The real-time Tactical Co-Pilot for CS2. Know enemy patterns before the round starts. Get instant death analysis with real conditions — flashed, burning, smoked — the moment you die. Track your growth across every match. All through your Steam Overlay.
Not mid-fight. Not while you're clutching. CS2Brain fires in the moments that change rounds — freeze time intel, instant death analysis, and pattern recognition that builds all match long.
Every feature exists to give you an edge in the moments that matter.
Know what the enemy can afford before the round starts — powered by real GSI data, not guesses. See their loss streak, projected buy, and your round-win pattern. Your IGL broadcasts the call, all 5 see it instantly.
CS2Brain tracks how your opponents play — rush frequency, bomb site preference, top weapons, and buy tendencies. Every round adds data. By mid-match, you know exactly what they'll do next.
The moment you die, see the full truth: 74% blinded, burning, holding the wrong weapon, 87 damage dealt. Real GSI conditions captured at the exact frame your health hit zero. Turn every death into a lesson — while the round is still live.
Color-coded round history shows every win reason — elimination, bomb plant, defuse, or time. Win patterns emerge mid-match: 'You've won 4/6 by elimination — keep aggressing.' Cross-session stats track your growth across every match you play.

We know you're skeptical. Good. Here's everything you need to know.
No. CS2Brain uses Valve's official Game State Integration (GSI) API — the same read-only data feed used by tournament organizers and broadcast overlays. It never touches game memory, never injects code, never modifies files. It runs in your browser via Steam Overlay. Zero VAC risk.
Press Shift+Tab to open Steam Overlay, then open CS2Brain in the built-in browser. That's it. You see the tactical board, economy reads, and lineup suggestions right there — no alt-tabbing, no second monitor needed. Close the overlay and you're back in the game instantly.
Zero performance impact. CS2Brain runs in the Steam Overlay browser — a completely separate process from CS2. Your game doesn't know it exists. No CPU spikes, no frame drops, no network overhead beyond a tiny WebSocket connection.
30 seconds. Download one small config file, drop it into your CS2 cfg folder, and restart the game. That's the entire setup. Once it's done, CS2Brain connects automatically every time you play.
No. Only players who want live telemetry need the config file. Everyone can join the tactical room via a simple link or room code — they'll see shared drawings, strats, and utility plans. The IGL can broadcast economy calls to everyone.
Only what you explicitly connect: your CS2 round state (score, kills, economy — never chat or voice), your email for your account, and anonymous usage analytics. We never sell data. You can delete your account and all data at any time.
