OpenAI's deep research will find, analyze & synthesize hundreds of online sources to create a comprehensive report minutes.

I’ve tested it across multiple domains, and the speed and depth of its insights are unreal—what would normally take me hours, if not days, is now condensed into minutes.

The tool doesn’t just regurgitate facts; it actually synthesizes information in a way that feels like having a top-tier research assistant. Whether it’s legal analysis, investment reports, or technical breakdowns, it compiles sources, structures findings, and presents a level of clarity that’s hard to match.

The citation system is solid, though I’ve noticed that in highly specialized fields, it can occasionally misinterpret details, meaning a final manual check is still necessary.

That said, I don’t think its limitations take away from how powerful it is. It’s especially strong at identifying patterns and connections that might otherwise go unnoticed, making it feel like a true step toward AI-assisted research rather than just an advanced search engine.

Some might argue it’s not "creating" new information, but in practice, the way it organizes and presents data often leads to insights I wouldn’t have reached on my own.

There’s no doubt that tools like this are shifting the way research is done, and while it’s not perfect, it’s the closest thing I’ve seen to an AI that genuinely enhances intellectual work rather than just speeding it up.
