comprehensive Annotation tool

Annotate any type of documents whether its PDF, images or text.

Extract text from images with unparalleled accuracy. Our Optical Character Recognition (OCR) technology ensures that no detail goes unnoticed, making data extraction a breeze.

“Unlike most other text annotation tools, UBIAI enables to annotate native and scanned PDF thanks to their OCR, and the coordinates of the bounding boxes for each word are available (which could be useful). 

Moreover, the User Interface is good, UBIAI is very attentive to user feedback and needs, and there is a discount for students/researchers. For a startup that was recently created, I think they have potential!”
