KnowTree is an AI chat platform that lets you branch conversations like a tree, compare multiple AI models side-by-side, and visualize your exploration as a knowledge map. Unlike linear chat tools, you can explore competing ideas without losing context.

Which AI models does KnowTree support?

KnowTree supports 29 AI models across 5 providers, including frontier models like GPT-5.4 Pro (OpenAI), Claude Opus 4.6 (Anthropic), Gemini 3.1 Pro (Google), Grok 4 (xAI), and Sonar Deep Research (Perplexity).

How is KnowTree different from ChatGPT?

ChatGPT is designed to do everything for everyone. KnowTree is built for one thing: going deep on knowledge that matters to you. It's objective — no memory bleeding between projects. It's non-linear — every message becomes a node you can branch from. It's flexible — switch AI models at any point to pressure-test different perspectives.

The free plan lets you explore the interface and experience branching firsthand — enough to know if this way of learning is for you. Paid plans unlock frontier models like Claude Opus and Gemini Pro, which is where deep learning actually happens.

Do I need my own API keys?

No. KnowTree handles all the AI infrastructure for you. Just sign up and start chatting — no API keys, no setup, no technical knowledge required. You get access to models from OpenAI, Anthropic, Google, xAI, and Perplexity out of the box.

Can I export my conversations?

Yes. You can export any conversation tree as a structured document or share a read-only link with others. Your data is always yours.

Absolutely. Your conversations are stored securely and are never used to train AI models. Each conversation is private to your account, and you can delete your data at any time.
