Stats tell you what happened.
CS2Brain tells you what's happening.
A real-time tactical overlay built only for Counter-Strike 2. It reads the live game and speaks in the moments you can actually listen — freeze time, after you die, between rounds. Never mid-fight. Whether it's your first month or your five-thousandth hour, it meets you where you are.
Rendered from each map's real walkable-area data
Built for Real Moments
It speaks when you can listen.
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.

Something for Everyone
It meets you where you are.
A first-week player and a 25k veteran don't need the same coach. The overlay is tier-aware — same round, same moment, a different overlay for each of them. Never above your head, never beneath your level.
Full-depth intel: economy reads with confidence, retake timing, trade discipline. The game-sense layer that mechanics alone never gave you.

Core Intelligence
Four Pillars.
Every feature exists to give you an edge in the moments that matter.
Freeze-Time Edge Advisor
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.
Enemy Pattern Tracker
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.
Death Autopsy
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.
Round Win Intelligence
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.

Common Questions
Straight Answers.
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.
Stop guessing.
Start knowing.
CS2Brain is in closed beta and completely free for testers. Grab a spot, plug it into your Steam Overlay, and hear what your matches have been trying to tell you.
