Taguette is a free and open source tool for qualitative research. You can import your research data, highlight and tag/code your data, and export the results, both the coded segments and your code book.
Taguette runs in your browser and can be installed on your local computer (MAC, Windows, Linux) or used as a cloud-based application.
Taguette is easy to use. Just upload your research data, highlight and add tags/codes, just as you would with highlighters and printed paper.
When you are done, you can export both your code book and the highlighted/coded data for individual codes.
