LEADTOOLS provides fast and accurate Intelligent Character Recognition SDK technology for .NET (C# & VB) and C/C++ developers. Leverage the high-level LEADTOOLS ICR toolkit to rapidly develop robust, high-performance recognition applications that incorporate features and benefits such as saving time and money over manual data entry by extracting hand-written text from scanned documents, and converting images to text-searchable formats such as PDF, PDF/A, and Microsoft Word.
