Covexe

Covexe is a browser-based platform for systematic reviews, meta-analysis, evidence synthesis, and applied statistics. Its review workflow covers research questions and searches, screening, full-text review, extraction, appraisal, synthesis, and reporting. It supports review types including systematic, scoping, rapid, umbrella, narrative, network meta-analysis, and diagnostic accuracy reviews. Methods include pairwise and network meta-analysis, GRADE ratings, risk-of-bias tools, and a PRISMA 2020 flow diagram. The statistics suite covers regression, survival analysis, diagnostic accuracy, and other methods checked against R packages and implementations. References can be imported in RIS, NBIB, BibTeX, PubMed XML, CSV, and Excel formats, with duplicates detected by DOI and PMID. Users can connect their own OpenAI, Anthropic, or Google AI key. The co-pilot pauses at approval checkpoints, and AI screening will not exclude a study without approval. The Free plan is free; Pro is $99 a year. Signed-in reviews are stored for cloud sync and sharing.

Covexe brings review workflows, statistical methods, reference imports, and AI features into a browser-based platform. Its free tier has limits on library size, extraction, screening, and reviewers; Pro is listed at $99 a year.

Covexe is aimed at evidence-synthesis researchers and organizations such as universities, research laboratories, public health institutes, hospitals, and independent researchers. Its review workflow and statistics tools may suit people conducting several kinds of evidence review.

Covexe combines systematic review management with meta-analysis and applied statistics in a browser-based platform. It is best suited to evidence-synthesis researchers who want screening, extraction, appraisal, and analysis in one workspace. The free plan works for a small project, while larger libraries and review teams need a paid tier.

Overview

Covexe follows a review from question and search through screening, full-text review, extraction, appraisal, synthesis, and reporting. It supports systematic, scoping, rapid, umbrella, and narrative reviews, along with network meta-analysis and diagnostic accuracy reviews. That range makes it a strong fit for researchers handling different evidence-synthesis formats; its browser-only platform is a narrower choice for anyone who needs a desktop or mobile app.

Reference imports accept RIS, NBIB, BibTeX, PubMed XML, CSV, and Excel files, and duplicates are detected by DOI and PMID. Double-blinded screening, protocol support, extraction, and full-text storage cover core review tasks. The free library holds five papers and each review allows one reviewer, so it is better for an individual pilot than a substantial collaborative project.

Key features

For analysis, Covexe includes pairwise and network meta-analysis, GRADE ratings, risk-of-bias tools, and a PRISMA 2020 flow diagram. Its broader statistics suite adds regression, survival analysis, and diagnostic accuracy methods, checked against R packages and implementations. This breadth can reduce the need to move between separate review and statistics tools, though researchers should still choose methods that suit their study design.

AI features use a user's own API key from OpenAI, Anthropic, or Google. The co-pilot pauses at checkpoints for approval, and AI screening cannot exclude a study without that approval. These controls keep decisions with the reviewer, while the provider connection means AI use sends inputs to the selected provider for processing. Covexe says those inputs are not retained on its servers afterward.

Signed-out work stays in the browser; signed-in reviews are stored for cloud sync and sharing. Covexe says it does not use tracking or advertising cookies or third-party analytics scripts. Email support at [email protected] is stated to reply within 1–2 business days.

Pricing

The Free plan costs nothing, billed forever. It includes all tools, 100 AI co-pilot messages per day, extraction for 40 studies per month, screening for 2,000 references per month, a five-paper library, and one reviewer per review. Those caps make it practical for trying the workflow or managing a small solo review, but the library and reviewer limits arrive quickly in ongoing research.

Pro costs $99 a year, billed yearly. It raises the library to 100 papers and allows up to five reviewers per review, with extraction for 1,500 studies per month, screening for 5,000 references per month, AI advisor and figures at 200 per month, and 15 agent reviews per month. It is the more suitable individual or small-group plan when the free library or screening quota is too restrictive.

Team costs $150 a year per seat, billed yearly, with a minimum of 3 seats. It supports up to 25 reviewers per review, a 1,000-paper library, and shared AI quotas of 5,000 extractions, 20,000 screened references, and 50 agent reviews per month. The minimum commitment makes it a team purchase rather than a modest upgrade for one researcher. Institution has custom pricing and allows unlimited reviews and projects, up to 100 reviewers per review, and an unlimited PDF library; it suits organizations needing those larger shared limits.

Platforms

Covexe runs on the web. Its maker, Covexe Labs, is an independent software team based in Taipei, Taiwan.

Who it's for

Covexe is aimed at evidence-synthesis researchers and organizations such as universities, research laboratories, public health institutes, hospitals, and independent researchers. It is a particularly good match for users who need both review-stage management and statistical methods, and who can work within the library and monthly usage limits of their chosen plan.

Pros and cons

Pros

• One platform covers the review lifecycle and statistical analysis: screening, extraction, appraisal, synthesis, reporting, meta-analysis, and other methods sit in the same browser workspace.
• Broad reference import support: six file formats and DOI/PMID duplicate detection help researchers bring in varied reference libraries.
• AI decisions retain reviewer approval: checkpoints and approval before exclusion keep screening decisions under human control.

Cons

• The free tier is tightly capped for collaboration: its five-paper library and one-reviewer limit constrain even a small shared review.
• Team starts with three paid seats: the yearly per-seat price and minimum make it a poor fit for a single researcher who needs more than Pro allows.
• AI processing involves an outside provider: users must connect a provider key, and AI inputs are sent to that provider for processing.

Alternatives

For a different fit, consider Rayyan, whose free plan allows three active reviews and two free reviewers and includes limited mobile app access; it is a better match for users who value mobile availability or need more than one free reviewer. HAWC is free for exploring public assessments, while creating assessments requires requesting an account, making it the choice for readers focused on public assessments.

Parsifal offers free web access and an optional AI assistant using your own Anthropic or OpenAI API key. ReviewAid is an open-source option under Apache 2.0, with web, desktop, and self-hosted platforms. RevMan is another freemium option, with a free trial and Linux, macOS, web, and Windows support.

Silvi has a free Basic plan with unlimited reviews, screening, and data extraction, so it may suit users whose priority is an unrestricted number of reviews. Systematicly has a free Explorer tier for three active personal drafts, one lifetime feasibility preview, and three lifetime Evidence Answers. Bango is free for any researcher, with no subscription, paywall, or limits, and is available for Linux, macOS, and Windows.

Verdict

Covexe is a compelling fit for evidence-synthesis researchers who want review workflows, reference handling, and statistical analysis together, with human approval built into AI screening. Choose Pro when a solo researcher or small group needs a larger library and reviewer allowance; Team and Institution address larger collaborations. Look elsewhere if you need mobile access, an unrestricted free library, or a free plan suited to multiple reviewers.
