Download Tandem
For Mac and Linux. Free on your own and for hackathons; bring the AI tools you already use.
Early builds aren't signed by Apple yet. The first time you open Tandem, macOS may say it can't check the developer. Right-click Tandem in Applications, choose Open, then Open again. You only do this once.
