Building With Research: A Practical System
Deep Research is a class of AI feature — pioneered by OpenAI in early 2025 and now shipped by Anthropic, Google Gemini, Perplexity and xAI — where an agent runs a multi-step research task over the open web (and sometimes your own documents) and returns a structured report with citations. Instead of a single search-and-summarise, the agent plans sub-questions, browses dozens or hundreds of pages, cross-checks sources, and often runs for 5–30 minutes. This guide pulls together everything on Onexial tagged research — 15 connected nodes across definitions, workflows, tool stacks, comparisons, prompts and applied use cases — and orders it the way you would actually learn it: vocabulary first, then process, then tooling, then execution. Every item below links to a full node with its own examples and connections, so you can go as deep as you need without losing the map.
Core concepts behind Research
Before wiring anything together, the vocabulary has to be precise. These 2 definitions cover the terms that show up in almost every Research discussion — each one links to a full entry with an example and its own connections inside the graph.
Deep Research (AI)
Long-running AI research task that produces a cited multi-page report.
Research Automation
Research automation turns a question into a sourced, structured answer using search, retrieval, extraction and synthesis agents.
Workflows: how Research runs end to end
Concepts only matter once they become a repeatable process. Below are 4 documented workflows that apply Research to a concrete problem, with the steps, the tools involved and the variations worth testing.
Personal Research Assistant Workflow
A repeatable system to research any topic deeply in under 30 minutes.
AI Market Research Report in One Afternoon
From blank page to sourced, structured 20-page market report in ~4 hours.
Turn Deep Research Into a Weekly Executive Brief
Use an AI Deep Research agent every Monday to produce a cited market brief in 20 minutes.
Build a Research Automation Pipeline
Question in, sourced structured brief out — on a schedule.
The Research tool stack
A stack is a set of tools chosen for one job, not a list of favourites. These 3 stacks show which combinations hold up in production for Research, and what each layer is actually responsible for.
AI Research & Knowledge Stack
Default toolset for analysts, founders and creators doing deep research with AI.
Solo Market Researcher Stack
One person running weekly market intel across 20+ companies.
Research Automation Stack
Search, fetch, extract and synthesise sourced briefs on a schedule.
Prompts you can reuse
Prompts are reusable components. Each of these 4 prompts is written to be dropped into a Research workflow with minimal editing, including the context it expects and an example output.
Market Research Synthesizer
Compress 10-20 sources into a 1-page decision-grade brief.
Competitor Teardown Prompt
Deep-dive one competitor from public artifacts.
Deep Research Prompt Template
Reusable Deep Research prompt that produces cited, structured reports every time.
Sourced Research Brief Prompt
Produces a structured brief where every claim carries a citation.
Real applications of Research
Finally, 2 applied use cases: the situation, the system used to solve it, and the outcome. This is the layer that turns Research from an idea into leverage.
Tech Creator Replaces a Research Assistant With a Workflow
A YouTuber cut their research time per video from 8 hours to 90 minutes.
Consultancy Automates Weekly Market Scans
A sourced competitor and market diff replaced a manual research day.
Frequently asked questions
- Which Deep Research tool is best in 2026?
- OpenAI's o3-based Deep Research and Anthropic's Claude Research are strongest on synthesis and citation quality. Perplexity is fastest and best for shallow-but-broad scans. Gemini is strongest inside the Google ecosystem.
- How long does a Deep Research run take?
- Typically 5–30 minutes depending on the tool and the scope of the question. Most vendors let you leave the tab and get an email when it is done.
- Can I run Deep Research on my own private documents?
- Some tools (Claude, Gemini, enterprise ChatGPT) can pull from connected drives or an uploaded corpus. The pattern is often combined with RAG for private-knowledge grounding.
- How is Deep Research different from just asking ChatGPT?
- A normal chat answer is one round-trip. Deep Research plans sub-questions, browses many sources, cross-checks, and produces a structured multi-section report with inline citations.
