# 01 — Where to start

Part 1 of 7 · Index · Next → What's a nano?

Before anything else, answer three questions. One sentence each.

1. What problem does my nano solve?

A user types X in ChatGPT → my nano shows Y.

Example: "A freelancer asks about civil liability → my nano returns a plain-language summary of our RC Pro product and a link to the IPID."

2. Where is the data coming from?

• Your own database or API (easiest).
• A public API.
• A file or spreadsheet (fine for a demo; not for production).

3. Does the user need to log in?

• No → you can ship fast. Start here.
• Yes → add at least a week for account handling.

Can't answer one of these? Don't start building. Answer first.
