Gemini Deep Research: What It Does Differently

Status: Adjacent tool — context only. Not taught in the workshop, but worth knowing about because it complements Claude in specific ways.

What it is

Gemini Deep Research (Google) is a research agent that conducts multi-step web research on a topic and produces a comprehensive written report. You give it a research question or topic; it plans a research strategy, searches the web across many queries, reads and synthesises sources, and writes a structured report with citations.

Available at gemini.google.com with a Google account. The Deep Research feature requires a paid plan (Google One AI Premium).

What makes it different from Claude

Claude is primarily a reasoning and document-processing tool: it works with what you give it, either in conversation or from your disk. Its web search capability exists but is not its core strength.

Gemini Deep Research is a web research agent: its core function is finding and synthesising publicly available information at scale. It runs dozens of searches, reads many sources, and produces a report that would take a human researcher hours to assemble.

	Claude	Gemini Deep Research
Core strength	Reasoning, document processing, writing	Web research, source synthesis
Sources	What you provide + limited web search	The open web, systematically searched
Output	Whatever you ask for	Structured research report with citations
Works with your files	Yes — central capability	No
Reasoning depth	High	Moderate — breadth over depth
Citation reliability	Hallucination risk	Grounded in actual URLs (verify still)
Best for	Working with your corpus	Finding what you do not yet have

When to use Gemini Deep Research

Literature discovery: You are starting a new topic and want a rapid survey of what exists. Deep Research will find papers, books, reports, and discussions you did not know about.

Research question for Deep Research:
"What is the current state of social network analysis applied to medieval
religious movements? What are the main methodological approaches,
key scholars, and recent publications?"

The output is a structured report you can read to orient yourself — then follow up in your actual library or Zotero.

Institutional or policy context: When you need background on a funding body, a research programme, an institution, or a policy context. Deep Research finds and synthesises this well.

Preliminary landscape scan: Before writing a grant proposal section on the state of the field, a 10-minute Deep Research run can produce a draft overview that you then verify and refine.

When Claude is better

You have the sources and want to work with them (your Zotero library, your PDFs, your corpus)
You need persistent project memory across sessions
You want systematic extraction or structured output from documents
You are editing, writing, or refining text
You need something that knows your project

The practical workflow: Use Gemini Deep Research to find what to read → add findings to Zotero → use Claude to work with what you have.

Limitations

Does not access paywalled academic content — it searches the open web
Cannot work with your personal files or Zotero library
Report quality varies; always verify citations against the actual sources
The breadth-first approach means less depth on any individual source than Claude gives when you provide the paper directly
