You Know the "Why"
You know why you chose Postgres over MongoDB. Why you're not doing SSO yet. Why the API is structured that way. But your AI doesn't. Every session, you re-explain.
You're Doing Eng, PM, and Design. All at Once.
Brief is your product memory. It gives AI coding agents the context they need so you can focus on building, not re-explaining.
The Founder's Context Problem
As a technical founder, the product strategy lives in your head. That's efficient. Until you try to work with AI coding tools.
Customer Context Is Implicit
You talked to customers yesterday. You know what they need. But when you ask Cursor to build a feature, it builds for generic users, not your actual customers.
Decisions Compound
You've made hundreds of product decisions. They're scattered across Notion, Slack, Linear, and your memory. Finding them takes longer than making new ones.
No Time for Documentation
You could write everything down. But you're shipping features, talking to customers, and building a company. Documentation always loses to shipping.
Brief: Your External Product Brain
Decisions Are Captured
As you make decisions, Brief records them. "We're using Stripe because X." Now every future AI session knows this without you saying it.
Customer Context Travels
Brief stores your personas, their pain points, what they care about. When you ask AI to build a feature, it knows who you're building for.
Strategy Stays Current
Your goals, priorities, and constraints. All accessible to AI. No more explaining "we're not doing that because we're focused on X."
How It Fits Your Workflow
1
Connect Your Tools
Brief pulls context from Linear, Notion, Slack, GitHub. The decisions you've already made, extracted automatically.
2
Connect Your AI
One line of config for Cursor. One command for Claude Code. Your AI can now query Brief.
3
Code With Context
Ask AI to build features. It checks Brief for relevant decisions, customer context, and constraints. You build faster because you're not babysitting.
4
Decisions Accumulate
As you make new decisions, record them. Brief becomes smarter. AI sessions become more productive.
Questions Founders Ask
I'm pre-product-market-fit. Is this useful yet?
Especially useful. You're making decisions rapidly. Customer insights change weekly. Brief captures this so you're not holding it all in memory. And when you onboard your first hire, the context is already documented.
How much time does this take to set up?
Tool integrations: 10 minutes. AI connection: 2 minutes. Brief starts extracting context immediately. You can add context manually as you go, or let it build naturally.
Will this slow me down?
The opposite. You stop re-explaining context every session. AI suggestions are more relevant out of the gate. The time you save on context-setting more than covers the occasional decision recording.
What if I'm the only one using it?
Brief works for teams of one. As a solo founder, you're the entire product org. Brief is your external memory. When you hire, it becomes the onboarding doc that already exists.
Stop Holding Everything in Your Head
You have enough to think about. Let Brief hold your product context so AI can actually help you ship.
