Use artificial intelligence for free: The 10 best tools in 2025

When it comes to artificial intelligence (AI) today, most people immediately think of ChatGPT, Gemini, or similar applications. However, these so-called large language models (LLMs) are only the tip of the iceberg. Hidden beneath the surface is an enormous array of tools that can bring AI into our everyday (working) lives in a variety of ways: From text correction and search engine support to image optimization and even comprehensive AI automation for workflows, a lot will be possible in 2025. The question many people ask themselves is: Can you use artificial intelligence for free? Yes, you can! In fact, there are a lot of systems that are available for free and still offer you massive advantages.

Artificial intelligence is no longer just a buzzword used in the boardrooms of large corporations or agencies. It is increasingly becoming the (invisible) driving force in almost every industry and, for many, an indispensable part of everyday life. While AI was still a nice-to-have or even a luxury a few years ago, today it has long been a decisive factor in determining who will be at the forefront (in the long term). Small and medium-sized enterprises (SMEs) should also take advantage of the opportunities offered by automation and the far-reaching analytical capabilities of these technologies. So, let's take a look at the best free AI tools of 2025 that make this possible!

‍

1. ChatGPT – versatile AI assistant

‍

ChatGPT started the public AI wave in 2022. Today, almost everyone in Germany is familiar with the tool from the US software company OpenAI. According to current figures from Bitkom published by Statista in the summer of 2025, most people (25 percent) who use artificial intelligence in their everyday lives do so via ChatGPT. At the touch of a button, the assistant can provide structured information, explain complex issues in an understandable way, or perform reliable data analyses.

The system is very simple: you ask a question or specify a task, and the AI generates suitable results within seconds. You can use this principle in customer service, for example, to pre-formulate various standard responses that your team can then use as appropriate. In principle, it is also possible to use ChatGPT to create extensive blog posts, website texts, or social media content. However, you should be careful with such creative and more complex tasks, as the free version in particular makes more frequent mistakes and spits out comparatively static formulations. ChatGPT is also often used for SEO tips.

In addition, there are image and graphics functions that may open up undreamt-of design possibilities for you—without the need for a media designer. In the chat, you can create impressive infographics or photorealistic images simply by entering text. Using models such as "Sora" (only available for free in selected test phases), ChatGPT can even generate short video clips from text descriptions. OpenAI's bot now has several competitors with very similar capabilities. For a more detailed comparison, we recommend our ultimate AI test: ChatGPT vs. Gemini vs.Perplexity vs. Copilot vs. Claude.

In their private lives, many people use ChatGPT for recipe ideas, simple research, or quick summaries of learning content.

Use artificial intelligence for free with ChatGPT:

• Write texts faster: emails, posts, product descriptions, explanations (but be careful: you'll need to proofread these)

• Research and learning: summarize content, have terms explained in an easy-to-understand way

• Improve customer service: create templates, get suggested responses, provide structured information

2. DeepL and DeepL Write – precise translations and powerful text optimization

If you have international customers or work with foreign-language documents a lot, there's no way around DeepL. The tool has been impressing users for years with its very natural translations and is clearly one of the top solutions in its field. A particular feature is that it automatically recognizes the language – you just have to insert your source text and you'll immediately receive the appropriate output.

Compared to traditional online translators, DeepL often sounds much more natural and understandable. Although the results are not always completely error-free and the free tool has a limited word count, this can be quickly remedied with minimal adjustments and by splitting up the source texts. SMEs can quickly convert product pages, emails, and customer documents for other markets or simply make them understandable for everyone.

In addition, DeepL Write offers a free way to improve texts. The tool analyzes wording, corrects errors, and suggests stylistic improvements. The selection of different styles such as "simple," "business," "academic," etc., is practical. This allows you to efficiently prepare your texts for different situations.

You can also use DeepL and DeepL Write for personal purposes, such as translating travel documents or revising important letters, applications, etc.

Use artificial intelligence for free with DeepL:

• Professional translations for international clients

• Text revision for clear, error-free content

• Easy to get started thanks to an intuitive interface

3. Neuroflash – German all-in-one suite for texts, images, and SEO

Neuroflash focuses in particular on content generation – tailored to the German market and German-speaking users. The tool itself comes from Germany and combines text generation, image production, and SEO analysis in one suite. This makes the platform ideal for marketing teams, freelancers, or small businesses that want to publish content on a regular basis.

Neuroflash creates entire website texts based on short bullet points or helps to develop drafts. The AI can save valuable time, especially when it comes to product descriptions, blog articles, or advertisements. In addition, images can be generated, which is useful if you need visuals for presentations or social media posts quickly, or if you want to perform SEO analyses. In many cases, the free plan is sufficient to test the most important tools. As with ChatGPT, however, it is important to exercise caution, as the AI does not run at full capacity in free mode.

The tool can also be used privately, for example, for photo editing, invitations, or short greeting texts, but the focus here is clearly on business.

Use artificial intelligence for free with Neuroflash:

• Multiple AI functions in one tool: text, images, SEO

• Ideal formarketing: quick drafts, clear structuring, SEO tips

• German provider: focus on data protection and clear UI for German-speaking users

4. Jotform – AI assistants for forms and small automations

With this AI tool, you can take your first steps toward automation without any programming knowledge. It allows you to create AI assistants that perform tasks based on prompts – such as analyzing support requests or pre-formulating appropriate messages. This allows you to streamline workflows without having to develop your own software.

‍

Its ease of use in particular: you select an existing AI assistant or create your own by formulating a few clear specifications. Jotform integrates into existing forms and workflows, which helps small teams in particular to complete recurring tasks more quickly. This is useful, for example, for customer service automation, data collection for marketing automation, or even for internal coordination. Jotform is less commonly used in private settings.

