Your money,
fully simulated.

Killion is an AI assistant on every layer of your finances.

Connect what you actually own.

More than $180M in assets connected across 15+ brokerages, banks, and crypto exchanges.

Adjust any assumption
Returns, contributions, inflation, retirement age — instant feedback.
Stress-test reality

We charge a flat subscription. We never get paid by funds, brokers, or advisors.
Your data isn't for sale
No ads, no data brokers, no third-party trackers. Your subscription is how we pay the bills.
