Private beta · EUW · Win-probability coaching for League of Legends
Know exactly where the game flipped.
NiCoach replays every match as a win-probability curve, pins the moments that swung it, and names the play that would have swung it back. Then it coaches your next game live — one call at a time, drawn over the client.
−14.2% win probability. NiCoach's call: reset and group for Baron instead — the dashed line is that game.
Your match, as evidence.
After every game, NiCoach rebuilds the whole match as a win-probability timeline. Every death, objective, and rotation is scored by what it actually cost — not by how it felt.
The graph is colored by impact
Find the three moments that decided the game in five seconds. Deaths, drakes, backs — each with its exact swing.
Down to the map zone
Each swing gets a place, the numbers behind it, and the decision that caused it — down to "died at raptors without vision."
Every claim carries its basis
Recommendations show their data basis and the model's reliability tier. When NiCoach isn't sure, it says so.
Not "play better." The exact play.
NiCoach re-scores the game with one decision changed — recall, rotate, trade, reset — and keeps only the change that genuinely moves your win probability. That surviving change is the recommendation. No horoscope tips, no "ward more."
Better: rotate mid-to-bot at 23:30 with numbers 4v3 — projected +6.2%.
A coach in the corner, not a dashboard on your screen.
In game, a transparent overlay shows at most one call at a time, with the number that justifies it. Objective timers, respawn math, buff clocks — live, and gone when they're not relevant.
Tips are capped at one on purpose. A second only appears when a defensive guard pairs with an attacking call.
Three steps, then it's just your games.
Sign in
Your tester account lives at id.nivasec.de. Sign-ins are allowlisted — this beta is a handful of Iron–Gold players on EUW.
Install & link
Run the small Windows installer once, sign in, and link your Riot ID. The shell loads the app from coach.nivasec.de — it keeps itself current.
Play
The overlay coaches live; the review lands right after the game.
The coaching engine and the live game reader run locally. Your match history is fetched by our server with our Riot API key — you never handle a key. We store your account, your linked Riot ID, and the feedback you send. Nothing else leaves your machine.
Get the client. Once.
One small installer: the shell plus the local companion — engine, live game reader, overlay. After sign-in the shell loads the app straight from coach.nivasec.de, so updates reach you instantly. No reinstalling.
The installer isn't up yet — it lands here the moment K5 ships.
