> AI assistants tested on everyday work: automate email, calendars, research and documents, handle privacy, know the limits. For freelancers and small firms.

- [AI Email Assistant: What to Hand Over and What to Keep](https://dein-privater-assistent.de/en/everyday-automation/ai-email-assistant/): An AI email assistant is worth using for drafts, thread summaries and replies you keep putting off. Give it the facts, the tone and the goal of the message, cap the length, and always read the draft before sending. Built-in tools in Outlook and Gmail handle routine replies; a chat assistant with a template handles the tricky ones.
- [AI Meeting Notes: Tools, a Prompt That Works, Consent](https://dein-privater-assistent.de/en/everyday-automation/ai-meeting-notes/): AI meeting notes come from two steps: speech recognition turns the call into a transcript, then a language model condenses it into decisions, action items with owners and open questions. Use a fixed template, check names and dates against the transcript, and tell everyone up front that the meeting is being transcribed. Secret recording is illegal in many places.
- [Summarize a PDF with AI Without Missing Pages](https://dein-privater-assistent.de/en/everyday-automation/summarize-pdf-with-ai/): To summarize a PDF with AI, upload it to an assistant such as ChatGPT, Claude or Gemini and tell it the purpose, the sections you want and a length. The summary becomes trustworthy once the model gives a page number and a short verbatim quote for every claim. Run scanned PDFs through text recognition first, or parts of them may never be read.
- [AI Scheduling Assistant: Four Levels, From Simple to Auto](https://dein-privater-assistent.de/en/everyday-automation/ai-scheduling-assistant/): An AI scheduling assistant works at one of four levels: booking pages where people pick a free slot themselves; assistants inside Outlook or Google Calendar that suggest times; tools that place tasks into calendar gaps automatically; and chat assistants that sort your week from a list. For most freelancers, the first level removes the biggest headache.
- [ChatGPT vs Claude: Which One for Which Job](https://dein-privater-assistent.de/en/tools/chatgpt-vs-claude/): ChatGPT is the broader package, with image generation, a polished voice mode and a huge library of custom GPTs. Claude stands out with long documents, careful writing and project workspaces built around your own files. Both charge $20 a month for an individual plan and have usable free tiers. Your own test with real tasks should settle it.
- [How to Write AI Prompts: Six Parts, Real Examples](https://dein-privater-assistent.de/en/tools/how-to-write-ai-prompts/): A good AI prompt tells the model what to do, why you need it, what material to use and what the answer should look like. Adding one to three examples of the output you want improves results noticeably. Anthropic's guide offers a simple test: if a colleague with no background would be confused by your prompt, the model will be too.
- [Copilot vs ChatGPT: Which One Fits a Microsoft 365 Office](https://dein-privater-assistent.de/en/tools/copilot-vs-chatgpt/): If your company runs on Microsoft 365, you probably already have Copilot Chat at no extra cost: a web-grounded chat with enterprise data protection. The full Microsoft 365 Copilot is a paid add-on that reads your mail, files and calendar. ChatGPT is the more versatile standalone tool. For Microsoft 365 offices, Copilot Chat is the obvious place to start.
- [Build Your Own AI Assistant Without Code: A Template](https://dein-privater-assistent.de/en/tools/build-your-own-ai-assistant/): To build your own AI assistant, set up a custom GPT or project in ChatGPT, a project in Claude, a Gem in Gemini or an agent in Copilot, then add standing instructions and reference files. The model isn't retrained; it reads your setup at the start of every chat. Precise instructions, clean files and a ten-question test decide whether it works.
- [Is ChatGPT GDPR Compliant? What Businesses Need to Do](https://dein-privater-assistent.de/en/privacy-and-limits/chatgpt-gdpr/): ChatGPT isn't GDPR compliant or non-compliant by itself; it depends on how you use it. Text with no personal data is unproblematic. Client data needs a business plan with a data processing agreement, training off by default and internal rules. Personal accounts holding client data, and special categories such as health data, are off limits.
- [AI Hallucinations: Why They Happen and How to Catch Them](https://dein-privater-assistent.de/en/privacy-and-limits/ai-hallucinations/): AI hallucinations are answers that read fluently and plausibly but are wrong or invented: sources, figures, court cases, quotes. They happen because language models generate likely text and are rewarded for guessing during training and evaluation. Supplying your own sources, allowing "I don't know", demanding verbatim evidence and cross-checking catch most of them.
- [AI Act AI Literacy: What Article 4 Asks of Small Firms](https://dein-privater-assistent.de/en/privacy-and-limits/ai-act-ai-literacy/): Since February 2025, Article 4 of the EU AI Act has required organisations that use AI systems to take steps on their staff's AI literacy. The July 2026 Digital Omnibus reworded it: companies must take measures to support AI literacy, without guaranteeing any particular level. No certificate is required. A short training session, written rules and a simple record usually cover it.
- [Do You Have to Disclose AI-Generated Content? EU Rules](https://dein-privater-assistent.de/en/privacy-and-limits/disclose-ai-generated-content/): Since 2 August 2026, Article 50 of the EU AI Act has required businesses to disclose deepfakes, meaning realistic AI-generated or manipulated images, video or audio, and AI-generated text published to inform the public on matters of public interest unless a person reviewed it and holds editorial responsibility. Ordinary marketing copy, emails and edited blog posts usually need no label.
