owncost

The price tag is only the first payment.

OwnCost turns the thing you’re about to buy into what it costs to own, month by month. Every amount is sourced and dated, and every cost nobody can price yet stays visible. When you decide, you approve today’s amount with a passkey. Nothing more.

Your words or photo go to Groq only to read the brief. Nothing is saved.

Watch one shopper go from a brief to a passport.

A 2-minute-54-second walkthrough of the real workspace: a shopping brief, a sourced comparison, a timeline, a passkey-approved test review and the saved record.

Five steps from wanting it to owning it, knowingly.

The workspace keeps each step one tap away, and your progress stays put when you switch between them.

Say it, show it, or type it.

Describe what you want in your own words, attach a product photo, or record your voice. AI proposes the model, usage and timeframe, and you confirm every fact before anything is calculated.

Three options, every dollar sourced.

OwnCost prices three supported products side by side from dated evidence. Anything missing is named as a gap you can fill with a price you found or a ZIP-code tax estimate. It is never quietly set to zero.

See when the money actually leaves.

A month-by-month chart shows each purchase when it happens, like the toner you’ll need in month 8, across anything from one month to ten years.

Approve today. Only today.

Pick one product. The review separates what you’d pay today from the forecast and from costs nobody can price yet. A passkey approves that one amount, once, within five minutes.

Keep the decision, not just the receipt.

The approved amount, its fingerprint, the forecast and its sources are saved together. Change your usage later and the original record stays exactly as it was.

Two futures. The cheaper one changes.

Which option costs less depends on how you’ll use it. Watch two printers trade places, then change how much you print and run it again.

At 100 pages a month, the lead changes once, in month 10. After two years the gap is $210.00.

An illustration with two made-up printers so the maths is easy to check: A is $79 with $30 packs of 200 pages; B is $199 with $15 packs of 1,000 pages. Bars show what each spends in a month.

Would the answer change if you knew more?

The decision line shows how much the unknowns would have to add up to before the order reverses. Add costs to either side and watch it tip.

Brother HL-L2460DW is $71.71 lower on what we know.

At 100 pages a month for a year, the gap between known subtotals is $71.71. If Brother HL-L2460DW’s unanswered costs outgrow Epson EcoTank ET-2850’s by more than that, the order reverses.

Epson’s ink prices aren’t published, so neither total is complete. This is a break-even point, not a recommendation.

Your approval fits one purchase exactly.

A passkey approves a fingerprint of the whole review, not a spending limit. Approve it here, then try to sneak something past it.

Keep the decision, not just the receipt.

After you approve, OwnCost mints an ownership passport: the exact amount you approved, its fingerprint, the forecast you saw and the sources behind it. Change your plans later and this record stays exactly as it was.

Honest about what it knows.

A cost tool is only useful if you can tell a fact from a guess. These are the lines OwnCost holds.

What you’ll always see

  • The date and source behind every price.
  • Each cost nobody can price yet, by name.
  • Your own entries and ZIP-code tax rates, labeled as estimates.
  • Exactly which amount a passkey approves, and for how long.

What it will never claim

  • That a product is the cheapest while costs are still missing.
  • That a forecast is a bill, or that a subscription was signed up for.
  • That a test checkout is a real payment or a Visa transaction.
  • That AI calculated your totals. Code does the math; AI explains it.

Questions people ask first

Does OwnCost charge real money?

Not today. Checkout is a clearly labeled test. By default it records a local simulation with no card and no money. A Square Sandbox test mode exists and never moves real money. Direct Visa payment access isn’t connected yet.

Which products can I compare?

Six, in the US: the Brother HL-L2460DW, Epson EcoTank ET-2850 and HP OfficeJet Pro 9125e printers, and the Ring Outdoor Cam, TP-Link Tapo C120 and Wyze Cam v4 cameras. It’s a curated set with dated evidence, not a search of every store.

What does “Not priced” mean?

No reliable price was published for that item, so OwnCost leaves it unknown and out of the ranking. It is never counted as $0. You can add a price you found, and it’s labeled as your estimate.

Why passkeys?

A passkey proves it’s you with your device’s screen lock, and in OwnCost it approves one exact review: product, amount, seller and one-time billing. If anything changes, the approval no longer fits and you approve again. These are app passkeys, not bank or Visa passkeys.

What happens to my photos and voice recordings?

They’re sent to Groq for processing only when you choose Analyze or Transcribe. OwnCost doesn’t store the raw image or audio, only the facts you confirm.

Do I need an account to try it?

No. You can open the workspace right away. An account, with a passkey or email and password, lets you come back to your briefs, comparisons and passports later.

Know the price of owning it before you buy it.
