Which AI is the best? In 2026, there is no credible answer to this question that involves just one product name. ChatGPT is currently the most versatile all-round solution, but depending on the task, Claude, Perplexity or Gemini may be better suited to your day-to-day work.
It is therefore not just the performance of a model that matters. What matters is which system most reliably supports research, texts, data, files, programming or existing work processes. The question ‘Which AI is best?’ cannot therefore be answered independently of the specific use case. What matters more is: Which AI is best for which purpose – and which solution supports my most important workflow?
Technical benchmarks can highlight differences in performance. However, they only partially reflect real-world work processes, integrations, usability or source access.
A wide range of functions only offers an advantage if those functions are actually needed. A specialised system may be better suited to a specific workflow than a supposedly more powerful all-rounder.
Many typical tasks can already be carried out using free plans. A subscription becomes worthwhile when usage limits, missing features or frequent changes of tools result in a measurable loss of time.
The recommendations in this comparison are not based on a standardised laboratory test using identical prompts. Instead, we evaluate the documented features of the platforms, their areas of focus and their suitability for typical workflows. In doing so, we deliberately distinguish between model performance, feature set, integrations and actual workflow benefits. Depending on the use case, different features are relevant: a powerful language model, multimodal inputs or customisable functions only provide an advantage if the system reliably carries out specific instructions and fits the relevant work process.
The assessment takes particular account of text and file processing, research and sourcing, data analysis, multimodal use cases, programming, integrations, free usage options and typical premium features. Due to rapid technological development, models, features, prices and usage limits can change, in some cases within a matter of months.
| Main purpose | Our assessment | Particularly suitable if … | Consider an alternative if … |
|---|---|---|---|
General use | ChatGPT | Research, text, files, data and images need to be brought together in a single system. | A specialised workflow is almost the only consideration. |
Writing & analysis | Claude | The focus is on long texts, complex documents and conceptual work. | Maximum range of functions is more important. |
Research | Perplexity | Up-to-date information and visible sources are key. | Research is only part of a larger workflow. |
Google Workspace | Gemini | Gmail, Drive, Docs and Sheets are already used extensively. | Work is largely carried out outside the Google ecosystem. |
Programming | Claude / ChatGPT | Code is linked to analysis, documentation or complex tasks. | Deep IDE integration is crucial. |
Learning & explanations | ChatGPT | Clarification, personal materials and varying levels of explanation are required. | Mainly academic source research is required. |
Image generation in an all-round workflow | ChatGPT | Text, analysis and images are to be produced in a single process. | Visual production is the sole focus. |
Which AI is currently the best depends on the most important use case: ChatGPT offers the widest range of capabilities, whilst Claude, Perplexity and Gemini may be better suited to specific workflows. The table is deliberately not a ranking. A tool does not win simply by covering as many categories as possible. It wins when its strengths align with your own most important workflow.
You can subscribe to new applications in just a few minutes. But that alone doesn’t create effective processes. DREIKON combines artificial intelligence with content, SEO, GEO and digital strategy. We analyse where its use actually generates benefits for your business and how search, visibility and the customer journey change as a result.
Anyone wishing to manage research, texts, files, images and data using a single system will currently find ChatGPT offers a particularly flexible solution. The assistant combines traditional dialogue functions with web search, file and data management, and multimodal tools. In day-to-day work, for example, it can be used to organise notes, analyse documents, create content, evaluate data and research information without constantly switching between different applications. ChatGPT isn’t the best AI for every task. However, as an all-rounder, the platform covers a particularly wide range of applications to a high standard.
Anyone wishing to know which AI is best for text generation should compare Claude and ChatGPT in particular detail.
For extensive texts, conceptual work and complex documents, Claude is one of the most interesting options. This becomes particularly relevant when long briefs, broader contexts or extensive source material need to be processed. Text creation and generation are not just about generating new content as quickly as possible. The crucial factor is whether the generated texts consistently take into account specifications, tone, context and existing materials.
ChatGPT remains a strong alternative when writing is closely linked to research, data analysis, images or other tasks. On the other hand, those who mainly optimise the wording of individual existing phrases may also wish to consider specialised tools such as DeepL Write. Good AI-generated texts do not come about solely through the right tool. Expert review, editing, an understanding of the brand and a clear purpose remain essential. In addition to the platforms compared here, there are other specialised or alternative solutions such as Mistral, Neuroflash or Grammarly. Whilst they are not the focus of this comparison, they can be examined further for specific requirements.
