This certainly sounds like an excellent add-on. Does anyone know if there is a similar add-on or function to scan directly from twain scanners or cameras? That is the 1 missing function in my humble opinion.

Very best wishes,

Hi, Simone,

This is n excellent piece of work! I have just tried the add-on with a bank statement in bitmap form file in my Downloads folder. It works like a dream!
Yesterday, I tried to read the same file by using NVDA + r to OCR the Adobe screen displaying the statement. This gave me only a partial read of the contents. I am sure this was limited by the way Adobe was displaying the image.

Just now, I pointed to the closed file in my downloads folder and press NVDA+shift+r and, almost instantly, a crisp, clear version of the statement page appeared without all the material that complicated the Adobe-based image.

Many thanks to you and to the developer team and for sharing this great tool!

All the best,

Subject: [nvda] new addon: NVDA Advanced OCR.


I am part of a developer team of a new addon.

I'd like to inform you that yesterday  we published the first version of Nao, NVDA Advanced OCR.

I paste the little readme file and at last I put the link for download.

Feedback and suggestions are welcome!

Nao is an addon that improves the standard OCR capabilities that NVDA provides on modern Windows versions. While NVDA standard command uses Windows OCR to recognize the screen, NAO is able to make the OCR on files saved on your hard drive or USB devices. Use NVDA-Shift-R to recognize any sorts of images and pdf! Simply put the focus / cursor on the file you desire, don't open it, but hit NVDA-Shift-r. The document will be recognized and a simple text editfield will appear, allowing you to read the entire content. Nao is able to handle also multipage pdf, so if you have a not accessible document, don't worry, Windows OCR will be able to make yhr entire work.

System Requirements
The addon works on Windows 10 and Windows 11 systems, since they have OCR capabilities builtin. Nao is compatible from NVDA version 2021.2, so don't use older versions of the screen reader. Note that Nao works with Windows Explorer, on desktop, or with Total Commander filemanager; don't use other software like 7zip or Winrar , since they are not supported.

Features and commands
• NVDA + Shift + R: recognize any sorts of images and pdf from file system; ◦ PgUp / PgDown: move the cursor between real pages of a multipages document.
◦ NVDA + Shift + P: report page number related to the cursor position, in a multipage document.
• NVDA + Shift + Ctrl + R: take a full screen shot and recognize it.
