What's a good free alternative to ChatGPT that doesn't require an account?

You can use several capable AI chatbots without creating an account, with Perplexity AI and Microsoft Copilot being the most accessible free alternatives to ChatGPT right now. Perplexity works as a search-savvy assistant that cites its sources — just go to the site and start typing. No signup needed. Copilot, built into the Bing search engine, offers a similar no-login experience and even lets you upload images for analysis. I've found that the trade-off is usually session limits or slightly less nuanced creative writing compared to a paid ChatGPT plan. For quick factual lookups or summarizing a webpage, these tools work surprisingly well. A lesser-known option is You.com's chat mode, which also skips the account wall. The big catch? None of these save your conversation history without an account. So if you're working on a longer project, you'll lose your thread when you close the browser. Another thing to watch: the free, no-account versions often run on slightly older AI models. You're not getting the absolute latest brain, but for 80% of everyday questions, the difference is barely noticeable. If you need reliable, repeatable outputs for content creation without messing with prompts at all, you might look at a zero-prompt tool instead.
