Undermind

AI co-researcher that runs deep literature searches over 200M+ scientific papers and cites every source.

Undermind is an AI literature research agent that plans and runs multi-stage searches across a database of over 200 million scientific articles, reads full texts and figures, and writes cited reports. It runs in a web app and connects to other agents over MCP.

Best for
Individual researchers, R&D teams and institutional scientists doing exploratory literature discovery or a novelty check who want citation-trail-following search beyond keyword matching.
Not for
Buyers who need a documented, reproducible search strategy for a formal systematic review or regulatory submission (see Elicit's Systematic Review workflow), point-of-care speed, or programmatic/API access. Undermind offers none of the three.

How much it does unattendedYes

Runs autonomously

The deep search plans its own query sequence, follows citations and authors and decides itself when to stop, with no human step between submission and result.

Multi-agent

Undermind is the research layer another agent orchestrates over MCP; it does not advertise several Undermind agents coordinating on one task.

Agent permissions

Scope is agreed up front through follow-up questions rather than by approving individual actions; no per-action permission model is published.

Undermind asks follow-up questions to understand exactly what you need.

GPT

Named as the reasoning engine only in the January 2024 whitepaper, which the homepage itself labels the v1 engine; no current page names any model provider.

It uses a language model (GPT-4) as a reasoning engine at key steps in a structured exploration process.

Model choice

The vendor assigns models by plan rather than letting the buyer choose: Free gets strong models, Pro gets the latest ones, and no model picker is documented anywhere.

Where you use itYes

In your editor

Documented MCP setup covers Cursor, VS Code and GitHub Copilot in VS Code, so the research tools run inside the editor you already use.

This adds Undermind to VS Code as an MCP server.

On the command line

There is no Undermind CLI of its own; terminal use comes through agent CLIs such as Codex and Claude Code, which you configure with the MCP endpoint.

Opt out of training

A no-training guarantee is stated for enterprise R&D data, covering model providers too, but the vendor makes no equivalent statement for Free, Pro or Team users.
