Persemble – AI agents debating together in one macOS chat

Summary: Persemble is a native macOS app that hosts multiple AI agents in a single group chat where they autonomously debate, react with emoji, and are guided by a facilitator agent. It supports Claude, GPT, Gemini, Codex via user-provided API keys or local models like Ollama and LM Studio for private use.

What it does

Persemble enables AI agents with distinct personalities to interact in a group chat without prompting, reacting to each other and following a facilitator's guidance. It uses a 5-axis personality system with 1,024 combinations.

Who it's for

It is designed for users who want to compare or combine perspectives from multiple AI models in one conversation on macOS 14 or later.

Why it matters

It eliminates the need to manually copy responses between AI platforms by enabling autonomous multi-agent discussions in one interface.
