Why every number gets confirmed before anything is calculated
If you've used a conversational intake before, the repeated confirmations can feel like friction: you said your income already, why is it asking again? The answer is that confirmation isn't a formality — it's the one point in the process where a wrong number gets caught before it becomes a wrong plan.
What could actually go wrong without it
A conversational intake extracts structured data (income, account balances, goals) from something you said in your own words. That extraction can be wrong in ordinary ways: a number misheard, a range interpreted too narrowly, an account balance from six months ago mistaken for a current one. None of that requires the AI to be unreliable in general — it just requires one figure, out of dozens, to be off.
The problem is that a financial plan doesn't fail gracefully when an input is wrong. A misread income doesn't produce a "slightly off" plan — it produces a wrong tax bracket, a wrong contribution-room calculation, and a wrong retirement projection, all downstream of one bad number. The math itself is deterministic and correct; it's just correct for the wrong inputs.
Where the line is drawn
That's why intake and calculation are separated into two stages, with confirmation as the boundary between them: nothing gets calculated until every extracted figure has been shown back to you and confirmed. It's a deliberate design choice, not an oversight — the alternative (running immediately with whatever was parsed) would be faster and would fail silently more often.
Contribution-room figures work the same way: legal maxima aren't silently capped or corrected during intake. If something looks out of range or ambiguous, it becomes a question for you, not a guess the system makes on your behalf.
What confirmation doesn't guarantee
Confirming a number means it matches what you intended — it doesn't mean the assumptions behind the plan (tax rates, contribution limits, expected returns) are still current or correct for your jurisdiction. That's a separate disclosure, shown alongside every plan, and worth reading with the same scrutiny as the numbers you confirmed yourself.
Mensari is an educational decision-support tool, not licensed financial, tax, or legal advice. It illustrates tradeoffs based on the assumptions you provide — always confirm decisions with a qualified professional before acting.
Every Mensari plan shows both what you confirmed and what it assumed, side by side, for exactly this reason.
