LitSynth vs Rayyan: choose screening governance or review provenance
Rayyan is the stronger choice for mature multi-reviewer screening governance, including blind screening, conflict resolution, ResearchPilot AI review, and Auto Extraction. LitSynth is the more focused choice when the deliverable must connect the research question, candidate set, screening decisions, evidence cards, cited synthesis, and review provenance in one inspectable package.

Rayyan and LitSynth by workflow stage
| Task | Rayyan | LitSynth |
|---|---|---|
| Primary job | Collaborative review governance and evidence operations | Traceable workflow from question and screening to cited synthesis |
| AI-assisted screening | ResearchPilot AI Reviewer and AI Analyzer provide criteria-based decisions with reasoning | Criteria-based recommendations with reasons, uncertainty, and human override |
| Reviewer governance | Blind screening, multiple reviewers, conflicts, and reconciliation workflows | Single-reviewer with AI assistance; no dual-reviewer conflict workflow |
| Evidence extraction | ResearchPilot Auto Extraction fills reviewer-defined forms from PDFs | Structured evidence cards and evidence tables feed the final synthesis |
| Audit boundary | Decision reasoning, reviewer actions, conflicts, and extraction approvals inside the review workspace | Candidate set, decisions, included set, evidence cards, citation audit, and generation manifest in an exportable provenance pack |
| Final deliverable | Structured review data, extraction tables, and governed team workflow | Evidence table, cited narrative draft, citation-quality report, and provenance archive |
Choose Rayyan if…
- Your protocol requires dual independent screening with conflict resolution.
- Your institution already standardizes on Rayyan and ResearchPilot.
- Your team prioritizes mature collaboration, blind mode, and reviewer reconciliation.
Choose LitSynth if…
- You need screening, evidence extraction, and a cited draft connected in one workflow.
- You want to archive the candidate set, decisions, evidence cards, citation audit, and generation version together.
- You want public screening benchmark artifacts that expose false exclusions.
- You are doing a rapid or PRISMA-lite review without dual-reviewer requirements.
This comparison helps when
- Comparing collaborative screening governance with evidence-to-draft provenance
- Teams that need screening decisions to remain connected to the final synthesis
- Reviewers evaluating AI assistance without treating either tool as autonomous
What it cannot decide for you
- Replacing Rayyan dual independent screening or conflict resolution
- Claiming that either product removes the need for reviewer validation
Frequently asked questions
Should I replace Rayyan with LitSynth?
Not necessarily. Rayyan is the stronger fit when your protocol requires dual independent screening, blind mode, and conflict resolution. LitSynth is the stronger fit when a single-reviewer or rapid-review workflow needs the evidence trail to continue into a cited synthesis and exportable provenance archive.
Does Rayyan include AI screening and data extraction?
Yes. ResearchPilot includes AI Reviewer and AI Analyzer for criteria-based screening with reasoning, plus Auto Extraction for reviewer-defined fields. Any comparison that says Rayyan only supports manual labels or has no extraction is outdated.
Does LitSynth support dual screening like Rayyan?
No. LitSynth provides AI-assisted screening with stated reasons and human override, but it is not a dual-reviewer screening platform. For formal systematic reviews requiring dual independent screening, use Rayyan or Covidence for that step and LitSynth for extraction and synthesis.
Are Rayyan AI screening decisions inspectable?
Yes. ResearchPilot exposes criteria-based decisions and detailed reasoning, and reviewers remain responsible for validation. Rayyan emphasizes team screening governance, while LitSynth emphasizes evidence-to-draft traceability and an exportable provenance record.
