KH Coder vs QualCoder

KH Coder is software for quantitative content analysis, text mining, and computational linguistics. It can be used with free-response survey answers, interview records, newspaper articles, and other text. The analysis options include word-frequency lists, keyword searches, KWIC, cluster analysis, multidimensional scaling, co-occurrence networks, correspondence analysis, self-organizing maps, and coding cross-tabulations. Visualizations include network views with betweenness centrality and community detection, correspondence-analysis plots, heatmaps, line charts, and bubble plots. Statistical analyses can be viewed with the source-text context, and analysis can run without an internet connection. The English site lists text support for Catalan, Simplified Chinese, Dutch, English, French, German, Italian, Japanese, Korean, Portuguese, Russian, Slovenian, and Spanish. KH Coder runs on Linux, macOS, and Windows, with on-premise deployment. Users can customize it by editing R and MySQL code. The free Windows Starting Edition limits analyzable data and some features and is an older beta; the paid Base Edition is presented as the full version. The Mac Edition costs $99.00 USD once and requires Apple silicon, macOS 11 or later, and 5 GB of available disk space.

QualCoder is free, open-source software for qualitative data analysis on Linux, macOS and Windows. It supports coding text, images, audio and video, organizing codes in hierarchies, and keeping journals and memos alongside analysis. Users can generate reports, most of which can be exported as HTML, ODT, plain text or Excel. Projects and codebooks can be exported using the REFI-QDA standard, while codebooks can be imported from plain text or CSV files. Coding data is stored in a SQLite database in the project's data folder. QualCoder is intended for one person at a time; simultaneous access to a project can corrupt its database. VLC is optional for general use but required for audio or video coding. Optional AI features support topic exploration, assisted coding, text analysis and code chats. AI is off by default, and supported providers include cloud services and local models such as Ollama. Provider API access is pay-per-use and may incur charges for each request.
