What to Type for AI

Generate On-Brand Instagram Graphics Without Learning Design

If you're posting 3–5 times a week but dreading the blank Canva canvas every time, you're not alone. Most solo creators skip visual consistency because design tools have a learning curve and stock photos look generic.

AI image generators like Midjourney and Flux can produce custom graphics in seconds—but only if you know how to write the right prompts. A bad prompt gives you the wrong colors, wrong mood, or graphics that don't match your last post.

This page explains how to use templated AI prompts to generate on-brand Instagram graphics every single week, without design skills, without hiring a designer, and without guessing.

Why Generic AI Prompts Fail for Instagram

You can find AI image prompts online, but most are generic: "a woman smiling in a coffee shop" or "minimalist desktop workspace." When you run these through Midjourney, you get random colors, random fonts, and a feed that looks like it came from five different brands. Your Instagram grid tells a story about who you are. Inconsistent visuals break that story. Followers notice. Even if they don't consciously see it, feeds with mismatched colors and styles get fewer saves and shares. Templated prompts solve this by building in your exact brand colors, a consistent visual style, and a repeatable formula. Every image comes out looking like it belongs to you—before you ever touch Canva.

How Fill-in-the-Blank Prompts Save Time

A templated prompt looks like this: "[Subject related to your niche], [action], shot from [angle], minimal style, hex color palette #2D3142 #F4A460 #FFFFFF, professional product photography." You replace the bracketed sections with your week's topic. If you're a solopreneur writing about productivity, you might fill it as: "[person at desk], [writing in journal], [overhead], minimal style, hex color palette #2D3142 #F4A460 #FFFFFF, professional product photography." One paste into Midjourney. One result. No prompt engineering. No experimenting. This cuts your graphics creation from 20 minutes to 2 minutes.

The Brand Anchor Sheet: Your Visual Lock

Before you write a single prompt, you need one phrase that defines your visual style. This is your Style Lock Phrase—something like "moody warm minimalist" or "bold high-contrast luxury." You append this phrase to every prompt. It's a visual anchor. It tells the AI: this is what my brand looks like, keep it consistent. Without it, you drift. Mint green turns into teal. Warm feels turn clinical. Your Brand Anchor Sheet is a one-time setup. You answer 3–4 questions about your aesthetic, and out comes your phrase. Then you copy it into every prompt for the next 12 weeks. Same visual signature, every post.

Platform Dimensions Built Into Every Prompt

Prompts in this system come in four formats: Instagram square (1080×1080), TikTok vertical (1080×1920), carousel hero (1200×628), and Pinterest tall pin (1000×1500). Each prompt includes subtle language that helps the AI output in the right ratio. You don't have to crop or resize or mess with Canva layers. Paste, generate, download. The dimensions are locked. You get a quick reference sheet with export specs for each platform—DPI, file format, safe zones. No guessing whether your text will get cut off on mobile.

What Happens When AI Output Misses the Mark

Even with locked prompts, AI generators sometimes fail: wrong color, over-stylized, text that's garbled, or the brand doesn't match your last 10 posts. The system includes a troubleshooting guide with 6 common failure modes and exact fix language to copy-paste. "Wrong colors" → add "desaturate background 40% and brighten primary swatch by 20%." "Brand drift" → clarify the style lock phrase and remove competing descriptors. You don't debug prompts from scratch. You use tested language tweaks. 90% of problems get solved with a one-line edit.

Finishing in Canva (If You Need To)

Most generated images are post-ready. But sometimes you need to add text, a logo watermark, or adjust a headline. The system includes worked examples showing the exact Canva steps: font pairings, text hierarchy, color overlays that keep the AI image readable. This isn't a design course. It's the minimum viable finishing work. Type, adjust opacity, export. 5 minutes max. You're not learning Canva. You're using it as a tool, not a crutch.

Consistency Checks Before You Post

A pre-post checklist walks through four dimensions: color (does this match your brand palette?), typography (are fonts from your approved pairing list?), composition (does the rule of thirds hold?), and grid cohesion (does this post fit the visual rhythm of your feed?). This takes 30 seconds. It catches drift before it reaches 20 followers. Over 12 weeks, you build a feed that looks intentional, not random.

FAQ

Do I need to know Midjourney or Flux before starting?

No. The prompts work with either tool. You just need an account and $10-20 in credits. The prompts are written to work immediately—no prompt engineering skill required.

What if my brand colors are outside the hex codes you suggest?

The Brand Anchor Sheet walks you through finding your own hex codes. You plug them into the template. The system is customizable to any palette.

Can I use these prompts for TikTok or Pinterest instead of Instagram?

Yes. The system includes dedicated prompt sets for all three platforms. TikTok vertical, Instagram square, and Pinterest tall pins all have their own 12-week rotations.

What if I miss a week?

Pick up where you left off. The prompts are organized by week, not by date. If week 3 didn't happen, you use week 3 next Monday. No scrambling or falling behind.

Do the generated images have copyrights issues?

That depends on your Midjourney or Flux subscription. Both allow commercial use if you have a paid plan. The system doesn't change copyright rules—it just helps you use the tools correctly.

How long does a full workflow take (prompt to posted)?

Ideally 5–10 minutes per graphic: fill in two brackets, paste into Midjourney, wait for generation (1 minute), quick check against consistency list, download, post. Once a week on Sunday takes 30 minutes for five graphics.
