Good to know

• Text, photos (plates, nutrition labels, restaurant bills), dictation and ChatGPT voice all work. ChatGPT or Claude reads them and estimates the nutrition; Nexus saves it.
• Any entry can be corrected on the card or by saying so; totals update.
• Try the tools and card without an account in the sandbox.
• Nexus is a log, not medical advice, diagnosis or treatment guidance.
