A whiteboard for the systems you explain out loud

Say the system.
Shape it by hand.

Describe your architecture the way you'd explain it to a teammate. Voicegraph draws it, lets you drag every box into place, reviews it for weak spots and writes the README section for you.

Start with your voice Try the sample

Built with Wispr Flow · Hold Fn, speak, let go.

Example workflow
“Shoppers hit a Next.js storefront, it calls the orders API, and the API writes to Postgres. Put a Redis cache in front of the database.”

One sentence. A diagram you can drag.

Less dragging.
More designing.

For the moment you can explain your system in thirty seconds but drawing it would take thirty minutes.

A flow that follows your thinking

Speak. Shape.
Then ship.

  1. 01

    Say what you're building.

    Hold Fn with Wispr Flow and talk. “Add a queue between the API and the email worker.” Self-corrections like “no wait, Kafka” are understood.

  2. 02

    Shape it by hand.

    Drag boxes, draw connections, double-click to rename. Select a box and say “make this red” or “connect this to Stripe”. Your layout stays put.

  3. 03

    Review, then ship it.

    Ask for an architecture review, get a README section written from the diagram, and export PNG, SVG or a Mermaid block GitHub renders natively.

Voice-first editing

Dictation runs by itself the moment it lands. “Undo”, “tidy up”, “download PNG” work instantly.

Drag-and-drop canvas

Smooth panning, zoom, multi-select, minimap and groups that follow their boxes.

Architecture review

Flags single points of failure, missing caches and risky sync calls, pinned to the boxes involved.

README in one click

Overview, components and data flow, written from what you drew, with the diagram as Mermaid.
