Photo identification

Identify a spider

Add up to three photos for a cautious identification of common North American spiders.

Upload spider photos

One to three JPEG, PNG, or WebP images, up to 10 MB each and 20 MB total. Photos are compressed before upload.

A clear, well-lit photo from above plus a side view works best.

A careful starting point

Three steps, with uncertainty kept visible.

Similar-looking spiders can be difficult to separate from a single image. The tool combines visible traits with broad location and explains why every suggestion may or may not fit.

01

Add a clear photo

Use a close, well-lit view from above without approaching or touching the spider.

02

Share broad location

An optional city or approximate location helps exclude species that are not found nearby.

03

Compare possible matches

Review what supports each candidate, what contradicts it, and when another photo is needed.

Search by what you see

Spider identification guides

Compare color with body shape, markings, web, behavior, and habitat. The guides help you collect better evidence before using the photo identifier.

Private by default, cautious by design.

Photos and the optional broad location are sent only to the identification service and its AI provider for the current request. The app does not save them.

No account is required. Results keep uncertainty visible and never present an AI suggestion as professional confirmation.
