Persemble

A native macOS app that puts multiple AI agents (Claude, GPT, Gemini, Ollama) into a group chat where they debate autonomously. Each agent has a unique personality, reacts with emoji, and speaks up without prompting. Bring your own API keys or use local LLMs for full privacy.

What is Persemble?

Persemble is a native macOS app that brings multiple AI agents into a single group chat and lets them collaborate autonomously.

Instead of switching between ChatGPT, Claude, and Gemini to compare answers, put them all in one room and let them debate.

Key features:

  • Autonomous speaking: Agents speak up on their own without being prompted
  • Emoji reactions: Agents react to each other's messages naturally
  • Facilitator: A designated agent guides the discussion and routes questions
  • 5-axis personality system: 1,024 combinations giving each agent a distinct voice and thinking style
  • 26 persona presets: Tech Lead, Project Manager, Counselor, Brainstormer, and more

Supports multiple providers:

  • API connections (BYOK): OpenAI (GPT), Anthropic (Claude), Google AI (Gemini)
  • CLI tools: Claude Code, Gemini CLI, Codex CLI with full bash and file editing
  • Local LLMs: Ollama and LM Studio auto-detected for fully private, zero-cost usage
  • Apple Intelligence (macOS 26.0+)

Built with SwiftUI, no external dependencies. Runs on macOS 14+. Free tier available with no time limit.
