Bank bonuses,
actually worth it.
Magpie scans hundreds of bank-account-bonus offers and ranks them by what they're really worth — the differentiator is true opportunity-cost math on the interest you'd give up locking capital. It tracks cooldowns and eligibility, with an optional bring-your-own-key AI planner. It discovers and tracks only — never opens accounts, holds no bank credentials.
The math behind "is this actually worth it?"
Most bonus trackers list offers. Magpie tells you which ones make you money.
~250+ offers, ranked
Continuously scans offer sources and ranks every bonus worth / marginal / skip, with the reasoning shown.
True opportunity cost
Nets the bonus against the interest you'd give up parking locked capital — the number that actually decides it.
AI tier extraction
Reads each bank's own page to pull the exact deposit tiers and conditions, verified against the source.
Cooldown tracker
Tracks per-bank cooldowns and eligibility so you never burn an offer you can't actually claim yet.
Daily brief
An optional daily email with the new offers worth your attention — and nothing that isn't.
No bank logins
Magpie never connects to your bank or holds credentials — it researches and tracks, you do the opening.
It's a research tool, not a bank. Magpie discovers and tracks offers and does the worth-it math. It never opens accounts, moves money, or holds any bank credentials — you stay in control of every account you open.
