DotArc

DotArc is a companion app for Dota 2 players who want sharper drafts, smarter item builds, and real coaching between games.

Draft Assistant
Get AI-backed hero recommendations as the draft unfolds — picks are scored against your enemy and ally lineup, with plain-language reasoning so you understand the why, not just the what.

Adaptive Item Builds
Track your build against suggested item timings, with counter-item suggestions that adjust as the enemy team's threats become clear.

AI Coach
Get a post-match breakdown of what went right and wrong, ask follow-up questions in chat, and dig into a specific match's details when you want to understand a loss (or repeat a win).

Player Profile
Sign in with Steam to see your hero pool, recent matches, MMR trend, and win rate — all in one place.

DotArc Pro
A subscription unlocks deeper draft explanations, full match analysis, and unlimited coach chat. The core app is free to use, with the option to upgrade.
