Diagram & MindMap GPT: PRO Edition is a Custom GPT for ChatGPT listed in the GPT Store. It was published by independent creator Josh Brent N. Villocido, a Philippines based builder who has shipped more than two hundred and fifty Custom GPTs across categories such as productivity, design, prompt engineering, and creative tooling. WIRED profiled Villocido in 2024 as one of the more prolific non US creators on the platform, and noted that he kept building GPTs even after OpenAI's revenue share program excluded creators outside the US. The PRO Edition naming on this listing suggests it is the more capable variant in a small family of diagramming GPTs by the same author.
The GPT is positioned as a visualization assistant. A user describes a system or an idea in plain language, and the assistant returns a diagram, a mindmap, a userflow, a chart, or a sequence diagram, often with a link to a drag and drop editor where the output can be tidied up before export. The store description sums it up in one line: "Visualize Code, Build Mindmaps, Generate & Edit Userflows, Charts & sequences. Drag-N-Drop Edit."
The assistant sits in a busy category of GPT Store tools that combine LLM text generation with diagramming syntaxes. Rather than asking a user to learn a markup language like Mermaid or PlantUML by hand, the GPT lets the user describe a concept conversationally. The model writes the underlying syntax and returns either an embedded preview or a link to an external editor where the diagram can be tweaked further. This pattern appears across many diagramming GPTs and was one of the more popular store categories during the first year after launch.
The GPT Store launched on January 10, 2024, several weeks after OpenAI first introduced Custom GPTs at its November 2023 DevDay event. According to TechCrunch's coverage of the launch, the store became a directory where any ChatGPT Plus, Team, or Enterprise subscriber could publish a tailored version of GPT-4 with custom instructions, optional knowledge files, and optional tool access. Diagram and mindmap GPTs were among the most active early submissions because the use case is concrete, the value shows up clearly in a screenshot, and the underlying conversion task (text to diagram syntax) plays to the strengths of an LLM trained on lots of code and documentation.
Villocido's catalog spans mindmaps, prompt engineering helpers, 3D modeling helpers, rewriting utilities, logo generators, and topic specific tutors. The PRO Edition listed here is one of several diagramming GPTs in his catalog. The store does not publish the system prompt for a given Custom GPT, so the precise behavior differences between PRO Edition and any non PRO siblings are not directly visible. From the outside, the most useful signal is the store description, the listed conversation starters, and the experience of running a few prompts through the tool.
The official store description lists five practical jobs the GPT is meant to handle. Each one maps to a standard diagram family.
| Capability | Typical use |
|---|---|
| Visualize code | Take a function, class, or repository description and produce a class or component diagram so the structure is easier to read at a glance. |
| Build mindmaps | Turn a topic, outline, or brainstorming dump into a hierarchical mindmap with branches and sub branches for further thinking. |
| Generate userflows | Convert a product idea or a user story into a userflow showing screens, decisions, and actions. |
| Charts | Produce simple charts (pie, bar, and gantt style) for quick reporting or planning. |
| Sequences | Render sequence diagrams for protocols, API calls, or step by step processes between actors. |
The "Drag-N-Drop Edit" line refers to the editor link the GPT typically returns alongside its output. When a Custom GPT in this category produces a diagram, it commonly emits a shareable URL pointing to a third party editor (Mermaid Live Editor, draw.io, Excalidraw, or similar) where the generated source can be moved, restyled, or exported as PNG, SVG, or PDF. The GPT itself runs entirely inside the ChatGPT interface and does not draw the diagram pixel by pixel. It writes the markup and hands editing off to a tool that already understands that markup.
Like every Custom GPT, this one runs on top of GPT-4 and inherits the standard ChatGPT chat surface. The configuration consists of a name, a profile picture, a short description, a longer system prompt that steers tone and behavior, an optional set of starter prompts, optional uploaded knowledge files, and a list of enabled tools (web browsing, DALL-E image generation, code interpreter, and custom Actions). The store does not publicly expose which of these toggles a given GPT has enabled, so users see only the description, the rating, and the conversation when they open it.
In practice, a session with this GPT looks something like the following. The user asks for a diagram in plain English. The model interprets the request, picks a diagram type that matches (mindmap, sequence, flowchart, class, gantt, and so on), writes the diagram source in a language such as Mermaid, and returns it inside a fenced code block. ChatGPT can render Mermaid blocks inline in some clients, and the GPT typically also returns an editor URL so the user can click through, adjust nodes, and export the final image. If the user asks for a revision, for example "add a step between login and dashboard" or "split the marketing branch into three sub branches", the model rewrites the source and returns a new render.
This pipeline works well because Mermaid syntax is reasonably forgiving and very widely represented in LLM training data. The same approach drives most of the diagramming category in the GPT Store, including the Mermaid team's own official GPT and the Show Me Diagrams plugin used by the earlier ChatGPT plugin system.
