Measure plants in photos: leaf area and more, from a phone or from your code.

Website · Platform · Research · Blog · LinkedIn · X · YouTube

Send a photo of leaves on the calibration pad and get back each leaf, its outline and its area in cm². Run a workflow, such as Leaf area, for measurements with their units, or a single model, such as the leaf detector, for what it finds in the request. Everything the platform does is an API call: the same one from the platform app, a script or a phone.

Access is by invitation for now: ask for access.

Starters: small, complete apps on the Petiole API to copy and build on, under the MIT licence. Each takes your API key, sends a photo and shows what came back, drawn on it. Model predictions and workflows, for the web, Python, mobile and desktop. The first, petiole-starter-react-predictions, is on its way.

SDKs for Python and TypeScript follow.

Petiole's measurements are used in plant science, and the papers that used them are on petiole.pro/research.
