As answered by people managing LeetCode and Quirkos.
Quirkos's answer:
Quirkos is simple and intuitive - our design means you can prioritise getting on with your research, over learning a complex tool. This makes it a great first qualitative software package for students or academics/professionals new to CAQDAS, and much easier to incorporate into time-sensitive projects. Quirkos also prioritises its cross-platform and collaborative capabilities, with its Cloud subscription enabling you to use the software from any device and edit projects in real-time with others.
Quirkos' AI transcription add-on, Quirkos Transcribe, is highly accurate and prioritises the security of user data, making it the best option for automatically transcribing sensitive data. The transcription service is run in-house by us, all data is end-to-end encrypted and data is never shared with third parties or used for AI training. The transcription server is even solar-powered, making it eco-friendly too!
Quirkos's answer:
Since 2013, we've been led by qualitative researchers and have had the goal of creating user-friendly, affordable qualitative software for all researchers. We were dissatisfied with the user experience of other qualitative packages, and knew we could design a better experience that is quicker to learn, more enjoyable to use, and prioritises the researcher's active engagement with their data.
Quirkos's answer:
Quirkos is aimed at any qualitative researcher or research team who needs to organise and analyse long-form text data. The software excels with supporting projects that require in-depth qualitative analysis, as it is designed to keep the analyst in touch with their data. As Quirkos is so flexible in design, it's a great choice for researchers in a wide variety of disciplines (particularly across social sciences and market research) and analytical frameworks (including grounded theory, thematic analysis, and IPA). It can analyse text data from qualitative surveys, focus groups, interviews, books and articles, and can even transcribe speech from audio and video.
Due to its simplicity, Quirkos is particularly helpful for first-time qualitative researchers, or researchers who are new to qualitative software. And thanks to its student discount, Quirkos is ideal for students, whether fulfilling a tight assignment deadline or completing a thesis. If you buy our offline licence as a student, you don't have to upgrade after you graduate - it's yours forever!
