If you want an app that'll help you identify plants with a photo, PictureThis is a great option. The app uses AI-powered instant identification to diagnose plant diseases, suggest treatment and offer advice on watering, lighting and feeding. It's got more than 20,000 plant species covered, with a free version and premium subscription option.
Another good option is Pl@ntNet, a citizen science project that uses AI to help you identify plants while also helping preserve biodiversity. The app offers offline identification, GeoPl@ntNet for local species, and microprojects for specific regional or plant type projects. It's designed to be easy to use, and there are opportunities to get involved with the community.
You could also try Google Lens, a built-in feature that spans Google apps. It uses your phone's camera to visually search and identify plants, among other things. Its ability to work across devices and be integrated with multiple apps makes it a good option for quick plant identification.
For a broader perspective, Picurious also offers AI-based image analysis that can identify plant species, along with other subjects like art and architecture. The app encourages you to learn more by asking follow-up questions based on the uploaded photo, so it's good for educational and curious uses.
