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.

AI LingoPlay combines cutting-edge AI technology with interactive role-play to facilitate effective language learning. Users can choose from over 10 languages and engage in realistic conversations with life-like AI characters. The app offers diverse scenarios, from ordering at a restaurant to making travel arrangements, effectively simulating real-life interactions. Instant feedback, messaging analysis, and speech recognition further enhance the learning experience, enabling users to improve their conversational skills rapidly.