Diagram and mindmap GPTs in this category usually cover roughly the same vocabulary. The exact list for this GPT is not publicly published, but the description names the major families clearly. Typical outputs include:
These map closely to the diagram types that Mermaid and PlantUML support natively, which is why so many diagramming GPTs settle on the same menu. The Mermaid project specifically lists flowchart, sequence, class, state, git graph, C4, block, gantt, timeline, sankey, user journey, entity relationship, pie chart, requirement, quadrant chart, mindmap, and XY chart diagrams in its documentation.
The practical audience tends to be wide. Software engineers use these GPTs to sketch architecture and document existing code without leaving the chat window. Product managers use them to draft userflows during early discovery. Students and teachers use them to turn long readings into mindmaps that compress the structure of an argument. Founders and consultants use them to draft pitch deck visuals or process maps before handing the file off to a designer.
Because the GPT runs inside ChatGPT, it is also a fast scratchpad. A user can describe a system in two sentences, see a draft diagram, then iterate verbally rather than wrestling with diagram software directly. The drag and drop editor link gives a way out when the chat reaches the limit of how precisely a user can describe layout in words. Many users keep the chat open for ideation and switch to the editor for final polish.
Diagram & MindMap GPT: PRO Edition is one option in a crowded category. Three reference points are worth comparing because they cover the main approaches taken by other tools in this space.
| Tool | Built by | Primary engine | Notable strengths |
|---|---|---|---|
| Diagram & MindMap GPT: PRO Edition | Josh Brent N. Villocido (independent) | GPT-4 with Mermaid style output and external editor links | Broad diagram coverage in a single Custom GPT, simple drag and drop editor handoff |
| Whimsical Diagrams | Whimsical (company) | GPT-4 with Whimsical's own rendering engine and canvas | Native flowcharts, mindmaps, sequence diagrams, wireframes, and whiteboards, with diagrams that open directly inside the Whimsical app |
| Diagrams: Show Me | redstarplugin.com | GPT-4 with Mermaid, D2, nomnoml, and Graphviz | Multiple diagram languages in one tool, useful when a user wants something other than Mermaid |
| Mermaid Chart GPT | Mermaid Chart team | GPT-4 with Mermaid syntax and the Mermaid Chart Editor | Official mapping into the Mermaid Chart product, with all Mermaid diagram types supported |
A few practical differences fall out of this lineup.
Whimsical's integration is the most polished if a team already uses Whimsical for design work. According to the Whimsical help center, the app supports flowcharts, mind maps, sequence diagrams, wireframes, and whiteboards, and it can search existing Whimsical boards from inside ChatGPT to pull up past work. The downside is that the diagrams live inside Whimsical rather than as plain Mermaid text that a developer can paste into a README.
Show Me Diagrams was originally one of the most installed plugins in the older ChatGPT plugin system before OpenAI consolidated plugins under Custom GPTs and Actions. It supports several diagram languages, with Mermaid as the default. Its main advantage is breadth of syntax: if a user has a preference for D2 or Graphviz, Show Me will honor that without making the user manually convert.
Mermaid Chart's own GPT is the closest analogue to PRO Edition in terms of output format, since both lean on Mermaid syntax. The Mermaid Chart variant is published by the team behind the spec, so any new diagram type added to Mermaid lands in their GPT first. PRO Edition trades that tight coupling for being a single Custom GPT inside the GPT Store, which is easier to discover for casual users who do not already know what Mermaid is.
Diagram & MindMap GPT: PRO Edition occupies the same general slot as these tools without being tied to any specific commercial canvas. For users who do not have a Whimsical account and do not particularly care which diagram language sits underneath, the all in one Custom GPT format is usually easier to start with. For teams that have a strong preference (already on Whimsical, or already storing diagrams as Mermaid in git), one of the more specialized tools may fit better.
A few caveats apply to this GPT and to the broader category. Output quality depends on how clearly the user describes the system; vague prompts produce vague diagrams. The GPT does not store private data between sessions unless the user explicitly enables ChatGPT memory, so each new conversation starts fresh. Complex diagrams with many nodes can hit token or rendering limits, in which case the user usually has to break the diagram into smaller pieces. The underlying syntax (Mermaid or otherwise) is itself an evolving spec, and not every requested diagram type is supported by every editor. Layout is also a known weak point: even when the syntax is correct, automatic layout algorithms can produce crossed edges or awkward spacing that needs manual cleanup in the editor.
The "Updated" field on this entry shows a placeholder date and the chat counter reads zero, which suggests the listing was either newly created at import time, never gathered live usage stats from the store API, or has since been renamed. The direct OpenAI URL for the GPT also returns a 404 at time of writing. Users looking for an active equivalent can search the GPT Store directly for terms such as "mindmap", "diagram", or "flowchart" and pick a GPT with a recent update date and a healthy chat count, or fall back to the Whimsical, Show Me, or Mermaid Chart options listed above.
