• Do you plan to release Prizmo Go for other mobile phones?
    Creaceed is specialized in Mac and iPhone development. We started over 12 years ago to work with all Mac-related technologies (Cocoa, Objective-C, OpenGL...), and we think they are great. So, we want to go on this way. We have no plan for an Android version at this time.

  • Is Prizmo Go also available on computers?
    There is a Prizmo version for Mac available on computers supporting OS X 10.10 or higher. More information here.

Supported Devices

  • Will Prizmo Go work with my iPad?
    Yes, it will. Prizmo Go is a universal iOS application, working on both iPhone and iPad. However, Prizmo Go will only work on devices running iOS 10 or later (starting from iPhone 5 and iPad 4th Generation).

  • Can I use Prizmo Go on iPod touch?
    Yes, if you have an iPod touch running iOS 10 or later.


  • Can I process multipage documents?
    No, that is not possible with Prizmo Go which only recognizes one document at a time. Multipage document scanning is possible with the standard version of Prizmo. More information here.


  • Which export options are available?
    Prizmo Go allows to export the recognized text using iOS built-in Share sheet. There is also a quick "Copy to clipboard" shortcut.
    Note that Prizmo Go supports the Universal Clipboard (requires a Mac running macOS Sierra that is compatible with Universal Clipboard).

  • Which Cloud storage services can I export to?
    You can send the recognized text to any service supporting iOS standard share sheet. Here are a few examples of these applications: Dropbox, Evernote, Google Drive,…

  • Can I export documents in PDF?
    No, Prizmo Go only interacts with the text and there is therefore no document created. If that's what you need, please refer to the standard version of Prizmo.

Optical Character Recognition (OCR)

  • I tried Prizmo Go's OCR but I got poor results. What can I do?
    The accuracy of the OCR engine in the available languages has been checked. Even with pictures taken in poor circumstances (document over several other documents, picture taken in front of the document rather than above…), we got pretty good results.

    Here are some recommendations for improved OCR results:
    • make sure the picture you've taken is not blurry, as this decreases OCR accuracy.
    • you should be right above the document you want to photograph.
    • use the camera flash when you take a picture.
    • choose the accurate language of the document you in the list.(*)
    • try using the Cloud OCR as it is usually more accurate than the built-in OCR.

    (*) The Cloud OCR will automatically recognize the language, there is no upfront language selection to do.

  • Is the quality of my images good enough to perform OCR?
    Image quality is a major issue indeed. OCR results will most likely be disappointing if the input image quality is poor. Here are a few examples of what should be avoided:

    • The image is blurry. Check you are able to read the text on the picture. You can't in this example. Please take a new picture of better quality.

      Example of what should be avoided for processing with Prizmo: a blurry shot

    • The ticket is crumbled.

      Example of what should be avoided for processing with Prizmo: crumbled paper

    • It is a double-sided document. Characters, lines and colors which are printed on the other side could hinder OCR.

      Example of what should be avoided for processing with Prizmo: a double-sided ticket

  • When to use the Cloud OCR?
    Cloud OCR provides improved accuracy and also handles more languages. Cloud OCR requires an internet connection to run and the purchase of Cloud OCR units (each request to the service consumes one unit).

    Languages available: Arabic, Chinese (Simplified), Chinese (Traditional), Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Norwegian Bokmål, Polish, Portuguese, Russian, Spanish, Swedish, Turkish.


    • Cloud OCR 100-Pack: 1,09 € - $0.99

    • Cloud OCR 1000-Pack: 5,49 € - $4.99

    Note that there is a 10-Pack Trial that can be activated once within the app for testing purpose.

  • Are you going to add new languages for OCR?
    Yes, we would like to support additional languages, but we are limited by the OCR library we use. If more languages become available, we will certainly add them to the list.

  • Is OCR performed on the iPhone itself or on your servers?
    When you use the built-in OCR, the images are only processed locally on your device unlike the Cloud OCR where the images are sent to the Cloud service of Microsoft that sends us back the recognized text (a link to Microsoft's Privacy Statement can be found within the app ).

  • Can Prizmo Go recognize handwritten notes?
    No, Prizmo Go’s built-in OCR engine is only for typewritten texts and documents. There’s currently no reliable OCR engine for handwriting (remember sometimes it’s even difficult to read someone else’s handwriting, and our brain is a much more powerful engine than any OCR technology).

  • Can I recognize text from a screen?
    Prizmo Go's OCR, as most OCRs on the market, only works with printed text and not text from a computer screen. It all depends on the pixels visible in the photo you took. It might work better on retina displays and if the Cloud OCR is activated, but even then results won't be as accurate as they are with a printed document.
    Using a screenshot of the iPhone/iPad screen that is made on the device itself (using the Home and Lock buttons) is supported, and typically leads to good results on devices with Retina displays.

Text-to-Speech (TTS)

  • Are there other voices available?
    You can download enhanced variant of voices by going to iOS Settings > General > Accessibility > Speech > Voices.

  • Can I modify the reader's speaking rate?
    Of course. When you are in Text-to-Speech mode, tap on “1x” (which is the regular speed) at the lower right corner and adjust the speaking rate to your liking.


  • I am a blind iPhone user. Can you tell me if Prizmo Go works with the VoiceOver screenreader on the iPhone?
    Yes, the app fully supports VoiceOver with an improved workflow for visually impaired and blind users. Prizmo Go also used specific image processing to handle unaligned text and reversed configurations. Thanks to VoiceOver, you can have a spoken guidance prior to shooting which will help you to take the best picture possible for recognition. There is a deep integration with Dynamic Type for improved and customisable text appearance.

  • I would like the text that has been recognized by Prizmo Go to be read aloud directly after I take the picture. Is that possible?
    Of course, all you need to do is go to the app’s settings and activate “Read Text Automatically”. That way every time you take a picture, Prizmo Go will OCR the text and read it aloud immediately.


  • Is it possible to invoke Prizmo Go from another app?
    Yes, Prizmo Go can be invoked from other apps to perform a text recognition. This is handled with a custom URL scheme. Go to Settings > Automation for the documentation.


  • I'd like to scan passages from my French textbook but it doesn't work properly. What can I do?
    Before taking the picture, make sure to choose the right OCR language. Tap the button in the upper right corner of the camera view, and select the language in the list.
    If it is a language that is supported by the Cloud OCR and not the built-in one, then just tap on ‘Cloud OCR’. Also make sure you have enough units (each recognition equals one unit).

  • The app seems to be using up a lot of energy. How can I avoid that?
    You can go to Prizmo Go’s settings and activate the "Low Power Mode". Live text overlay and some other features will be disabled to save battery. Text recognition accuracy is not affected. Note that activating the low power mode in iOS Settings will automatically activate the one in Prizmo Go.

  • I want to keep the pictures I take with Prizmo Go. How can I do that?
    Just activate “Save Pictures to Album” in Prizmo Go’s settings. Make sure to allow Prizmo Go access to the Photos app.
