How it works.

01

Connect your accounts

Link via Plaid or enter balances manually. Your financial data is stored securely. Never sold, never shared with AI providers.

02

See your financial picture

Balances, spending, debt rates, net worth, all in one place. LasagnaFi shows you where you stand and tells you exactly which layer to focus on next.

03

Ask anything, fully private

"Am I saving enough?" or "How does my debt compare to my investments?" The AI answers based on your real numbers, but never sees your name, bank, or account details.

04

Get real answers

Personalized information you can explore. Drill down, follow up, run projections. The AI doesn't remember anything between sessions.

Feed it everything.
Get back what to do.

LasagnaFi takes the full picture of your income, accounts, debts, taxes, and goals and turns it into a short list of actions worth your attention.

The Lasagna Layers,
your priority stack.

LAYER 05 OF 12

One uninsured event can reset you to layer 1.

Term life insurance costs $30–60/month and replaces your income for dependents. Disability insurance is even more likely to be needed. 1 in 4 workers are disabled before retirement. A will ensures your assets go where you intend.

Your full picture.
Reasoning that shows its work.

When you ask a question, LasagnaFi assembles a scrubbed bundle of your finances, sends it to a frontier LLM along with your question, and streams back a grounded answer that cites the exact numbers it used.

Yes — but split it.

Put $4,720 into your 401(k) before Dec 31 (saves $1,510 in tax) and use the rest to wipe out your 22.4% card. Math says the card costs you faster than the bracket saves you.

AI that actually knows you.

Most finance apps sell your data.
LasagnaFi scrubs it.

Before any question reaches the AI, identifying information is stripped. The model sees balances and patterns, not your name, institution, or account numbers.

Honest answers.

How can the AI help without seeing my identity?

It does see your numbers: balances, rates, allocations, spending patterns. What it never sees is anything that identifies you: names, bank names, account numbers. Personal details are stripped before any information reaches the AI.

Is this really open source?

The core app, scrub layer, tool definitions, and data schema are all on GitHub. Any managed infrastructure (website, hosted deployment, billing, support) may be proprietary.

Who is this for?

People who want serious personal finance tooling and don't want their household balance sheet sitting in an ad-targeting pipeline or used for training AI models.

Your finances, your data, your control.
