Big Copilot

Drop a Big Ambitions save. Everything is read in this tab and nothing leaves it.

Drop your save folder anywhere

Choose Windows or macOS to see its save folder, or select a .hsg file.

Where is my save?

Choose the Big Ambitions folder inside SaveGames; the page finds the newest save across the company folders inside it.

If you cannot find it, the game shows you: on its Load Game screen, click Browse savegame folder… and the folder opens in a file window.

The game autosaves every five minutes. Your browser may call folder access an "upload" or ask to "let this site view files"; the save stays on your computer. Checked on game build 3682; the Python runtime the page needs is about 6 MB, fetched once and cached.

Linked to the game. With the Big Copilot Link mod from the Steam Workshop enabled, click Link to the game and the board reads the running game itself. Chrome and Edge ask once to allow the site to reach your computer; the data still never leaves it.

Game text

Names, recipes and station capacities come with the page, from game build 3682.

If your game is newer, click the chip and choose its en.json; it is remembered in this browser and wins over the built-in text.

To find your game's en.json, open Steam → Manage → Browse local files. On macOS, search that folder for en.json; use Show Package Contents if the game files are inside an app bundle.

· the page only reads your saves, from a folder or from the running game.
