Study Screener vs Rayyan: feature comparison for systematic review screening
A practical comparison of Rayyan and Study Screener for title/abstract screening aligned with PRISMA 2020 and Cochrane study-selection guidance: imports, blinding, AI paths, exports, and honest gaps.
Purpose. Help you decide whether Study Screener fits your title/abstract screening step—not to declare a universal “winner.” Rayyan is widely used for collaborative screening; we compare observable product behavior (May 2026 codebase) and flag gaps on both sides. Method expectations are aligned with PRISMA 2020 and the Cochrane Handbook, Ch. 4.

Quick answer (Rayyan features vs what Study Screener does)
If you need a fast read: Rayyan offers in‑app deduplication, blinded dual screening, conflict review with Blind Mode off, and flexible RIS/CSV/BibTeX exports. Study Screener supports blinded dual screening with a disagreement inbox and an owner/arbiter resolution step after opening; imports accept RIS and PubMed .txt, and the backend jointly deduplicates combined uploads (DOI or normalized title+year) before storing studies. AI assistance in Study Screener runs as a separate batch job (not inline re‑ranking). Both tools export what you need for PRISMA reporting; Study Screener also ships a standalone PRISMA 2020 diagram builder. See proofs and sources below.
Verified feature snapshot (with sources)
| Screening feature | Rayyan (source) | Study Screener (verified) |
|---|---|---|
| Import formats | EndNote .enw, RIS .ris, BibTeX .bib, CSV .csv, PubMed NBIB/XML, CIW, PDF Rayyan import formats | RIS .ris and PubMed/MEDLINE .txt accepted in UI and direct upload |

Rayyan in one paragraph
Rayyan is a web and mobile environment built for multi-reviewer title/abstract screening, with deduplication and optional machine-learning assistance while you work through the queue. Teams often choose it for low-friction collaboration. Feature sets and plans change over time—confirm current capabilities on rayyan.ai before you commit.
Study Screener in one paragraph (from the product)
Study Screener focuses on PRISMA-friendly documentation for screening (PRISMA 2020): blinded manual decisions per Cochrane norms, CSV/RIS exports with decision logs, optional batch AI classification with confidence scores, and a PRISMA 2020 diagram builder. Title/abstract screening is in-app; full-text PDF review is out of scope—plan Zotero, Covidence, or your library workflow for PDFs.

Feature comparison (verified May 2026)
Imports and deduplication
| Rayyan | Study Screener | |
|---|---|---|
| RIS import | Yes | Yes (/api/upload, AI upload) |
| EndNote XML / CSV native | Often via conversion | Convert to RIS first (Zotero, EndNote). Steps: How to import from Zotero, EndNote, or a RIS file |
| Duplicates removed on import | Rayyan UI supports detect/resolve | Yes — combined upload dedup (DOI or title+year); returns duplicatesRemoved |
| Max upload (our stack) | (Rayyan limits vary) | 50 MB direct upload |
Workflow implication: If you rely on Rayyan dedupe, reproduce it in Zotero/Mendeley/Rayyan export before importing to Study Screener, and record duplicate counts for your PRISMA 2020 flow diagram.
Manual screening UX
| Rayyan | Study Screener | |
|---|---|---|
| Decisions | Include / exclude (and extensions by version) | Include / Maybe / Exclude + notes |
| Keyboard shortcuts | Yes | I / M / E on dashboard |
| PICO highlighting | (varies) | User-defined PICO terms on abstract |
| Bulk actions | (varies) | Bulk decisions API |
| Blinding | Available | Default on; owner can unblind |
Collaboration and conflicts — see the team how‑to
| Rayyan | Study Screener | |
|---|---|---|
| Invite reviewers | Email-based teams | Email invite (owner-only API) |
| Conflict detection | Built into Rayyan UI | Team results + hasConflict when unblinded |
| Dedicated conflict‑resolve | Rayyan UI flow | Yes — owner/arbiter resolves via RPC after opening (record_decision_resolutions) |
| In-app messaging | — | Not implemented (invitation email only) |
| Per-study assignment | — | Not implemented (all reviewers share pool) |
Honest note: Cochrane expects disagreements to be resolved and documented. If your protocol requires formal third-reviewer arbitration with signed consensus notes, test whether our export + notes fields meet your audit needs in a pilot.
AI-assisted screening
| Rayyan | Study Screener | |
|---|---|---|
| Model | Prioritization / suggestions during manual queue | Batch LLM classify all records in a separate job |
| Training from your labels | Incremental while screening | Criteria text + job rerun (credits apply) |
| Confidence scores | (feature-dependent) | Per-record confidence + rationale in AI results |
See AI vs manual screening for how we describe batch AI triage vs manual dual review under PRISMA 2020.
Exports and PRISMA
| Rayyan | Study Screener | |
|---|---|---|
| Decision export | CSV / reference formats (plan-dependent) | CSV decision log, RIS by decision (manual & AI) |
| PRISMA flow diagram | Often manual / external tools | In-app PRISMA 2020 builder; AI job can pre-fill counts (verify dedupe fields) |
| Diagram formats | — | PNG / SVG (print to PDF from browser if needed) |
| Export rate limits | (Rayyan plan) | Free: 5 exports / project / 24h; AI plan: 25 (DB get_plan_policy) |
Plans and scale (Study Screener code, not marketing PDFs)
| Plan | Owned projects | Studies / project |
|---|---|---|
| Free | 1 | 10,000 |
| AI screening subscription | 5 | 20,000 |
Rayyan’s free/paid tiers change over time—confirm on rayyan.ai before budgeting.
When Rayyan is the better fit
- You want Rayyan’s deduplication and mobile workflow unchanged.
- Team is already trained and journal timeline does not justify migration.
- You need Rayyan-specific integrations your institution pays for.
- Review is small (< ~1,000 records) and migration cost exceeds benefit.
When Study Screener is worth a pilot
- You want Maybe triage, PICO highlighting, and CSV decision logs tuned for PRISMA 2020 write-ups.
- You plan batch AI triage with exported rationales (separate from manual dual review).
- You want an integrated PRISMA 2020 diagram without redrawing boxes manually.
- You are starting a new review and can dedupe once upstream.
Migration workflow: Rayyan → Study Screener
No proprietary Rayyan import—use RIS, as we document in integrations.
| Step | Action |
|---|---|
| 1 | In Rayyan, export screened or unscreened set as RIS (include decisions if exporting for audit). |
| 2 | If you need a clean restart, export search set before decisions; otherwise export with labels and map them in a spreadsheet. |
| 3 | Deduplicate in Rayyan or your reference manager if needed; Study Screener also deduplicates combined uploads on import. |
| 4 | Create a Study Screener project → upload one combined RIS. |
| 5 | Re-invite reviewers; enable blinding per Cochrane dual-screening practice. |
| 6 | Pilot 50–100 records—compare Rayyan labels vs new decisions if continuing an in-flight review. |
| 7 | Export PRISMA counts from your dedupe log + screening exports. |
Decision mapping tip: Rayyan include/exclude may map to our Include/Exclude; uncertain Rayyan items → Maybe until resolved.
Try before you switch
- Demo dashboard — manual UI, no commitment.
- Import a small RIS — test blinding and exports on a past Rayyan export.
- AI screening — run 200 records; manually audit excludes.
