Count nails from a photo

Spread the nails one layer deep on a tray or flat surface and photograph from directly above — every one gets a dot for verification. Built for factories, fastener suppliers and maintenance stores — add each photo to the tally sheet and export the whole count as a CSV or PDF report.

常见问题

Do the items need to be separated before counting?
Slight touching is fine — the density engine keeps touching items apart. Avoid full overlaps (items on top of items): spread them one layer deep under even light for an exact count.
What if the photo has more than just nails in it?
Mark 1–3 example nails by dragging a box around them and the AI counts exactly that item, ignoring everything else in the frame. Every counted item gets a dot on the image so you can verify the total at a glance.
我可以把好几张照片合计成一个总数吗?
Yes — every count can be added to the tally sheet as a labelled row, or use Bulk audit to upload many photos at once. Export the result as a CSV, generate a PDF report, or save the stock-take to your account and share a read-only link with your team.
免费吗?是否私密?
Yes — counting photos is free with no signup for everyday use. Photos are uploaded only to process and are deleted automatically afterwards; we never keep or share them.

How Object Counter helps you get it done

Real problems it solves every day — for businesses, creators, and everyday tasks. Find the use case that fits you and start in seconds.

For Business

Warehouse Cycle Counts Without Recounting

Switch to Bulk audit, photograph every shelf or bay in one pass, and get a grand total plus a per-shelf tally row automatically — a full cycle count in minutes instead of a walk-around with a clipboard.

For E-commerce

Small-Parts Inventory for Makers & Etsy Sellers

Mark 1–3 example beads, screws or components so the counter ignores packaging and background clutter, then track restock levels for each product line in the tally sheet.

Education

Classroom & Lab Supply Counts

Count dice, counters, test tubes or lab kits from one photo instead of counting by hand, then export the totals as a CSV for supply reorders.

Productivity

Shareable Stock-Take Reports for Teams

Save a completed stock-take to your account, generate a branded PDF report, and share a read-only link so managers or teammates can review the count without re-uploading anything.

For Developers

已包装成品的批量质检计数

Mark one example unit and switch to Similar items mode to verify the exact piece count in a packed finished-goods box or tray before it ships — the mode built for parts that touch or overlap, unlike a mixed-scene detector — catching an under-count before a customer does.

Personal Use

Hobby Collection Counts for LEGO, Trading Cards & Models

Mark one example piece and get an exact count of a large LEGO, trading-card or die-cast model collection from a single photo, instead of manually sorting and counting hundreds of pieces by hand.
