What are the best OCR software solutions in 2024?

Optical character recognition or OCR software is most commonly used to digitize files and digitally archive paper documents. OCR applications convert non-editable document formats such as PDFs or images to machine-readable formats that are both editable & searchable. 

Today, it’s much more than just that. With AI and machine learning, modern OCR software can even automate end-to-end data capture workflows for a wide range of business documents.

But here’s the challenge: with so many options out there, how do you find the best OCR software for your specific needs? Don’t worry—we’ve got you covered.

In this article, we have rounded up the leading OCR applications for a select list of popular use cases (handwriting recognition, accounts payables, etc.) and document types (invoices, receipts, bank statements, etc.).

Let's help you find the perfect fit!

What is OCR?

OCR or Optical Character Recognition is a technology that identifies & recognizes text within scanned documents, photos or images. OCR technology powers tools that can extract data from PDFs or scanned documents by converting it into machine-readable text/data that can be edited, displayed, searched electronically & stored more conveniently for further processing. There are tools available online, such as the Online OCR tool, that facilitate this conversion seamlessly.

Over the years, OCR has been increasingly adopted in many document-processing workflows that previously depended on manual data entry. OCR is used to extract data from all types of documents and send it to other business applications for further processing. Here's a deep dive into how optical character recognition works.

A brief history of OCR

In the early 1970s, Ray Kurzweil founded Kurzweil Computer Products, Inc., whose OCR product could recognize text printed in any font. He quickly realized that the best application for this technology would be a text-to-speech reading machine for the visually challenged. Later, in the 1990s, OCR was extensively used to digitize historical newspapers and legal documents. 

Today OCR applications and products powered by AI & machine learning are available online and as APIs that can integrate seamlessly with other applications - e.g. Tesseract OCR, Google Vision and Nanonets.

They are used for automated data entry, pattern recognition,  text-to-speech services, indexing documents for search engines, cognitive computing, text mining, and machine translation among various other applications.

Why is OCR software important for businesses?

While organizations are striving to turn paperless and automate business workflows, a large portion of business communication is still done through paper documents, PDFs or scanned files.

How to choose the best OCR software for your use case?

If you're reading this section, I'm assuming that your use case hasn't been covered in any of the categories above or you have already checked out our OCR software recommendations and are looking for an alternative.

If you are looking for an alternative OCR software to any of our recommendations, we would strongly suggest that you benchmark any alternatives you check out against our recommendations in that particular category. Compare any OCR software alternatives of your choice against our recommendations on review platforms like G2 or Capterra.

Or just talk to us to get a fair assessment and your best options forward.

If your use case hasn't been covered in our list above, here's a checklist to help you come to make a decision:

• Check if software review sites like G2, Capterra or Gartner curate software for your category (e.g. spend management, medical coding, order processing).
• Next check out the comparative matrix, if any, published for that category - essentially comparing all software across key performance indicators.
• Shortlist those that mention data extraction, OCR, data capture etc. as a key feature.
• Or shortlist by ability to integrate with specific software - e.g. EHR software for medical coding/billing, or WMS applications for order processing workflows.
• If you have a very specific budget or at least a range, filter out all the OCR software or applications with OCR features that exceed that figure.
  • If information on pricing isn't public, just drop a message to the respective sales team along with your budget details. If your budget matches their price points - you'll be sure to hear back from them. If not, you're probably not a right fit for that OCR service with respect pricing or use case.
• Negotiate a POC-type engagement with all the OCR software that you have filtered to this stage. If a provider is unwilling to do a POC - share the list of competitors/alternatives that have agreed to do a POC or negotiate at least for a paid POC.
• Once the POC is set up simultaneously test each software across a common sample of documents and try to integrate with ERPs and business software that are pertinent to your particular use case.

At the end of the POC period you should have a clear understanding of the following:

• The OCR software or applications with the highest accuracy rates, or with the fastest data extraction rates. Accuracy rates reported by OCR applications on their websites are more often than not simply marketing fluff.
• The extent, quality and nature of support that the OCR vendor can offer.
• The technical expertise required in-house to manage the OCR solution moving forward.
• The amount of documentation available to maintain the solution as well as the performance attained during the POC.

How we test or benchmark against other OCR applications

For all practical purposes we can't really test ALL the OCR software out there. So we restrict ourselves to a maximum of 30 software to serve as our consideration set each time we do this exercise - this includes the 17 software featured in the list above.

We maintain a comprehensive sample data set containing over 200+ varied documents such as invoices, receipts, bank statements, ID cards, medical prescriptions, material safety data sheets, different kinds of forms and reports etc. Each of these sample documents either tie back to a popular use case such as accounts payable or mortgage processing or popular document types such as invoices or receipts.

We then put our consideration set of OCR software to test on the entire data set mentioned above and record the output. Confidence scores are typically assigned to each output. A round of human review is done to compare actual OCR output against expected/ideal results. We assign scores for OCR accuracy, data extraction throughput, and processing time.

Broadly this is the methodology followed to measure/benchmark the OCR software listed above. While we do this exercise most regularly (every month) for the accounts payable use case, and document such as invoices and receipts specifically - we cover all 30 OCR software in the consideration set every 3-6 months.

And here's why this list is unbiased, dependable, and based on real-world OCR expertise:
