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.
OpenCharts
OpenCharts is an AI workspace for flowcharts, presentations, notes, code, video, and agents. Theo AI can create these materials from plain-language descriptions. Flowcharts use terminal, process, decision, and data nodes on an infinite canvas, with automatic layout and export tools. The presentation editor supports editable slides, speaker notes, transitions, AI generation, rehearsal coaching, web publishing, and PPTX export. Theo Agents can start on schedules, webhooks, monitoring triggers, or manually; they can use external connectors, human approval gates, and produce deliverables. Connectors include Stripe, HubSpot, Slack, Google Sheets, Discord, Notion, GitHub, and others. A REST API manages project types, and the Theo MCP server provides 113 tools and five readable resources. Each account starts with 10 GB of Drive storage, including Free Forever. That plan costs nothing and includes 500K AI credits and one of each project type. Starter costs $9.99 a month, Pro $24.99 a month, and Teams $14.99 a month with a three-user minimum. OpenCharts says it does not use customer data to train or fine-tune AI models.
