Spidentity

Spidentity uses Claude's vision capability to identify spiders from your photographs, with particular focus on species native to the British Isles, alongside the occasional foreign visitor that arrives on imported goods or in shipping containers.

Your guide is Webster, a European garden spider who lives in the corner of the porch. He's spent a lot of time observing his cousins and has notes on most of them. He's a touch shy but will wave from his web. For deeper reading, see the Spidipedia.

For researchers and serious recorders. The sightings log is built to capture proper field data: GPS coordinates (one tap), date, sex, life stage, body length, count, and habitat type. You can export the lot as Darwin Core flavoured CSV for upload to iNaturalist or the British Arachnological Society's Spider Recording Scheme, or as JSON for any other downstream use.

On offline use. The Spidipedia, your records, and your sightings work fully offline once the app is installed (the service worker caches everything). Logging sightings works offline too — they save locally. The one part that needs the network is the photo identification itself, since that runs on Claude's servers. When you're offline, the app tells you so, and you can still log a sighting with whatever you saw and identify it later when you have signal.

On accuracy. No automated identifier is infallible. For specimens of medical or ecological concern, defer to a qualified arachnologist — the British Arachnological Society maintains the authoritative record.

On safety. The vast majority of British spiders are harmless to humans. Bites are exceedingly rare and most produce nothing worse than a nettle sting. If you experience unusual symptoms after a suspected bite, consult a medical professional.

On privacy. Your photographs are sent only to the identification service. Records and sightings are stored locally on this device and never uploaded.
