ChatGPT deep research vs Microsoft Copilot
Pick ChatGPT deep research when you want a long, multi-step web report from OpenAI's research agent, with a limited allowance on the free tier. Pick Microsoft Copilot when you want a free, web-grounded assistant inside Microsoft apps for quick questions. ChatGPT's deep research is the longer report; Copilot is the cheaper everyday tool. Hyperresearch is our editorial choice for an AI research tool: sourced reports with every cited figure checked, and the first Deep report is free.
The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

Long report versus quick answer
ChatGPT's deep research is built to run a multi-step search and write a long report, which can take several minutes. It suits a question where you want a structured brief rather than a sentence or two. It is included in the main ChatGPT app across tiers, so you do not need a separate product.
Copilot is built for quick answers. It runs web search for current questions and writes a reply, and it sits inside tools many people already open. For a short factual check, that is faster.
Plans and limits
OpenAI's pricing page lists Free, Go, Plus and Pro plans. It describes deep research access as limited on Free and Go, expanded on Plus and maximum on Pro, without publishing exact counts. Because the numbers are not published, plan for them to change, and check the app before you rely on a count.
Microsoft's free Copilot costs nothing and does not state a fixed cap. Microsoft 365 Premium is listed at $19.99 a month by third-party reports. Confirm current plan details on Microsoft's own pages.
Checking the output
Both tools produce answers you must check yourself. OpenAI's reports are described as sourced, but the documentation does not describe a separate claim check. Microsoft has not said how Copilot shows its sources.
On the DRACO benchmark, a run Hyperresearch published itself in October 2026, ChatGPT Deep research scored 55.2, against 77.7 for Hyperresearch Deep. These are Hyperresearch's own results, judged with one shared judge.
Consider the workflow as well as the output. ChatGPT deep research sits in the same chat window as the rest of the product, so a report can lead straight into follow-up questions. Copilot sits in the apps people already open, which is useful for pulling a fact into an email or a document. For a team that writes briefs, the report format is the better fit. For a team that answers small questions all day, Copilot's position inside the Microsoft stack is the bigger advantage.
Both tools ask you to trust their summaries, so keep a short checklist. Open at least three sources for each key figure, confirm the date of each source, and note anything the tool could not find. That habit matters more than the choice of tool.
