MaxAI

MaxAI is an AI browser extension that adds a chat sidebar to Chrome and Edge so you can ask about any webpage, summarize videos and documents, translate pages and write better text wherever you work online. It belongs to the all-in-one sidebar family of tools, and its appeal is breadth: reading, research, writing and translation sit in one panel with several AI models to choose from.

What is MaxAI used for?

MaxAI saves the copy, paste and tab switching that comes with using a chatbot in a separate window. The sidebar reads the page you are on and works with it directly.

• Summarizing long articles, research papers and email threads into key points and next steps
• Chatting with a YouTube video to get a summary or find a specific moment
• Asking questions about a PDF or image you open in the browser
• Translating foreign-language pages with the original and translation side by side
• Rewriting, shortening or replying to text in any web form, from LinkedIn to Gmail
• Saving reusable prompts, such as a house writing style, and running them with one click

Who MaxAI is best for

MaxAI suits students, researchers, marketers and knowledge workers who read and write a lot in the browser and want one assistant across every site. It is a good match if you want access to several AI models without paying for each separately. Developers who need deep coding tools, or people who prefer a standalone desktop app over an extension, may find it less useful.

MaxAI pricing

As of October 2026 MaxAI has a free plan at $0 that includes unlimited chats with its free models and 3 chats per day with Pro models. The Pro plan costs $12 per member per month when billed yearly, listed as a limited-time saving, or $30 when billed monthly. Pro adds unlimited Pro model chats, a choice of smarter models, higher file upload limits, image generation and team member management. Check the pricing page for current promotions, since the discount is marked as limited time.

Limitations to keep in mind

• The extension reads page content to work, so review its privacy policy before using it on sensitive internal sites
• Free users get only three advanced model chats per day
• Advertised savings depend on annual billing and may change
• It works in Chrome and Edge, so Safari and Firefox users have fewer options

MaxAI vs alternatives

Sider is the most direct rival, with a similar sidebar, multi-model chat and a large user base, and suits people who want extra features like a wisdom library. Monica bundles chat, writing and image tools in an extension and app, and is worth comparing on price. HARPA AI goes further into automation, monitoring pages and running web tasks for you. Merlin AI is another sidebar option that is popular for summarizing YouTube and writing on social sites. MaxAI wins for users who want a clean, everyday reading and writing companion with a usable free tier and strong translation.

Tips for getting started with MaxAI

Pin the extension and learn the keyboard shortcut to open the sidebar, since speed is the main benefit. Create two or three reusable prompts for tasks you repeat, such as summarizing a paper in five bullets. Save your daily Pro model chats for complex questions and use the free models for quick summaries.
