These 22 prompts turn DeepSeek-V3.2 into a research assistant: summarizing long documents, pulling live facts with the Search toggle, comparing options, fact-checking claims, and building analysis frameworks. Everything runs free at chat.deepseek.com, and every prompt is written out in full and ready to copy.
Two habits make DeepSeek trustworthy for research. First, turn on Search for anything current and demand cited links with publication dates — without it, DeepSeek can be confidently wrong. Second, upload the real document with the paperclip instead of summarizing it yourself; the 128K-token context holds long reports so DeepSeek can cite specific sections. Verify anything high-stakes against the primary source, since DeepSeek is not a live database or finance terminal. For the full set, start at the best DeepSeek prompts roundup, and for heavier reasoning see the reasoning and math prompts.
Summarize documents
Attach the real file with the paperclip — PDF, DOCX, TXT, or code — and DeepSeek reads the whole thing. The 128K context means you can upload a long report and ask it to cite the exact sections it drew from.
1. Executive summary of an uploaded document
I've uploaded [DOCUMENT]. Read the full document and write a one-page executive summary for a [ROLE] who has not read it. Cover: the main argument or purpose, the 5 most important points, any numbers that matter, and the conclusion or recommendation. Cite the section or page for each point. End with three questions the document leaves unanswered.Why it works: Asking for section citations forces DeepSeek to read the whole upload rather than skim, and keeps every claim traceable.
2. Key claims and evidence extractor
From the attached [DOCUMENT], extract every substantive claim the author makes. For each, give a table row: Claim | Evidence they offer | How strong the evidence is (strong / weak / none) | Section. Be honest where a claim is asserted without support. Do not add claims that are not in the document.Best for: Seeing at a glance which arguments in a report are actually backed and which are just asserted.
3. Section-by-section digest
Read the uploaded [DOCUMENT] and give me a section-by-section digest. For each major section: a two-line summary, the single most important takeaway, and any figure or statistic worth remembering. Keep the original section order and headings so I can map your digest back to the source. End with one paragraph on how the sections fit together.Why it works: Preserving the source structure lets you jump straight to the section you need in the original file.
4. Plain-English explainer of a dense report
I've attached [DOCUMENT], which is dense and technical. Explain it to a smart non-specialist. Define every piece of jargon the first time it appears, use a concrete analogy where it helps, and walk through the core argument step by step. Don't oversimplify to the point of being wrong — flag anything where the nuance actually matters. Cite the section for each explanation.Best for: Getting through a legal, academic, or financial document without misreading the technical parts.
Web research with Search
Turn on Search before you send these — that switches DeepSeek from its training data to live web pages. Always demand cited links and publication dates so the answer is current and you can verify it.
5. Cited market landscape
Turn on Search. Map the current landscape of [MARKET / INDUSTRY] as of [MONTH YEAR]. Cover: the main players and their positioning, recent funding or M&A, pricing norms, and where the market is heading. Cite every source with a link, prefer primary and recent sources, and put the publication date next to each fact. Separate what's confirmed from what's still uncertain.Why it works: "Cite every source with a link" plus a date next to each fact makes the report checkable and current rather than a plausible-sounding guess.
6. Current state of a topic with dates
Turn on Search. Give me an up-to-date briefing on [TOPIC]. I want the current facts, not background from memory. Structure it as: what's true right now, what changed most recently, and what's still contested. Cite every claim with a link and its publication date, and flag anything you couldn't confirm from a recent source.Best for: A fast, sourced status check on a topic that keeps moving.
7. Source roundup for a research question
Turn on Search. Find the most important recent sources on [RESEARCH QUESTION]: studies, reports, and credible analyses from the last [TIMEFRAME]. For each, give a two-sentence summary, the key finding, the publication date, and a link. Cite every source with a link, then close with where the evidence agrees and where it conflicts.Why it works: DeepSeek's 128K context holds many sources at once, so the closing synthesis reflects the full set instead of just the last one it read.
8. Latest developments this month
Turn on Search. What are the most significant developments in [FIELD] from the last 30 days? List up to 8, newest first. For each: what happened, why it matters, the date, and a source link. Skip anything you can't tie to a dated, credible source, and note if a story is still developing.Best for: Catching up on a fast-moving field with every item dated and linked.
Compare & evaluate
Comparisons are where structure matters most. Give DeepSeek the options and the criteria, ask for a table, and turn on Search when the comparison depends on current prices or reviews. Flip on DeepThink when you want it to weigh trade-offs carefully.
