AutoTags are a unique (and nifty!) feature within Qiqqa.
Once you've added sufficient documents to your Library, Qiqqa will try to work out the key concepts in your documents. These are called AutoTags, and they appear in your AutoTags tree on the left of your Library.
As you add more documents, the results may change,to reflect the new contents.
AutoTags can alert you to concepts that are shared amongst your documents, that you weren't aware of. This can help you find patterns, or guide you towards important topics.
1. Ensure the metadata in your document is correct. The Title is particularly important.
2. Don't worry if the AutoTags aren't right to begin with - it will learn over time.
