As a parent navigating the challenges of supporting an adult with severe autism, I took a closer look at AI tools—ChatGPT, Claude, Perplexity Pro, and Gemini Deep Research—to see how they could help parents like us. ChatGPT and Claude gave general advice, but Claude caught my attention by sharing relatable fictional case studies. Perplexity Pro provided references, but it felt like you had to dig for the gold. Then there’s Gemini—it delivered tons of info, including research plans and real-world examples, though not always specific to severe autism. While none fully captured the unique challenges we face, Gemini stood out for its sheer amount of helpful content, making it my top pick for research, even with its quirks.
