## Paperguide

Paperguide has evolved from a general-purpose "chat with your PDF" study assistant into a research platform aimed squarely at rigorous evidence work. Its current centrepiece is Systematic Review: you define a protocol, run a documented search, screen abstracts and full texts with per-criterion evidence prepared by AI, resolve conflicts between two independent reviewers, and finish with verified extraction tables plus a PRISMA flow diagram generated from your own counts. The design principle is that AI prepares evidence but never casts the decisive vote — every screening call, extracted value and synthesized claim is traceable to a named source statement and a human verifier.

The rest of the product supports that workflow from the front end. AI Search answers plain-language research questions across more than 200 million peer-reviewed papers with each assertion linked to its source; the Reference Manager imports from Zotero or Mendeley, adds papers by DOI and fetches open-access PDFs automatically; Extract Data turns a stack of PDFs into a structured, cited comparison table you can export to CSV or Excel; and the Research Agent handles multi-step literature reviews up to 50 papers, organized by theme.

Paperguide also ships an AI Writer for citation-grounded drafting, an MCP integration, and a plagiarism checker, with shared team workspaces that keep papers, annotations and reviews attached to the project rather than to one person's account. It is used by academic researchers along with medical device, HEOR, pharma and government policy teams, and reports over one million researchers on the platform. Pricing runs from a free tier through Plus, Pro, Evidence Teams and custom Enterprise plans billed per seat annually.

**Pricing & Plans:** Freemium with a free plan (1,500 AI credits per month plus limited agents and reference manager) and paid per-seat tiers billed annually: Plus around $12/seat/month, Pro around $29/seat/month, Evidence Teams around $89/seat/month with dual-reviewer screening, and custom Enterprise pricing. Yearly billing advertises savings up to 41%.

- **AI Search over 200M+ papers:** Ask a research question in plain language and get a synthesized answer drawn from PubMed, arXiv, OpenAlex and Semantic Scholar, with every claim linked to its source paper.
- **Auditable Systematic Review:** Run PRISMA-style reviews with a predefined protocol, recorded screening decisions, dual independent reviewers and a conflict resolver, and a PRISMA diagram generated from your actual counts.
- **AI-native Reference Manager:** Import from Zotero or Mendeley, add papers by DOI, and get metadata and open-access PDFs fetched automatically, with annotations and notes that feed every other workflow.
- **Cited data extraction tables:** Define custom extraction columns and have AI fill them across many papers, with each value linking back to the sentence it came from, exportable to CSV or Excel.
- **Citation-grounded AI Writer:** Draft from your own library and 200M+ papers in the same document, switching between 1,000+ citation styles without manual reformatting and without invented references.

**Strengths:** Statement-level traceability: click any claim to land on the exact source sentence; Combines search, reference management, extraction and writing in one workspace; Per-criterion evidence speeds up abstract screening and improves reviewer consistency; Free tier is genuinely usable, and annual billing discounts are generous

**Limitations:** Credit-based limits can be reached quickly on heavy research-agent usage; The advanced systematic review features and dual review sit behind the pricier team tiers; It is primarily English-oriented, which may suit non-English primary research less well; Newer compliance certifications such as SOC 2 and ISO 27001 are still listed as coming soon

## Rayyan

Rayyan is a dedicated platform for systematic literature reviews and evidence synthesis, used by more than a million researchers at tens of thousands of institutions across over 190 countries. Rather than being a general reference manager, it maps directly onto the standard review pipeline: importing references from multiple sources, organizing them into a library, inviting collaborators with defined roles, deduplicating the corpus, and then working through title and abstract screening followed by full-text screening with conflict resolution.

The AI layer centers on ResearchPilot, which provides zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and automated data extraction designed to be dramatically faster than manual workflows. Rayyan also ships a Systematic Auto-Resolver that can deduplicate up to 200,000 references based on your own protocol in a single action, plus a mobile app that lets reviewers screen studies on the go or even offline. Small productivity touches like programmable hot keys and randomized data sampling help teams divide large workloads without losing coordination.

Beyond screening, Rayyan covers the back half of a review too. Teams define structured data extraction fields, apply PICO frameworks to structure evaluation, capture study-level data, assess Risk of Bias with dedicated tooling, and generate PRISMA flow diagrams for publication. A strong emphasis on auditability and transparency means every decision is traceable and reproducible. An API is available to extend Rayyan beyond the interface, and pricing runs from a generous free tier for basic use up to enterprise plans for institutional research programs.

**Pricing & Plans:** Free forever for basic use with no credit card required, making core screening and deduplication accessible to individual researchers. Paid and enterprise plans unlock advanced capabilities such as ResearchPilot, Risk of Bias, and institutional features; pricing details are available on the site and through sales.

- **Automatic deduplication:** The Systematic Auto-Resolver deduplicates up to 200,000 references using your own inclusion and exclusion protocol with one click.
- **ResearchPilot AI:** ResearchPilot delivers zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and auto-extraction to speed up search, screening, and data capture.
- **Screening and conflict resolution:** Work through title, abstract, and full-text screening with inclusion and exclusion tagging, conflict resolution, and blinded reviewer modes.
- **Data extraction and PRISMA reporting:** Capture structured study data with configurable extraction fields, apply PICO frameworks, and export results with auto-generated PRISMA diagrams.
- **Collaboration and scalability:** Randomly sample subsets, divide workloads, manage roles, and screen offline via the mobile app, with full audit trails for reproducibility.

**Strengths:** Covers the full systematic review workflow from import to PRISMA export; ResearchPilot AI speeds up search, screening, and extraction; Deduplicates up to 200,000 references from your own protocol; Offline-capable mobile app for screening anywhere

**Limitations:** Full-text screening workflows still demand significant reviewer time; Some advanced AI capabilities are aimed at enterprise and institutional plans; Requires structuring your review protocol to get the most from automation
