All components are openly available on GitHub and can be used separately as Python packages or in the user interface of our browser application. The web application is hosted at . As all the source code has been published under a permissive licence along with the documentation, users can easily modify and redistribute it or integrate it into their own applications. The Python packages are all hosted on PyPI and are designed to be installable and usable with few lines of code. The DECIMER.ai web application can easily be deployed and scaled. As DECIMER is trained on publicly available data and is made available to the public in the form of a ready-to-use open-source tool, we believe that the system will significantly reduce the workload and produce high-quality data for the research community and those who are developing and curating chemical databases.
