Plaid handles the authentication. Your bank password never touches Stackr's servers. Read-only by design — Stackr can see balances and transactions, but it can never move your money.

STEP

Ask anything. Get your actual answer.

The coach reads your live balances, transactions, and projections before every response — and cites the account and date for every number. Powered by Claude Opus 4.6.

  • "Am I on track to retire at 60?"
  • "Which debt should I pay off first?"
  • "How much should I put toward my 401(k)?"
  • "What's my tax situation this year?"

Should I max my 401(k) or pay down the mortgage faster?
Reading 401(k) · Mortgage · Running comparison
Max the 401(k). Your employer matches 5% — that's an immediate $8,200/yr. Your mortgage is at 3.1%, well below your expected 6.8% blended return, so extra principal payments cost you the spread. Revisit the question when rates rise.
