Factful
Factful is an integrated writing environment that checks spelling, grammar, and factual accuracy while you write. It targets writers, researchers, and students who want proofreading and fact verification in one place instead of juggling separate tools.
The product uses retrieval augmented generation to search the web in real time and return citations with fact checks. It filters results toward credible news and reference sources rather than surfacing every match blindly.
Writers can trigger inline slash commands for synonyms, antonyms, translation, paraphrasing, and search without leaving the editor. A Chrome extension brings the same workflow into the browser.
Factful Analytics tracks corrections over time and highlights recurring error patterns across subjects. The changelog notes support for 100+ languages and optional model fine-tuning on paid features.
