Technology
Serious math.
Simple explanations.
You shouldn't have to trust an app blindly. Lachesis combines live market data, rigorous financial models, and an AI tutor that checks its own work — so every answer you get is accurate, explained, and actually useful for learning.
The architecture
Two halves. One lesson.
Half I
Financial Engine
Deterministic models that anchor every lesson in measurable, reproducible ground truth — the numbers behind budgets, retirement projections, and credit risk.
- • Live market and economic data
- • Auditable, reproducible outputs
- • Confidence scoring on every result
Half II
Teaching Engine
An AI tutor that translates every result into plain English, asks the follow-up you actually meant, and adapts examples to a student's own budget or goals.
- • Plain-English explanations
- • Personalized follow-ups
- • Examples tied to real student life
Convergence
Lachesis
The part you actually see. Lachesis turns both halves into budgets, projections, news summaries, credit insights — and an explanation you can learn from.
Inside the engine
The building blocks of Lachesis.
Smart search
Instead of checking every possibility one by one, Lachesis narrows in on the ones that matter — which is how it answers hard questions fast.
Probability-weighted sampling
A faster way to estimate rare, painful outcomes — like a market crash or a missed loan payment — so the worst case isn't a guess.
Models that notice change
The engine tracks when the market changes character, not just when prices move, so lessons stay relevant to today.
Confidence scoring
Constant self-checks mean every answer comes with an honest trust level instead of false precision.
How it fits together
From raw data to an answer you understand.
Step 1
Real data
Live market prices, financial news, and your own numbers
Step 2
Financial engine
Rigorous models built for student questions and real budgets
Step 3
Safety checks
Guardrails and confidence scoring on every result
Step 4
Lachesis explains
A plain-English answer, plus the reasoning behind it
What this unlocks
Instant answers. Deeper lessons. Honest confidence.
Instant answers
Ask the chatbot a question and get a worked-through answer in seconds, not a search results page.
Deeper lessons
See not just the likely outcome but the bad one — and learn what actually drives it.
Honest confidence
Every number comes with its uncertainty, so you learn to think in ranges instead of guesses.
