How to What Is This App? AI
Follow these simple steps to get instant AI-powered identification
Take a clear photo of whatever you want to identify — a plant, insect, rock, household object, animal, or anything else that's caught your curiosity. You can upload directly from your phone, tablet, or desktop computer without downloading any app. Simply visit IdentifyThis.app in your browser, sign in with Google, and select your image.
Our advanced AI examines your image in seconds, analyzing shapes, colors, textures, patterns, and contextual details to determine what you're looking at. Unlike tools that simply return a label, our AI considers multiple identification possibilities and cross-references a vast knowledge base covering thousands of species, objects, and categories. The analysis is thorough yet fast, giving you confidence in the result.
You'll receive a rich, contextual identification result that goes beyond just a name — including key characteristics, interesting facts, safety information where relevant, and related details that help you truly understand what you've found. Results are presented clearly on any device, and you can ask follow-up questions to dig even deeper. One free identification is included, with unlimited identifications available on our affordable plans.
Alternative Methods
Field Guides & Reference Books
Traditional printed field guides for plants, birds, mushrooms, and insects offer authoritative identification help but require you to own the right book for your region and category. They work offline but can be slow, require experience to use effectively, and don't cover every possible subject in one place.
Expert Communities & Forums
Online communities like Reddit's r/whatsthisbug or r/whatsthisplant let you post photos and get answers from knowledgeable enthusiasts and professionals. This method can yield highly accurate results but may take hours or days to receive a response, making it less practical for time-sensitive situations.
Local Naturalist Groups & Nature Walks
Joining a local naturalist group or guided nature walk connects you with experts who can identify things in person and explain their reasoning. This is a rich learning experience but is limited by geography, availability, and the specific expertise of group members present.
University Extension Services
Many universities offer plant, pest, and agricultural identification services where you can submit photos or samples for expert review. These services are authoritative but often slow, regionally limited, and primarily focused on agricultural or invasive species rather than general curiosity.
Photo Quality Tips
- ✓Use natural daylight whenever possible — avoid harsh direct sunlight or deep shadows that can distort colors and textures.
- ✓Get as close as reasonably safe to fill the frame with your subject, ensuring fine details like leaf veins, wing patterns, or surface textures are clearly visible.
- ✓Hold your camera steady or brace against a surface to avoid motion blur, especially for small subjects like insects or coins.
- ✓Capture multiple angles if you're unsure — a top view, side view, and any distinctive markings help the AI make a more confident identification.
Best Practices
- •Include a common object like a coin or hand for scale when photographing rocks, fungi, insects, or small objects.
- •Use a plain, contrasting background where possible — placing a leaf or insect on a white piece of paper can dramatically improve identification accuracy.
- •For plants, photograph both the leaves and any flowers, fruit, or bark visible, as each detail can be a crucial identifying feature.
- •Avoid heavy filters, cropping too aggressively, or over-editing the image before uploading, as this can remove color and texture information the AI relies on.

Why Choose Our Identification Service?
The most accurate, fast, and privacy-focused identification tool available online.
IdentifyThis.app runs entirely in your browser, meaning you never need to download, install, or update an app on your device. It works seamlessly on iOS, Android, Windows, Mac, and Chromebook — any device with a modern browser.
Instead of downloading a separate app for plants, another for insects, and another for rocks, IdentifyThis.app handles all categories in a single unified tool. Whether you find a mushroom, a spider, an old coin, or an unknown plant on the same walk, one tool covers it all.
Get one free identification to try the tool, then unlock unlimited identifications for just $3/week or $10/month. Compare that to PictureThis at $39.99/year (~$2.50/month) or PlantID at $19.99/year — our weekly plan is perfect for casual users while the monthly plan is significantly cheaper than most dedicated apps.

Your uploaded images are used solely for identification and are not stored, sold, or used to train models in ways that compromise your privacy. In a world where many free apps monetize your data, IdentifyThis.app keeps your curiosity private.
Whether you're on a flagship smartphone or an older laptop, IdentifyThis.app is optimized to deliver fast, clear results across all screen sizes and device capabilities. No minimum hardware requirements, no OS version lock-in — just open a browser and identify.