Use artificial intelligence for free with Jotform:

• Automate forms: analyze responses, summarize information

• Generate texts: automatic messages and follow-ups

• Quick start: easy to use without programming knowledge

5. Perplexity – AI search engine with verified answers

Perplexity has quickly become one of the most thorough AI search engines. Unlike traditional services, you don't get a long list of links, but compact and comprehensible answers – including verified sources. This makes your work easier when you need reliable facts quickly or are researching complex topics.

This can be particularly valuable for SMEs: instead of having to gather information from numerous sources, you receive well-founded summaries that can be used directly. Whether market analyses, technical terms, or technical details – Perplexity delivers precise content and often suggests useful follow-up questions. This allows you to quickly create well-structured knowledge modules that you can use for presentations, reports, or as a basis for decision-making, for example.

In a private setting, Perplexity is ideal for researching health topics, travel planning, or learning questions.

Use artificial intelligence for free with Perplexity:

• Fast research: verified facts, sources, and further references

• Complex topics explained in an understandable way: ideal for supporting important decisions in everyday business

• Time savings: less searching, clearer, reliable results

6. Manus AI – autonomous multi-agent for complex tasks

This is undoubtedly one of the most advanced AI systems you can try for free in 2025. Unlike typical chatbots or AI assistants such as ChatGPT, Manus not only works on demand but also automatically breaks down tasks into meaningful steps. The platform uses a multi-agent system that combines different models and thus independently plans and executes research, data analysis, or technical tasks.

This is particularly exciting for companies because Manus maps workflows, creates reports, and even generates code. Processes such as market analyses, content briefings, and small software components can be generated almost entirely automatically. At the same time, Manus is intelligent enough to learn from past tasks and thus deliver ever better results.

Use artificial intelligence for free with Manus AI:

• Automate complex tasks: analysis, planning, and execution through multi-agents

• Structure data and content: generate reports, summaries, and small programs

• Increase efficiency in everyday work: fewer manual steps, intelligent, proactive task assignment

7. n8n – flexible open-source automation for SMEs

n8n("n-eight-n") is a pretty powerful open-source automation tool. Similar to Jotform, it gives SMEs a good opportunity to take their first steps in automation without having to invest in expensive systems right away. However, n8n is much more versatile than Jotform. The graphical interface makes it easy to combine workflows from triggers and actions – for example, when new form entries are to be automatically transferred to a table, a special CRM for law firms, B2B e-commerce, NGOs, etc., or an email template.

A significant advantage is the ability to host n8n yourself. This gives you full control over your data and ensures compliance with the GDPR. The platform can also be expanded flexibly: over 400 integrations and the option to code yourself allow you to create customized workflows that can be tailored precisely to your processes.

Use artificial intelligence for free with n8n:

• Graphical UI: Link tools and data sources without code

• Self-hosting possible: full control and maximum data protection

• Custom workflows: flexibly adaptable for business processes

8. Mokker – fast product images via AI

Mokker is ideal for SMEs that sell physical goods and want to create or vary professional-looking product photos for them without much effort. Once again, it's very easy to use: you upload an original photo, and the AI suggests a wide range of versions. For example, it's possible to place items in different environments without having to organize a real photoshoot.

This offers clear advantages for small shops, start-ups, and local retailers: new designs can be created in just a few minutes and free of charge, saving time and a lot of money. The tool is also ideal for marketing materials and social media posts.

Use artificial intelligence for free with Mokker:

• Create product photos: quickly generate high-quality image versions from uploads

9. Upscayl – Enlarge images without loss of quality

Upscayl solves a common problem: images that are too small or blurry. The AI enlarges image files while improving their quality. This is particularly useful for companies that want to rework old graphics, screenshots, or incomplete image sources.

But the tool can also give privately scanned photos or souvenir pictures a second life. Since Upscayl runs completely free of charge and locally on your device, your images remain private. This is, of course, an important argument for data-sensitive individuals or companies with strict compliance requirements.

Use artificial intelligence for free with Upscayl:

• Sharpen and enlarge images: Quality is visibly improved

• Can be used locally: no uploads to external servers

• Ideal for enhancing old but still important image material

10. Uberduck AI – AI voices for audio and content

Uberduck AI generates artificial voices from text or converts your own voice into a different one. This allows companies to create very professional and smooth-sounding audio elements for videos, presentations, advertising, or social media.

With the free version, it is only possible to convert a few lines of text, but this can be done several times in a row. For Germany alone, there are more than 30 different voices and styles that you can try out for free. Here you can get a good insight into how AI speech tools work.

Use artificial intelligence for free with Uberduck AI:

•Text-to-speech: clear audio from written text

•Voice-to-voice: convert your own voice into other styles

• Fast audio creation: ideal for online content or presentations

Conclusion

For small and medium-sized businesses, it is now more important than ever to be able to use artificial intelligence free of charge. This provides an opportunity to gain initial experience and identify ways to comprehensively improve workflows (in the long term) with the help of AI. Many organizations are still in the early stages and often do not know what potential AI tools really offer. Free trials gradually develop a feel for which tasks can be particularly well automated or simplified. At the same time, efficiency gains are already being achieved on a small scale.

This is a major advantage, not least because SMEs in particular usually have hardly any resources to completely automate their accounting or customer service in one fell swoop, for example. A steadily growing understanding of the subject matter through the use of smaller technology building blocks will have a positive long-term effect. Companies that familiarize themselves with AI at an early stage will remain more competitive in view of the already immense spread of corresponding applications.
