Bango vs Rayyan

Bango automates abstract screening for systematic literature reviews by assessing articles against criteria users define. Its AI screening returns decisions along with reasoning, matched rules, suggested tags, and confidence scores. Projects can import RIS and BibTeX files or Zotero collections, with up to 10,000 articles supported per project. Bibliometric analysis includes co-authorship networks, citation graphs, keyword maps, publication timelines, author rankings, and co-citation analysis. Bango can produce PRISMA 2020 flow diagrams from record counts and export them as SVG or PNG. It also supports Zotero import and export and can generate Boolean search strings for several research indexes and libraries. The maker says project data stays on the user's computer, with no cloud uploads, login, or account required. The README describes locally encrypted API keys and backups that omit credentials. AI connections include hosted providers such as OpenAI, Anthropic, Google Gemini, Mistral AI, and z.ai, as well as local and other OpenAI-compatible endpoints. Bango runs on Linux, macOS, and Windows, though macOS builds support Apple Silicon only. The Free plan is free, with no subscription, paywall, or limits.

Rayyan is a platform for teams carrying out systematic evidence reviews, with workflows intended to be transparent, auditable, and reproducible. Its process spans reference import, collaboration, deduplication, title and abstract screening, full-text screening, data extraction, risk-of-bias assessment, and reporting. ResearchPilot AI Reviewer screens articles against criteria set by the user and gives decisions with reasoning notes. The Analyzer suggests inclusion or exclusion with justification, while the researcher retains final decision-making. ResearchPilot can also extract answers to custom questions from PDFs and metadata, highlight relevant passages, and let users inspect the answers. References are imported from exported files rather than a direct database connection. The API offers programmatic access to reviews, references, decisions, and metadata, plus workflow automation and external integrations. Rayyan is available on Android, iOS, web, and through an API. The Free plan allows three active reviews and two free reviewers; paid options start at $8.33 a month per seat, billed annually. Free mobile access is limited; Essential and higher provide unlimited mobile access.
