Any price on any site, in your currency

PriceLens reads the prices already on a page and converts them into the currencies you choose — as a card on hover, or written in place next to the original. No copying, no switching tabs, no calculator.

Shopping across borders means doing arithmetic in your head on every page. PriceLens does it where the price already is, in the currencies you actually think in.

What It Looks Like

The same page, with and without the arithmetic.

A shopping page where each price carries its converted value beside it
Inline mode writes the conversion next to every price on the page.
A card showing one price converted into four currencies with a 30-day chart
Hover a price for every currency you picked, and a 30-day chart of the pair.
The PriceLens settings popup with currencies selected
Pick up to five currencies, and which one is written inline.

Built for How Shops Actually Write Prices

Most converters handle the tidy cases. The web is not tidy.

Reads prices as shops write them

Every format a real storefront uses, not just the tidy ones.

  • €49,99 · 49,99 € · 1 299 kr · RM 89.90
  • 250 USD · USD 89.50 · 49 dollars
  • 1,234.56 · 1.234,56 · 1 234,56

Finds split prices

Large shops draw the pounds and the pence in separate elements. PriceLens reads them as one price.

  • Whole and fraction in different tags
  • Symbols in their own element
  • Never a 100× mistake

Knows what “$” means here

It reads the shop’s own declared currency before falling back to your preference.

  • Structured data and Open Graph tags
  • Domain and page language
  • A Canadian shop is not read as US dollars

Two ways to see it

A card on hover, or the conversion written in place next to the original.

  • Hover card with every currency you picked
  • Inline mode for a whole page at a glance
  • Alt + Shift + I switches

Built for actual spending

The mid-market number is not what leaves your account.

  • Add your card’s FX markup
  • Click a row to copy the amount
  • 30-day chart of the pair

Private by construction

No account, no tracking, no analytics, no ads.

  • Pages are read in your browser only
  • Nothing about a page leaves your device
  • Rates cached locally, works offline

Three Steps, Then Forget About It

1

Pick your currencies

Open the popup and choose up to five, and which one gets written next to the price in inline mode.

2

Browse as usual

PriceLens finds the prices on each page you open, whatever format the shop writes them in.

3

Hover, or read in place

A card on hover shows every currency and a 30-day chart. Inline mode writes one conversion beside each price.

Frequently Asked Questions

Is PriceLens free?
Yes. It is free, has no account, and shows no ads.
Which currencies does it handle?
Around 150, and optional crypto (BTC, ETH and friends) behind a permission you grant yourself. You pick up to five to see at a time.
Where do the rates come from?
ExchangeRate-API and Frankfurter, which publishes data from central banks including the European Central Bank. They are indicative mid-market rates for shopping, refreshed twice a day — not trading quotes.
Does it work offline?
Yes, on the rates it last fetched. They are cached on your device, so conversions keep working until the next refresh.
Why does it need to read the pages I visit?
A price can be on any site, so the extension has to look at the text of the page you are on. It looks for prices and nothing else, and nothing about the page ever leaves your browser. The privacy policy spells this out.
A price on a site is not converted.
Some shops draw prices as images, or inside a closed shadow root no extension can see. If the price is ordinary text, send us the page address — it is usually a format we have not taught it yet.
How do I turn it off on one site?
Open the popup on that site and use the “This site” switch. Alt + Shift + P turns the whole extension off and on.

Something Not Converting?

A page address and a screenshot are usually enough for us to fix it.
