Muse Code in Threadlines

Questions
What is contributor mode?
A Muse setting that lets Meta use your chats for training, in exchange for longer plan limits. Meta's terms say confidential code shouldn't go there. Threadlines asks before your first chat, and you can change it in Settings.
Does Muse Code work on Windows?
Muse supports Windows, but we haven't tested Threadlines with it there yet. Mac is tested.
Can Muse join a thread with other agents?
Yes. It can't answer side questions while another agent is working, though, because Muse loads your own hooks and MCP servers in every chat.
What does it cost?
Threadlines is free and MIT-licensed. You pay Meta for your Muse plan, or for API usage if you turn that on.
Other agents
Muse Code is made by Meta. Threadlines is an independent open-source project and isn't affiliated with or endorsed by Meta.
