Our verdict
Brave Leo is an AI assistant built into the Brave browser, aimed at people who want help with the page they are reading and do not mind using Brave. Duck.ai is a standalone anonymous chat site for several AI models, aimed at people who want to ask general questions privately without signing up. They overlap on privacy, but they serve different purposes: one works inside a browser, the other works as a separate chat tool.
Pick Brave Leo if you already use the Brave browser and want quick summaries of pages or videos with no chat logs kept.
Pick Duck.ai if you want to ask general questions to several AI models anonymously without creating an account.
