EviSynth vs Litmaps

EviSynth is a platform for evidence syntheses and systematic reviews, available on Android, iOS, and the web. Its screening workflow uses a language model to assess abstracts against PICO criteria and suggest inclusion or exclusion. Built-in risk-of-bias tools support RoB 2, ROBINS-I, and custom checklists. Teams can invite collaborators, resolve conflicts, and track who screened each item and when. The AI Insights tab provides summaries, keyword extraction, and bias hints. References can be imported as EndNote XML or PubMed NBIB files, and the screening interface is designed for touch-screen use on mobile devices. The maker describes access as free for academic use, with no trials or subscriptions, and says no credit card is required to start. The platform is open source and presented for researchers, including students and faculty conducting rapid or full systematic reviews. The listed academic plan includes unlimited collaborators. The homepage credits Milad Mirmoghtadaei, M.D. as developer.

Litmaps is a web-based research tool that uses citation networks and advanced search to help researchers find papers and conduct literature reviews. Its search catalogue contains more than 270 million papers. A Litmap visualizes connections among articles through citations and references; users can annotate papers and change how the map is arranged. Topic monitoring sends automatic emails when new articles appear, and maps can be shared as images, public links, or with selected email addresses. The free plan costs nothing and includes basic search, up to 20 inputs and 100 articles, one Litmap, and a monthly summary, but no collaboration. Pro (Education) costs $10 a month, billed $120 / year - save 20%; it adds advanced search, unlimited inputs, articles, and Litmaps, plus daily or configurable alerts, and requires an academic email address. Litmaps Pro syncs Zotero collections with Litmaps Tags in both directions. Articles can also be imported from BibTeX, RIS, or PubMed files and exported in BibTeX, RIS, or CSV formats. Open Access PDFs are available to all users; other PDF access requires institutional access through LibKey.
