Questions
Is it really free?
Yes. 3 scans a day here, no account. Every photo you send counts, even one where Peeka cannot find a bug. The app gives you 3 more a day, free, and there a photo with no bug doesn’t count. With Peeka Pro, the app identifies up to 60 bugs a day.
What can it identify?
Insects, spiders and other small creatures — beetles, butterflies, bees, moths, dragonflies, ants, true bugs, and the things people find in kitchens and bathrooms. It does not identify bites or rashes.
How accurate is it?
In our October 2026 benchmark on 50 research-grade iNaturalist photos, the identifier named the right species 72% of the time and the right genus 76%. When Peeka is not sure, she says so: “Possible match” or “Best guess”.
What happens to my photo?
It is shrunk in your browser, sent over HTTPS to our server, and forwarded to Google’s Gemini API (Gemini 3.8 Flash, or Gemini 4 Argon as fallback) to be identified. We use the paid API tier, and under Google’s terms prompts sent through it are not used to improve Google’s products. We keep neither the photo nor the result. A hashed daily counter per network address enforces the free limit and is deleted after two days.
Is anything held back for the app?
No. Everything Peeka works out from your photo is here: the name, how sure she is, what it means for people, what she noticed and the look-alikes, plus what to do when you found it indoors. The app adds a place to keep your finds, and Ask Peeka.
Not sure? Ask a human
Peeka tells you how sure she is. On a “Possible match” or “Best guess”, a person who knows the group will beat any app, ours included. These are the places we would send you:
- BugGuide.net ↗Volunteer-curated photo archive and ID requests for insects and spiders of the United States and Canada.
- iNaturalist ↗Post an observation and the community confirms or corrects the ID. Peekabug’s seasonal data comes from its research-grade records.
- University extension offices (US)Many state extension services identify photos or samples for free. Search “insect identification” plus your state’s extension service.
