AI connector for Microsoft Visio · Visio MCP server
Give your AI assistant
a pen in Visio®
Connect Claude Code, Claude Desktop, Cowork, ChatGPT Work, ChatGPT Codex, and other MCP-enabled AI assistants to Microsoft Visio. Create and edit patent figures and other technical drawings directly in Visio.
For Windows 11 · Requires Microsoft Visio
A real figure drawn in Visio through Vizspect. No edits, not sped up.
What Vizspect is
The missing link between AI and Visio, not another drawing app
Vizspect™ is an AI connector for Microsoft Visio, delivered as a local Visio MCP server. It bridges the AI assistant you already use and Microsoft Visio, with a patent draftsperson’s rules built in. You talk to your assistant the way you always do; it uses Vizspect to actually draw and edit the figure in your live Visio document.
It doesn’t replace your assistant, and it doesn’t replace Visio; it connects them. Every shape, connector, and reference numeral lands with patent-grade precision, on your machine, in the document you’re already working in.
Built for patent practice, and capable of far more wherever clean, rule-driven Visio diagrams matter.

Your live document: figures appear and update as you watch
Drawn element by element
The figures your assistant can build
Describe the figure in plain language and your assistant builds it in Visio through Vizspect™, one element at a time, each one placed, numbered, and styled to USPTO conventions.
Apparatus & block diagrams
Boxes, connectors, and a labeled system extent, placed on a fine grid and wired up with obstacle-aware connectors that route around components, not through them.
- Precise placement without relying on generic auto-layout
- Connectors route around your boxes, not through them
- Reference numbers assigned and styled for you
- Checked against the configured USPTO page margins
Claude: “draw a block diagram of the imaging system (an optical sensor, signal processor, frame buffer, system controller, memory, and output interface) with reference numerals.”
Flowcharts & decision trees
Stadium START/END, decision diamonds, and YES/NO branches that leave from different vertices with collision-aware labels: the conventions a patent flowchart needs, handled for you.
- Decision diamonds, branches, and START/END done right
- YES/NO labels placed clear of every line
- Steps numbered in order, automatically
- Crisp at any size or print resolution
Claude: “make a flowchart: detect an event, check whether it’s valid, then process and store it; otherwise discard it.”
UI mockups & interfaces
Device frames with labeled screen elements, buttons, and fields: the kind of interface figure that’s fiddly to align by hand, laid out cleanly in seconds.
- Device frames with neatly labeled elements
- Reference numerals with clean, non-crossing leaders
- Sharp 1.0pt black line art at any zoom
- Consistent, legible labels throughout
Claude: “mock up an analysis workstation: a sidebar with Overview, Reports, and Settings, a chart panel, and a Run button.”
Swimlanes & complex flows
Multi-lane process figures built in a single pass: dotted lane headers with underlined foreign element numbers, same-height cross-lane steps, and START/END, all numbered to convention.
- Multiple lanes laid out in a single step
- Clear cross-lane flow with tidy arrows
- Every element numbered without collisions
- Ask once, then refine by conversation
Claude: “build a swimlane across Intake, Analysis, Review, and Output: receive data, validate, score the event, then record the result.”
Reads your work, not just writes it
It checks your figures, too
Vizspect™ can read what’s already on the page (every shape, label, and reference numeral) so your assistant can audit and cross-check your figures against the specification, not just draw them.
Numeral consistency
Claude: “list every reference numeral in the figures and flag any that appear in the spec but not the drawings, or vice versa.”
Build the numeral table
Claude: “list each labeled element across all figures and what it’s called, so I can assemble the reference-numeral table.”
Claim coverage
Claude: “does the flowchart include every step recited in the method claim? Tell me what’s missing.”
Pre-filing check
Claude: “lint the figures for off-margin shapes, crossed leaders, and numerals that drifted off their element before I export.”
Capable of much more
Far beyond the basics
The same precise toolset handles the rest of the figures a specification needs, and general-purpose Visio diagrams too.
Swimlane charts
Cross-lane flow with numbered lane headers
Timing diagrams
Clocked waveforms from a pattern string
Org charts
Hierarchies with consistent connectors
Network diagrams
Nodes, links, and labeled topology
Process maps
Multi-step processes with clean routing
Architecture tiers
Layered systems and component stacks
State diagrams
States, directed transitions, self-loops, and reciprocal edges
Curved connectors
Automatic bowing, obstacle avoidance, and optional native Visio routing
…and most any other clean black-and-white line diagram, just by asking.
Built for patent practice
The rules of the drawing, handled
Vizspect™ knows the USPTO drawing rules and your house style, so every figure your assistant produces comes out consistent, without you policing every line and numeral.
USPTO house style, automatic
Black-and-white line art, ALL-CAPS Arial text, and 1.0pt strokes, with 37 CFR 1.84 margins enforced on every placement, portrait or landscape.
Collision-aware reference numerals
Numerals and leader lines slide along the target’s edge until nothing overlaps and no line is crossed, or the tool refuses and says exactly what’s blocking it.
Works with your AI assistant
A smart MCP server for Claude Code, Claude Desktop, Cowork, ChatGPT Work, ChatGPT Codex, and other Model Context Protocol clients that run on your machine. Any compatible client that can reach a local MCP server and call its tools can use Vizspect.
Lint & geometry checks
A read-only check flags out-of-margin shapes, overlaps, text overflow, crossed leaders, and numerals that drifted off a moved element: a pre-render gate before you file.
Edit live, alongside you
Work on the same document as your assistant. Every write re-reads the figure first, and destructive edits require explicit assertions, so your hand edits aren’t silently overwritten.
Runs entirely on your machine
The Vizspect server runs on your PC with no cloud of its own: no telemetry, and nothing sent to us. When it uses a hosted model, the AI assistant you connect sends the figure content it reads to its model provider under that provider’s privacy policy.
State diagrams & smarter routing
Build a complete state diagram in one request, with circular states, labeled transitions, self-loops, reciprocal edges, and curved connectors that route around the drawing.
Safer page control
Create, clone, reorder, resize, back up, and safely delete pages. Automatic backups and guarded renumbering provide a way back before broad changes.
Beyond the patent bar
Not just for patent lawyers
Vizspect™ was built to satisfy one of the strictest drawing standards there is: USPTO patent figures. That same precision makes it a fast, exacting drawing companion for anyone who works in Visio.
Engineers & architects
System, network, and architecture diagrams with exact placement and clean, obstacle-aware routing, not approximate auto-layout.
Technical writers & docs teams
Consistent, legible figures for manuals, specifications, and standards, generated and updated straight from your AI assistant.
Anyone who lives in Visio
Skip the fiddly drag-and-align. Describe the diagram in plain language and get precise, lint-checked Visio output you can keep editing.
Set up once
From install to first figure
Install & connect
Install on Windows 11. A tray app runs the local server and registers it with your Claude and ChatGPT apps automatically; other MCP clients connect with a URL.
Open your document
Open Visio. Vizspect™ attaches to your live session; it never launches a hidden copy or touches anything you didn’t ask it to.
Ask your assistant
Tell your assistant what to draw. Watch the figure build in Visio, then refine by conversation or by hand; you’re always in control.
Ready to draw faster?
Vizspect™ is in limited private use, with a wider release coming soon.
For Windows 11. Requires Microsoft Visio and a supported AI assistant.
