TreeOS operations like creating nodes, editing content, and running scripts cost energy. Your balance refills automatically once per day based on your plan.

TreeOS requires you to connect your own LLM provider to use AI features. You bring your own API key and pay your provider directly for LLM usage.

Successful AI chat messages are free and do not cost energy. TreeOS operations triggered by the AI (creating nodes, editing notes, etc.) still cost energy as normal.

If an AI call fails (bad endpoint, invalid key, etc.), 2 energy is charged to prevent abuse.

Your plan determines how much energy you receive each day. TreeOS offers three tiers:

Plans can be purchased or upgraded through your profile page via Stripe. If your plan expires, you're automatically moved back to Basic and your daily energy resets accordingly.

Need more energy beyond your daily refill? You can purchase additional energy packs through Stripe on your profile page. Additional energy doesn't expire daily. It sits in a separate balance and is only consumed after your daily energy runs out.

Your daily energy refills to your plan's limit once every 24 hours, measured from your last reset. The reset replaces your daily balance and does not stack. Additional purchased energy is not affected by the daily reset.

TreeOS requires you to connect your own LLM provider to use AI features like chat, understanding, dreams, and raw idea placement. You can use any OpenAI-compatible API endpoint. We recommend OpenRouter for the easiest setup. It gives you access to hundreds of models with one API key.

TreeOS supports multiple LLM connections so you can use different models for different tasks. There are two levels of assignment:

Each tree can have its own LLM for each stage. If a tree slot isn't set, it falls back to the tree's placement LLM, then to your profile default. This lets you use a fast, cheap model for bulk operations like cleanup and a more capable one for conversation or understanding.
