In their own words
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.

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.
