*Legend: + = affordable, ++ = medium, +++ = expensive* ## What makes IONOS GPT stand out? [IONOS GPT](https://www.ionos.co.uk/momentum/ionos-gpt "Your sovereign AI assistant for greater productivity") is built with European requirements in mind. It suits individuals, organisations and businesses that want to work productively with AI while maintaining data control, transparency and compliance with European law. ### Four specialised AI assistants IONOS GPT is divided into four separate [AI assistants](https://www.ionos.co.uk/digitalguide/websites/web-development/ai-assistants/): - **AI Writer:** supports content creation, editorial work and internal communication - **AI Designer:** generates visual ideas from text for marketing or social media - **AI Programmer:** assists with code, documentation and technical explanations - **AI All Rounder:** handles general questions and a wide variety of everyday tasks This setup helps users select the right assistant for individual tasks. It also makes it easier to get started, even for those without technical expertise. ### Simple access via web browser IONOS GPT runs directly in the browser. After free registration, you simply sign in to get started. Input is given through a familiar chat interface. For deeper integration, you can connect processes via the **IONOS AI Model Hub** [API](https://www.ionos.co.uk/digitalguide/websites/web-development/what-is-an-api/). ### Hosting in the EU with strict data protection A clear benefit of IONOS GPT is hosting in certified European data centres. All data stays within the EU, providing certainty for authorities, SMEs and sectors where confidentiality is essential. The platform is fully [GDPR](https://www.ionos.com/digitalguide/websites/digital-law/general-data-protection-regulation-new-rules-for-businesses/)-compliant and does not use your prompts for training. This sets it apart from many US cloud-based services such as Claude or Copilot. ### Company-specific knowledge bases IONOS GPT allows you to create **company-specific knowledge areas**. You can upload documents or enter content directly into the interface. The AI then uses this material for contextual responses. This means it can answer questions not only in general terms but also with reference to your internal information. Crucially, this information is never disclosed externally. ### Prompting made easier The assistants provide intelligent **prompt suggestions** that guide users towards clear, effective inputs. This improves result quality and saves time on repetitive tasks. ### Reasoning Mode IONOS GPT includes a **Reasoning Mode** for trickier tasks. Rather than jumping straight to an answer, the AI works through complex queries step by step, checking its progress along the way and correcting any errors before giving you a final response. This makes it well suited to financial modelling, contract analysis and complex logic problems – all with no monthly usage limits. ### Web search The built-in **web search function** lets IONOS GPT pull in up-to-date information from across the web. So rather than solely relying on its trained knowledge, it can draw on sources and data that are refreshed daily. ### Designed with transparency in mind IONOS GPT focuses on structure, openness and **full GDPR compliance**. Whereas Claude’s strengths lie in being able to process large volumes of text and Copilot is deeply integrated into Microsoft products, IONOS GPT maintains its independence. It prioritises transparency, avoiding opaque data flows and black-box logic. ## What are Claude’s main features? Claude supports a wide range of applications, from text and code to document processing and visual analysis. It is particularly suited to organisations that need long context handling and multimodal inputs. ### Multimodal models with large context window Claude uses **proprietary AI models** – Haiku, Sonnet, and Opus – each tailored to different performance levels. The top-tier Opus model can process up to one million tokens in context, enabling it to handle complex analyses, long documents or source code. This large capacity allows Claude to excel in tasks that require deep understanding of large amounts of text. ### Strong support for coding and logic Claude includes features such as **Claude Code** to streamline programming work. The model can identify errors, suggest improvements and follow logical structures in code. On many software benchmarks, Claude performs at a similar level to or even outperforms ChatGPT, offering developers a structured and responsive environment for larger projects. ### Ethical development approach Anthropic trains Claude using **Constitutional AI**, which incorporates ethical guidelines alongside user input. This approach is designed to ensure responsible and consistent answers, even for sensitive or safety-critical topics. ### Handling visual information Claude’s **multimodal** design enables it to interpret images, screenshots and tables. This helps with use cases ranging from design reviews to technical analysis and detailed reporting, where text and visuals need to be considered together. ### Working with documents and projects You can upload documents such as PDFs or Word files for Claude to analyse. It can summarise content or answer queries directly from the file. Long context windows also support extended projects with multiple documents. ### App creation with ‘Artifacts’ Claude can generate **mini apps** directly in the chat, including simple tools, workflows or games. This lowers the barrier for non-developers and enables interactive content. ### API integration and scalability Claude is accessible via APIs and can be connected to platforms such as **Vertex AI**. Billing is usage-based, making it easy to scale up or down. ## IONOS GPT vs. Claude: which should you use? IONOS GPT is ideal for users who value security and straightforward operation. Claude excels at handling large datasets and multimodal inputs, though it typically requires more technical know-how. While Claude offers flexibility and high performance, IONOS GPT provides stronger control over infrastructure and compliance with European data protection standards. ### When to use IONOS GPT - **Content creation with data control:** IONOS GPT is an excellent choice for organisations that handle sensitive information and need to ensure their workflows remain legally compliant. Editorial teams, public authorities, and educational institutions particularly benefit from GDPR-compliant processing, with the added reassurance that your prompts are not used for model training. - **Support for SMEs and freelancers:** Thanks to its simple browser interface, IONOS GPT is perfect for small businesses and self-employed professionals. It allows you to generate content, automate tasks, and analyse documents with no technical knowledge required. - **Project management support:** IONOS GPT can be a great help for teams looking to create reports, summaries, and presentations. The AI assists in structuring drafts, saving time and making the preparation of materials more efficient. - **Regulated industries:** Organisations in sectors like healthcare, finance, and the public sector appreciate IONOS GPT’s EU-based hosting and commitment to transparent data handling, ensuring that no data leaves Europe. ### When to use Claude - **Software development with extensive context needs:** Claude performs well at complex programming tasks due to its deep contextual understanding. Developers can use it to analyse, improve, and document large codebases, making it the ideal choice for handling extensive, intricate code. - **Document and data analysis in research and consultancy:** Claude is particularly well suited for organisations that handle large-scale data analysis. Research institutes and consultancy teams benefit from its ability to process long documents, complex datasets, and detailed reports. However, Claude’s hosting and data protection are governed by US law, not GDPR. - **Automation of complex workflows:** Claude helps larger organisations optimise internal processes. With API access and the ability to generate smaller applications directly within the chat, the platform can be easily integrated into existing systems and scaled to suit the organisation’s needs.
