More than a chatbot
A library of Dota 2 ideas, organized by hero and role.
Generate a plan when you need help, browse when you need perspective, and keep every useful idea attached to the hero and role it belongs to.

Private until you say so
Keep experiments private while you test them, then publish only the ideas worth passing on.
My Ideas
Create from scratch
Not every idea starts in the chat. Open the editor, pick a hero and a role, and write the build and timings yourself.
Create Idea
A playbook that remembers
Review saved ideas before you queue and update them after the game. Over time they become a record of what actually worked.

What is an idea on D2Brain?
An idea is a structured Dota 2 game plan tied to a hero and a role: the build, the timings, and the reasoning behind them. Create one from a chat, keep it private, or share it with the community.
