A small sample of what our happy customers have to say about GrackleDocs

  • Springfield Technical Community College

    Grackle has been a great asset for teaching student tutors about accessibility. It is easy to demonstrate ways to develop accessible documents and make quick improvements. Everyone on our campus uses Google Workspace tools, and now everyone can check for accessibility.

    The “Export to PDF” option is also fantastic for retaining accessibility!

  • Emmanuel’s Wish Foundation

    What I love about Grackle Suite is that it makes remediation simpler at every step of our workflow. It’s easier to correct documents, easier to audit groups of files and easier to create tagged PDFs

  • Altoona Area School District

    This product has been a God-send for me as part of my duties includes Staff Development and Accessibility training.

    With our district using more and more of the G Suite products, it was important for us to find an easy-to-use accessibility solution. GrackleDocs and GrackleSheets are perfect.

    Easy to implement, easy to use and great support videos and support staff that helped lower our learning curve before using the products!

  • Barbers Hill ISD

    As our K-12 District Webmaster, I am responsible for performing accessibility compliance remediation on many non-compliant PDFs.

    I desperately needed a user-friendly solution to enable staff to help. Grackle Suite exceeded my expectations. With complex documents, it not only identified errors, but it took me directly to them and showed me how to correct them!

    I was impressed, but I wanted further proof that Grackle would be user-friendly for staff who are not compliance-savvy. I asked a co-worker to try it, and within an hour she emailed me saying, “I’m in love!” There was no turning back. We had to have Grackle!
