Capivar.

See your financial future before you commit to it.

Capivar is AI-powered planning software that turns your real numbers into clear, hypothetical scenarios you can explore — educational modeling, not guesswork.

Capivar is built by Marcus P. Miller, CFP®, MBA, EA. The way an experienced planner frames a decision — assumptions stated, trade-offs modeled side by side — is encoded in the software itself.

Hypothetical scenario analysis

Model retirement timing, savings rates, and big decisions as educational what-if scenarios using your own numbers — and see the trade-offs side by side.
