How to use it

Ask AI to find the expense ratio of every fund you own
Ask AI for the cheapest index alternative in your 401(k)
Ask AI to math the lifetime cost of your current fees
Ask AI which fees are hidden in 12b-1 charges

Try it

Log into your 401(k) or brokerage. Ask AI to audit fees on every fund and switch to the cheap index version this month.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

Ask AI to explain expense ratio in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "AI and investment fee audit: find the 1% killing your retirement" and ask for two possible next steps plus one reason each step might be wrong.
Check fees against a trusted source, teacher, adult, expert, or original document before you use it.
