> I'm a high school student with a passion for tackling misinformation online. Inspired by the need for more reliable content verification tools, I decided to create Factful. It's an AI-powered web app

I stopped reading here because LLMs do not deal in facts. LLMs are statistical models of the relationships between words. An LLM can regurgitate facts that appear in its training data, but they are incapable of distinguishing between fact and fiction.

You cannot trust anything output by an LLM to be factual; it always needs to be verified. Therefore, LLMs are unsuited to fact-checking.

I'm not saying this to be a dick. I'm trying to warn you against investing a lot of time and energy into something that just doesn't work the way people want it to.
