| Spec score · AI Diagram Generators | 9.0 (#4) | 9.1 (#3) |
| Architecture diagrams | The visual editor supports UML classes, interfaces, components, databases and services with drag-and-drop editing and undo/redo. | It generates architecture diagrams using real GCP, AWS, Azure, Databricks and Snowflake icons with automatic layout. |
| Documentation depth | The product advertises Markdown documentation with categories, live preview and AI generation, but no separate public developer documentation was found. | The documentation includes overview, getting started, pricing, authentication, posts, diagrams, brand/assets, tools/batch, errors and MCP reference sections. |
| Integrations | The service lists Stripe for payments, OpenAI for AI, GitHub and Google for authentication, and Resend for email. | The hosted MCP server connects with Claude Code, Claude Desktop, claude.ai, VS Code, Cursor, Google Antigravity, Google ADK agents and other MCP clients. |
| Intended users | The Free plan is positioned for personal projects and exploring Archflow, while Pro is positioned for teams building software together. | Capci describes itself as built for humans and callable by AI agents, and its pricing positions Pro for daily creators and Developer for teams, agencies and API integrations. |
| Security | The privacy policy says passwords are bcrypt-hashed, data in transit uses TLS/HTTPS, and production access is restricted to authorised personnel. | API keys are shown only once when created, Capci says it does not store them in plain text, and creating a new key invalidates the previous key. |
| What it does | Archflow is a SaaS workspace for collaboratively designing software architecture with AI-generated diagrams, user stories, scope cards and technical documentation. | Capci turns one-line prompts into on-brand diagrams, social graphics, charts and animations. |

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.
Capci
Capci turns one-line prompts and supplied data into diagrams, charts, social posts, and other visual content. Its architecture diagrams can use real GCP, AWS, Azure, Databricks, and Snowflake icons with automatic layout. Prompt-generated diagrams include flowcharts, sequence and class diagrams, ER schemas, mindmaps, and Gantt charts. More than 20 social and marketing formats can be chosen from a prompt or selected directly. Bar, line, donut, and KPI-tile charts are generated deterministically from supplied data without a prompt. Users can save a brand profile and export visuals as PNG or animated GIF; architecture diagrams also support SVG export. Capci provides a REST API and remote MCP endpoint, and says every plan includes API and MCP access. Free use shares a lifetime pool of 50 generations across the web app, API, and MCP. Pro is ₹375 a month, billed ₹4,499/year including GST, and Developer is ₹2,083 a month, billed ₹24,990/year including GST. Both offer monthly API and MCP generation allowances. Enterprise pricing is available by contacting sales.
