# GPT Researcher vs Elicit

> Source: https://theagentsindex.com/compare/elicit-vs-gpt-researcher (structured, researched, re-verified)

GPT Researcher and Elicit are both in this index's "research agents" category, but they research different things for different people. GPT Researcher is open-source (Apache 2.0) and self-hosted: point it at a question, and its planner-executor-publisher pipeline fans out parallel web searches, reads and filters what it finds, and writes a long-form, cited report — typically 2,000+ words over 20+ sources. It is model- and search-agnostic, so you bring your own OpenAI, Anthropic, Google or local Ollama keys plus a search backend like Tavily, Google, Bing or DuckDuckGo. Elicit does not touch the open web at all: it is a hosted product scoped entirely to scientific and academic literature, searching over 138 million papers, and its Research Agent (launched December 2025) plans sub-questions and assembles findings into an interactive report or a structured data-extraction table pulling specific fields (sample size, method, outcome) out of each paper.

The gap widens on workflow and rigor. GPT Researcher's Deep Research mode recursively explores a topic across more branches for broader web coverage, but it has no concept of "screening" a fixed literature set — it is built to synthesize what a web search turns up, not to audit a corpus against inclusion criteria. Elicit's Systematic Review workflow does exactly that: it automates the screening step of a formal literature review, screening up to 5,000 papers on its Pro tier and 40,000 on Enterprise against criteria you set, which Elicit's own pricing page describes as "PRISMA-grade accuracy" at the top tier — a genuinely different, more auditable job than summarizing web pages. Every Elicit claim carries a sentence-level citation back to the source paper; GPT Researcher's citations point to whatever web sources its search backend surfaced, which is only as authoritative as that backend and the query.

Cost and access are the clearest fork. GPT Researcher itself is free forever — you pay only your own LLM and search API bills, typically cents to about a dollar per Deep Research run. Elicit's Basic tier is free for unlimited paper search and chat, but its Research Agent and Systematic Review usage is limited until you pay: Pro is $49/month (5,000-paper screening, 20-column extraction tables, API access), Scale is $169/month (5x usage, 30-column tables, figure extraction), and Enterprise is custom (40,000-paper screening, 40-column extraction, SSO/SAML). GPT Researcher also demands more setup: you install it, supply API keys, and run it as a Python package, FastAPI service or Docker container (an MCP server is available via a companion project, gptr-mcp). Elicit is a polished, sign-in-and-go web app with no installation at all.

## Verdict

Need a free, hackable, self-hosted agent that researches the open web and are comfortable installing a developer tool and supplying your own API keys → GPT Researcher. Need cited, structured evidence pulled specifically from published scientific literature — especially a formal systematic review with auditable screening — and want a hosted, no-setup product → Elicit. Want to research your own private documents, not just the web or published papers → GPT Researcher can point at local files directly; Elicit is scoped to its own paper index. On a zero budget and doing general research, not academic literature → GPT Researcher's free tier has no usage cap; Elicit's free Basic tier caps Research Agent and Reports usage.

## FAQ

**Is GPT Researcher or Elicit free?**

GPT Researcher is free and open-source (Apache 2.0) with no subscription — you only pay for the LLM and search API keys you supply. Elicit's Basic tier is free for unlimited paper search and chat, but its Research Agent and Systematic Review usage is capped until you upgrade to Pro ($49/mo) or above.

**Which one can search academic papers?**

Elicit — it searches over 138 million scientific papers and extracts structured, sentence-cited data from them. GPT Researcher searches the open web via whichever search backend (Tavily, Google, Bing, DuckDuckGo) you configure; it is not scoped to an academic paper index.

**Can either do a formal systematic literature review?**

Elicit can — its Systematic Review workflow automates screening against inclusion criteria you set, up to 5,000 papers on Pro and 40,000 on Enterprise, which Elicit describes as "PRISMA-grade accuracy" at the top tier. GPT Researcher has no equivalent screening workflow; it synthesizes what a web search returns rather than auditing a fixed corpus.

**Do I need to install anything?**

GPT Researcher, yes — it is a developer tool you run yourself as a Python package, FastAPI service or Docker container, with your own API keys (an MCP server is available via the companion gptr-mcp project). Elicit is a hosted web app with no installation; you sign in and use it directly.

**Can either research my own documents instead of the web or published papers?**

GPT Researcher can — point it at local PDFs, spreadsheets or docs and it researches and cites across your own files as well as the web. Elicit is scoped to its own 138M+-paper index; it does not ingest your private documents.
