How is this different from a daily-prompt website?

Most daily-prompt sites give one word per day. This is a combiner: object + style + constraint, all randomised, all individually lockable. You can iterate to a prompt instead of being handed one.

Is the 31-Day Challenge tied to October?

It's available year-round. In October, the 'Today' button auto-selects the current date. In any other month, the challenge defaults to Day 1 — pick any day you want.

Where is challenge progress stored?

Locally in your browser's localStorage. You can export the progress as a JSON file and re-import it to back it up or move to another device.

Can I add my own styles or constraints?

Not yet. The style and constraint libraries are curated. Reach out via the contact link in the footer with suggestions.

Why are some objects greyed out as I re-roll?

The randomiser excludes the last 30 objects you've seen so consecutive rolls feel fresh. After 30 unique objects, anything is fair game again.

What it does

Three-segment combiner

[Object] + [style] + [constraint]. 400+ objects · 30 hand-curated styles · 25 hand-curated constraints.

Per-segment lock and re-roll

Lock the segments you like. Re-roll only the unlocked segments to refine the prompt without losing what works.

31-Day Drawing Challenge

31 hand-picked objects, one per day, available year-round. Today defaults to the current date in October. Local progress tracking with JSON export and import.

Style library

Watercolour, blind contour, isometric, art nouveau, pixel art, cross-hatch, low-poly, ukiyo-e woodblock, sumi-e ink wash, riso two-tone, silhouette, and more.

Constraint library

In 60 seconds. Without lifting the pen. With your non-dominant hand. Using only triangles. From memory. Upside-down. As if drawn by a child. As a flat icon.

How to use Random Drawing Prompt Generator

2
Lock segments you like
Tap the lock on object, style, or constraint. Locked segments stay; the rest re-roll.

Pen, tablet, sticky note — the prompt is one short sentence you can read and start.
4
Open the 31-Day Challenge
Show the challenge grid for a deterministic prompt per day, with locally-saved progress.

When to use this

Daily art practice

Open the page each morning, lock "in 60 seconds" as the constraint, and re-roll the object until something feels good. One minute later, you have a sketch.

Sketchbook warm-up

Lock the style as "blind contour", press Re-roll three times, and warm up the eye-to-hand connection before serious work.

October challenge

Open the 31-Day Challenge in October. Each day pre-selects an object. Lock it, re-roll style and constraint until the prompt clicks, draw, mark the day complete.
