# Sketch

> Sketch before you build.

Sketch is the newest part of Propane. Your brainstorm becomes a spec. Your spec becomes a sketch. Your team reacts, aligns, and builds the right thing.

Turn your spec into a sketch your whole team and agents can align around — before you build.

## Why Sketch

The bottleneck was never building. It was always shared understanding. Propane fixes that.

We're launching Sketch because shipping fast without shared understanding just means building the wrong thing faster. It is the next step in Propane's mission to collapse the entire product workflow, from insight to specification to alignment to production, into one connected loop.

Write the spec in Canvas. Generate the sketch. Share with your team or drop it into your coding agent. Everyone builds from the same context.

## What's in Sketch

- **Generated from your spec, not from scratch** — Sketches pull from the Canvas you've already written. Customer data, insights, market context, the why behind the what. No blank canvas. No setup. No re-explaining what you meant.
- **Built for feedback, not approval.** — Lo-fi by design. Nobody asks why it isn't finished. They just tell you if the idea makes sense. The roughness is intentional. It invites reaction instead of reverence.
- **Align your team before you commit.** — Share a Sketch before the design brief, before the sprint, before the meeting. Catch the disagreement before it costs two weeks. Everyone sees the same thing and reacts to the same idea.
- **Iterate with humans and agents.** — Generate multiple versions. Share with a stakeholder, a designer, an engineer. Run it by your coding agent. Unlimited sketches, no design skills needed, no blockers.
- **Hand off to agents with full context.** — Drop a Sketch into Lovable, Cursor, or v0 alongside your full Propane spec. The agent gets the visual and the product reasoning behind it. Less interpretation. Fewer wrong builds. Better product.

## FAQ

### What is Sketch?

A lo-fi visual generator built into Propane. You write the spec, it generates something your team and agents can align around. No drawing, no design skills, no blank canvas.

### Why do I need this?

Because what you wrote is invisible until someone builds the wrong thing. Sketch makes your thinking visible before anyone touches Figma or writes code.

### What is Propane?

An agentic product workspace that collapses the PM stack into one loop — customer insights, spec, alignment, handoff to coding agents. Sketch is one layer of that. If you are jumping between Notion, Dovetail, and ChatGPT today, Propane is what replaces that.

### What is this replacing in my stack?

The step where you either draw a wireframe from scratch in Balsamiq, paste a description into Magic Patterns, or skip the visual entirely and hope your team understood the doc. That step is now instant.

### How is this different from just using Claude or Cursor?

Claude is general. Sketch is specific. It generates a lo-fi visual directly from your Canvas spec, attaches the full product context, and gives you a shareable link — all in one step. You are not prompting from scratch. You are rendering thinking you already did.

### Is this a wireframing tool?

No. Balsamiq and Figma start from a blank canvas. Sketch starts from your spec. Lo-fi by design, so the conversation stays on the idea, not the pixels.

### Will it replace Figma?

No. Sketch is what happens before Figma makes sense. Once the team has aligned on direction, take it to Figma or hand it straight to a coding agent.

### Does it work with Claude Code, Cursor, Lovable, and v0?

Yes. Drop a Sketch into your coding agent alongside the Propane spec. The agent gets the visual and the product reasoning behind it. Better context, fewer wrong builds.

### What about my data? My specs are sensitive.

Your data stays yours. We are SOC 2 Type II certified, everything is encrypted at rest, and credentials are locked down with restricted access.

### We are a team. How does sharing work?

Every Sketch gets a shareable link. Anyone can view it — no Propane account needed. Feedback folds back into the Canvas so the spec stays current.

### Do I need design skills or any setup?

No. Write the spec in Canvas, hit generate. That is it.

### Is Sketch free?

Sketch is in alpha and included in Propane early access. Sign up or book a call to get in.
