Hi, I’m John Deris — the creator of Prompt Atlas.
I hold a Bachelor’s degree in Law and am currently pursuing a postgraduate specialization in Generative AI and Intelligent Agents for Business, complementing my hands-on testing of AI tools with formal study in generative AI, intelligent agents, data, automation, and AI strategy.
My legal education informs how I approach these tests: examining evidence, questioning assumptions, and distinguishing supported conclusions from claims that need verification.
I created this site because choosing the right AI tools has become unnecessarily confusing. Every week a new tool launches with bold claims, polished landing pages, and feature lists that look impressive on paper. But when you actually try to use them for real work — research, writing, customer service, marketing, or decision-making — the difference between marketing and reality becomes clear.
My goal with Prompt Atlas is simple:
Test AI tools the way a small business owner or independent professional would actually use them, then explain clearly what works, what doesn’t, and where the limitations are.
I don’t just list features. I run practical, side-by-side tests with the same prompts and constraints, so you can see how the tools behave in realistic situations instead of relying on marketing copy.
