Gemini Deep Research prompts that come back with sources you can open
Scope the question, ban empty citations, and force a [VERIFY] list when the web is thin. Official Deep Research only. You still open the links.
In short: This page contains 15 copy-paste ready prompts, organized into 5 categories with a description and pro tip for each. The first 5 prompts are free instantly, no signup needed. Hand-curated and tested by the AI Academy team.
Scope
3 promptsOne question, one stop
1/15✨ What it does
Gemini scopes Deep Research to [QUESTION] and stops at [N] sources or a missing list. Read the missing list. Do not let it wander into a market map.
Run Deep Research on this only: [QUESTION]. Audience: [WHO]. Stop when you have [N] independent sources or you can name what is missing. Do not expand into a market map I did not ask for.
Pro tip: Write the stop rule. Deep Research loves to become a 20-page tour.
Include and exclude
2/15✨ What it does
Gemini researches [QUESTION] with your include and exclude lists. Drop claims that only live on excluded domains. Keep the drop list.
Deep Research on [QUESTION]. Include: [DOMAINS OR PUB TYPES]. Exclude: [EXCLUDE]. If a claim only appears on an excluded domain, drop it and say so.
Pro tip: Exclude SEO blogs if you want primary sources. Say it. The model will not guess your quality bar.
Time box the facts
3/15✨ What it does
Gemini limits sources to [FROM]-[TO] and dates anything older. Open the dated ones. Do not quote an undated claim.
Deep Research on [QUESTION]. Only use sources dated [FROM] to [TO]. If a key fact is older, put it in an Older, still cited section with the date. Do not hide the date.
Pro tip: If the question is 2026 pricing, a 2023 blog is a trap. Put the dates in the prompt.

Source rules
3 promptsOpenable citations only
4/15✨ What it does
Gemini writes only sentences with openable URLs or [VERIFY]. Click the first five links. If two are dead, rerun with stricter include.
Every factual sentence needs a URL I can open. If you cannot find a URL, write [VERIFY] and skip the sentence. No fake journals. No broken links.
Pro tip: Click. Deep Research still hallucinates tidy citations when it is tired.
Primary over commentary
5/15✨ What it does
Gemini marks each source primary or commentary and will call the brief weak if primaries are missing. Collect primaries before you brief a boss.
For [QUESTION], prefer primary sources (filings, docs, papers, statutes). Mark each source primary or commentary. If you only have commentary, say the brief is weak.
Pro tip: A stack of news posts is not research. It is a mood.
Conflict card
6/15✨ What it does
Gemini tables disagreements on [METRIC] and does not average them. You pick the source, then star the row you will use.
If sources disagree on [METRIC], do not average them. Table: source, date, number, why they might differ. Then [VERIFY] which I should use.
Pro tip: Averaging two market sizes is how decks get laughed out. Keep both rows.
Outputs
3 promptsTwo-page brief
7/15✨ What it does
Gemini returns a 2-page brief with a 5-line answer and a what-I-do-not-know list. Send the unknown list with the brief. Do not delete it.
Deep Research output: 2 pages. [QUESTION]. Sections: answer in 5 lines, evidence, conflicts, what I still do not know. Audience [WHO]. No appendix novels.
Pro tip: The unknown list is the part your reader will trust. Keep it ugly.
Slide bullets, not a speech
8/15✨ What it does
Gemini writes 8 sourced bullets for the slide deck. Paste them in, then open every URL yourself before the meeting.
Turn the research into 8 slide bullets on [QUESTION], each with a source URL. One idea per bullet. No full paragraphs.
Pro tip: If a bullet cannot hold a URL, it is a vibe. Cut it.
Method footnote
9/15✨ What it does
Gemini writes a 10-line method note for the brief. Paste it under the brief, and add the date yourself if it is missing.
Add a 10-line method note: query you ran, date, include/exclude, how many sources, what you skipped. I will paste this under the brief.
Pro tip: A brief without a method note is indistinguishable from a hallucination. Put the date.

Quality bar
3 promptsReject invented papers
10/15✨ What it does
Gemini flags unconfirmable titles and URLs in [PASTE]. Delete those rows. Find real sources yourself or rerun Deep Research.
Audit this draft for invented titles or URLs: [PASTE]. Flag any source you cannot confirm from the text I gave. Do not replace them with new invented ones. Write [VERIFY] instead.
Pro tip: Never ask it to fix a fake cite by writing a better cite. That is how you get a second fake.
Single-source warning
11/15✨ What it does
Gemini names a single-domain dependency and suggests 3 source types to add. Go find those types. Do not ask it to invent them.
If more than half of this brief depends on one domain, say so and name the domain: [PASTE]. Suggest 3 source types to add. Do not invent the new sources.
Pro tip: One blogger with 12 posts is not 12 sources.
Boss-safe summary
12/15✨ What it does
Gemini rewrites a 12-line boss summary with source or opinion on every line. Send it. Keep the long brief in the appendix.
Rewrite the brief for [BOSS] in 12 lines. Every line either has a source or is labeled opinion. Question: [QUESTION].
Pro tip: If a line is opinion, say opinion. Bosses can handle that. They cannot handle a fake URL.
When not to use it
3 promptsUse NotebookLM instead
13/15✨ What it does
Gemini picks Deep Research vs NotebookLM from [FILE LIST] and [JOB]. If the pack is enough, stay in NotebookLM. Do not re-research a pile you already trust.
I already have a source pack: [FILE LIST]. Should I use Gemini Deep Research or NotebookLM? Job: [JOB]. 5-row pick. If the pack is enough, pick NotebookLM.
Pro tip: Deep Research is for the open web. NotebookLM is for your pile. Do not pay twice.
Legal or medical stop
14/15✨ What it does
Gemini refuses to decide [QUESTION] and writes 5 background questions for a professional. Book that person. Do not treat the questions as a plan.
If [QUESTION] needs a licensed professional, refuse Deep Research as a decision and write 5 background questions I can take to [CLINICIAN OR COUNSEL]. No advice.
Pro tip: Background is fine. A care plan from Deep Research is not.
Rerun card
15/15✨ What it does
Gemini writes a rerun card with a change trigger. Rerun only if that trigger happens. Do not rerun for nerves.
Write a rerun card for this Deep Research: original question [QUESTION], date [DATE], what changed in the world that would justify a rerun, and what I should not rerun for.
Pro tip: Research has a date. Treat it like milk, not like a brand asset.
