In building our relationship, the Continual Engine team has taken great stride to learn and understand our challenges associated with the design and scaled remediation of accessible instructional materials.
Senior DirectorA leading public university in Virginia
It has been a truly positive experience working with the Continual Engine team and their Invicta tool. I can certainly attest to the efficiency, consistency, and excellent quality of the alternative text that has been developed thus far for about 30 titles across our Math, Computer Science and Engineering discipline lists. With another 40 projects currently underway, my team and I now have the confidence to have final quality product ahead of our scheduled deadlines while improving costs throughout the production list. Developing this new workflow and implementing it to our lists to come will undoubtedly support providing an excellent learner experience for all our consumers.

My Physical Science titles have benefited substantially from using Invicta for our alt text. We have seen significantly improved costs and turnaround times over using more traditional alt text methodologies. The overall quality has been very high and has impressed subject matter experts who have reviewed the Invicta output. We were also impressed by the process by which subject matter expert feedback was applied to the Invicta tool to continuously improve results. We have very high confidence in this tool and the team!

I wanted to say a huge thank you for your amazing, speedy turnaround on the alt text for our first edition Chemistry title, I know this was a big ask from us to create such a large volume of complex alt text on a very tight timeframe, and I am super appreciative and grateful for your outstanding work. Thank you very, very much!
Managing ProducerOne of the largest education publishers and learning companies
The Continual Engine Team has been an invaluable business partner. Roughly three years ago, we began conversations about the need to generate exemplary alt text at scale. Flash forward to the more recent past and the Continual Engine Team worked in concert with us and two of our primary business partners to seamlessly weave the Invicta tool into our existing production process. The results of all their efforts have been radical improvement in quality, time to market, and efficiency.
