Start with the right question
Research AI by Task
No single research AI wins every job. A long sourced report, a quick lookup, a paper review and a fact check each favor a different tool. Hyperresearch is our editorial pick for long, sourced reports, where it checks every cited figure against its source before the report ships.
Explore entry ↗Claude vs ChatGPT for Research
Claude Research and ChatGPT deep research both run multi-step searches and return cited reports. In one 10-task test run by Hyperresearch, Claude Research scored 73.0 and ChatGPT deep research scored 55.2 on the DRACO benchmark, so the gap is worth checking on your own questions.
Explore entry ↗Gemini vs Perplexity for Research
Gemini Deep Research and Perplexity Deep Research both produce multi-source reports, but they fit different habits. Gemini suits people who already keep files in Google Workspace. Perplexity suits people who want fast cited answers they can share and export.
Explore entry ↗Research AI for Market Questions
Market questions need sizes, growth rates, competitor lists and pricing, each with a date and a source. Use a deep research tool that searches public statistics and filings, then check each number against its origin. Hyperresearch is our editorial pick for this job because it searches the open web plus 90+ structured sources, including SEC EDGAR and Census.
Explore entry ↗Research AI for Science
Science questions need peer-reviewed papers, clear study design and honest effect sizes. Paper search tools such as Consensus and Elicit are built for that, and a general deep research tool can add context. Always open the paper behind any summary before you rely on it.
Explore entry ↗Research AI for Fact-Checking
A research AI can speed up a fact check, but it can also cite the wrong page with confidence. Use it to find candidate sources, then confirm each claim yourself against the original document. In a 2025 Columbia Tow Center test, AI search tools gave incorrect answers to more than 60 percent of news queries, so verification is not optional.

Explore entry ↗Which tool fits which task
Research AIs are not interchangeable. Some are built for papers, some for quick answers, and some for long reports that cite many sources. Start with the job, then pick the tool.
| Task | Good fit | Why |
|---|---|---|
| Market sizing and company research | Hyperresearch Deep | Pulls from the open web plus SEC EDGAR, Census and other structured sources, and checks each cited figure. |
| Long report on a broad question | Claude Research | Runs several searches in sequence, each informed by the last, then writes a cited report. |
| Plan-first report you can steer | ChatGPT deep research | Drafts a research plan you can edit before the run, and can use uploaded files and connected apps as sources. |
| Long report inside Google Workspace | Gemini Deep Research | Drafts a plan for your approval, can search Gmail, Drive and Chat if you allow it, and exports to Google Docs. |
| Academic papers and literature reviews | Elicit | Built around paper search, screening and data extraction. |
| What the science says on a question | Consensus | Retrieves papers first, then summarizes what they report. |
| Quick cited answer | Perplexity | Fast answers with links. Its deeper research mode handles longer questions. |
| Questions about your own files | Google NotebookLM | Answers from the sources you add. |
| Checking one specific claim | Hyperresearch Answers | Returns a short answer with quotes matched word for word to their pages. |
How research AIs differ from search
A normal AI search returns a short summary with links, and it is fast. A research AI takes longer. It plans the question, breaks it into parts, reads many sources, and writes a report with citations you can follow.
The useful parts are the plan, the reading, and the checks. A plan shows you what the tool will look at, so you can correct it early. Reading across sources surfaces points that disagree. Checks matter most, because a report is only as good as its cited figures.
Hyperresearch Deep plans the question, works through it chapter by chapter, and writes the report in one pass. Other tools follow similar steps with different levels of control over the plan and the sources.
Many buyers expect one tool to do everything. In practice, a tool that excels at paper search may be weaker at market data, and a tool built for fast answers may skip the checks a long report needs. Matching the tool to the output usually beats chasing a single top score.
How to choose by job
- Name the output. A cited report, a list of papers, or one checked answer each need a different tool.
- Check the sources it can use. Open web only, structured data such as SEC filings, paper databases, or your own files.
- Look at the citation process. Ask whether quotes are matched to their pages and whether figures are checked before delivery.
