It depends on what you want and where you are. Currently, Claude 2 is only available in the US and the UK so you need a VPN with servers in those countries to access the service from anywhere else. In comparison, ChatGPT and Bard are now available in most regions. That said, Claude is free to use and can create and analyze huge blocks of data — up to 100K tokens or 75,000 words at a time. It also can work with up to 5 files (PDFs, CSV, DOCX, RTF, HTML, and TXT files) with a size of up to 10MB each. ChatGPT’s free version has a token context length of around 8000 (though you can pay for up to 32K tokens with a Plus account). Bard is free to use but hasn’t made its token length publicly available. Claude AI can’t scan the web though. ChatGPT 3 (the free version) can’t do this either, but you can pay for a Plus or Enterprise account to use ChatGPT 4, which can. On the other hand, Bard is automatically connected to the internet at no extra cost. While the lack of internet access limits Claude somewhat, Anthropic claims that its chatbot is less likely to produce harmful responses as a result.
