## 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

## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity
