What to expect

These assistants explain concepts from curated knowledge bases. They do not browse the live web, run your code, or solve every exercise. They can misunderstand a question. Source links and our learning guides help you check the details.

Start immediately with keyword matching. Enhanced matching downloads a model of about 22 MB when you choose it, then caches it in your browser. Offline access depends on which pages and assets you have already loaded.
