Text to image AI tools are cheap to start and hard to compare, because each vendor prices a pool of credits or images in its own way. Pixlr leads the AI image category with 100 out of 100, and Z-Image has the highest cost-per-image score: $0.97 per 100 images on Pro (3,000 per month, billed monthly).
How text to image AI pricing works
A prompt-to-image generator is not priced like a scheduler or an editor. You rarely pay per seat. You pay for a monthly pool of credits or images, and what one image costs in that pool depends on the model, the size and whether you re-run a prompt. That is why a low monthly price tells you little until you know what the pool holds.
So read the table with two questions: what does it cost to start, and what does the pool look like one step up. The sections below pair each tool's entry price with its stated monthly allowance wherever the vendor publishes one, and say plainly when it does not.
How we picked
Every tool in the AI image category is scored with the same criteria. For text to image, the ones that matter most are the entry price, whether a free plan exists, how openly the vendor publishes its plans and how many of the tracked image features are verified. Read the methodology for the formulas and what happens when data is missing.
Every one of the 91 AI image generators we looked at is scored by the same 7 criteria (scorecard version 1), each from the vendor's own pricing page, docs or changelog. 62 had enough verified data to be ranked. A criterion without verified data is left out and the remaining weights are re-normalised; under 60% of the weight covered means the tool is not ranked.
| Criterion | Weight | Type | What we measure and how |
|---|---|---|---|
| Entry price | 25% | Core | Price per month of the cheapest paid plan, against the prices of other AI image generators on the same billing basis (monthly-billed prices against monthly, annual-billed against annual).Formula: Log scale. Billed monthly: $6.99/month or less = 100, $29 or more = 0. Only billed annually: $5/month or less = 100, $20.83 or more = 0. Only free plans = 100. Usage-priced and one-time plans are not scored. |
| Free plan or trial | 15% | Core | Whether you can use the tool before paying: a free plan, or failing that a free trial, as shown on the vendor's pricing page.Formula: Free plan = 100. No free plan but a free trial = 60. The pricing page lists plans but shows neither = 0. No plans read = not scored. |
| Pricing transparency | 10% | Core | How much of the pricing is public: the share of plans with a published price ("contact sales" counts against), and whether there are at least 3 published tiers.Formula: 80 x (plans with a public price / plans listed) + 20 x (public plans, up to 3) / 3. No plans read = not scored. |
| Verified features | 15% | Core | How many of the 10 features we track for this category the vendor's own pages verifiably show (analytics, team access, templates, ai assistant, text to image, image to image / reference images, upscaling, inpainting or object editing, commercial use on paid plans, private generations). This counts verified features only: a tool that documents less scores lower here, and only here.Formula: Linear: verified features / 5 (half the tracked list) x 100, capped at 100. No tracked feature verified = not scored. |
| API, integrations and export | 10% | Core | Whether a public API exists, how many integrations the vendor states, and whether the vendor documents a way to export your data.Formula: Average of the parts with data: public API yes = 100, no = 0; integrations on a log scale (100 or more = 100); a documented data export = 100. None verified = not scored. |
| Cost per 100 images | 15% | Category | Price per 100 images on the cheapest paid plan that states a monthly allowance limit (monthly price / allowance).Formula: Log scale: $1 per 100 images or less = 100, $20 or more = 0. Unlimited or unstated allowances = not scored. |
| Cost per user (team of 3) | 10% | Category | Monthly price per user for a team of 3, on the cheapest paid plan that is priced per seat or states room for at least 3 users.Formula: Log scale: $4 per user or less = 100, $79 or more = 0. Plans that do not state a user limit are not used. No such plan = not scored. |
The ranking
The table covers the whole AI image category, so it includes editors and upscalers as well as generators. A high rank means a low entry price, a free plan and openly published plans, not better pictures. The sections that follow only cover tools whose text to image feature is verified in the catalogue. The full list is on the AI image category page, and you can sort it on the best AI image tools page.

Each value links the vendor page it was read from (hover for the check date). Coverage is the share of the scorecard's weight with verified data, and "N of M criteria" how many criteria the score is based on; a tool is ranked at 60% or more.
Score is 0 to 100 on the category scorecard; coverage is the share of scorecard weight with verified data. Prices are list prices in US dollars from each vendor's pricing page; the Checked column is the newest date any fact of that tool was verified. 29 listed without a score because under 60% of the weight has verified data. How the score works: methodology.

Krea pairs a free plan with a large paid credit pool, so it suits someone who wants to explore several models before committing. Its first paid plan, Basic, costs $9 per month and lists 5000 credits per month. The price drops to $5 per month, billed annually if you pay yearly.
The step up to $35 per month lists 20000 credits per month. The catalogue does not say how many images a credit buys on each model, so work that out on the free plan before you pay for a higher one.
- Free plan: Yes, plan price Free.
- Commercial use on paid plans: Yes.
- Image to image and inpainting: Yes and Yes.
- Text to video from the same account: Yes.

Clipdrop is a toolbox of single-purpose image tools with a text to image generator alongside them, which makes it a fit for quick jobs such as removing a background after you generate. The catalogue lists one plan, Free, and no paid price, so it cannot tell you what you would pay to go beyond the free limits.
That gap matters. If you expect to generate images every week for a team, you will need to read the vendor's own plan page before you decide, because this comparison has no paid price to rank it on.
- Text to image: Yes; inpainting: Yes; upscaling: Yes.
- Commercial use on paid plans: Yes.
- Background remover: Yes; API: Yes.

