Frequently looked up
- Q1Is Helicon official or affiliated with Meta?
- No. Helicon is an unofficial community project, MIT licensed. It is not made, sponsored or endorsed by Meta. It is a client for the Muse Code CLI, and uses Meta's trademarks only to describe what Helicon connects to.
- Q2Do I need a separate API key or additional subscription?
- No. Helicon uses your existing Muse Code subscription through the muse CLI with no additional billing. There is no API key requirement and no second bill.
- Q3Where do my Muse Code credentials live?
- Your credentials stay with the muse CLI from your own muse login. Helicon never stores or handles them. Authentication is your own muse login, held by the CLI.
- Q4Can I use sessions I started in the terminal?
- Yes. Sessions started in the terminal TUI show up in the sidebar with full history, and you can resume them in Helicon.
- Q5How does Helicon work on Windows?
- Muse Code runs natively on Windows and Helicon runs it directly using your Windows paths and PowerShell for shell commands, with no WSL required. WSL2 still works, and Helicon uses it when native Muse Code is not installed.
