Sketch your idea.Erase it tomorrow.
Describe a screen, a flow, or a feeling. Delible will rough it out — hand-drawn, low-stakes, ready to throw away.
Fidelityisafunctionofconfidence
When you're still figuring it out, your prototype should look like it. Hand-drawn, erasable components powered by wired-elements + rough.js.
The brief writes itself — in the margins.
While you sketch, Delible quietly builds the context: every decision, every rationale, every constraint — captured in the background so it travels forward instead of getting lost.

## Warehouse Picker Dashboard
Goal — cut stuck-aisle time by 40%
Constraint — gloved fingers, 5" screen
- Tap-and-hold over swipe
Reviewers confused by direction
- Full-width "stuck" button
Ops manager couldn't find it
- High-contrast only, no gradients

Look as done as you actually are
A thought, not a decision
Every line is provisional. That's not a limitation — it's the whole point. When it looks erasable, people treat it that way.
Sketchy by constraint
Show it rough and people respond to the idea. Show it polished and they respond to the pixels. The fidelity you choose shapes the conversation you get.
Speed is the constraint
There's no way to over-polish. No way to lose a day to alignment. You sketch fast, capture open questions as you go, and hand off the full context brief before the idea loses momentum.
Unlovable by design
Other tools make things look production-ready. Delible makes things look exactly as finished as they are. The roughness is the message.
From the field notes.
Three people who stopped arguing about gradients and started shipping ideas.
"Half my review meetings used to be about button colors. Now they're about the actual product. Delible is the first tool I've used that gets out of the way of thinking."
"We shipped four prototypes in the time it used to take to argue about one. The handoff brief alone paid for it."
"It looks like garbage. On purpose. Stakeholders finally read the flow instead of the gradient."