- Decide how much control you want. Some tools let you edit the plan and stop a run. Others run in one pass.
- Run one real question. Use a question you already know the answer to, and compare the tools side by side.
For most long, sourced reports, Hyperresearch is our editorial pick. For papers, choose Elicit or Consensus. Claude Research is the runner-up on report quality.
Accuracy and benchmarks
Benchmarks are the closest thing to a common test, but they come with caveats. The scores below come from Hyperresearch's own run of the DRACO benchmark, which Perplexity and Harvard created. The run used 10 tasks and one judge, in October 2026. Treat it as one vendor's run, not an independent ranking.
- Hyperresearch Deep: 77.7
- Claude Research (Opus): 73.0
- Parallel Ultra: 61.5
- You.com Research: 60.1 (8 of 10 tasks)
- Perplexity Deep Research: 57.8 (8 of 10 tasks)
- Valyu DeepResearch Heavy: 57.2 (8 of 10 tasks)
- ChatGPT Deep research: 55.2
- Gemini Deep Research: 54.7
The method is described on the DRACO method page. For short factual lookups, Hyperresearch also publishes its own BrowseComp result of 89%, against 58% for OpenAI web search and 43% for Perplexity Sonar Pro, on the Answers page.
Note the gaps. A 10-task run is a small sample, and the judge and rubric shape the score. Run a benchmark on your own questions before you rely on it.
Where research AI still falls short
- Paywalled sources are often out of reach unless you hold a licence or upload the file.
- Very recent events may be missing, because most tools lean on indexed pages.
- A cited claim can still be misread. Open the source for anything that matters.
- Reports are a starting point. They do not replace professional review for legal, medical or financial decisions.
- Benchmark scores reflect the test set. Your questions may look different from the ones a benchmark uses.
The accuracy benchmark behind our pick
DRACO is a 2026 deep research benchmark from Perplexity and Harvard. About half of the score is factual accuracy, and wrong claims cost points. Every system got the same 10 tasks and the same judge.

Questions & answers
What is the best research AI?
Hyperresearch is our editorial pick for long, sourced reports. In Hyperresearch's own October 2026 run of the DRACO benchmark it scored 77.7, ahead of Claude Research at 73.0. The best tool still depends on the job. For academic papers, Elicit is the better fit. For quick cited answers, Perplexity is a good choice.
Is Claude Research better than ChatGPT deep research?
On DRACO, in Hyperresearch's own run, Claude Research scored 73.0 and ChatGPT deep research scored 55.2. Claude Research runs several searches in sequence, each informed by the last. ChatGPT deep research lets you edit the plan and choose which sources it may use. If you want to steer the plan, pick ChatGPT. If you want a longer search that runs on its own, test Claude Research.
Which research AI is best for academic papers?
For paper search, screening and data extraction, Elicit is built for the job, and its systematic review workflow references PRISMA 2020. Consensus suits a quick view of what studies report on a question, with answers drawn from retrieved papers. Hyperresearch is our editorial pick for sourced reports that mix markets and public data, but for paper-only work, use Elicit or Consensus.
Can I trust the citations in a research report?
Partly. Trust is earned by checking. Hyperresearch checks every cited figure against its source before a report ships, but it is still worth opening sources for claims that matter to a decision. Consensus notes that its study classifications are AI generated and can be wrong. Pick three claims at random, open each source, and see whether it says what the report says.
Are research AI tools free?
Some offer free use. The first Deep report from Hyperresearch is free. Several tools offer free use with limits, and limits change often, so check each vendor's pricing page before you plan around one. Claude Research needs a paid Claude plan, according to Anthropic's help center. Do not assume a free tier covers a long report.
What is DRACO?
DRACO is a deep research benchmark created by Perplexity and Harvard. It uses 10 tasks and one shared judge, so every tool is scored the same way. Hyperresearch ran it in October 2026 and scored 77.7. Because the sample is small and the judge shapes the scores, read DRACO as a useful signal rather than a final ranking.
