Gemini Deep Research is a multi-step research mode that drafts a plan, browses dozens of websites on your behalf, and writes a long-form report with inline citations linking back to every source. Enable it from the compose toolbar tools menu, type your research question, approve the plan card, and Gemini works in the background for 5 to 15 minutes. The finished report can be reshaped into a Web page, Infographic, Quiz, Flashcards, or Audio Overview. Verified May 2026.

How to Use Gemini Deep Research: AI-Powered Research Assistant (2026)

Gemini Deep Research turns Gemini from a quick-answer chatbot into something closer to a junior analyst. Instead of a one-shot reply from parametric memory plus a thin web grounding pass, Deep Research drafts a research plan, browses 30 to 60 live sources, and produces a structured report with citation superscripts on every claim. This guide walks every Deep Research control with current screenshots from May 2026, covers the free-plan availability, and shows where AI Toolbox (formerly Gemini Toolbox) complements Deep Research with full-text search across every Gemini conversation (including every Deep Research report you produce) plus multi-format export. AI Toolbox is part of the same unified Chrome install that powers our ChatGPT and Claude modules.

What Is Gemini Deep Research?

Deep Research is a Gemini mode where the model drafts a plan, browses dozens of websites, and writes a structured report with inline citations linking back to every source. Where a normal Gemini chat returns an answer in seconds from the model's own knowledge plus a quick grounding pass, Deep Research takes minutes and produces a report that reads more like a briefing document than a chat reply. The deliverable is a long-form document with H1/H2 headings, body text, and citation superscripts (¹ ² ³) on every claim, plus a Sources used section listing every URL Gemini browsed with the citation count next to each entry.

Deep Research suits topics where accuracy and sourcing matter more than speed: market research, technical investigations, competitive analysis, due diligence, literature reviews. For quick lookups or conversational back-and-forth, regular Gemini is faster.

Step 1: Enable Deep Research From the Compose Toolbar

Click the + button next to the Gemini compose input to open the tools menu, then select Deep Research. The tools menu lists Upload files, Add from Drive, More uploads, then a separator and the active-mode toggles: Create image, Canvas, Deep Research, Create music (New), Guided Learning, and More tools. After you click Deep Research a checkmark appears next to the row, the menu closes, and a Deep Research chip shows up in your compose row next to the + button. That chip is the confirmation that the next message you send will run in Deep Research mode instead of normal chat.

Deep Research is one of several active modes you can toggle. Switching to Deep Research auto-disables incompatible modes (for example, a one-shot image generation request makes no sense as a multi-step research plan). To exit Deep Research, open the same menu and uncheck Deep Research, or click the X on the chip in the compose row.

Step 2: Write a Deep Research Prompt

Type a specific, well-scoped research question into the compose input. Deep Research rewards specificity in three dimensions: the entities you care about (which products, companies, libraries, regions), the time frame (current state, last 12 months, since some event), and any constraints (focus on enterprise pricing, exclude marketing-only sources, prefer technical docs). The more concrete the prompt, the tighter Gemini's research plan.

The compose row in Deep Research mode shows the Deep Research chip on the left, the active model on the right (Flash by default), the microphone, and a circular blue submit arrow. Below the compose row, two suggested action chips, Sources and Files, let you constrain the research to sources you provide or files you upload — useful when the topic is internal or you want Gemini to prioritise a known evidence set. Submit when the prompt reads the way you would brief a colleague.

Step 3: Approve the Research Plan

After you submit, Gemini drafts a research plan and shows it as a card with Edit plan and Start research buttons. The card lists the plan's stages (typically Research Websites with sub-questions, then Analyze Results, then Create Report) and an estimated time ("Ready in a few mins"). The sub-questions under Research Websites are where most of the research effort lives. Read them. If a sub-question is too narrow, too broad, or misses something, click Edit plan and Gemini lets you refine the scope, add or remove sub-questions, and rewrite the framing before any browsing happens.

Approving a plan that does not match your intent is the single biggest waste of time with Deep Research. Spend 30 seconds on the plan card before you spend 10 minutes on the report. When the plan looks right, click Start research (the blue button on the right of the card). Gemini begins browsing immediately.

