Visualize ChatGPT and Claude conversations as interactive trees
See the entire conversation flow as a tree/graph so you can grasp its structure at a glance.
Switch between different conversation paths instead of scrolling through a long linear thread.
Search across your whole chat history to find a specific message quickly.
Export conversations to Markdown, Obsidian or XML for note-taking and structured documentation.

Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
