## Consensus

Consensus works like a scholarly search engine supercharged by AI. Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided.

The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query.

Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis.

**Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options.

- **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
- **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
- **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
- **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
- **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects.

**Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows

**Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers

## LibraLM

LibraLM is built around a simple proposition: books are static, so LibraLM brings them to life. It offers AI-ready summaries and chapter breakdowns of more than 50 nonfiction bestsellers, then exposes that knowledge through an MCP server and API so you can build interactive experiences on top of it.

The main workflow runs through an MCP (Model Context Protocol) server for Claude Desktop. You install the extension, paste in a free API key, and then ask your assistant to work with a specific book. From there you can create negotiation simulators, financial advisors, habit trackers, games, journals, and other tools that respond using frameworks drawn from the book rather than generic model guesses. A free API key includes 50 calls with secure Auth0 authentication and no credit card.

LibraLM also ships its own showcase apps, such as the iOS LibraLM Scenario app for practicing high-pressure conversations with a 30-second timer and expert frameworks from bestselling books, plus web tools like a Wealth Ladder Calculator, a Negotiation Simulator, and Date Journal Pro. The book library covers business, self-help, and productivity titles including Atomic Habits, Never Split the Difference, Outlive, The Cold Start Problem, and I Will Teach You to Be Rich, with new titles added regularly.

**Pricing & Plans:** LibraLM uses a simple freemium model. The Free tier is $0 per month and includes 50 API calls per month, access to all book summaries, MCP server integration, and community support. Pro is $9.99 per month and adds unlimited API calls, priority access to new books, advanced app templates, and priority support. You can start with a free API key—50 calls, no credit card, secure Auth0 signup—and cancel anytime.

- **50+ book summaries:** Access structured summaries and chapter breakdowns from 50+ nonfiction bestsellers directly inside your AI tools.
- **MCP server integration:** Install the LibraLM MCP server in Claude Desktop and connect with one API key to pull book knowledge into your assistant.
- **Book-to-app experiences:** Turn any covered book into games, negotiation simulators, financial advisors, and study companions that respond using real book frameworks.
- **API keys and free calls:** Grab a free API key with secure Auth0 authentication and start making up to 50 free API calls without a credit card.
- **Fast no-code building:** Build working apps in minutes using templates for advisors, habit trackers, negotiation trainers, and more.

**Strengths:** Free tier with 50 API calls and no credit card required; Purpose-built MCP integration makes it easy to use book knowledge inside Claude Desktop; Library spans popular, well-known bestsellers rather than obscure titles; Templates let you build working apps in minutes without coding

**Limitations:** Free tier is capped at 50 API calls per month, which goes quickly when testing; Requires wiring up an MCP server (Claude Desktop 1.0+ on macOS, Windows, Linux) to unlock the main workflow; The 50+ summary library focuses on business, self-help, and productivity bestsellers; No dedicated mobile builder yet beyond the iOS Scenario app
