ChatGPT is the world's most-used AI assistant with 400M+ users. GPT-4o delivers native multimodal capabilities across text, images, audio, and video in a single model. o1 and o3 reasoning models tackle complex math and code. Features include Projects for persistent context, memory that improves over time, Canvas for collaborative document editing, voice mode, and Sora for text-to-video generation. The broadest feature surface of any AI assistant.

Perplexity evolved from search-with-citations into a full research platform. Deep Research runs multi-step investigations that take 2–5 minutes and produce comprehensive reports with sources — replacing hours of manual research. Perplexity Pages creates shareable, structured research documents anyone can read. Pro Search includes access to Claude, GPT-4o, and Sonar models for different task types. Shopping mode surfaces product comparisons with price tracking. The answer engine that replaced Google Search for research-heavy workflows.
Reviewer scorecard
“GPT-4o's multimodal API is production-ready and covers text, vision, audio, and code in one endpoint. o3 is now my go-to for hard algorithmic problems. The breadth of the platform — Projects, memory, custom GPTs — means there's always a right tool in this toolbox.”
“Deep Research is legitimately impressive for technical evaluation — comparing libraries, auditing security postures, understanding architecture decisions. What used to take 2 hours of reading docs and Stack Overflow now takes 5 minutes and comes with citations I can verify.”
“Too many model tiers (o1, o3, GPT-4o, GPT-4o-mini, GPT-4.5) creates confusion. But the platform keeps shipping and the quality is undeniable. Claude still edges it on reasoning depth, but for everything else, ChatGPT is the safe default.”
“Citations remain the core differentiator vs ChatGPT. Every claim is sourced and you can click through. Hallucination risk drops dramatically when the model knows it has to cite. Deep Research is good but sometimes slow — it works best when you have a few minutes, not seconds.”
“Canvas transformed my writing workflow — real-time co-editing, tone controls, and length adjustment without reprompting. Sora for quick video concepts is a creative shortcut I use weekly. Voice mode on walks is genuinely useful for ideation.”
“The memory feature compounds — the longer you use it, the more personalized it becomes. Projects make ChatGPT a persistent collaborator, not a stateless chat window. OpenAI is building the ambient AI layer and ChatGPT is the front door.”
“Perplexity Pages is the underrated bet — turning AI research into shareable documents is how knowledge workers will collaborate in the future. The roadmap (Deep Research, Pages, shopping, Pro with multiple models) is building the AI-native knowledge platform, not just a better search engine.”
