Frequently asked questions.
Is it really read-only?
Yes. PrinceJohn connects to your brokerage through Plaid with read-only access. It can see positions, balances, and transactions — it has no ability to place, modify, or cancel orders.
Which brokerages can I connect?
Any brokerage Plaid supports for investment accounts — including Robinhood, Fidelity, and Charles Schwab, among many others.
Does the AI trade for me?
No. The agent produces recommendations with written reasoning. You decide what, if anything, to do with them — nothing is ever executed on your behalf.
What does it cost?
Nothing right now. PrinceJohn is free during early access, with no credit card required.
How do I get alerts?
Recommendations and invalidation alerts show up on the web dashboard, and on Telegram once you link the PrinceJohn bot in Settings.
Can I delete my data?
Yes. Settings → Account → Delete account removes your account and the data associated with it.
