As answered by people managing https://open-gpt.app/ and Aretify.
Aretify's answer:
Aretify combines fact-checking with ethics auditing. Most tools only check if content is AI-generated - Aretify verifies whether AI claims are actually true by searching 15+ evidence sources, and evaluates ethical implications across 8 philosophical frameworks built by a philosophy professor.
Aretify's answer:
Aretify is the only tool that does both accuracy verification and ethics analysis in one platform. It works as a Chrome extension across ChatGPT, Claude, and Gemini - no copy-pasting needed. Free tier gives 10 verifications per day with no credit card required.
Aretify's answer:
Anyone who uses AI for important decisions - students verifying research, professionals fact-checking reports, journalists confirming sources, and anyone who wants to know if what AI told them is actually true.
Aretify's answer:
Built by a CS/Math student at UCSD who kept catching ChatGPT fabricating claims. The ethics engine was developed with his father, a philosophy professor, whose 35-page framework covering 8 philosophical traditions powers the analysis.
Aretify's answer:
Next.js, FastAPI, Chrome Extension (Manifest V3), Supabase, and integrations with 15+ evidence APIs including Semantic Scholar, PubMed, OpenAlex, Crossref, Wikipedia, and Google Fact Check.
