How TrendShift works

TrendShift turns one idea into dozens of ready-to-use AI image prompts for t-shirts and print-on-demand. It doesn't make images itself — you paste the prompts into Midjourney, Flow, Ideogram, GPT Image, etc.

The 3-step flow

1Say what you want

Type a quote ("Reel Cool Dad") or a subject ("a frog"), or upload a design.

2Pick styles

Click the looks you like in the Style library — trending Etsy/Amazon/Pinterest styles, internet aesthetics, folk art, crafts, art history, text layouts, charts, magazine covers and 22 holidays.

3Generate

You get one prompt for every input × style. Copy all, or export CSV / TXT for bulk image making.

Example: 2 quotes × 10 styles = 20 prompts, each a different design.

The tabs

Style library — 1,900+ styles in 43 sections (trending sources, internet aesthetics, folk art, crafts, packaging, tattoo, games, art history, 22 holidays and more). 🔥 badges show where and when a style was seen selling. Click a card to select it, ★ to save it, hover to zoom, See: Amazon / Etsy / Pinterest to check real examples.
Text templates — 100 text-only shirt layouts and fill-in-the-blank phrase formulas.
Fonts — 100 trending POD fonts. "Free" ones are OK to sell with. Click Use to put a font's look into your prompts.
Output — your prompts. History keeps your last 30 batches.

The settings (left panel)

Design / Quote — picture ideas or text shirts. Design mode can also add text, "No text", and extra details.
Background — transparent, solid, or made for dark / light shirts.
Ink colors — let the style decide, limit the number of colors, or pick exact colors.
Size — Merch 4500×5400, Etsy 4:5, square, sticker, poster, mug wrap and more.
AI target — writes the prompt the way your image tool understands it.

Good to know

Prompt detail (Settings drawer, under AI target) — Detailed writes full prompts: solid background for easy removal (never a mockup), the style technique, composition, exact ink colours, text rules and an avoid list. Short gives the old compact prompts.
Personalize — type {name}, {year} or {city} in a quote or subject and fill them in under Extra details. Trend palettes live under Ink colors → Specific.
Always check phrases and art styles for trademarks / copyright before uploading. Art styles marked ⚠ need extra care.
