From the site: "Transkribus is a comprehensive platform for the digitisation, AI-powered recognition, transcription and searching of historical documents. Transkribus can be trained to recognize exactly the documents you are interested in: Arabic, or English, Old German or Polish, Bangla, Hebrew or Dutch."
Most of the features they offer are at no charge, but a subscription service is available as well, which adds a few bonuses such as larger amounts of storage and text recognition.
