Which AI Tools Offer Deep Research?

Last Updated: July 21, 2026

Several major AI platforms now include research-focused features. The names differ and each tool takes a slightly different approach, but the core purpose is the same: conduct multi-source research and deliver a structured report.

Deep Research is a paid feature on every major platform. Free accounts provide standard chat only. The table below reflects plan availability and pricing as of June 2025. Verify directly with each provider before purchasing, as pricing and feature availability change frequently.

Pricing and plan names shift often as providers compete on research capability. If your team is evaluating one of these tools for business use, the training opt-out column matters more than the price tag. A tool that trains on your prompts by default can turn an internal research session into a data exposure issue, particularly if client information, financial data, or proprietary strategy ends up in the conversation.

Before rolling out any AI research tool company wide, confirm the plan tier your team is actually using. Free and personal Pro accounts frequently retain data for training by default, even when a business account with the same provider does not.
