Diffyn's answer
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
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.
Diffyn's answer
Diffyn is the platform that specializes on both change management and multi-model analysis.
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.

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
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.
Diffyn's answer
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
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.
