A number you can actually trust.

Money decisions are too important to hand to a black box — or to a chatbot that guesses. Here’s exactly how InvestEd reaches an answer, and why you can rely on it.

The core promise

Our AI can’t make a number up.

It isn’t a promise to behave — it’s how the product is built. The AI has no path to producing a figure. Every number you see is computed by a deterministic engine and simply read aloud.

A general chatbot

Generates text that sounds right. Ask it your numbers and it may invent a plausible figure, drift between answers, and state a wrong one with total confidence.

InvestEd’s companion

Reads the engine’s output and explains it. It can propose an input change — but the engine recomputes the real result. No guessing, no drift, no confident wrong answers.

Four commitments

What we hold ourselves to.

01 · Deterministic

Same inputs, same answer — always.

No randomness, no Monte-Carlo fog. The engine runs your numbers month by month, so a result is fully reproducible and you could check the arithmetic yourself.

02 · Grounded

Every word tied to your numbers.

The companion only ever references figures the engine produced for your exact scenario — never generic advice borrowed from someone else's situation.

03 · Private

No bank logins. Ever.

You type the numbers you want to model. There's no account scraping, no card access, and nothing to leak — the model runs on what you choose to share.

04 · Reversible

Explore without consequences.

Branch a scenario, change a rate, model a refinance — your original always stays put. Nothing you try here touches your real money.

Methodology

Boring math, on purpose.

Trust comes from principles you can inspect, not a clever model you have to take on faith.

∑

Established principles

Standard time-value-of-money math — not a rule of thumb, and not a proprietary secret sauce.

≡

Precise, not rounded

Month-by-month, to the dollar. No blended averages hiding the moment a decision actually flips.

□

One source of truth

The engine computes; the AI narrates. They can never disagree, because only one of them owns the numbers.

Worked examples

See it on a real question.

Same engine, three common decisions. Every figure below is a worked result you could reproduce by hand.

Debt vs invest

A $48,000 loan at 6.4%, or invest $900/mo instead?

Invest, by ~$53k
Break-even at year 7 · holds under 8%
Can I afford it?

A $2,400/mo payment on a $95,000 household income.

14% margin
Comfortable · headroom for a 1% rate rise
On track for FIRE?

$1,800/mo for 30 years at a 7% expected return.

~$2.1M
Clears a $1.9M target · 3 years early

Where we stop

A decision tool — not financial advice.

InvestEd shows what happens to your numbers under each choice, and explains why. It doesn’t know your whole life, and it won’t tell you what to do. The verdict is a clear starting point — the decision stays yours.
