Systemic Review on systematic-review.app — upload your screening list, retrieve open-access full texts through legal public APIs, and export audit-ready files for EndNote. No scripts, no guesswork.
Built for Master's students, doctoral candidates, faculty, and clinician–researchers. Processing respects open-access policy and your institution's norms.

Upload Covidence/EndNote export (CSV or JSON). We normalize DOIs, study numbers, and author stubs to match common file naming (e.g. 003_Author_2020.pdf).
For each DOI, we query Unpaywall, then Europe PMC, then PubMed Central when a PMC ID is available. Paywalled articles are flagged for library or author follow-up — never pirate sources.
Record inclusion and exclusion criteria. Optional keyword hints support PDF text review — they do not replace your judgment.
CSV for supervisors, EndNote-style XML for reference managers, and a download log showing which resolver succeeded for each article.
This app does not scrape paywalled publisher sites or bypass login walls. We use official public APIs and open-access indexes so your methods section can name real sources.
| Source | What it does | Access model |
|---|---|---|
| Unpaywall | Maps DOIs to legal open-access PDF or landing-page URLs | Open API; requires user's institutional email per Unpaywall policy |
| Europe PMC | European open biomedical literature; PDF links and PMC mirrors | Open REST API (EMBL-EBI) |
| PubMed Central | NIH open-access full-text archive when PMCID is known | Open PDF endpoints via Europe PMC render |
| PubMed (NCBI E-utilities) | Literature search (esearch + esummary) | Open; optional NCBI API key for higher rate limits |
| Source | What it does | Access model |
|---|---|---|
| ClinicalTrials.gov API v2 | US trial registry — NCT IDs, design, status, locations | Open JSON REST (NLM) |
Strips https://doi.org/ prefixes, trailing punctuation, and whitespace so lookups are consistent across export tools.
Removes characters unsafe on Windows/macOS (<>:"/\|?*), collapses whitespace, caps length — batch exports work on every lab machine.
Covidence #3, 003, and 3 resolve to the same row for matching PDFs on disk.
Unpaywall → Europe PMC by DOI → Europe PMC by PMC ID → clear status if no legal OA PDF exists.
Extracts text locally up to page/character limits; counts protocol keyword hits — advisory only, not automated inclusion decisions.
We do not request, store, or process PHI or patient-identifiable data. Uploaded study lists should contain bibliographic metadata only.
Stop manually opening publisher pages, checking Unpaywall one article at a time, and renaming PDFs to match your Covidence numbers. Batch retrieval with a source-labeled audit log means you spend time on appraisal — not tab archaeology.
No terminal, no JSON editing, no "configure ingestion pipeline." Upload your list, click download, export to EndNote. Advanced options exist; they never block the first successful run.
Every success and failure is tied to a named open resolver (Unpaywall, Europe PMC, PMC) — supporting PRISMA transparency and supervisor sign-off without hand-waving about "an AI found the PDF."
“I stopped maintaining a shadow spreadsheet of which PDFs I'd already tried.”
“Students export a log I can actually read in a methods meeting.”
“Registry search and full-text retrieval in one place — finally.”
