Catalogue your LEGO collection without typing every set name by hand.

No. ClearBench bundles a downloaded copy of the Rebrickable database. The first time you open a LEGO collection you'll be asked once whether to install it; from then on every set-number lookup runs locally against the file on your computer. The set number you typed never leaves your machine. The reference database file lives at a path you can inspect and delete any time from Settings.

Type the set number into the first field of a new item and tab out, and the lookup fills the set name, theme, year released, piece count, and minifigure count from your local copy of the Rebrickable database. You can edit anything afterwards. Subtheme, variant, and any condition or acquisition details are yours to type because they're specific to your copy of the set, not the design.

No. Image downloads are per-set and opt-in. The first time you want to see the official image for a set, you click a button on that item's page and ClearBench fetches it once from Rebrickable's CDN, caches it locally, and never asks again. Your library doesn't pre-cache thousands of images you'll never look at, and the lookup carries only the public set number, nothing about your copy.

Every LEGO item carries a status field with the build states collectors actually use: Built, Sealed, Partially built, Parted out, and On display. The set condition is its own field (Mint / Near mint / Excellent / Good / Fair / Poor), and the box and instruction manual have separate condition fields with their own scale (Mint / Near mint / Light wear / Heavy wear / Damaged / Opened & resealed) because paper goods age differently from bricks. There are flags for whether you have the original box, whether you have the manual, and whether you display it lit (LED kit installed).

Yes. Each LEGO item has Estimated value, Valuation date, and Valuation source on the Valuation tab, plus acquisition cost on the Details tab. A collection report PDF lists every set with its identity, condition, current value, and a label preview, the document insurers ask for, generated on your computer without anything leaving it.

The print composer renders an A4 sheet with a 4×7 grid (28 labels at 50×40mm), centred with margins to match the most common cabinet-label sheet sizes. PDF output is exact-size; what you see on screen is what comes out of the printer. Custom sheet sizes for non-Avery formats are on the roadmap.

Database updates are user-initiated. From Settings → Reference data you can check for an update, see how big the new version is, and download it. ClearBench will never silently re-download a multi-megabyte file in the background. If a set hasn't been catalogued yet (a brand-new release the snapshot doesn't know about), you can still create the item: you just type the fields yourself and re-run the lookup later when the next snapshot ships.
