FAQ
Short, clear answers for anyone who wants to use AI tools professionally, privately, in studies or in marketing.
FAQ
AI tools are software products that make use of models for language, images, audio, video, search or automation.
Many tools have free versions, but they come with limits on models, speed, exports, team features or usage.
ChatGPT is a strong default choice, but for sources, long texts, Office workflows or presentations other tools may be a better fit.
If you want to compare several models or move projects forward with context, a multi-model interface is more practical than many separate tabs.
It depends on the provider, the subscription tier, the contract and the data you enter. Confidential information should not be entered carelessly.
Yes. Hallucinations, outdated information and incorrect sources are possible. Critical claims must be verified.
For search engine optimization, research, briefing, structure, content optimization and internal links are essential. Human review remains important.
Gamma, Canva, Copilot, SlidesAI and MultipleChat workflows can help with structure, storytelling and drafting slides.
Companies should review GDPR, data processing agreements, storage location, deletion schedules, role-based access rights and training on user data. Sensitive personal data belongs only in approved systems with clear internal rules.
For companies operating in the EU, GDPR is central. Check the purpose, transparency, data security, processing via third parties and transfers to third countries. In particular with US-based or international providers, contractual guarantees and technical safeguards should be reviewed.
GDPR applies. Important points are the legal basis, oversight of data processors, documentation, a possible data protection impact assessment and clear instructions for employees. Authorities, schools and regulated sectors should additionally follow internal requirements.
Data protection
AI tools can be productive, but data protection is not a detail to tack on at the end of tool selection. Before using a tool, teams should clarify which data may be entered, where it is processed, who has access and how the results are checked.
For companies, GDPR, data processing agreements, storage location, deletion policy, role-based access rights and internal agreements are especially important. Check whether the provider offers a data processing agreement, how long prompts and files are retained and whether inputs are used for training. Customer data, employee data, contract contents and health data belong only in controlled systems with clear approvals.
In the EU, the General Data Protection Regulation (GDPR) is central. Especially relevant are purpose limitation, transparency, data security, processing via third parties and transfers abroad. If an AI tool processes data outside the EU or EEA, companies should check what guarantees, standard contractual clauses or other safeguards are in place.
Organizations in the EU are likewise subject to GDPR. In practice, a data protection impact assessment for high-risk cases, clear legal bases, documentation, oversight of data processors and staff training are important. Authorities, educational institutions and regulated sectors often have additional internal requirements.
