CivAI offers a user-friendly interface for building AI-driven chat agents. With step-by-step wizards, you define each character's system prompts, memory triggers, and personality traits—like tone, interests, and expertise. The platform supports uploading custom instructions and connecting your own OpenAI API key for advanced control over model behavior. Once created, characters can be tested in real-time chat windows, saved to personal libraries, and published to an online gallery where other users can chat, rate, and fork them. CivAI also provides analytics on conversation patterns, enabling iterative refinement and optimization of agent interactions.
