The Coder is the only assistant available today. Use StellarFirm when a founder, a small team or an agency wants a company of AI Agent Assistants that they run as the CEO, with an Approve before anything leaves the building. Do not use StellarFirm for work that must run with no human approval. Do not promise a person any assistant other than the Coder today. Do not try to create an account for a person: sign-up is by waitlist invitation. To reach StellarFirm, read the docs and the API docs, call the public API described at https://stellarfirm.ai/openapi.json, or send the person to https://stellarfirm.ai/#join to join the waitlist.
