In their own words
Archflow
Archflow is a web platform for collaboratively designing software systems with AI. Its assistant can create architecture diagrams, user stories, scope cards, and technical documentation from natural-language input. The visual editor supports UML classes, interfaces, components, databases, and services, with drag-and-drop creation and undo/redo. Teams can edit together using synchronized changes, live cursors, presence indicators, comments, and activity feeds. Kanban boards track user-story status, estimates, and acceptance criteria, and link stories to architecture diagrams. Documentation is created in a Markdown editor with live preview and categories, and can also be AI-generated. The Free plan costs nothing and allows one project and three diagrams per project. Pro costs $5 a month and includes unlimited projects and diagrams, AI-generated content, real-time collaboration, and priority support. Archflow says prompts and selected project context are sent to OpenAI's API, and AI chat history is stored on its servers.
Eraser
Eraser is a diagramming tool for technical teams that generates diagrams from prompts, code, files, and private Git repositories. It supports flow charts, entity-relationship diagrams, cloud architecture diagrams, sequence diagrams, and BPMN diagrams. Generated diagrams can be adjusted with diagram-as-code or AI edits, and reference libraries can align output with company building blocks. Collaboration includes real-time work, comments, tagging, and unlimited free guests. The service lists GitHub, Notion, Confluence, and a VS Code extension, as well as live diagram embeds and Git-powered updates. The free plan includes 3 files, 3 AI diagrams, and 7-day version history. Starter costs $15 a month when billed annually, or $20 monthly; it adds unlimited files, private files, and API calls. The diagram API is for paid users, while MCP operations are subject to plan AI-credit limits. Eraser says it is SOC 2 Type 2 certified, performs annual penetration testing, and does not train AI models on customer content. Enterprise deployment options include multi-tenant, single-tenant, and self-hosted setups.
