You can identify most plants and birds by pointing your phone camera at them and using a free AI app. Google Lens (already on most Android phones) and Seek by iNaturalist are great for plants. Merlin by Cornell Lab is the best free bird identifier. Most identifications take under 10 seconds.
You're walking in a park and spot a flower you've never seen before. Or a bird lands nearby and you have no idea what it is. A few years ago, finding out would mean buying a field guide. Now you just point your phone at it.
AI identification tools have gotten surprisingly good. Here's how to use them — starting with what's already on your phone.
The Apps Worth Knowing
Before the step-by-step, a quick overview of the main options:
- Google Lens — built into most Android cameras and the Google app on iPhone. Best starting point because you probably already have it. Identifies plants, flowers, and trees well.
- Seek by iNaturalist — free app from the California Academy of Sciences and National Geographic. Shows a confidence meter as you point your camera. Great for beginners because it shows you the genus even when it can't nail the exact species. Privacy-friendly: doesn't require an account.
- Picture This — app focused specifically on plants. More detailed care and toxicity information than Google Lens. Free version has daily limits; paid version is more capable.
- Merlin Bird ID (Cornell Lab of Ornithology) — free, excellent, and the most trusted bird identification app available. Works by photo or by sound.
Try Google Lens first — it's already on your phone
On Android: Open your camera app and look for a Lens icon (a small square with a circle inside) in the corner. Tap it, point at the plant, and Lens shows identification results in real time.
On iPhone: Open the Google app (download it free if you don't have it), tap the Lens icon in the search bar, then point at the plant.
Lens shows you its best guess with a confidence level and usually links to more information. For common garden plants, flowers, and trees in your yard, it's often all you need.
Use Seek for a more nature-focused identification
Download Seek from the App Store or Google Play (free, no account required). Open it and tap the camera icon.
Point your phone slowly at the plant. Seek shows a real-time readout — first a broad category (flowering plant, insect, bird), then narrowing down as it gets more confident. When it's confident enough, it shows the full species name.
Seek also shows an "evidence" indicator — how many observations of that species have been reported near your location. If thousands of people have logged that species nearby, you can be more confident.
Tip: Move slowly, keep the subject in good light, and try to get the whole plant or leaf clearly in frame.
Identify birds by sight or sound with Merlin
Download Merlin Bird ID (free). The first time you open it, set your location so it knows which birds live in your area.
By photo: Tap Photo ID, upload a photo or take one now. Merlin asks a few quick questions (size, main color, behavior) and then shows you the top matches with photos for comparison.
By sound: This is the most impressive feature. Tap Sound ID, tap the microphone, and hold your phone toward a bird you can hear. Merlin lists the species it hears in real time — often multiple species at once if several birds are calling. You can see exactly which sound triggered each identification.
For backyard birds, feeders, parks, or a nature walk, Merlin is remarkably accurate.
Ask ChatGPT follow-up questions
Once you have a species name, ChatGPT is great for learning more. You can take a screenshot of the identification and upload it, or just type the species name. Good follow-up questions:
I just identified a black-eyed Susan (Rudbeckia hirta) in my yard.
Is it native to the eastern United States? Does it attract butterflies?
Can I eat any part of it?
I saw a red-tailed hawk in suburban Ohio.
What does it eat? Is it common year-round or does it migrate?
How do I tell it apart from a Cooper's hawk?
ChatGPT can explain things at whatever level you want — ask it to "explain this like I'm a complete beginner" if you want a simpler answer.
Log your sightings (optional but rewarding)
Both Seek and Merlin let you save the species you identify to a personal log. Seek contributes your observations (anonymously if you don't have an account) to iNaturalist, a global database used by scientists.
Over time, your log becomes a record of what you've seen — which birds visit your yard in winter, which wildflowers bloom along your usual walking path. Some people find this unexpectedly satisfying.
You can also upload your observations to iNaturalist's full website for more detailed information and to have the identification confirmed by the community.
A Safety Note for Plants
AI identification is good, but not infallible. For plants:
- Never eat anything based solely on an app ID, especially mushrooms or wild berries
- If a child has touched or eaten an unknown plant, contact poison control — don't rely on an app
- For plants you want to eat or use medicinally, confirm with a local expert or a trusted field guide
For casual curiosity — identifying what's growing in your garden or along a trail — the apps are great. For anything with safety implications, add a second opinion.
What to try next
Now that you've seen how AI can answer nature questions from a photo, it's worth knowing what else you can ask ChatGPT by just describing what you found. The guide to useful things to ask ChatGPT has many practical examples that go well beyond plant and bird questions.
