What it is

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.

Who it suits

Capci suits people making branded diagrams, charts, and social content from prompts or data. Its API and MCP access, along with the Developer plan positioned for teams, agencies, and integrations, may suit work that calls for those options.

Capci in depth

Read the full write-up

Capci is a prompt-led visual production service for technical diagrams, branded social material and data-driven charts. It suits creators, engineers and teams that need both browser work and programmatic generation. The broad scope is useful, but serious volume depends on a paid quota.

Overview

Capci combines diagramming, marketing graphics and chart creation in one web service. Prompts can produce technical and social visuals, while supplied data can generate charts without a prompt. A reusable brand profile is intended for recurring work, and exports cover PNG and animated GIF; architecture diagrams additionally support SVG.

Its human-and-agent design is a practical distinction. The hosted MCP server works with Claude Code, Claude Desktop, claude.ai, VS Code, Cursor, Google Antigravity, Google ADK agents and other MCP clients. A REST API and remote MCP endpoint are included on every plan, so Capci can sit inside an automated workflow rather than only a manual design process.

Key features

Diagrams and cloud architecture

Prompt-generated output includes flowcharts, sequence diagrams, class diagrams, ER schemas, mindmaps and Gantt charts. Architecture diagrams can use recognizable GCP, AWS, Azure, Databricks and Snowflake icons, with automatic layout. That combination is well suited to infrastructure documentation and presentations where platform-specific symbols matter.

Social content and charts

More than 20 social and marketing post formats are available. Capci can select a format from the prompt or let the user choose one directly, which gives marketing teams a wider starting set than a diagram-only tool. Bar, line, donut and KPI-tile charts are generated deterministically from supplied data, making the chart feature appropriate when the values—not an interpretation of them—must drive the visual.

Branding, exports and access control

A saved brand profile supports repeatable styling. PNG and GIF exports handle common publishing needs, while SVG export for architecture diagrams is valuable when a technical graphic must remain scalable. API keys are displayed only at creation, Capci says they are not stored in plain text, and making a new key invalidates the previous one. The service runs on Google Cloud.

Pricing

Free

Free costs nothing, billed ₹0/forever. It provides 50 lifetime generations shared across posts, diagrams and animations, one brand, no watermark, and API and MCP access from that same 50-generation pool. The first logo generation is free; later logo creation uses credits. This is enough to assess the range, but the shared lifetime cap makes it unsuitable for an ongoing production workflow.

Pro

Pro is ₹375 a month, billed ₹4,499/year including GST. It adds unlimited posts, diagrams and animations, 200 API and MCP generations per month, one active brand, priority generation and no watermark. There is no auto-renewal. Daily creators get a much more usable web allowance, although automated use remains bounded by the monthly 200-generation quota.

Developer

Developer is ₹2,083 a month, billed ₹24,990/year including GST. It includes everything in Pro and raises the API and MCP allowance to 900 generations per month, with priority generation and no auto-renewal. It is the clearer fit for teams, agencies and integrations whose main constraint is agent or API volume rather than browser creation.

Enterprise

Enterprise uses custom pricing and covers custom deployments, self-hosting and data-residency requirements scoped by contract. It is the plan to consider when deployment control outweighs the simplicity of the standard tiers.

Eligible unused paid features can be refunded within seven days under the refund policy. Razorpay is the current payment gateway, and TechTrapture Private Limited is identified as the operator.

Platforms

Capci runs on the web and exposes API access. Its remote MCP service extends generation to compatible desktop, coding and agent clients, but the product itself is not presented as a native desktop or mobile application.

Who it's for

Capci is a good match for technical communicators who need cloud-specific architecture visuals, marketers producing repeated branded posts, and developers embedding generation in agent workflows. Pro fits a daily individual creator; Developer makes more sense for an agency or team with substantial API or MCP demand. It is a weaker choice for occasional users who need only a few diagrams, or for buyers seeking a broad native-app ecosystem rather than a web-and-endpoint service.

Pros and cons

Pro: One service spans infrastructure diagrams, general diagram types, social formats and deterministic data charts.

Pro: Real cloud-provider icons, automatic layout and SVG architecture export support credible technical documentation.

Pro: API and MCP access is included at every tier, enabling both manual and agent-driven workflows.

Con: Free use ends after 50 lifetime creations shared across web, API and MCP, limiting it to evaluation.

Con: Paid automation is quota-based: 200 monthly generations on Pro and 900 on Developer.

Con: Only one active brand is included on both Free and Pro, which may constrain multi-brand work.

Alternatives

For a directory of comparable tools, see AI Diagram Generators.

Creately is the better pick if you need unlimited canvases and collaborators on a free plan, plus broad desktop, web, API and self-hosted platform coverage.

Lucid Train suits users who want an open-source, account-free CLI with local models or their own API keys.

ClearWork is an option for web-based work with up to 10 included read-only users and a paid Solo core-user plan.

Mermaid Chart is preferable when a free tier with three diagrams and limited AI, or an annual Plus plan with unlimited diagrams, fits the requirement.

Nimbalyst is worth choosing for MIT-licensed open-source desktop and iOS apps with no feature limits on its Individual plan.

OpenCharts is an alternative for users wanting 500K AI credits, project-type limits and Drive storage on its free tier.

Splotch fits extension and web users who need a free project with diagrams, two-way sync, sharing and export.

Archflow is another web-based diagramming alternative with a free project tier.

Verdict

Choose Capci if you want branded diagrams, social graphics and data charts in one service, especially when API or MCP generation is part of the workflow. Its main reason to look elsewhere is the constrained automation allowance—and the 50-creation lifetime ceiling on Free—so high-volume or narrowly focused diagram users may find a quota-free or more specialized alternative a better fit.

Verdict

Capci covers prompt-driven visuals and chart generation from supplied data, with exports and API/MCP access. The free pool is shared, while paid plans specify monthly generation allowances.
