Optimal has the best Tree Testing and card sorting tools. I often need to use these functions, and Optimal is the most user-friendly. While Optimal Workshop is on the higher end of pricing compared to basic survey tools, the ROI is high for dedicated UX research teams. The depth of quantitative data you get from Treejack (tree testing) and OptimalSort (card sorting), paired with automated visualizations, saves hours of manual analysis. It pays for itself quickly if you regularly validate information architecture and navigation flows for large-scale digital products.

I really like Optimal's user interface. We've demoed a lot of tools in the past year, and Optimal stands out because its interface keeps everything clear and easy to navigate, unlike other messy user research tools. I also appreciate their great customer success team; they're proactive and genuinely pleasant to work with. Moreover, Optimal's AI analysis capabilities are impressive, especially when creating highlight reels from interview videos, which is really useful for us. Finally, the price and sophisticated features like tree testing and card sorting are compelling reasons why we switched to Optimal.

I love the AI capabilities to summarise my interviews, it makes it easier to spot common themes and reduce the time I'd need take to review it all by myself, it makes my workflow easier and lighter and I finish the day less mentally tired and feeling productive to all I can achieve. As a Researcher I was looking for tools to start implementing research at my company, I like the easy of use and the flexibility of having so many features and different research methods. AI capabilities are good since it saves a lot of time, I've implemented a few tools in my day to day work life such as gemini, claude etc, I also use Miro and Figma. It works well in the sense of I get the analytics I need, then for reporting I'm creating reports on the side, and presentation on the side to present the findings from the tool. it would be good to have as part of the application ways of presenting the data, such as slide decks, or pdf reports that I can export and share with my stakeholders.