When the focus is on timeliness, sources and traceability, Perplexity has a clear structural focus. The platform is strongly positioned as a research and response system and links answers directly to web sources. This is helpful, for example, with market analyses, competitive research, current developments or getting to grips with new topics.
Visible source citations make verification easier, but are not in themselves proof of quality. Perplexity facilitates source verification, but does not replace it. ChatGPT and Gemini remain worthwhile options when research is to be integrated directly into analysis, content, files or other work processes.
When it comes to programming, it is not enough simply to compare code generated in isolation. Professional development encompasses existing codebases, debugging, testing, documentation and established standards. Claude and ChatGPT are among the most versatile solutions for development tasks. However, which system is more suitable depends heavily on how development is actually organised.
For professional developers, therefore, specialised coding tools such as Cursor or GitHub Copilot may prove more important than a direct comparison of two chat assistants. Integration into the actual development process can boost productivity more than a slight advantage with a single prompt. Even for users without in-depth programming knowledge, assistants can be helpful in understanding code, interpreting error messages or making simple adjustments. Nevertheless, professional software development requires expert oversight and robust development processes.
ChatGPT is particularly versatile for explanations and dialogue-based learning. Users can ask follow-up questions, provide their own materials and have topics explained at different levels of knowledge. Gemini can be useful if learning materials are already stored in Google services. For current or academic questions, care should also be taken to ensure sources are reliable.
AI works most effectively in learning as a conversation partner – not as a source of unverified model answers.
For occasional images, presentations, social media designs or simple visualisations, an integrated solution is often more efficient than a separate specialist service. ChatGPT is therefore particularly useful when image generation forms part of a larger text, research or analysis process. If visual production itself is the main focus, specialised image generators such as Midjourney or Adobe Firefly should be compared separately. When making a selection, you should also consider whether you only need to generate individual images or require a broader multimodal workflow. For example, anyone wishing to combine image generation with animation or video editing should compare specialised creative solutions separately.
Which AI is best when not just individual users but entire teams are working with it? For businesses, the decision changes significantly. What matters here is not just the quality of a single answer, but how securely, cost-effectively and reliably a system can be integrated into existing workflows.
ChatGPT can be used as a versatile platform for research, analysis, content creation and knowledge work. Gemini becomes more relevant if Google Workspace is already deeply embedded within the organisation. The...
... Claude, the assistant developed by Anthropic, is particularly useful when longer texts, document analysis, extensive source material and complex interrelationships form part of day-to-day work. Perplexity can offer clearly defined benefits in market, competitive and topic research. For businesses, artificial intelligence also becomes of interest where routine tasks need to be automated, large volumes of data processed more quickly, or AI-supported workflows established. However, such automation does not automatically increase productivity. The key factor is whether a recurring process can be usefully automated and whether results can still be reliably monitored.
Management and marketing leaders should therefore factor additional criteria into their decision-making: data requirements, user management, the existing software landscape, governance, integrations and actual frequency of use. The best AI for a company is not necessarily the one with the most features . It is the one that improves a relevant process without simultaneously creating new operational risks or unnecessary complexity. Particularly in business applications, an assistant should not only carry out tasks more efficiently, but also present information in a way that supports better decision-making.
In marketing, it is the process chain that matters more than any single tool. Research, content creation, data analysis, campaign planning and visual production each have their own specific requirements. An all-round assistant can combine several of these steps, whilst specialised systems offer advantages in specific areas of application and for particular tasks.
The question is no longer simply: Which tool writes the best copy? The more important question is: At which stage of the marketing process should artificial intelligence save time, enable better decisions or improve quality?
Even in SEO and Generative Engine Optimisation, there is no single workflow that AI can cover in its entirety. Search intent, topic research, competitive analysis, data processing, content creation and the optimisation of existing content all present different requirements. For SEO and GEO, therefore, it is less important which assistant is better overall. What matters is how AI is integrated into research, data analysis, content production and optimisation. None of the systems can replace search intent, subject-matter expertise, technical SEO, entities or digital authority.
ChatGPT, Claude, Gemini and Perplexity overlap in many functions. What matters, therefore, is not so much what is fundamentally possible, but rather the specific focus of each platform. The question of which AI is better can only be meaningfully answered in the context of a specific task.
