IronOCR Roadmap

We developed IronOCR to fill a market need and it’s excelled as one of our leading products. Today we are continually shipping new feature requests, driven by community demand.

We actively work with Google’s latest Tesseract technology to drive stability and high accuracy. This ensures our customers are benefiting from the cutting edge OCR reading engine.

Our monthly releases see IronOCR continually prove its worth, and drive our mission to help end users move the .NET language forward.

We know IronOCR is one of the top choices developers make¹. To cement IronOCR as the leading product of its kind we are applying the latest technology to improve image filters, computer vision and machine learning.

Our next epic will be to launch IronOCR for multiple programming languages.
