On document editing and tagging: Enables you to make last minute edits to the document and XBRL documents created automatically extract the updated content/values.

Auto-scoping the document: Proton can automatically identify and highlight facts that need to be tagged in a section, defining the scope of tagging.

Auto-tags XBRL tags & even suggests extensions: Proton auto-assigns XBRL tags to line items, greatly reducing time to tag. It is self-learning and remembers the tagging patterns.

One shot view of all facts: Provides a comprehensive one shot view of all the facts that will appear in the document, with filters based on unit, dates, negated values and so on.

Extensive QC Reports: Proton provides automated QC reports, for quality check of the tagging.

Unique approach to tag tuples, dimensions & create linkbases: You can tag a table, assign dimensions /tuples, and at the same time build linkbase relationships. Contexts and the relationships are auto-created by Proton.

Creation of extension taxonomy & tagging in parallel: Will enable tagging and extending at the same time. So you don't have to create taxonomy first and then tag using it.

Ability to work with multiple taxonomies including extensions: You can import prior period extended links, re-use extensions of your older taxonomy, peer taxonomy and so on.
