Reduce cost and drive sales of open-ended questions

Open-ended questions provide a lot of value from a research perspective, as they introduce less bias than multiple-choice questions. However, they are considered a major cost driver by most market researchers, as evaluation is time consuming and expensive. Caplena helps market research professionals by:

  • Reducing the effort of analysing open-ended questions, saving costs and enabling more competitive pricing;
  • Improving data handling, data consistency and data versioning by providing a central platform onto which all stakeholders have access;
  • Increasing quality awareness and enhancing quality assurance through better overview, integrated accuracy metrics and code suggestions of the AI;
  • Paving the way for decentralized evaluation of surveys by relying on freelancers.

All this while you stay in control: Caplena is no black box which just gives you a bunch of keywords, but rather learns how you code.

Understand your employees & clients better and faster

Successful companies listen to their employees as well as their clients via recurring surveys, closely monitoring the needs and thoughts of their key stakeholders. But reading every response is time-consuming if we're looking at hundreds, to downright impossible if talking about hundreds of thousands of responses. Caplena lets you automate large parts of that and spend more time on solving real problems by:

  • Categorizing responses based on previous iterations of the same survey, allowing you to get to a fully automated solution;
  • Improving data handling and history keeping for creating time series through our centralized platform;
  • Providing real-time statistics on the results.

All this while you stay in control: Caplena is no black box which just gives you a bunch of keywords, but rather learns how you code.

Bring your research projects ahead without bothering with complex software suites

Whether you are a machine learning PhD [creating NLP training sets] or a student of psychology [evaluating surveys] it is very likely that at one point of time you will have to deal with large amounts of text that demand categorization and analysis. Let Caplena help you make most of your limited time by:

  • Boosting your productivity of categorizing & annotating;
  • Getting you up to speed almost instantly: No need for installing any suites or familiarizing yourself with software beasts;
  • Offering fair pricing specifically for academia, only pay for what you really need;
  • Making sure your data is safe and sound.

All this while you stay in control: Caplena is no black box which just gives you a bunch of keywords, but rather learns how you categorize texts.


Don't take our word for it. Here's what our customers say.

At Factworks we were looking for an efficient and reliable solution for analyzing open-ended survey responses to complement our text analytics offering. We needed a flexible solution which we found in Caplena, whose intelligent algorithm has increased our efficiency with both tracking and ad hoc studies. The team is very responsive and capable of providing even highly customized solutions.


At Link we have chosen Caplena as our everyday tool for coding responses. It helped us to become significantly more efficient at evaluating open-ended questions, radically improved our data management and enabled us to execute on projects with tens of thousands of responses.

At success drivers we were in need of a powerful survey-coding platform for our new product. After evaluating a number of commercial and open-source solutions we found Caplena, which outperformed all alternatives by a mile. We now use Caplena to perform insightful and automated key driver analysis on NPS surveys for our clients and can wholly recommend it.
