Overview

Checks the accuracy of webpage content based on other web sources.

FactoidL is committed to being an open-source tool that keeps fact-checking transparent, free, and easy to use. For feedback or contributing to the project, please contact: factoidlproject@gmail.com Release Notes (Aristotle, FactoidL v2.6): * Aristotle Strategy: Tighter specification of article/unimportant words and regex of negation. Slight co-reference resolution (2-3 fragments of text apart if original factoid can't resolve itself). * Common algorithm/functionality code is now in factoidl-common.js files. * Updated visual assets to be based off of a crisper SVG logo. * Repaired broken and stalling API requests to default source (Wikipedia). Including revising service worker tasks. * Optimized topic search by weighted term set of page title + all scraped factoids, with fallbacks on first sentence and then page title. * Added verification bar that shows the amount of verified, verified false, and unverified factoids. * Various minor code fixes like upgrading dependencies and script security. Upgrade to Manifest V3 for extensions as well as fixed extension functionality between tabs.
