NanoBanana vs ChatGPT vs Midjourney for Small Business

Most small business owners think AI image generation requires design skill or "prompt engineering." It doesn't. This week Kai and Tim break down the three tools actually worth using right now — Google's NanoBanana (free inside Gemini), ChatGPT's GPT Image 2 (the tool formerly known as Sora), and Midjourney's new v8.1 model — plus the five-part prompt formula (subject, action, setting, composition, style) that gets you a usable image on the first try instead of the twentieth. They also cover what you actually own when you generate an AI image, why you might not be able to copyright it, and how invisible watermarks like SynthID work.

How to access NanoBanana for free inside Gemini, including daily image limits and what the $19.99/month Pro tier removes. Why the same prompt doesn't work across tools — ChatGPT and NanoBanana want conversational prose, Midjourney wants structured, bullet-style parameters. The five-part prompt formula — subject, action, setting, composition, style (lighting, camera detail, color mood) — for prompts that work on the first try. Why you can just ask AI to write the prompt for you, instead of memorizing the formula yourself. Two small habits that improve results: put exact text in quotes, and list your parameters in order of importance. What commercial rights you actually have on AI-generated images — and the simple trick that restores copyright protection. How invisible watermarks (Google's SynthID, OpenAI's C2PA credentials) mark AI-generated images even when you can't see them. Tools Mentioned NanoBanana / NanoBanana 2 / NanoBanana 2 Lite — Google's image generation model, free inside the Gemini app (gemini.google.com). 20 free images/day with a visible watermark; Pro is $19.99/mo for 100 images/day, no watermark. ChatGPT (GPT Image 2) — OpenAI's image generation, built into ChatGPT (chatgpt.com). Formerly a standalone app called Sora, shut down and folded into ChatGPT; still the strongest at rendering text correctly. Midjourney (v8.1) — Image generation known for the most visually striking output (midjourney.com). No longer requires Discord to use. Note: paid plans don't include commercial rights for companies over $1M in revenue. Claude (Fable 5) — Used in this episode to translate a rough brief into a properly structured NanoBanana prompt (claude.ai).