Search across every Gemini Deep Research report in one query. Reports pile up fast, and Gemini's native sidebar search is limited to titles and recent chats. AI Toolbox (formerly Gemini Toolbox) adds full-text search across every synced Gemini conversation (including every Deep Research report and every plan you approved) with date, role, and exact-match filters, plus a Cmd+Shift+F (Ctrl+Shift+F on Windows) keyboard shortcut. Export any conversation as TXT, Markdown, JSON, or PDF for local archival. Free plan: 5 results per query. Premium: unlimited at $9.99 per month or $99 lifetime. Working across ChatGPT, Gemini, and Claude? All Access Lifetime ($149) covers all three modules and saves $148 versus three single-platform Lifetimes ($99 × 3 = $297). See the Gemini module →

Step 4: Watch Gemini Browse the Sources

While Gemini researches, the side panel shows "Researching N websites…" with the live list of source URLs as they are visited. A typical Deep Research run browses 30 to 60 websites. The list is real-time: each row shows the favicon, the site name, the page title or topic, and a status. You can scroll through the list to see what Gemini is consulting and to spot any low-quality or off-topic sources before the report is written (you cannot reject sources mid-run, but knowing what fed the report helps you weight the conclusions).

Deep Research runs in the background. You can leave the tab, switch to other Gemini chats, or close the window entirely. When the report is ready, Gemini surfaces an in-app notification and the chat shows the completed report. The chat history keeps a permanent record of the plan, the research progress, and the final report, so you can revisit a previous Deep Research run weeks later and re-read the sources Gemini used.

Step 5: Read the Cited Report

The finished report is a long-form document with H1/H2 headings, body paragraphs, and citation superscripts (¹ ² ³) attached to every claim. Click any superscript to open a small source preview card (favicon, site name, page title), and click the card to open the original source in a new tab. Below each paragraph or section, Gemini also surfaces a row of "source pill" cards highlighting the most-cited references for that passage, so you can verify the strongest evidence at a glance without hunting through the citation list.

Use the citations actively. Long-form AI output is only as trustworthy as the sources it cites, and Deep Research is intentionally optimised to make verification cheap. Treat any claim without a citation, or any citation that points to a source you do not trust, as a flag to dig deeper. The Sources used section at the bottom of the report lists every URL Gemini browsed plus the citation count for each, so you can spot which sources carried the most weight in the conclusion.

Step 6: Reshape the Report (Web Page, Infographic, Quiz, Flashcards, Audio Overview)

The Create button in the report header opens a menu that turns the report into a different deliverable. Options: Web page (a styled HTML version you can publish), Infographic (a visual summary with charts and pull quotes), Quiz (multiple-choice questions derived from the report), Flashcards (front/back study cards), and Audio Overview (a narrated audio summary). A "Describe your own app" input at the bottom of the menu lets you specify a custom output format that the standard options do not cover.

Reshape is where Deep Research stops being a single report and becomes a content engine. The same research run can become an internal briefing doc (Web page), a sales-team handout (Infographic), a learning aid (Quiz + Flashcards), and a commute-friendly summary (Audio Overview), all without re-running the research. Pair this with multi-format export via AI Toolbox when you need a clean TXT, Markdown, JSON, or PDF copy of the original report for downstream tooling or archival.

Plan Availability and Monthly Quotas

Gemini Deep Research is available on free Gemini accounts with a limited monthly quota, and uncapped or higher-quota on Google AI Pro and AI Ultra. Free is the right entry point: you can run a handful of full Deep Research reports per month and judge the quality before committing to a paid plan. If you find yourself bumping into the monthly limit, AI Pro increases the quota and adds access to advanced reasoning models that produce longer, better-structured reports. AI Ultra is for power users running many reports per week.

Note that Deep Research uses Gemini's web access, so accounts with web access disabled (some Workspace setups, some enterprise deployments) may not see the Deep Research option in the compose tools menu. If Deep Research is missing from your tools menu and you are on a personal Google account, check Settings to confirm web access is enabled.

