Coze

Coze is a no-code platform for assembling AI agents: you wire up prompts, workflows, plugins and a knowledge base in a visual builder, then publish. The publishing half is what distinguishes it from a prompt playground — an agent can go out to messaging platforms or be embedded via SDK and API, so it reaches users instead of staying a demo. That makes it a reasonable way to validate an AI feature before committing engineering time. International and mainland versions run as separate platforms with separate accounts.
