AI Image Editor with Text Prompts
Upload a photo, write what to change — that is the whole workflow. UnitPic is an AI image editor with text prompts: instead of layers, masks and brush tools, you describe the edit in a sentence and the model does the rest. And because one model's idea of "make it look professional" is rarely the same as another's, UnitPic runs your edit on several AI photo editors at once and shows every result side by side.
Every new account starts with free credits — no card required — so you can try this AI photo editor with text prompts free before spending anything.

STEP 1
Upload your photo
Drop in the image you want to edit — a product shot, a portrait, a screenshot, anything. Some models accept up to 14 reference images, so you can include style examples or multiple angles in the same edit.
STEP 2
Write the edit as a prompt
Describe the change in plain words: "keep the person, replace the background with a white studio", "turn this sketch into a watercolor". No layers, no masks — the text prompt is the entire instruction.
STEP 3
Compare models side by side
Pick 2-3 models and they all run the same edit at the same time. Results appear next to each other, so you see in one glance which AI image editor understood your text prompt the way you meant it.
Why edit photos with text prompts
Traditional editors make you do the surgery: select the subject, feather the edge, paint the mask, fix the seams. An AI photo editor with text prompts flips the division of labor — you state the goal ("white studio background, keep the reflections") and the model handles selection, blending and lighting. The skill moves from mousework to writing a clear instruction, which is why prompt-based editing has become the default for product shots, quick retouching and concept iterations. The one thing traditional editors still win is pixel-exact control; for everything else, a sentence is faster.
11 models can edit your photo — compare them all
Every model below accepts reference images, which is what turns a text-to-image generator into an AI image editor. They differ in how many reference images they accept, how faithfully they preserve the original, and what each edit costs. All of them run on one credit balance inside UnitPic.
| Model | Vendor | Ref images | Credits / image | Speed |
|---|---|---|---|---|
| Grok Imagine Image 2.0 | xAI | up to 5 | 10 | ~5s |
| FLUX.2 [flex] | Black Forest Labs | up to 8 | 13 | ~10s |
| FLUX.2 [pro] | Black Forest Labs | up to 8 | 8 | ~10s |
| FLUX.2 [max] | Black Forest Labs | up to 8 | 18 | ~15s |
| Nano Banana | up to 3 | 9 | ~3s | |
| Nano Banana Pro | up to 3 | 36 | ~5s | |
| Nano Banana 2 | up to 3 | 18 | ~4s | |
| Nano Banana 2 Lite | up to 3 | 9 | ~2s | |
| Seedream 5 Pro | ByteDance | up to 10 | 12 | ~8s |
| Seedream 4.5 | ByteDance | up to 14 | 10 | ~7s |
| Seedream 5 Lite | ByteDance | up to 14 | 9 | ~5s |
Credits per edited image, standard quality. Some models add a small per-reference-image charge — the studio always shows the exact total before you run it.
What an edit looks like
Background replacement
“Keep the product exactly as is, replace the background with a light gray studio sweep with soft shadows.”
Clothing and styling
“Keep the pose and the face, change the jacket into a navy wool coat and add a plain white background.”
Style transfer
“Redraw this photo as a flat vector illustration with a limited 4-color palette.”
Multi-reference compositing
“Put the person from image 1 into the scene from image 2, matching the lighting of the scene.”
Four real edit instructions. Notice the pattern that makes an AI image editor with text prompts reliable: state what to keep before what to change. Models follow preservation instructions far more faithfully than bare commands.
Free to try, then pay per edit
UnitPic is credit-based: new accounts get free credits to start (no card), and after that each edited image simply deducts from your balance — from 8 credits on Seedream 5 Lite to 36 on Nano Banana Pro. There is no separate subscription for editing, and the same credits work on all 29 generation models, not just the editing ones. If you are looking for an AI photo editor with a text prompt free tier to evaluate first, the free credits are exactly that.
Three tips for writing edit prompts
1. Lead with what stays. "Keep the person and pose, change the background to a beach" beats "beach background" — the model needs to know what is fixed before it starts changing things.
2. One edit per prompt. Stacking five changes into one sentence degrades all five. Run the background swap first, then feed the result back in for the color grade.
3. Use the comparison. The same edit prompt on Nano Banana 2 and FLUX.2 Pro will follow the instruction differently — one may preserve the face better, the other the lighting. Two credits on a second model is cheaper than a reshoot.
AI image editor FAQ
What is an AI image editor with text prompts?
An AI image editor with text prompts lets you change a photo by describing the change in plain language — no layers, masks or brush tools. You upload the picture, write an instruction like "make the background a beach at sunset", and the model returns the edited image. On UnitPic you can send the same instruction to several models at once and pick the best result.
Is there a free AI photo editor with text prompts?
Yes. UnitPic gives every new account free credits, no card required, which is enough to run real edits with the AI photo editor before paying anything. Editing a photo with text prompts starts at 8 credits per image, and free credits can be spent on any model in the catalog.
How many reference images can I upload?
It depends on the model. Seedream 4.5 and Seedream 5 Lite accept up to 14 reference images, Seedream 5 Pro up to 10, the FLUX.2 family up to 8, Grok Imagine 2 up to 5, and the Nano Banana family up to 3. You can combine a photo to edit with style references in the same request.
What kinds of edits can I make with a text prompt?
Common edits include changing or removing backgrounds, swapping clothing, restyling a photo (oil painting, 3D render, film look), cleaning up product shots, and combining multiple references into one image. Because each model interprets an instruction differently, running the same prompt on 2-3 models is the fastest way to find the interpretation you like.
Do I need to learn layers or masks like in Photoshop?
No. The entire edit is a sentence. If the result is not right, you refine the sentence — the same way you would refine a text-to-image prompt. UnitPic also shows every model's result side by side, so you see immediately which model understood your instruction best.
Which model should I pick for photo editing?
For faithful edits that preserve faces and fine detail, Nano Banana 2 or Nano Banana Pro are the strongest. For up to 14 reference images at once, use Seedream 4.5 or Seedream 5 Lite. For a cheap first pass, Seedream 5 Lite at 9 credits is the most economical editor in the catalog. Compare all 13 editing models in the table above.
