Frequently asked questions
How accurate is Kagn's arachnid identification?
Kagn uses Gemini-class AI for identification, cross-checked against the World Arachnids pack of 1,055 species. Accuracy is typically very high for clear photos of common species, with confidence scores and alternative matches shown for ambiguous cases.
Does Kagn work offline?
Yes — Kagn is an offline-first app. Open the pack while you have a connection and it keeps working in the field: log sightings offline, save unknowns with their photos, and Kagn identifies them when you reconnect.
What species does the World Arachnids pack cover?
1,055 species worldwide, and the pack grows automatically as new species are confirmed.
Is Kagn free?
Yes. The free tier includes AI identification, lifelist tracking, trips, and the community. Kagn Plus removes the weekly identification limit.
