About the project
Open Shuttlecock is a free, open-source project for reading shuttlecock feathers.

Who runs it
The project was started and is run by SP x SPORT, a sports equipment company in Australia. SP x SPORT also sells shuttlecocks.
Because of that, readings and articles recommend no brand, ours included, and no reading judges whether a shuttle is genuine.
How the reading works
The site does not train its own model. It sends your three photos to Claude, an AI model made by Anthropic, together with an open reference library of graded examples.
The reading is a tendency, not a verdict. Each line carries a confidence of high, medium or low.
Your photos
You must tick a consent box before uploading. Location data is removed. Photos that are not a shuttlecock, or that show a person, are deleted as soon as they are detected.
Photos that fail review are deleted within 30 days. Approved photos are kept and may be published under CC BY 4.0. Copies other people have already downloaded cannot be recalled.
You can ask for removal at any time with your record number.

Licences
Code is under the MIT licence. The knowledge base and data are under CC BY 4.0. Factory logos and trademarks are not open-licensed.
The repository is at github.com/kakajun123/openshuttlecock.
Where it works
Photo reading is not available in mainland China, Hong Kong or Macau for now, because the AI service it uses is not offered there. The knowledge base and questions are open everywhere.
