What DotaMirror is
DotaMirror is a free AI coaching tool for Dota 2. Take the Match ID from any public game, paste it into the field, and within seconds you get a full breakdown. No replay, no upload, no account.
The analysis is built entirely on real numbers from the OpenDota API: KDA, GPM, XPM, item timings, teamfight positioning, farm efficiency. This is not a generic chatbot telling you to farm more. DotaMirror will show you that your Battle Fury landed three minutes later than the average at your MMR, and that this delay is what lost you the crucial Roshan fight. Every observation is anchored to a specific moment in the game and backed by numbers.
The output is a single priority: one concrete thing to fix first so you win the next game. That is what makes DotaMirror different. It will not bury you in a wall of vague text. It tells you exactly what to stop doing next time, and why. The tool is free for everyone and runs straight in the browser, with nothing to download.

What it looks like
How we built it
Anyone can generate text these days. The hard part was forcing the AI to be precise and anchored in numbers. Every observation in DotaMirror is tied to a specific figure from OpenDota. If the engine says you finished Battle Fury late, that is backed by a timestamp from your replay and compared against the average at your MMR. We programmed the system from the ground up to suppress vague output. If the model cannot say something concrete and actionable, it says nothing at all. That is the difference between a useful tool and yet another chatbot.
We tested it for months. On our own games and on community matches. Only then did we put it in front of players.