Get More From Gemini with AI Toolbox

Deep Research produces reports. What it does not do is help you search across every Deep Research report you have ever produced, export reports to TXT/Markdown/JSON/PDF for archival, or share a single search shortcut that works across all your Gemini conversations. That is what AI Toolbox (formerly Gemini Toolbox) adds on top of native Gemini.

• Full-text search across every synced Gemini message, including the plan, the progress log, and the final report from every Deep Research run. Use Cmd+Shift+F (Ctrl+Shift+F on Windows) to search by message content, role, or date range with exact-match toggle. Free: 5 results per query. Premium: unlimited.
• Multi-format export of any Gemini conversation as TXT, Markdown, JSON, or PDF, useful for archiving Deep Research reports to your own knowledge base or feeding them into downstream tooling.
• Background sync to IndexedDB so searches stay fast even with thousands of conversations in your account.
• Recent searches so you can re-run the same query across freshly synced reports without retyping it.

AI Toolbox is also available for ChatGPT and Claude as part of the same unified install. The ChatGPT module adds folders, prompt library, bulk delete/archive, and media gallery. The Claude module adds full-text search with exact-match toggle and message-level bookmarks. Pricing details are on the AI Toolbox pricing page.

Frequently Asked Questions

What is Gemini Deep Research?

Gemini Deep Research is a multi-step research mode where Gemini drafts a research plan, browses dozens of websites on your behalf, and writes a long-form report with inline citations linking back to every source it used. Enable it from the compose toolbar, write your question, approve the plan, and Gemini does the rest in a few minutes.

How do I enable Deep Research in Gemini?

Click the + button next to the compose input to open the tools menu, then select Deep Research. The Deep Research chip appears next to the + button in your compose row, confirming the mode is active. Write your question and submit. Gemini will switch from a direct answer to drafting a research plan you can approve or edit.

Is Gemini Deep Research free?

Yes. Gemini Deep Research is available on free Gemini accounts with a limited number of monthly reports. Google AI Pro and AI Ultra plans increase the monthly quota and access to advanced reasoning models. Free users can still produce full research reports, just fewer of them per month.

How long does a Deep Research report take?

Most reports finish in 5 to 15 minutes depending on the topic and how many sources Gemini browses. The plan card shows an estimated time before you click Start research. You can leave the tab and Gemini keeps working in the background. When the report is ready, it appears in the chat with a notification.

Can I edit the Deep Research plan before Gemini starts?

Yes. After you submit your prompt, Gemini drafts a research plan with steps like Research Websites, Analyze Results, and Create Report. The plan card has Edit plan and Start research buttons. Click Edit plan to refine the scope, add or remove sub-questions, then click Start research when you are happy with it.

Does Deep Research cite its sources?

Yes. Every claim in a Deep Research report has inline citation superscripts that link to the source URLs Gemini used. The report also lists every source it browsed in a Sources used section, with the citation count next to each entry. Click any citation to verify the original source before relying on the claim.

Can I turn a Deep Research report into something else?

Yes. The Create button in the report header lets you reshape the report into a Web page, Infographic, Quiz, Flashcards, or Audio Overview. Each option packages the report content into a different format for sharing, studying, or publishing. There is also a Describe your own app option for custom outputs.

How is Gemini Deep Research different from a normal Gemini chat?

A normal Gemini chat returns an answer in seconds from the model's parametric knowledge plus a quick web grounding pass. Deep Research takes minutes, browses dozens of live sources, drafts a plan you can approve, and produces a long structured report with inline citations. Use Deep Research when accuracy and sourcing matter; use a normal chat when speed matters.

Conclusion

Deep Research is the right Gemini mode whenever you would have opened 30 browser tabs to write a briefing yourself. Toggle it from the + menu in compose, write a specific prompt, read the plan and approve it (don't skip this step), let Gemini browse, then read the cited report and reshape it into the deliverable you actually need. Free Gemini accounts get a monthly quota; AI Pro and AI Ultra raise it. To search across every Deep Research report you produce and export them to TXT/Markdown/JSON/PDF, install AI Toolbox for Chrome: free plan covers full-text search with up to 5 results per query. Premium ($9.99 per month) or Premium Lifetime ($99 one-time) unlocks unlimited results plus multi-format export.
