Almost everyone who works at a computer now uses an AI assistant or is thinking about it. The three big names are OpenAI's ChatGPT, Google's Gemini and Anthropic's Claude. All can write, summarize, translate, answer questions and help with code, and all improve every few months. So the right question is not 'which is best' but 'which suits me'.

Question one: which ecosystem do you live in? If you work all day in Gmail, Google Docs and Google Calendar, you will benefit from Gemini's links to those tools. In a Microsoft environment you will meet Copilot, which is partly based on OpenAI technology. Question two: what do you do most? Long-form writing, document analysis, coding, image creation or voice conversation. Each tool has strengths that shift with every update. The best approach is to try the same real task in two or three tools and compare.

Question three: how important is Hebrew to you? All the major tools write reasonable to good Hebrew, but differences show in phrasing, vowel marks and slang; test them on real text from your work. Question four: do you need the paid version? Free versions are enough for most everyday use; paid versions usually offer stronger models, more usage and advanced tools. Question five: what is the privacy policy? Check in settings whether your conversations are used to train models and whether you can turn that off.

And five rules for safe use, whatever the tool. One: do not paste sensitive information such as customer details, internal work documents, ID numbers or passwords unless your organization has approved a tool for that. Two: check facts. These tools sound confident even when wrong and sometimes invent numbers, quotes and sources. Three: be careful with medical, legal and financial advice; treat it as a starting point, not a decision. Four: remember the answer depends on the question; the more context you give, the better. Five: beware fake apps impersonating the well-known tools; download only from official stores.

Bottom line: the differences between the big tools are smaller than the ads suggest, and they keep changing. What really makes the difference is how you use them. Pick one tool, learn it well, and check every few months whether something else suits you better.