Pixlr is first and foremost a browser photo editor with AI generation inside it, so it suits people who already crop, retouch and add text to their images and want a generator in the same place. Its entry price is $2.49 per month on the Plus plan, with 80 credits per month, which is a small pool next to the 5000 on the first Krea plan, although credits are not comparable across tools.
The $9.99 per month plan lists 1000 credits per month. That jump is large, so if you generate often, price the second plan rather than the first.

Geneso.ai publishes a low-priced ladder of credit plans. Its Starter plan is $3.19 per month with 4500 credits per month, and the $11.99 per month plan lists 20000 credits per month. It also sells usage-based packs, for example $6.99 per month (usage-based).
It suits someone who wants volume at a low monthly price and is willing to learn the platform. It is a weaker fit if you need editing features, because the catalogue verifies text to image (Yes) and templates but no inpainting or upscaling for it.

Z-Image states its plan limits in images rather than credits, which makes the cost easy to read. It has the highest score on cost per 100 images: Z-Image at $0.97 per 100 images on Pro (3,000 per month, billed monthly). The free plan lists 10 images per month, the Starter plan is $9.90 per month for 600 images per month and Pro is $29 per month for 3000 images per month.
The trade-off is breadth. It does text to image and little else in the catalogue, so you would pair it with an editor.

Photo Studio has no free plan, so it only makes sense if you already know you will pay. Its Starter plan is $10 per month with 375 credits per month, and the next plan, at $20 per month, lists 750. What it adds is a verified feature set aimed at finished photos: upscaling, enhancement and private generations.
- Free plan: No; free trial: No free trial.
- Private generations: Yes; upscaling: Yes.
- Commercial use on paid plans: Yes.

Who should not pick it
Each tool above fails some readers. Check the one that describes you:
- If you cannot spend anything yet, skip Photo Studio: its free plan is listed as No and its trial as No free trial.
- If you need a price for a team before you start, skip Clipdrop: the catalogue has no paid price for it, only a Free plan.
- If you need to start from a reference picture, skip Z-Image: image to image is listed as No.
- If you want to compare plans by image count rather than credits, skip Geneso.ai and Krea: they list only credits, such as 5000 per month on Basic.
- If your main need is video, an image-first tool is the wrong start: Krea lists text to video as Yes, but video tools have their own scorecard in the AI video generators for social media guide.
What we did not test
We did not use any of these tools. Everything above is read from vendor pages and scored by code, so it shows what a vendor publishes and what it costs. It says nothing about how sharp the images are, how well a model follows a prompt, how fast it renders, how often a generation fails or how good support is. Those are the things that decide whether a credit is well spent, so try the free plan with your own prompts first. For the full list of what we leave out, see what we do not test.
– = not published by the vendor, or not verified yet.
Frequently asked questions
Can I turn text into images for free?
Yes, on some tools. Krea lists a free plan (Yes) and Z-Image lists a free plan with 10 images per month. Pricing was read from each vendor's pricing page on Oct 14, 2026, so check the page itself before you rely on a limit.
Is a credit the same thing on every text to image tool?
No. Krea lists 5000 credits per month on its Basic plan at $9 per month, while Photo Studio lists 375 credits per month at $10 per month. Each vendor decides what a credit buys, so credit counts only compare inside one tool.
Can I use AI-generated images commercially?
The catalogue tracks whether commercial use is allowed on paid plans. It reads Yes for Krea and Yes for Photo Studio. A yes in the catalogue is not legal advice, so read the vendor's terms before you publish or sell what you generate.
Which text to image tools offer an API?
Clipdrop shows an API as Yes and Z-Image shows Yes on their vendor pages. If you want to generate images from your own code, confirm the API terms and pricing separately, because the catalogue records only that one exists.
Which of the AI image generators ranks first on SaaSHunter?
Pixlr has the highest score, 100 out of 100, among the 62 AI image generators with enough verified data to be ranked. Its facts were last checked Oct 14, 2026. Scores are computed from the published scorecard and change when the underlying facts change.
Which AI image generators have a free plan?
26 of the 62 ranked AI image generators list a free plan: Pixlr, Photofy, Recraft, Clipdrop, Krea, Geneso.ai, nodetool, Z-Image Edit, mlx-serve, Vidnoz, Pika, waifu2x.online, Z-Image, Orelon, VistaCreate, LoraAI, Awesome-GPT4o-Image-Prompts, awesome-gpt-image-2-5-prompts, Let's Enhance, Verbatik AI, Kairval, Nanoart, Remix Mart, Snapitect AI, KreatorFlow AI, Weezard.

What is the lowest starting price among AI image generators?
Among the ranked AI image generators, Pixlr has the lowest paid starting price at $2.49 per month. Tools charge per seat, per connected account or per workspace, so the units differ and the lowest sticker price is not always the lowest bill for your setup.
How are the AI image generators scored?
Each tool is scored from 0 to 100 on 7 weighted criteria taken from the same scorecard for every tool: entry price, free plan or trial, pricing transparency, verified features, api, integrations and export, cost per 100 images, cost per user (team of 3). Criteria without verified data are left out and the weights re-normalised; a tool with under 60% of the weight covered is listed as not ranked.
