## Eraser

Eraser is a technical design platform aimed at the people who document architecture: enterprise architects, DevOps and platform engineers, consultants, and software teams. The core promise is speed without sloppiness, so instead of dragging boxes for hours you describe the system or point Eraser at a source of truth such as code, a cloud account, a CMDB, or a spreadsheet, and it produces a diagram that already follows sensible layout rules.

Beyond static images, Eraser supports interactive maps that zoom from a company-wide view down into a single service, guided explainers that walk teammates through a system, and AI documents for design docs and technical documentation. Team governance features such as shared style presets, naming rules, and reference architectures keep output consistent as more people create diagrams. An open-source agent toolkit and MCP server let tools like Claude, Cursor, and ChatGPT create, search, and export diagrams programmatically.

Prices are organized in tiers that include a free entry point, paid plans, and enterprise agreements, with multi-tenant, single-tenant, and self-hosted deployment options for larger organizations. Security posture includes SOC 2 Type 2 certification and SAML SSO.

**Pricing & Plans:** Freemium with paid plans and custom enterprise pricing. A free tier and free tools such as DiagramGPT are available, while paid individual and team plans plus enterprise agreements cover advanced governance, security, and deployment options; check the pricing page for current rates.

- **AI diagram generation:** Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
- **Maps from live systems:** Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
- **Diagram-as-code integrations:** Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
- **Open-source agent toolkit and MCP server:** Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
- **Team style governance:** Apply presets, naming and notation rules, and reference architectures so every teammate's diagram ships on-brand and consistent.

**Strengths:** Turns prompts, code, and files into properly laid-out diagrams instead of raw box-and-arrow output; Interactive maps and explainers make complex systems understandable to non-architects; MCP server and open-source toolkit fit agent-driven and self-hosted workflows; Enterprise controls such as SSO, SAML, and SOC 2 Type 2 certification

**Limitations:** Heaviest value comes with team and governance features that need setup; Advanced mapping and self-hosted deployment are aimed at larger organizations rather than solo users

## Rayyan

Rayyan is a dedicated platform for systematic literature reviews and evidence synthesis, used by more than a million researchers at tens of thousands of institutions across over 190 countries. Rather than being a general reference manager, it maps directly onto the standard review pipeline: importing references from multiple sources, organizing them into a library, inviting collaborators with defined roles, deduplicating the corpus, and then working through title and abstract screening followed by full-text screening with conflict resolution.

The AI layer centers on ResearchPilot, which provides zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and automated data extraction designed to be dramatically faster than manual workflows. Rayyan also ships a Systematic Auto-Resolver that can deduplicate up to 200,000 references based on your own protocol in a single action, plus a mobile app that lets reviewers screen studies on the go or even offline. Small productivity touches like programmable hot keys and randomized data sampling help teams divide large workloads without losing coordination.

Beyond screening, Rayyan covers the back half of a review too. Teams define structured data extraction fields, apply PICO frameworks to structure evaluation, capture study-level data, assess Risk of Bias with dedicated tooling, and generate PRISMA flow diagrams for publication. A strong emphasis on auditability and transparency means every decision is traceable and reproducible. An API is available to extend Rayyan beyond the interface, and pricing runs from a generous free tier for basic use up to enterprise plans for institutional research programs.

**Pricing & Plans:** Free forever for basic use with no credit card required, making core screening and deduplication accessible to individual researchers. Paid and enterprise plans unlock advanced capabilities such as ResearchPilot, Risk of Bias, and institutional features; pricing details are available on the site and through sales.

- **Automatic deduplication:** The Systematic Auto-Resolver deduplicates up to 200,000 references using your own inclusion and exclusion protocol with one click.
- **ResearchPilot AI:** ResearchPilot delivers zero-shot relevance ratings, an AI Analyzer, an AI Reviewer, and auto-extraction to speed up search, screening, and data capture.
- **Screening and conflict resolution:** Work through title, abstract, and full-text screening with inclusion and exclusion tagging, conflict resolution, and blinded reviewer modes.
- **Data extraction and PRISMA reporting:** Capture structured study data with configurable extraction fields, apply PICO frameworks, and export results with auto-generated PRISMA diagrams.
- **Collaboration and scalability:** Randomly sample subsets, divide workloads, manage roles, and screen offline via the mobile app, with full audit trails for reproducibility.

**Strengths:** Covers the full systematic review workflow from import to PRISMA export; ResearchPilot AI speeds up search, screening, and extraction; Deduplicates up to 200,000 references from your own protocol; Offline-capable mobile app for screening anywhere

**Limitations:** Full-text screening workflows still demand significant reviewer time; Some advanced AI capabilities are aimed at enterprise and institutional plans; Requires structuring your review protocol to get the most from automation
