Review::Transkribus is a web-based platform supporting transcription of historical documents for researchers, students, and communities. The platform is part of a suite of tools developed by read-coop to support the digitization workflow from scanning through to transcription and sharing. Trankribus' automated transcription, with manual editing abilities, handles both handwritten and printed documents through processes known as handwritten text recognition (HTR) and optical character recognition (OCR). To support a range of mostly Western languages, scripts, and penmanship styles, Trankribus offers free and paid models and enables its users to train their own custom models. This last feature sets it apart from other historically-oriented HTR and OCR tools. An API is available for developers wanting to integrate Transkribus into their own environments.
