Three depths of the same Monte Carlo engine — start free, upgrade only if you want every lever.
The fastest way to a real answer. Enter your age, savings, and target spend — get a success-rate projection and the dials that matter most, no account required.
Launch Quick Planner →A guided, section-by-section wizard covering income, portfolio, spending, healthcare, and Social Security — with 29 AI-narrated findings and a downloadable PDF report.
Launch Planner →Every input on one screen for power users and advisors: couples mode, Roth conversion ladders, RMDs, tax strategy, stress tests, tornado sensitivity, and scenario grids.
Launch Pro →We're rolling out the rest of the suite gradually rather than all at once. Want a heads-up as each one goes live?
Get notified →The add-in that started it all. Fetch SEC filings, run Python with Pandas/NumPy/SciPy, and query multiple LLMs — all from inside the spreadsheet you already use. No dashboards, no exports.
CFPs and firms can commission a bespoke app on this same engine, or license the whole bundle for clients.
