Which AI Image Tool Should You Use? A Plain Guide for Beginners

If you just want a good picture for a birthday post, a festival greeting, or a couple portrait, the tool you pick matters less than you'd think — but a few real differences will save you frustration. The two easiest places to start are ChatGPT (which generates images through a model called DALL-E, or GPT's newer built-in image generator) and Google Gemini. Both work the same way you already chat with a person: you type or paste a description in plain English, hit send, and a picture appears in the reply. There's nothing to install, no settings to learn, and both have free tiers. For someone making their first AI image, this is where to begin.

ChatGPT is the most forgiving for beginners because it "talks back." If your first result isn't quite right, you can just reply "make her saree red and the background a temple at sunset" and it edits from there, no need to rewrite everything. It's strong at following long, detailed instructions and at putting readable text into an image — useful for a "Happy Birthday Priya" status graphic or a festival greeting with a name on it. Google Gemini is its closest cousin and is excellent when you want to start from a photo you already have: you can upload a picture of yourself or a couple and ask it to restyle the scene, change the outfit, or place you against a new backdrop. Gemini also tends to render faces and Indian skin tones more naturally than some rivals, which is why many people prefer it for personal portraits.

Midjourney sits at the other end. It produces the most cinematic, magazine-quality images of the lot — the kind of dramatic lighting and texture you see on fan posters and wallpapers. But it is genuinely harder to get going. For a long time it ran only inside Discord (a chat app), where you type "/imagine" followed by your prompt, and it has a paid subscription with no real free tier. It also doesn't take instructions as literally; it goes for "beautiful" over "exactly what you asked." If you want a stunning solo portrait or a poster-style edit and don't mind a learning curve, it's worth it. If you just want a quick, accurate greeting, start elsewhere. Beyond these three, you'll see names like Leonardo, Ideogram (great for clean text in images), Bing Image Creator (free, powered by the same DALL-E), and Adobe Firefly (handy if you already use Photoshop or Canva).

Running a copied prompt is simpler than it sounds. Open ChatGPT or Gemini, find the message box at the bottom, paste the prompt text in (long-press and tap Paste on a phone, or Ctrl+V on a computer), and press send. Wait a few seconds and the image appears. If the result is close but not perfect, don't start over — just reply with one change at a time: "make it brighter," "remove the extra hand," "9:16 vertical for a status." Most copied prompts already include the style, lighting, and mood, so your only real job is to personalize them.

That personalizing step is where placeholders come in. A well-written prompt often has fill-in-the-blank spots, usually shown in brackets like [NAME], [HER OUTFIT], or [OCCASION]. To use it, you simply replace the bracket and the words inside it with your own detail before you send — turn "a portrait of [NAME] wearing [OUTFIT]" into "a portrait of Arjun wearing a navy kurta." Delete the brackets too. For prompts that work from a photo, the swap is even easier: upload your own picture in the same message where you paste the prompt, and say "use the person in this photo." The tool keeps the face and applies the described scene around it.

A couple of honest pitfalls to expect. AI still struggles with hands, fine jewellery, and text it wasn't explicitly told to write — so check fingers and spellings before you post, and re-roll if something looks off. Faces of a specific real person are hard to reproduce exactly from a description alone; if you need to look like you, use the upload-a-photo route in Gemini or ChatGPT rather than describing yourself. And free tiers have daily limits, so save the images you like as you go.

The shortcut through all of this is to not write prompts from scratch at all. You can browse the ready-made prompts here on Prompt Deck — for couple portraits, birthday and festival greetings, collages, status graphics and more — copy the one you like, paste it into ChatGPT or Gemini, swap the name or photo, and you're done. Pick the easy tool, start with a proven prompt, and change only what's yours.
