What is MaxAI?
MaxAI is a browser extension for Chromium-based browsers such as Chrome and Edge, with a web app version as well. It adds an AI sidebar that stays open while you browse, so you can ask questions without switching tabs or copy-pasting text. The sidebar can read the current webpage, a YouTube video, a PDF, an image or a file, and answer based on that content, with sources cited.
In practice you can summarize articles and YouTube videos, explain complex passages or code, rewrite or proofread text directly in web forms, draft replies to emails and social media messages, translate pages side by side with the original, and generate images from text. The plans offer access to several AI models, including GPT, Claude, Gemini and others, selectable per conversation.
