One private financial workspace

See your whole financial life. Understand what matters. Make better decisions with it.

Household cash flow, property, investments, crypto, metals, tax readiness and the decisions you make with them, in one place. The Financial Pulse keeps unknowns visible, shows what changed since your last review, and preserves the reasoning behind every decision.

No sign-in to explore. The workspace is free. A report to take with you is $49, no subscription.

See

What do I own, owe, earn, spend and need?

Cash, income, bills, subscriptions, holdings, property and tax records in one private picture. Unknowns stay visible instead of becoming zero.

Understand

What changed, where is pressure building, what is incomplete?

One stored observation per day you open the pulse. Merlin compares it with your last review and names the rule behind every attention item.

Decide

What are my options and their tradeoffs?

Model a sale or a response to a tight week, compare alternatives, save the reasoning, and see when the facts it rested on change.

Not another portfolio tracker.

A tracker tells you what you own. Sigil One tells you what your financial state means, and keeps the reasoning behind what you decide.

Current records, possible decisions and completed activity stay separate. Every figure carries its source, unknown stays unknown, and a saved decision flags the day its facts change.

Six doors, one workspace

Start where your money is.

Every door leads into the same private financial state and the same Financial Pulse. Add what you know first; each prompt afterwards says what adding more unlocks.

Is the month covered?

Household money

See
Income, bills, subscriptions, available cash and the budget in one place.
Understand
Where the tight days fall, what is still unknown and which bills deserve a look.
Decide
Compare responses to a shortfall and keep the reasoning.

Start with one balance and one bill. It unlocks a cash-flow outlook for the next 30 days.

What does each property contribute?

Property

See
Entered value, loan balance, equity, income and recurring costs per property.
Understand
Which property carries the household and where information is missing.
Decide
Compare properties before you change one.

Start with a property and its entered value. It unlocks known equity once the loan balance is linked.

How concentrated am I?

Investments, crypto and metals

See
Holdings across crypto, stocks and funds, metals and real estate with their cost basis.
Understand
Concentration, what each position is worth at the prices you enter, and what is unknown.
Decide
Model a sale before you make it.

Start with one holding, its quantity and basis. It unlocks position value and concentration across everything you own.

Am I ready for my CPA?

Tax readiness and evidence

See
Expected documents, basis gaps, unlinked evidence and completed disposals.
Understand
What is missing before tax season and which questions to bring to a CPA.
Decide
Resolve the gaps, then take a report with you.

Start with the documents you expect this year. It unlocks readiness tracking and CPA questions built from your records.

What would this sale mean?

A financial decision

See
Proceeds after estimated tax at the rates you choose.
Understand
How another move compares and which facts the outcome rests on.
Decide
Save the decision, revisit it, and see what changed since.

Start with one position and a possible sale price. It unlocks a saved decision that flags when its facts change.

Where does my whole financial life stand?

Financial Pulse

See
Known financial position, cash, obligations, assets and property together.
Understand
What changed since your last review and what deserves attention.
Decide
Act on the prompts that unlock the most value next.

Start with a household. It unlocks a daily observation you can compare against later.

Take this question to your CPA

Are this basis, holding period, and rate appropriate, and what facts could change the result?

Inspect the calculation and its limits

Proposed proceeds = units × chosen sale price. Modeled gain or loss = proceeds − the units' entered basis. Estimated federal tax = positive gain × 24%. Proceeds after the estimate = proposed proceeds − estimated federal tax.

All amounts are USD. Loss offsets, other income, net investment income tax, state tax, fees, special asset treatment, and final filing requirements are outside this illustration. A modeled loss has no estimated tax benefit here. Filled-in inputs do not establish source accuracy.

Four asset types. A place to work through each.

Manual entry across all four. Supported crypto imports after review. Positions are valued at the prices you enter and say so; sale estimates use selected capital-gains rates, without asset-specific tax treatment.

Property records and import review

Keep annual local and school property-tax bills by property and year, link rent, mortgage and other costs to the property they belong to, and see each property's equity and monthly contribution in the Financial Pulse. Crypto rows remain staged until you review and confirm them into planning records.

Private household state stays private: explicit permissions, provenance on every figure, unknowns kept unknown, and no advertising built on your financial records.

Before you begin

A few practical questions.

What is Sigil One?

One private workspace for your whole financial life: household cash flow and budget, property, investments, crypto and metals, tax readiness and saved decisions. Start from any one of them. The Financial Pulse brings them together and shows what changed since your last review.

Is it tax software or tax advice?

Sigil One supports planning and review. It does not file taxes, calculate your final tax bill or provide professional tax advice. Estimates depend on your selected assumptions and available records. Review final treatment with your CPA.

What can I do for free?

Everything in the workspace: the Financial Pulse, household cash flow and budget, holdings across four asset types, property intelligence, tax readiness, Merlin observations, daily observations and saved decisions. Try the fictional examples without an account. No wallet, exchange or bank connection is required.

What am I paying $49 for?

One portable output: a CPA Handoff Package, a Holdings PDF or a CPA Disposal Report. Each is a separate $49 purchase. The package can contain one or more selected saved decisions. There is no subscription.

What do I get by coming back?

Each day you open the Financial Pulse, Sigil stores one observation of your known position and compares it with your last review: what moved, which recurring costs grew, which property changed, which saved decision now rests on changed facts. Nothing is reconstructed from current facts and nothing is predicted.

Does Sigil use live market prices?

Positions are valued at the prices you enter, and the page says so. Public on-chain reference prices for crypto, gold and silver are read only where a deployment has an authorized price-feed gateway configured; until then live reference prices are marked as not enabled. Stocks, funds and property always use what you enter.

What assets are supported?

Crypto, stocks, ETFs and funds, real estate and REIT holdings, and physical or paper metals. Crypto supports reviewed file imports, manual entry and optional read-only transaction evidence from a public Bitcoin address. Address activity does not establish cost basis. Other assets use manual entry, including annual local and school property-tax records.

What happens when cost basis or records are incomplete?

Missing information stays visible. Unknown basis is never treated as zero, and an estimate that requires it remains incomplete. Every prompt for more information says what adding it unlocks.

Who can see my household?

Only you, unless you invite a member and grant exactly what they may see. Every figure carries its provenance, history is kept rather than rewritten, and no advertising is built on your financial records.

Start with what you know.

One balance and one bill are enough to begin. The picture grows with what you add.
