who allocate AI token budgets and need to maximize return on every query—reducing rework and wasted context-switching.

Key features

Product Graph

Brief automatically maps decisions from your existing tools into a searchable, linked graph. Every captured decision connects to related context—customer insights, technical tradeoffs, strategic priorities—so nothing lives in isolation.

MCP Server + CLI

Your AI agents get navigated directly from their environment. Cursor, Claude Code, and Windsurf query Brief through the MCP server or CLI, receiving only the context that matters for the task at hand. No more agents building blind.

Integrations with your workflow

Brief pulls decisions from where they already happen—Linear, Jira, Notion, Slack, GitHub. You don't change your workflow; Brief watches your tools and extracts decisions automatically, then connects them to your Product Graph.

Web App command center

The web app gives you a bird's-eye view of your Product Graph. Search past decisions, see where the team is headed, and verify that every builder has the context they need.

What stands out

"Brief navigates you to why it was built that way—not just what exists."

Most tools tell you what the code does or what a ticket says. Brief preserves the reasoning, tradeoffs, and customer context behind every decision. That distinction matters because AI agents can read code, but they can't infer product intent. By serving the why on demand, Brief turns every token query into a high-confidence build action, reducing rework and keeping the entire team aligned from whiteboard sketch to shipped feature.

Worth checking out if…

Your team uses AI coding assistants and you've seen them produce wrong or irrelevant output due to missing product context. Also worth a look if you're a product manager spending too much time repeating decisions across Slack, docs, and meetings—or if you're an engineering leader trying to stretch your AI token budget further by eliminating wasteful agent wandering.
