AI Images for Beginners: Make a Xiaohongshu Cover in 10 Minutes

Picture this: you want to post on Xiaohongshu tonight but you have no good cover image; your blog article needs a featured image; or you just want a fresh profile avatar. You can't draw, you don't own Photoshop, and hiring a designer for one picture feels ridiculous. In 2026 you don't need any of that: AI image generation turns a sentence you type into a finished picture in about a minute, and a usable cover takes about ten minutes start to finish. This guide walks you through ChatGPT image generation, Jimeng and Canva, from zero to a real Xiaohongshu cover.

Before you type anything: decide three things

AI images fail mostly because the prompt is vague, not because the AI is bad. Spend two minutes answering three questions first. First, the subject: what exactly is in the picture? A latte, a cat, a girl in a yellow dress? The more concrete, the better. Second, the style: what should it look like — 3D cute, Instagram style, hand-drawn, photo-realistic? Third, the ratio: how tall or wide? Get this wrong and your image will be cropped awkwardly.

• 3:4 portrait — the Xiaohongshu cover standard; taller than it is wide
• 1:1 square — avatars, Instagram feed posts, product cards
• 16:9 wide — article featured images, YouTube thumbnails, blog banners

Copy-paste prompt templates (Chinese works great)

You don't have to invent prompts from scratch. Copy one of these, change the subject, and run it. The formula is: subject + style + lighting + ratio + negative prompt (the things you don't want in the picture).

夏日午后街边咖啡店，一杯冰拿铁放在原木桌上，旁边有一本翻开的杂志和一束干花，阳光透过玻璃窗斜照进来，柔和暖色，ins 风摄影感，画面干净留白多，竖版 3:4。负面：文字、水印、畸形手指、乱入的人脸。

一只圆脸橘猫戴着小草帽坐在草地上，3D 卡通可爱风，马卡龙配色，柔光，正方形 1:1，背景干净纯色。负面：文字、水印、低清晰度、多余肢体。

一个人坐在书桌前用笔记本电脑，桌上有咖啡和小盆栽，手绘水彩风格，明亮清新，横版 16:9，画面右上方留白方便加标题。负面：文字、水印、杂乱背景、过暗。

The negative prompt (负面词) means 'please don't draw these things' — usually text, watermarks, weird hands, blurry output. Add it every time and it removes most ugly images.

The three tools, and which to use when

ChatGPT image generation

You're already in a chat window — just type the prompt and it draws. You can also upload a reference photo and say 'make this into a watercolor illustration'. Free accounts can generate basic images with a limited daily quota; the paid Plus plan unlocks more modes and higher limits. Exact quotas change often, so check the official site before paying anything.

Jimeng (即梦)

Jimeng is a Chinese-made tool, reads Chinese prompts naturally, and gives daily free credits that are enough for a beginner to practice all day. The workflow is simple: paste your prompt, pick the ratio (3:4 / 1:1 / 16:9), hit generate, then download the result to your phone or computer. Credits reset daily; the exact free quota is posted on their official site, so check it there.

Canva

Canva is not mainly an AI generator — it's a template library plus a design editor. The smart combo: generate the artwork in ChatGPT or Jimeng, bring it into Canva, pick a cover template, and drag on the title text. This is how real Xiaohongshu covers get their neat, professional-looking typography, because AI is terrible at writing Chinese characters (more on that below).

Full walkthrough: a 'summer coffee shop' Xiaohongshu cover

1. Step 1 — pick the tool: open Jimeng on your phone (free credits, Chinese-prompt friendly)
2. Step 2 — paste the coffee template above, set ratio to 3:4, hit generate; if you don't like it, hit generate again — each click is a new take
3. Step 3 — download your favourite image to the phone
4. Step 4 — open Canva, search 'Xiaohongshu cover' templates, pick one in the same warm style
5. Step 5 — replace the template's background with your generated image, then add the title text, e.g. 'My Favourite Coffee Shop This Summer'
6. Step 6 — export as PNG and post

Common mistakes beginners make

• Asking the AI to write text on the image — Chinese characters come out garbled. Solution: generate a clean background, add all text in Canva
• Picking the wrong ratio — a 16:9 image stretched into a 3:4 cover looks cramped. Decide the ratio before generating
• Not knowing style words — start from a short list: 3D cute (3D 可爱风), Instagram style (ins 风), hand-drawn (手绘风), watercolor (水彩风), photo-realistic (摄影写实), minimalist flat (极简扁平)
• Ignoring safe margins — keep the subject centered, because the platform may crop the edges when displaying. Never put the title or a key detail right at the edge

That's the whole skill: decide subject, style and ratio, copy a prompt, generate two or three times, add the text in Canva. You now have everything a designer would charge money for — except it took ten minutes and cost nothing. Tomorrow, swap the subject in the template and you've made another cover.
