Write with confidence: proofreading and fact-checking in one editor
Factful verifies factual statements against live web sources, filtering the material it finds for credibility rather than simply matching wording.
Proofreading runs alongside fact-checking so you fix surface errors and substantive inaccuracies in one workflow instead of switching tools.
Monitor corrections, track how your accuracy evolves over time and spot the errors that recur across subjects.
A command system the product brands the 'Everything Key' lets you trigger writing and formatting actions without leaving the line you are editing.
