# Free shopping tools

As of October 26, 2026, Vessim has 5 free shopping tools: did you overpay? checks what you paid against every price we know; the markup calculator turns two prices into a multiple; fingerprint a photo shows the 64 bits products are matched by; the budget gate holds a budget; and the price guides show what things really cost.

## Every tool

| Tool | What it does |
| --- | --- |
| [Did you overpay?](https://www.vessim.com/overpay) | Paste the link to something you bought and what you paid. We match its photo and show every other price we know. |
| [Markup calculator](https://www.vessim.com/tools/markup-calculator) | Two prices in, the multiple and the markup out, placed on a 1× to 6× ladder. |
| [Fingerprint a photo](https://www.vessim.com/tools/fingerprint-a-photo) | Turn any photo into the 64-bit fingerprint Vessim matches products by, in your browser. |
| [Budget gate](https://www.vessim.com/tools/budget-gate) | Every lamp in the index on one price line. Drag a budget and see it treated as a suggestion, or as a gate. |
| [How much should it cost?](https://www.vessim.com/prices) | The real price range of a kind of thing: the median, the 10–90% band, by origin and by budget. |
