The only other tool like this I have used is Q, and I gotta say that Atlas is FAR superior for content analysis. Atlas makes it easy to highlight and code text, while staying organized (e.g.: parent vs sub codes, and easy editing, easy to see coded quotes, etc.).

The support team always answer the questions and help me to use it. They have a lot of resources on their website.

ATLAS.ti is one of the best powerful qualitative data analysis software which enables researchers to discover meaningful insights by providing them with intuitive research tools and best-in-class technology. One package that contains all tools and features. Web-based real-time collaboration. No matter your license, you can use Mac, Windows, and the Web to work on projects.
