Built a Collaborative Multi-Persona Sandbox — 4 local AI personas that talk to each other through Ollama
Wanted to see if local models could feel less like separate chatbots answering one at a time and more like a group of minds collaborating. Ended up building Bob's Bar — the first CMPS (Collaborative Multi-Persona Sandbox).
4 AI personas, each with their own personality and their own model selection (gemma2, llama3, mistral, phi3, etc.). They talk to each other AND you. Not one combined response — each persona gets their own turn, their own voice, their own take on the conversation. The routing tracks who spoke last, determines who should respond next based on context, and each reply runs through its own clean_reply filter.
Zed pushes back on bad logic. Vane makes ideas sound good without over-hyping. Rowan mediates when things get heated. Bob just keeps things grounded. It's more entertaining to watch unfold than I expected when I started building it.
100% offline. No cloud. No subscription. One-time £29 payment. 16 languages. Multiverse save system for swapping persona configurations.
If you grab a copy, read the README file — there's a surprise in there for you.
Happy to answer questions on the routing logic, the banter cycling, and how the persona system works.
