Brief

A PRD tells the agent what to build. A wireframe tells it how the app actually fits together. Brief lets you sketch the flow, attach it to the PRD, and hand the agent something it can read. Not a paragraph. Not a PNG. A structure.

Log a bug in Slack. Brief pulls in the related PRDs, past fixes, and customer context automatically. No new tool. No copy-paste. The bug report writes itself.

Dumping every doc into a vector store isn't context. It's a bigger haystack. Brief reads your sources through a product lens. Interviews, analytics, past fixes, and what to explore next. AI Ships. Brief Navigates.

Your agent doesn't need every file. It needs the right ones for this ticket. Brief's CLI onboards any coding agent in one command, then hands it a focused "book report" per task. Relevant context only, kept outside the context window. Full context. Full window.

Build phase has always been a real-time interrupt loop. Engineers ask the PM when they hit questions planning didn't cover. Coding agents do the same thing. They interrupt you. Brief lets them ask Brief. Less interrupts. Same answers.

Brooks's Law: adding people to a late project makes it later. Same goes for your coding agents. Every context reset is a new hire who needs onboarding. Brief CLI lets the new agent ask Brief directly. No more answering the same onboarding questions every time.

PMs at the speed of AI.

Brief synthesizes your ideas, spins off sub-agents on market, analytics, sentiment, sales.

The trifecta model assumed engineering was the bottleneck. Coding agents flipped it.

Stop your agents from building blind.

Our CLI lets your coding agents talk to Brief directly. Instead of dumping a pile of context, Brief routes the agent to the specific piece of customer feedback, decision, or constraint it needs for the task in front of it. No manual intervention. No 800-line cursorrules file.

Customer feedback is the lifeblood of product development. So how is your coding agent hearing any of it? Right now you probably have three options, and they all break in different ways

Brief is the Navigator. Stop building blind.

Context without a Navigator is just a bigger haystack

Coding agents have plenty of context. They cannot tell you which piece matters right now.
