Storm

Free Stanford research prototype that turns a topic into a cited, Wikipedia-style report through simulated expert–learner AI dialogue.

51/100MonitorFreeFree

If you need a cited first draft on an unfamiliar topic and you accept that the output is a research prototype, Storm is worth an afternoon. The simulated expert–learner dialogue gives you multiple perspectives you would otherwise assemble by hand, and Co-STORM lets you steer the curation instead of accepting a finished article. Weigh it against Perplexity for fast cited answers or Elicit for structured literature extraction — Storm's edge is the long-form, Wikipedia-shaped scaffold. The terms are explicit that it is a preview with limited safeguards and that your inputs may be reused for research, so neither the citations nor the confidentiality should be treated as final.

Skip it if

Skip Storm if you need verified, publication-ready findings or current-events coverage — it is a research preview that generates drafts which can be wrong and that reflects web content only as of generation time.

The 30-second take
Biggest gripe

Your inputs — topic, stated purpose, follow-up interactions and feedback — may be collected, used for research, and distributed under a Creative Commons Attribution or similar license, which is a cost in confidentiality

Price reality

Storm is a free research prototype from Stanford's OVAL lab, so the comparison is not price but positioning: Perplexity gives you fast cited answers in a chat loop, Elicit extracts structured findings from papers, and Storm gives you a long-form, Wikipedia-shaped draft you react to and edit.

In short

Storm — Free Stanford research prototype that turns a topic into a cited, Wikipedia-style report through simulated expert–learner AI dialogue. Best for Researchers mapping an unfamiliar subfield, Students assembling a referenced overview, Writers and content teams needing a research scaffold. Free to use.

About Storm

FreeIntermediateNo APIWeb

Storm is a free research prototype from Stanford University's OVAL lab that automates knowledge curation. You enter a topic, optionally supply an outline or upload source documents, and the system runs a simulated conversation between AI agents — one playing a domain expert, the other a curious learner — to explore the subject from multiple angles before writing it up as a structured, Wikipedia-like article with inline citations drawn from real web content. Reports export as Markdown or PDF. Two modes exist. Original STORM produces a one-shot report. Co-STORM, featured on the current homepage and maintained by Dekun Ma and the Stanford OVAL team, supports interactive knowledge curation where you shape the research as it develops rather than waiting for a finished draft. The project runs in a web browser and thanks Microsoft Azure for cloud credits; sign-in is optional via a Stanford account. It suits researchers, students, and writers who need a cited first draft on an unfamiliar field. The homepage and terms state plainly that Storm is a research preview with limited safety measures, may generate offensive content, and can make mistakes — and that inputs may be collected for research and distributed under a CC-BY or similar license, so don't paste personally identifiable information. It is aimed at long-form synthesis rather than quick question-and-answer chat or breaking-news coverage.

Behind the Verdict

Storm's mechanics are the reason to use it. Rather than answering a question, it stages a conversation: one agent probes a topic as an expert, a second interrogates it as a learner, and the exchange surfaces angles a single prompt tends to miss. That transcript becomes the skeleton of a Wikipedia-style article with inline citations, exportable to Markdown or PDF. If you have ever spent two hours assembling a backgrounder from twelve open tabs, that loop is the value. Co-STORM is the newer half of the product. Where original STORM is one-shot, Co-STORM is described on the homepage as interactive knowledge curation — you participate while the research is being shaped. For an analyst mapping a new market or a grad student framing a literature review, that back-and-forth is often more useful than a finished document you have to reverse-engineer. Where it fits: broad, well-documented fields where the open web already holds plenty of material. Where it doesn't: narrow specialisms, primary experimental data, and anything time-sensitive — reports reflect web content at generation time, not the last hour. The honest caveats are the vendor's own. The terms of service call Storm a research preview with limited safety measures that may generate offensive content, warn that generated reports can make mistakes, and state that inputs — your topic, stated purpose, follow-up interactions, and feedback — may be collected, used for research, and distributed under a Creative Commons Attribution license. Do not type anything personally identifiable or confidential into it. Output that reads fluently is not output that is verified; check important claims against the cited sources.

Real-world workflow fit

Concrete scenarios for the personas Storm actually fits — and what changes day-one when you adopt it.

Graduate student framing a thesis literature review

You enter your topic, optionally paste the chapter outline your advisor gave you, and let original STORM run the expert–learner dialogue; you then export the cited draft as Markdown into your reference manager.

Outcome: You start editing a structured, referenced overview instead of staring at an empty page, then verify each citation before it goes into the draft.

Analyst prepping a client background brief

You switch to Co-STORM so you can steer the curation as it develops, correcting the angle mid-research rather than regenerating from scratch, and export the result as PDF.

Outcome: The brief reflects the angles you care about, and you spend the remaining time checking the flagged claims against their sources.

Content writer producing a technical explainer

You upload a source document to ground the research, supply an outline, and generate a cited article scaffold to draft against.

Outcome: You get a referenced structure with source previews to work from, cutting the tab-collecting phase of the piece.

Limitations

  • Storm is, in its own terms of service, a research preview from the Stanford OVAL lab with limited safety measures that may generate offensive content.
  • Generated reports can make mistakes, and you should always check important information yourself.
  • Output quality tracks the breadth of available web sources, so broad documented fields work better than narrow or fast-moving ones, and reports reflect content at generation time rather than current events.
  • Inputs — topic, stated purpose, follow-up interactions, and feedback — may be collected, used for research, and distributed under a Creative Commons Attribution license, so do not include personally identifiable information.

Ideal for

Students, researchers, and writers who need a cited first draft on a broad topic and accept using a Stanford research preview.

What this tier adds

Free entry point with no paid tier shown: Wikipedia-style reports with inline citations, both STORM and Co-STORM modes, custom topics and outlines, source-document upload, and Markdown or PDF export.

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • Your inputs — topic, stated purpose, follow-up interactions and feedback — may be collected, used for research, and distributed under a Creative Commons Attribution or similar license, which is a cost in confidentiality
  • Reports are generated from web sources at generation time and can contain errors, so budget time for manual verification of every important claim.
  • Because Storm is a research preview with limited safety measures, offensive or incorrect content can appear in output, which creates review overhead before anything is shared.
  • Very long reports take longer to generate, so the time cost scales with the length you request.

Where the pricing makes sense

The company stage and team size where Storm's pricing actually pencils out — and where peers do it cheaper.

Storm is a free research prototype from Stanford's OVAL lab, so the comparison is not price but positioning: Perplexity gives you fast cited answers in a chat loop, Elicit extracts structured findings from papers, and Storm gives you a long-form, Wikipedia-shaped draft you react to and edit.

Setup time & first value

How long it actually takes to get something useful out of Storm — broken out by persona, not the marketing-page minute.

No install: open the site, accept the terms, and start a topic — first value in a few minutes for a short report. Co-STORM and longer reports take longer because you are steering the curation or waiting on a bigger generation. Sign-in via a Stanford account is optional, not required to begin.

Migrating in
  • →From manual tab-and-notes research: paste your topic and outline into Storm to get a cited first draft you then verify and edit.
  • →From Perplexity or a chat assistant: move long-form synthesis work to Storm when you want a Wikipedia-shaped article rather than an answer thread.
Migrating out
  • ↗To a reference manager: export the finished report as Markdown and import the citations into your library.
  • ↗To Elicit or a systematic-review tool: when you need structured extraction from a defined paper set rather than a broad narrative draft.
