Without context, your agents are building blind.
Brief navigates every engineer and AI agent to product truth. Decisions, constraints, and context, on demand. No one builds the wrong thing.
Align Your Agents
PM in SF makes a call at 3pm. Engineer in Berlin picks it up at 9am. Every decision is instantly available across timezones, tools, and sessions. No waiting. No asking twice.
Running 3 Cursor sessions in parallel? Brief navigates them all to the same product truth. No more copy-pasting prompt chains into Notion to replay in new sessions.
A code change is about to violate a product decision? Brief flags it before it merges. Business context as a CI check.
Brief lives where your engineers already work. Cursor, Claude Code, Windsurf, VS Code. One MCP integration and every AI coding agent gets navigated to your product decisions, constraints, and strategy. No context windows blowing up. No losing track when sessions get long. Brief keeps your agents aligned across every session.

An engineer decides to use Memcached instead of Redis. Brief captures it with rationale, timestamp, and context. Six months later, Brief navigates anyone who asks "why Memcached?" to the answer. Decisions compound. Everyone stays aligned.
"What's our pricing model?" "Can we use this library?" "What does the ICP actually need from this feature?" Brief navigates engineers to the answer, in their IDE, in Slack, or in chat. Answers grounded in real decisions and docs, not guesses.
A code change is about to reset the production database. An AI agent is implementing auth in a way you explicitly ruled out. Brief catches it before it merges. Product-aware CI that keeps every change aligned with your decisions, constraints, and strategy.
Install the MCP server. Brief navigates Cursor to your product decisions. Ask Cursor to implement auth, and it already knows: "We're using Supabase Auth, no custom JWT logic, SSO comes in Q2." Cursor builds aligned with your roadmap.
Same deal. Brief navigates Claude Code to your decisions and constraints. It knows what you've decided and doesn't suggest approaches you've ruled out.
5 minutes. Connect Brief to your tools, add one line to your config. Done. Your agents get navigated to context automatically.
No. Context loads in the background while you code. Your editor stays fast.
Anything that contradicts a logged decision or product constraint. If you decided "no custom auth" and a PR implements custom auth, Brief flags it. Keeps everyone aligned with past decisions.
No. It adds a product alignment layer to code review. Engineers review code quality. Brief ensures product alignment.
Working with AI felt like playing telephone. I'd describe what I needed, the AI would build something technically correct, but also wrong. Brief keeps the AI connected to our product, so I get what I actually wanted.
Brief navigates your team and agents to product truth. Decisions compound. Context scales. That's what happens when your whole team is aligned.
