Tokenyst

Tokenyst이란?

Track your GitHub Copilot Chat usage, estimate token costs, and watch your spend against a monthly budget all from a VS Code sidebar and the status bar. Tokenyst is strictly local. It reads Copilot's own session files on your machine, estimates costs from a pricing table baked into the extension, and stores everything in a single JSON file under your home directory. Nothing is sent to any Tokenyst server.