9. Compare two options with a table
Compare [OPTION A] and [OPTION B] for a [USE CASE] buyer. Build a table with these rows: price, key features, main strengths, main weaknesses, and best-fit user. Be specific, not generic. If any figures could be out of date, turn on Search, pull the current numbers, and cite them with links. End with a one-line recommendation for someone who cares most about [PRIORITY].Why it works: A fixed set of table rows stops DeepSeek from cherry-picking flattering dimensions and forces a like-for-like comparison.
10. Weighted decision matrix
Turn on DeepThink. Help me decide between these options: [LIST OPTIONS]. My criteria and how much each matters (1-5): [CRITERION: WEIGHT, ...]. Score each option on each criterion 1-10, multiply by the weight, and total it in a table. Show the math, name the winner, and add one sentence on what would change the result. Be honest about any scores you're unsure of.Best for: Turning a fuzzy decision into a transparent, weighted score you can defend.
11. Pros, cons, and best-fit buyer
Give me an honest pros-and-cons breakdown of [PRODUCT / APPROACH] for [CONTEXT]. Turn on Search and pull from current reviews, forums, and documentation; cite each point with a link and date. Group into: clear strengths, real drawbacks, and "depends on your situation". End with the exact type of buyer this is right for and the type who should skip it.Why it works: The "depends on your situation" bucket keeps DeepSeek from flattening a nuanced trade-off into a false yes-or-no.
12. Vendor or tool shortlist
Turn on Search. I need a [TYPE OF TOOL / VENDOR] for [USE CASE], budget around [BUDGET]. Find current options and build a shortlist of 5. For each: what it does best, pricing, one notable limitation, and a source link with a date. Rank them for my use case and explain the ranking in one line each. Flag any option where the pricing looked out of date.Best for: A sourced shortlist grounded in current pricing instead of last year's marketing pages.
Fact-check & verify
DeepSeek can be confidently wrong from memory, so verification always means turning on Search. Demand the original source, cited links, and dates, and ask it to separate what's confirmed from what's uncertain.
13. Fact-check a specific claim
Turn on Search. Fact-check this claim: "[CLAIM]". Find the original source, what the primary evidence actually says, and how credible outlets have covered it. Rate it True / Misleading / False / Unproven with a short reason. Cite every source with a link and its date, and separate what's confirmed from what's still uncertain. If you can't verify it, say so plainly.Why it works: Search plus "find the original source" pushes DeepSeek past a memory-based guess to the primary evidence, which is where fact-checks are won.
14. Verify statistics in a document
I've uploaded [DOCUMENT]. Pull out every statistic, figure, and quantitative claim in it. Then turn on Search and check each one against a primary or credible source. In a table: Stat as stated | What the source actually says | Match / Off / Can't verify | Source link and date. Don't guess — mark anything you can't confirm as "Can't verify".Best for: Catching stale or misquoted numbers before you cite a report in your own work.
15. Confirmed vs uncertain sort
Turn on Search. Here's a set of statements I've gathered about [TOPIC]: [PASTE STATEMENTS]. For each, tell me whether it's confirmed by a recent credible source, partly true with caveats, or unsupported. Give a link and date for every "confirmed". Put the results in two clear lists — Confirmed and Needs verification — so I know what I can rely on.Why it works: Forcing statements into a "Confirmed" or "Needs verification" list is the discipline that keeps a research note honest.
Frameworks & analysis
Frameworks are where DeepThink earns its keep — turn it on so DeepSeek reasons across the inputs instead of pattern-matching a template. Feed it real context, and upload the source document when there is one.
16. SWOT from real inputs
Turn on DeepThink. Build a SWOT analysis for [BUSINESS / PROJECT] based on this context: [PASTE CONTEXT or note the uploaded file]. Keep every point specific and grounded in what I gave you — no generic filler. Output a four-quadrant table, then name the single most important item in each quadrant and the one move I should make first.Why it works: Tying every quadrant to your real context stops the SWOT from becoming the same four bullet points DeepSeek would write for anyone.
17. Root-cause analysis
Turn on DeepThink. Here's a problem I'm trying to understand: [DESCRIBE PROBLEM] with this context and data: [PASTE / UPLOAD]. Run a root-cause analysis: list the plausible causes, use "5 whys" on the two most likely, and separate root causes from symptoms. Rank causes by how well the evidence supports them, and flag what data you'd need to confirm the top one.Best for: Getting past the obvious symptom to the underlying cause, with the reasoning shown.
