Rayyan also has a mobile app and, on its Enterprise tier, an API, neither of which Covidence offers. Covidence answers back with automatic reference deduplication and a PRISMA flow diagram generated for every review, both included from its cheapest plan, plus support for six reference managers including RevMan and CRS for Cochrane style reviews, where Rayyan names none.
Pick Covidence if you need Cochrane style reference manager support built in.
Pick Rayyan if you want a mobile app and cheaper quarterly billing.

Pros and cons
From each tool's full review, written from the same checked facts.
Covidence
- Purpose-built for systematic reviews and evidence synthesis, making it highly optimized for that specific academic and clinical workflow.
- Supports unlimited collaborators on every plan, enabling large research teams to work together without user-count penalties.
- Title and abstract screening interface is fast and well-designed, reducing friction in the most time-consuming part of the review process.
- Mobile browser screening is supported, allowing co-reviewers to contribute while traveling or away from their desks.
- Trusted by over 536,000 researchers and students across more than 480 universities and hospitals, indicating strong real-world validation.
- Supports multiple import formats including RIS, CSV, and PubMedXML, making it compatible with major reference databases like PubMed.
- Conflict resolution tools are built into the screening workflow, helping teams manage disagreements systematically and according to protocol.
- No native search functionality — users must import references from external databases before any work can begin in the platform.
- AI features do not meet modern expectations, which may disappoint researchers looking for intelligent automation or AI-assisted synthesis.
- Solo reviewer pricing starts at $339 per year, which is a significant cost for individual academics or students without institutional backing.
- The tool is not useful outside of systematic review workflows, making it a poor fit for general-purpose research or literature exploration.
- Pricing and product design clearly favor institutional users, meaning solo or small-team reviewers may feel like second-class customers.
- Relies on external tools like RevMan for final output, so it does not offer an end-to-end standalone solution for evidence synthesis.
Rayyan
- The Systematic Auto-Resolver deduplicates references quickly using a configurable protocol, solving one of the most tedious parts of multi-database systematic reviews.
- ResearchPilot AI provides zero-shot relevance ratings, meaning it can score reference relevance without requiring training examples from the user.
- Auto-generated PRISMA flow diagrams save researchers hours of manual charting work.
- The AI Reviewer feature allows users to interactively query their reference set, enabling more dynamic literature exploration.
- Auto-extract data function pulls structured information from included studies, which is especially valuable in later-stage reviews.
- Over one million researchers at more than 30,000 institutions use it, reflecting genuine adoption rather than inflated free-signup numbers.
- Programmable hot keys and data sampling tools for randomized subsets help speed up screening and distribute workloads across teams.
- A free tier is available that provides meaningful functionality, including access to the deduplication feature.
- Rayyan is not listed on G2 or Capterra, making it harder to find aggregated, verified user reviews for independent evaluation.
- The tool does not perform its own database searches — users must import references manually from external sources like PubMed or Embase in RIS or BibTeX format.
- The AI-driven features are built around a proprietary system called ResearchPilot, which limits transparency into how relevance scoring and extraction decisions are made.
- It is designed for a very specific use case — systematic review screening — and is not a general-purpose research or literature discovery tool.
- Academic forum coverage is the primary source of user feedback, suggesting limited mainstream visibility and potentially slower support or feature communication.
