AI image generation without paying anything: what to expect in 2026
Midjourney has become synonymous with AI image generation, but the mandatory subscription model, which in 2026 starts around $10 per month on the basic plan, drives away many people who just want to try the tool or have sporadic use. The good news is that there are free and functional alternatives, some with Portuguese interface, that work well from the curious beginner to the professional who needs quick prototypes at no cost.
This guide brings together the main options available today, explains how each one works in practice and helps you choose the right tool for your case. The short answer: for most everyday uses, a combination of Adobe Firefly (free version) and Microsoft Designer works well, without spending a single cent.
Why Midjourney is still the reference, and where alternatives come close
Midjourney is trained on a huge volume of images and has aesthetic refinement that many competitors are still trying to achieve. The weak point for Brazilian users is precisely the access: there has been no free plan since 2023, payment requires an international card and there is no official Portuguese support.
Free alternatives have improved significantly over the past two years. Tools based on models like Stable Diffusion (an open-source model that any company can adapt and host) and Adobe and Microsoft’s own proprietary models have reached a level where the quality difference, for uses that are not highly specialized, is no longer decisive. Understanding what each tool prioritizes, whether photorealism, illustration, concept art or interface design, is more important than chasing the “most powerful” tool in the abstract.
The best free options in 2026
Adobe Firefly (firefly.adobe.com)
Adobe Firefly is Adobe’s image generator and has a free plan with monthly credits that renew automatically. In 2026, according to Adobe itself, the free plan offers a limited number of monthly generations in standard resolution, sufficient for casual or sporadic professional use.
The most important differentiator for commercial use is that Firefly is trained exclusively with licensed or public domain images, according to the manufacturer. This means you can use the result in professional projects without the legal risk that exists in other generators trained with data of dubious origin. The interface is available in Brazilian Portuguese and works directly in the browser, without installation.
The weakness of the free plan is the watermark on high-resolution exports and the credit limit. If you need volume, the paid plan integrated with Creative Cloud makes more sense.
Microsoft Designer and Bing Image Creator
Microsoft Designer and Bing Image Creator use the same engine underneath: OpenAI’s DALL-E model, integrated with Microsoft services. Access is free for anyone with a Microsoft account and does not require a credit card.
Bing Image Creator is the simplest of the two: you type what you want, in Portuguese itself, and receive four variations. Designer adds layout and editing tools, useful for creating social media posts, presentations and marketing materials. The photorealistic quality is competitive with Midjourney for common scenes, although more elaborate artistic style still shows a difference.
The practical limit is that the system uses “boosts” for fast generations; when they run out, generation becomes slower, but does not stop working. For moderate daily use, this rarely becomes a problem.
Google ImageFX (labs.google)
Google ImageFX is part of Google Labs and uses Google’s own Imagen model. Access is free with a Google account and the interface works in Portuguese. According to Google, Imagen was designed with a focus on security and photorealistic quality, with robust filters for sensitive content.
The strong point here is the natural integration with the Google ecosystem: those who already use Google Workspace have less friction to adopt the tool. The weak point is that it is still treated as an experimental product, so stability and availability may vary. It’s always worth checking the current status directly on Google Labs before relying on the tool for a project.
Stable Diffusion via online platforms (Playground AI, Tensor.art, NightCafe)
Stable Diffusion is an open-source model, which means that anyone or any company can host and provide access. Platforms like Playground AI, Tensor.art and NightCafe offer free daily generations using model variants, often with models specialized in specific styles, such as anime, photorealism or concept art.
The learning curve is steeper. You will encounter terms like LoRA (fine-tuning the model for a specific style, think of it as an advanced “filter” trained separately) and CFG Scale (how strictly the model follows the text you wrote). It’s not necessary to understand everything to get started, but those who want consistent results will need to explore the settings. The interfaces of these platforms are not translated to Portuguese, but prompts work in Portuguese on most of them.
How to write prompts in Portuguese and get good results
Prompt is the text you write to describe the image you want to generate. It’s the equivalent of giving instructions to a designer. Most models accept Portuguese, but some were trained more in English and respond better to technical terms in that language.
A structure that works well in any tool:
- Describe the main subject with detail: “a woman with curly hair, wearing a white coat”
- Add the environment or scenery: “in a modern laboratory, soft lighting”
- Specify the visual style: “photorealistic”, “watercolor illustration”, “sci-fi concept art”
- Include details of quality and composition: “high resolution, medium shot, sharp focus”
- If the tool supports it, use negative prompts (what you don’t want in the image): “no text, no distortion, no watermark”
Avoid long and confusing sentences. Be specific about what matters and eliminate the rest. Tools like ChatGPT can help refine your prompt: describe what you want in natural language and ask it to transform it into a prompt optimized for image generation.

Real limitations you need to know before choosing
None of these tools is perfect. The free ones have generation limits, and when you exceed the quota, either you wait or you pay. Quality in very high resolution usually lags behind paid plans. Human face generation still produces visual errors in complex situations, a problem that affects the entire category.
For use in Brazil, the most practical point is that all these tools work via browser, without need for specific hardware. There is no Anatel homologation issue involved, because this is not a physical device. The only real concern is to check the terms of use before applying generated images to commercial projects: each platform has its own policy on the rights of the generated content.
Those who need high volume, style consistency across projects or integration with professional workflow will find the limits of free versions early on. In these cases, it’s worth evaluating the paid Firefly plan within Creative Cloud or Midjourney itself, weighing the cost against the productivity generated.
Frequently asked questions about free Midjourney alternatives
Can I use images generated for free for commercial purposes?
It depends on the tool and the plan. Adobe Firefly on the free plan allows commercial use according to Adobe, but it is essential to read the updated terms before publishing. Microsoft and Google have specific restrictions in the terms of service that change periodically. Always check the content rights policy generated directly on the tool’s website before using it in a paid project.
Do these tools work well with prompts written in Portuguese?
Yes, with varying quality between them. Adobe Firefly and Microsoft tools have been optimized for multiple languages and understand Portuguese reasonably well. Tools based on Stable Diffusion via independent platforms may have lower performance with Portuguese, especially for very specific technical vocabulary. Mixing keywords in English for style terms still helps improve results on some platforms.
Do I need to install any program to use these tools?
No, all options listed here work directly in the browser. Those who want to use Stable Diffusion locally, without generation limits and with full control, would need a computer with an Nvidia graphics card with at least 8 GB of VRAM, but this is an advanced option and is beyond the scope of free and accessible alternatives for most readers.
Is there a risk of plagiarism or copyright violation when using these tools?
The risk exists in all AI generation, but varies according to the model. Adobe Firefly is the one that offers the most guarantees in this regard, because Adobe claims that the model was trained only with licensed images. The other models were trained with internet data more broadly, which raises legal questions still being debated worldwide. For projects of high commercial impact, consulting with a lawyer specializing in intellectual property is recommended regardless of the tool used.
What to do now
If you want to start today, the most practical sequence is: open Adobe Firefly with your Adobe account (or create a free one), test Microsoft Designer with your Microsoft account and compare the results for your specific type of use. Save credits for projects that really matter and use Bing Image Creator for drafts and tests.
Those interested in technology and everyday productivity, just as they follow launches of devices like the Echo Dot Max, will notice that generative AI tools follow the same pattern: the free product works well for casual use, and the paid version only makes sense when the frequency of use justifies the investment. For now, for most Brazilians, the free version is more than enough.