18. Stakeholder and risk map
Turn on DeepThink. For this initiative — [DESCRIBE INITIATIVE] — map the stakeholders and risks. Stakeholders as a table: who, what they want, their influence (high/med/low), and how to keep them onside. Then list the top 6 risks with likelihood, impact, and one mitigation each. End with the two risks I should watch most closely and why.Why it works: Separating influence from interest, and likelihood from impact, gives you a map you can act on instead of a vague list of worries.
19. Steelman and counter-argument
Turn on DeepThink. I hold this position: [YOUR POSITION]. First steelman it — make the strongest honest case for it. Then build the strongest counter-argument against it, using the best evidence you can find (turn on Search and cite links with dates if current facts help). Finish with where the disagreement really turns and what evidence would settle it.Best for: Stress-testing your own view before you commit to it in a memo or a meeting.
Synthesis & reporting
Once the research is in, the last step is pulling it together. The 128K context lets DeepSeek hold every source at once, so ask it to synthesize across the whole set and write the finished output. See the DeepSeek writing prompts for more on shaping the final draft.
20. Multi-source synthesis brief
I've uploaded / pasted several sources on [TOPIC]: [LIST or attach]. Synthesize them into one brief. Structure: where the sources agree, where they disagree and why, and what the overall picture is. Attribute each point to its source, note any source that stands alone, and flag gaps the sources don't cover. Keep it to one page and cite the source for every claim.Why it works: Explicitly asking where sources disagree — and why — surfaces the tension that a naive summary would paper over.
21. Research memo with recommendation
Using the research in this chat, write a one-page decision memo for [AUDIENCE]. Structure: the question, the key findings (with sources), the options, a clear recommendation, and the main risk to that recommendation. Be direct — lead with the recommendation, then justify it. Cite each finding, and mark any claim that still needs verification before we act.Best for: Turning a pile of research into a memo a decision-maker can act on in two minutes.
22. Literature review draft
Draft a literature review on [RESEARCH QUESTION] from the sources I've uploaded / listed: [SOURCES]. Group the sources by theme or school of thought, summarize what each contributes, and trace how the thinking has evolved. Note methodological disagreements and open questions. Cite every source, keep the tone academic but readable, and end with where the field needs more work.Why it works: Grouping by theme rather than listing source-by-source is what turns a set of summaries into an actual review.

Frequently Asked Questions
Which DeepSeek model are these research prompts built for?
They target DeepSeek-V3.2, the flagship released in December 2025, with a 128K-token context window that holds long documents in a single chat. Everything runs free at chat.deepseek.com, and the same prompts work on earlier V3 versions since Search, file upload, and DeepThink are shared features.
How do I make DeepSeek search the web?
Turn on the Search toggle before you send the prompt. It switches DeepSeek from answering from its training data to pulling live web pages. Add "cite every source with a link and its publication date" so the answer is current and checkable rather than a confident guess.
Does DeepSeek cite its sources?
With Search on and an explicit instruction, yes. Ask it to cite every claim with a link and a date, and to separate what is confirmed from what is uncertain. Without Search, DeepSeek can be confidently wrong, so demand links whenever the facts need to be current.
Can DeepSeek read my PDF, and how long can it be?
Yes. Use the paperclip to attach a PDF, DOCX, TXT, or code file and DeepSeek reads the full document, not just a summary. The 128K context window is large enough to hold long reports, so you can ask it to cite specific sections rather than pasting a shortened version.
Is DeepSeek reliable for research?
It is reliable when you turn on Search, demand cited links and dates, and paste or upload the real source instead of summarizing it. DeepSeek is not a live financial terminal or database, so verify anything high-stakes against the primary source before you act on it.
When should I turn on DeepThink for analysis?
Turn on DeepThink when the task means synthesizing many facts, weighing trade-offs, or reasoning across a long document. It spends extra compute on the reasoning, which pays off on comparisons, frameworks, and multi-source synthesis. Pair it with Search when the analysis also needs current facts.
How do the [BRACKET] placeholders work?
Anything in square brackets is a swap-in. Replace [TOPIC], [DOCUMENT], or [TIMEFRAME] with your own details before sending. The rest of each prompt is written to be copy-paste ready.
