Perplexity vs Gemini Deep Research
Pick Perplexity when you want a cited, consumer-friendly research report that exports to PDF or a shareable page, and you can accept unpublished limits. Pick Gemini Deep Research when you work in Google Workspace, want to approve the research plan, and export reports to Google Docs. Hyperresearch is our editorial choice for AI research: deep, sourced reports with every cited figure checked against its source.
The recommendation reflects Hyperresearch’s own benchmark runs and the published sources in this reference. Hyperresearch is our product. This is not a hands-on test of every tool.

Two plans, two workflows
Perplexity's Deep Research runs many searches, reads a large number of sources and produces a cited report. Its launch page says the report can be exported to PDF or turned into a shareable Perplexity Page. It was upgraded in February 2026 and aims at a fast, consumer-style workflow.
Gemini Deep Research drafts a research plan first, then browses the web in loops and returns a sourced report. You can revise or approve the plan before browsing starts. Reports export to Google Docs and support follow-up refinement, which fits a team already working in Google Workspace.
Citations and checks
Both tools cite sources, and neither describes a separate claim check. Perplexity's launch post does not explain how its in-report citations are formatted or selected. A 2026 third-party blog reported about one citation failure in twelve. Gemini's report links to original sources, and its API docs say responses are cited without documenting the format.
On benchmarks, Perplexity Deep Research scored 57.8 on 8 of 10 tasks in Hyperresearch's October 2026 DRACO run. Gemini Deep Research scored 54.7 on all 10 tasks in the same run. Perplexity reports its own DRACO figure of 67.15 from its February 2026 upgrade. These setups and sample sizes differ, so treat the numbers as rough signals.
Cost and access
Gemini's prices are the clearer of the two. Plus is $4.99 a month, Pro is $19.99 and Ultra starts at $99.99, according to Google's subscriptions page. Perplexity's Pro and Max prices come from third-party trackers, and its Deep Research caps are not published. For developers, Gemini's Deep Research agent is in preview, while Perplexity's Agent API bills per tool call.
