Research & intelligence

Agents that plan and run multi-step research: web and literature synthesis with citations, market and competitive intelligence, and evidence-grounded answers.

Tool	What it is	Verified
Perplexity Deep Research	Runs an extended autonomous investigation: plans and executes dozens of searches across the web and premium data sources, then returns a long structured report with citations rather than a single answer. Deep Research sits inside Perplexity's Computer agent, which takes a goal and carries the multi-step work to completion.	2026-10-22
OpenAI Deep Research (ChatGPT)	ChatGPT's autonomous research agent: it browses the web across dozens of sources, iterating and reasoning over what it finds, then compiles a comprehensive report with inline citations. Designed for questions that would take a person hours to answer from primary sources.	2026-10-22
Gemini Deep Research (Google)	Autonomously plans, executes and synthesizes a multi-step research task, analysing hundreds of sources in real time to produce cited reports — competitor deep dives to industry overviews — in minutes. It runs as an agent workflow and returns a structured report with source links.	2026-10-22
Consensus	An evidence-focused AI search engine over 200M+ peer-reviewed papers. It runs cited AI analysis of the literature and synthesises many studies into literature-review-style answers, with a Consensus Meter showing how many studies support or oppose a claim.	2026-10-22
