How it works

Every prompt is assembled from independent parts so the combinations are practically endless. No account, no server — everything runs in your browser.

1
Choose a genre (UI, branding, typography…) or leave it on "Any" for a surprise.
2
Set a difficulty — Easy for daily warm-ups, Hard when you want a real stretch goal.
3
Toggle constraint types — color limits, device targets, mood, time cap, and more are mixed in.
4
Hit Generate. Copy the text or download a PNG card to keep in your sketchbook.

Example output: "Design a landing page for a yoga studio using only 2 colors, no photography, targeting mobile — 30-minute time limit."

Frequently asked questions

What is a design prompt generator and why use one?
A design prompt generator gives you a short creative brief — a subject, constraints, and sometimes a time limit — so you have something concrete to practice on instead of staring at a blank canvas. Regular practice with varied prompts builds speed, expands your style vocabulary, and mimics real client briefs. It is used by design students, working professionals warming up before client work, and bootcamp attendees who need structured daily challenges.
What kinds of constraints does this generator include?
Constraints are grouped into seven types: Color palette (e.g. monochrome, limited to 2 colors, complementary only), Device / format (mobile-first, desktop, poster, billboard), Visual style (flat, isometric, retro, brutalist, glassmorphism), Client type (startup, non-profit, luxury brand, local restaurant), Time limit (15 min, 30 min, 1 hour), Mood / emotion (energetic, calm, playful, serious), and Creative restriction (no gradients, no icons, type-only, single typeface). You can toggle any of these off to narrow the challenge.
Can I use these prompts for portfolio pieces or client pitches?
Absolutely. The prompts are deliberately open-ended — there is no single "right answer," which makes them ideal for speculative portfolio work (often called "spec work"). Add your own creative interpretation, and the resulting piece is entirely your own original work. Many designers include prompt-based practice pieces in student portfolios or design challenges like 100 Day Project entries.
Does this tool save my history or send data to a server?
No data ever leaves your browser. Your last 20 generated prompts are saved in your browser's localStorage so you can revisit them after closing the tab — but nothing is sent to any server. Clearing browser data or clicking "Clear all" removes the history instantly.
How do I use the PNG export?
Click "Save as PNG" after generating a prompt. The tool renders the card to an HTML5 Canvas element and triggers a download of a 900×480 px PNG file. You can add it to Notion, a design journal, a Slack message, or print it and pin it at your desk. The PNG is generated client-side using the Canvas API — no upload required.
I got a prompt that does not match my selected genre — why?
If "Any genre" is selected the generator picks randomly across all genres. If you selected a specific genre and the task still feels off, try generating again — the task pool is large and some tasks are intentionally cross-discipline (e.g. a typography task that also suits branding). Constraints are always generated fresh so two prompts with the same task will still have different constraint sets.
