Dia Browser

Dia's sidebar chat works on the pages you have open, so you can ask about the article on screen instead of copying text into a separate chatbot. You can reference a single tab or several at once, which turns a stack of open pages into one conversation. It's the feature that separates Dia from a normal browser with an AI attachment added on, and it's why people treat it as a true AI browsing assistant.

Skills are reusable shortcuts that mix official presets with ones you build yourself. Current built-in Skills cover summarizing, fact-checking, browsing history analysis, outlining, and productivity planning. Once you save a Skill for a task you repeat, you run it again with a click instead of retyping the same prompt.

Memory lets Dia learn your preferences, writing style, and the sites you visit most. Over time the assistant answers closer to how you'd phrase things yourself, which reduces cleanup after it drafts something. The catch is that it only works well if you actually keep using the browser, since a fresh install hasn't learned anything yet.

You can add files to a conversation and pair them with what's on screen. That means asking about a PDF while also citing a webpage, without switching tools. It's handy when the answer depends on both a document you downloaded and a source you're reading live.

Dia ships study features that turn notes, lectures, and readings into flashcards, quizzes, and custom study guides. For students this covers a lot of the manual work of building revision material by hand. It's a narrow audience, but for that audience it's one of the more concrete additions.

Because your history and preferences live in the browser, Dia can carry context across sessions rather than starting from zero each time. Pro adds extended cross-session Memory and chatting across all open tabs at once. This is where the paid plan earns its place for heavy users.