ChatGPT combines dialogue, research, file and data management, images and other tools within a single platform. It is precisely this breadth that makes the system appealing to users whose tasks change regularly.
Claude is developed by the AI company Anthropic and is particularly useful when longer texts, extensive documents, complex interrelationships or development tasks characterise your day-to-day work.
Gemini is particularly appealing in environments where Gmail, Drive, Docs, Sheets and other Google services already form the backbone of the daily workflow.
Perplexity places a particularly strong emphasis on web research and sourcing. This makes the platform suitable for users who want to quickly familiarise themselves with new topics and then verify statements directly.
| Criterion | ChatGPT | Claude | Gemini | Perplexity |
|---|---|---|---|---|
Focus | Broad working platform | Knowledge- and document-based work | Google integration | Web research |
Source referencing | ✅ Integrated | Available | ✅ Integrated | Core principle |
Image generation | ✅ Integrated | Not a focus | ✅ Integrated | Depends on the service |
Ecosystem | ✅ Broad | More focused | Google-centred | Research-centred |
Free to use | ✅ Yes | ✅ Yes | ✅ Yes | ✅ Yes |
Once again, this table illustrates why a blanket question such as ‘Which AI is best?’ often falls short. ChatGPT offers a particularly wide range of capabilities. Claude focuses on complex knowledge and development work. Gemini benefits from its integration with the Google ecosystem. Perplexity places the emphasis on research and sources.
A premium subscription is not worth it simply because it offers better performance. It is worth it if it measurably improves a frequently used workflow or if existing limits regularly cost you time. In 2026, the prices for paid subscriptions were still very close to one another. ChatGPT Plus and Claude Pro are both priced at US$20 per month. In Germany, Google AI Pro costs €21.99 per month, whilst Perplexity Pro costs US$20 per month or US$200 per year.
Price differences of just a few euros are usually less relevant than the actual productivity gains. If a system saves several hours each month or makes an important process more reliable, this significantly changes the cost-benefit analysis. Price and tariff details should be checked again with the respective providers immediately prior to publication.
| Usage scenario | Classification |
|---|---|
AI only supports isolated tasks | A free basic version is often sufficient to get started. |
Usage limits regularly cause delays | A premium subscription may be the more productive choice. |
Advanced features regularly save time | A paid subscription can pay for itself through the time saved. |
A business-critical specialised workflow takes centre stage | A specialised AI tool can deliver greater benefits. |
Several clearly defined processes require different strengths | Multiple AI systems make sense if the additional benefits justify the higher costs and added complexity. |
Don’t start with a list of products. First, define the task for which the AI is intended to be of the greatest benefit: research, writing, programming, analysis, learning or a combination of these in day-to-day work.
The technical environment can be more important than minor differences between models. Someone who works in Google Workspace on a daily basis will assess Gemini differently from a company with a highly diverse software stack.
If possible, start by using the free version. Not a demo exercise, but real-world tasks: a typical document, a real-life research project or a regularly recurring process.
A subscription makes sense when a specific bottleneck becomes apparent. It is not additional features that justify the price, but rather more usable output, less time spent on corrections, or less lost working time.
Anyone wanting to know which AI is currently the best will still not find a one-size-fits-all answer in 2026 . For versatile use, ChatGPT is currently our most widely recommended option. However, if you have a specific focus, you should base your decision on your workflow rather than on an overall ranking: text and document processing, research or existing software ecosystems can all influence your choice. There is therefore no single ‘best’ AI. The key factor is which solution most reliably supports your most important process. Choose the task first. Then choose the tool.
No single alternative is better across all areas of application. Claude may be the more suitable choice for text and knowledge-based work, Perplexity for research, and Gemini for Google-centred workflows.
ChatGPT Free is a strong choice for a versatile introduction. Anyone primarily researching up-to-date information and sources should also try Perplexity.
Claude is particularly useful for extensive texts, documents and demanding editing tasks. ChatGPT offers advantages when text creation and generation need to be combined with research, data or other tasks.
Claude and ChatGPT are among the most versatile solutions for coding tasks. For professional development workflows, specialised tools such as Cursor or GitHub Copilot may also be useful.
Perplexity is particularly geared towards up-to-date web research and visible sources. ChatGPT or Gemini may be a better fit if the research is to feed directly into further analysis or work processes.
