Zermind – Open Source AI Conversation Platform

Privacy Policy · Terms of Use · Imprint ·

Zermind is an open-source AI conversation platform that revolutionizes how you interact with multiple LLM providers through dual interaction modes: traditional chat and groundbreaking conversational mind maps.

Transform linear conversations into visual thinking – Where AI conversations themselves become explorable mind maps, enabling branching dialogues, multi-model debates, and resumable conversation trees.

Features

Dual-Mode Innovation

• Chat Mode: Traditional linear conversation interface
• Mind Mode: Revolutionary conversational mind mapping
• Seamless Switching: Convert any chat to mind map with one click

Conversational Mind Maps

• Node-Based Conversations: Each mind map node represents a conversation point
• Multi-Model Branching: Ask the same question to different LLMs visually
• Resumable Nodes: Click any node to continue that conversation thread
• Visual Flow: See conversation logic and idea progression at a glance
• Smart Auto-Layout: Automatic positioning for clean visualization

Enhanced Multi-LLM Support

• Model Selection per Branch: Choose different models for different conversation paths
• Side-by-Side Responses: Visual comparison of how models approach problems
• Conversation Handoffs: Seamlessly pass conversation context between models

Real-time Collaboration

• Collaborative Mind Maps: Multiple users editing the same conversation tree
• Conversation Ownership: Track who created which branches

BYOK (Bring Your Own Key)

• Multi-Provider Support: OpenRouter, OpenAI, Anthropic, Meta, Google
• Smart Fallbacks: Automatic OpenRouter fallback when no user keys exist
• Key Previews: Never display full keys in UI

What Makes Zermind Revolutionary

Category Creation

Zermind doesn't just use AI to create mind maps – it turns AI conversations into mind maps. We're creating the "Conversational AI Visualization" category.

Visual Thinking

Transform complex ideas from linear chat limitations into explorable, shareable knowledge trees that reveal conversation logic and enable true multi-perspective AI collaboration.

"What If" Scenarios Made Visual

• "What if I asked Claude instead of GPT-4?" → Create a branch and see both responses
• "What if we approached this differently?" → Branch from any conversation point
• "What would multiple AIs think?" → Multi-model debates in visual format

---

Supported Providers

• OpenRouter - Access to 100+ AI models (fallback for all users)
• OpenAI - GPT models with your credits
• Anthropic - Claude models with your credits
• Meta - Llama models with your credits
• Google - Gemini models with your credits

See docs/byok.md for detailed security implementation.
