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.
