You can upload files as well as chat, and as you go, it updates a "Financial Picture" with relevant facts about your situation, so you can see what data has been collected, track goals, etc. this picture along with recent chat interactions is fed into the model each turn so the most important details are always in context.
Your data can be exported or account deleted from the Settings page at any time, or you can interact anonymously until LLM spending gets too hot.
