High-quality data labeling for documents and content - from digitization of archives to reporting, advertisement, content moderation, and more.

Expert Labeling
of Document Data

Document Annotation services for a wide range of computer vision applications.
Document Annotation services

We employ in-house teams to help you annotate a variety of documents, such as invoices, cheques, bills, and even newspapers and magazines. All paper documents are different. If you need to train your computer vision model to read them all, we are here to help.

This doesn’t just apply to paper - computer vision can learn to read text in different environments such as billboards, license plates, road signs, and so on. Any company that trains AI for real-world applications can benefit from accurate document annotation.

01. Every Part of a Document Matters


Top, bottom, columns, lines, and tables. We annotate different parts of a document to match your needs. This process makes it easier for your CV model to recognize the issuer, amount that needs to be paid, taxes, due date, or other relevant details.

It’s all about numbers. Teach your model to differentiate between phone numbers, dates, hours, item quantities, and financial figures.

02. Newspapers and Magazines

Newspapers and Magazines

Even the most advanced applications get confused when trying to process newspapers, especially older editions. This is due to columns of text being mixed with vintage advertising and pictures.

With our annotation services, you can teach your software to navigate spreads and columns in proper order so it won’t be confused with enormous amounts of poorly structured text data.

03. Digitizing Archives

Digitizing Archives

Even today, libraries are filled with an enormous amount of content waiting to be digitized for online release. This isn’t just a matter of archives - some organizations still use paper to keep track of important data and never bother to streamline it.

Keymakr can help teach AI to digitize data instead of humans - automatically going through archives with the help of computer vision and quickly uploading results to the cloud.

04. Real-World AI Applications

Real-World AI Applications

Computer vision systems don’t just get fed receipts for processing anymore - we have actual robotics systems designed to function in the real world. Teaching your robot cashier or assistant to read paper documents is crucial for sophisticated next-generation systems.

These datasets require human context and annotation before our AI learns to tell the difference between a glossy journal and a medical paper. With us, you can make any CV system a reality!
