EviSynth

EviSynth is a platform for conducting evidence syntheses and systematic reviews, available on Android, iOS, and the web. Its language model analyzes abstracts against PICO criteria and suggests 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 EviSynth as open source and completely free for academic use, with no trials or subscriptions and no credit card required to start. Its intended users include researchers, students, and faculty conducting rapid or full systematic reviews. The homepage credits Milad Mirmoghtadaei, M.D. as the developer.

EviSynth combines abstract screening, risk-of-bias tools, and team review tracking for evidence synthesis work. Its access is described as free for academic use, and its screening interface supports touch-screen mobile use.

EviSynth suits researchers, students, and faculty conducting rapid or full systematic reviews. Its collaboration and screening tools are relevant to teams working through evidence reviews.

EviSynth is a systematic review workspace for researchers who need to screen studies and manage a shared review process. Its strongest case is a no-cost academic workflow that pairs PICO-based AI screening with established risk-of-bias tools; researchers who need a paid support tier or a different research focus should compare alternatives.

Overview

EviSynth brings reference screening, risk-of-bias assessment, and team coordination into one platform. Its language model evaluates abstracts against PICO criteria and recommends inclusion or exclusion, while AI Insights adds summaries, keywords, and bias hints. Those suggestions can help teams move through a large screening queue, but the decision remains part of a review workflow that also supports conflict resolution and tracks who screened each item and when.

The homepage describes the software as open source and credits Milad Mirmoghtadaei, M.D. as its developer. References can be imported from EndNote XML or PubMed NBIB files, giving review teams two documented routes to bring existing records into the workflow.

Key features

Screening and AI insights

PICO-based abstract screening gives reviewers a way to triage records against their review question, and the separate AI Insights tab offers summaries, keyword extraction, and bias hints. These tools address common review tasks in one place, though teams should treat suggested screening decisions and bias hints as inputs to their assessment rather than substitutes for it.

Risk of bias and collaboration

Built-in support for RoB 2, ROBINS-I, and custom checklists suits teams working with different study designs or assessment needs. Invitations, conflict resolution, and an item-by-item record of who screened and when make the shared process easier to follow. That combination is particularly useful when several reviewers need to coordinate decisions and maintain a clear screening trail.

Reference imports and mobile screening

EndNote XML and PubMed NBIB imports provide a practical start for teams with references in either format. The screening interface is designed for touch-screen mobile use, so reviewers can work through screening on a phone or tablet as well as on the web.

Pricing

EviSynth offers Free academic access at no cost. The plan includes academic use and unlimited collaborators, with no trials or subscriptions; the maker also says no credit card is required to start. For students, faculty, and research teams conducting rapid or full systematic reviews, this removes a per-seat cost from collaborative screening. No free-plan caps are stated.

There is no free trial because the academic access is free, and there are no subscriptions to renew. The stated access is for academic use, so readers choosing software for non-academic work should confirm that this fits their circumstances.

Platforms

EviSynth is available on Android, iOS, and the web. Its mobile-native, touch-screen screening interface makes mobile review work a stated part of the product, rather than simply offering a web-only workflow on a phone.

Who it's for

EviSynth is best suited to students, faculty, and research teams conducting rapid or full systematic reviews who want screening, risk-of-bias assessment, and collaboration without subscription costs. Its combination of PICO-based suggestions, named bias tools, and unlimited collaborators is a strong fit when several people need to review and reconcile records. Readers seeking a tool for broader literature discovery or a different research task may prefer one of the alternatives below.

Pros and cons

• Pro: Free academic access includes unlimited collaborators, so teams can coordinate screening without a stated per-reviewer charge.
• Pro: RoB 2, ROBINS-I, and custom checklists cover established risk-of-bias workflows as well as tailored assessments.
• Pro: Conflict resolution and per-item screening history help teams keep shared decisions accountable.
• Pro: Android, iOS, and web access, with a touch-screen screening interface, supports review work across devices.
• Con: The free access is described for academic use, which may not fit readers working outside that setting.
• Con: The screening and AI insight features focus on abstract assessment and review support; readers seeking a literature-mapping or broader discovery tool may find a more suitable fit elsewhere.

Alternatives

Literature Review Software is a useful starting point for comparing tools across the category.

• Rayyan is worth considering for reviewers who want a free plan with up to three active reviews and two free reviewers, or who need its separate Essential plan at $4.99 a month per seat.
• Elicit may suit readers focused on finding and working with papers: its Basic plan includes unlimited search across more than 138 million papers, unlimited summaries, and unlimited chat with papers, with limited Research Agent and Research Reports usage.
• RevMan is another freemium systematic review option, with a free trial and Linux, macOS, web, and Windows support.
• Bibliometrix fits readers looking for an open-source R package available on CRAN, with a Biblioshiny web interface.
• Inciteful is a free, open-source option for readers who want core tools with no stated usage limits.
• Litmaps may suit literature mapping: its free plan allows 20 inputs, 100 articles, and one Litmap, while Pro (Education) costs $10 a month.
• ResearchRabbit offers a free plan with unlimited searches across more than 310 million articles, unlimited libraries and collections, sharing, and up to 50 seed articles.
• Abstrackr is another free option for readers who want no seat limits, usage caps, or subscription.

Verdict

Choose EviSynth if you are conducting an academic systematic review and want a shared screening workflow with PICO-based AI suggestions, risk-of-bias tools, and unlimited collaborators at no subscription cost. Its clearest limitation is that the free access is academic; readers outside that use case, or those prioritizing literature mapping and discovery, should look to a more closely matched alternative.
