Celeste Studio - EverestAPI/CelesteTAS-EverestInterop GitHub Wiki
Celeste Studio is an editor specifically built for editing TAS files efficently. While you can use other text editors to edit TAS files, it's not the recommended methods.
Studio should automatically be installed / updated once you've launched Celeste with the CelesteTAS mod once.
If you have the Launch Studio at Boot setting enabled (can be found under Mod Options > Celeste TAS > More Options), Studio should automatically open alongside the game.
If you wish to manually open it, you can find the program in the CelesteStudio folder inside your Celeste install.
