MaxAI
AI browser extension with 2M+ users bringing ChatGPT, Claude, and Gemini to any webpage - summarize, translate, and chat without switching browser tabs.
MaxAI.me is a browser extension for Chrome, Edge, Firefox, and Safari that overlays multi-model AI access on any webpage, email, or document without leaving the current tab. Available since 2023 and reporting 2 million+ users, MaxAI provides access to GPT-4o, Claude 3.5, Gemini 1.5, Perplexity, and Llama 3 from a unified interface with context awareness of the current page content. Users highlight any text to instantly get AI explanations, translations, rewrites, or summaries from a floating sidebar, read entire web articles or YouTube transcripts as AI summaries, and compose email replies with AI assistance in Gmail and Outlook without switching to a separate chat window. The Pro plan at $20/month includes unlimited AI model access and advanced features while the free tier provides daily credits sufficient for light users.
Key Features
- Floating AI sidebar overlays any webpage, PDF, Google Doc, or email with access to ChatGPT, Claude, Gemini, and Llama 3 without opening a new browser tab
- Highlight-to-chat selects any text on any webpage and instantly sends it to the AI sidebar with right-click options for explain, translate, summarize, or rewrite
- YouTube and article summarization extracts the transcript or full article text and summarizes it in seconds to evaluate reading priority without watching the full content
- Gmail and Outlook integration adds an AI reply button to email compose windows that drafts responses based on the incoming message thread context
- Multi-model selector switches between ChatGPT, Claude, Gemini, and Perplexity within the same conversation to compare answers from different models for the same question
- Text-to-speech reads AI responses and selected page content aloud for hands-free consumption while multitasking or reviewing long research outputs
- PDF reader with AI Q&A opens any PDF directly in the browser and enables question-answering against the full document content from the sidebar
Use Cases
- Researchers reading academic papers who highlight confusing terminology for instant AI explanation and summarize the full paper in 30 seconds before committing to a full read
- Professionals replying to email who use AI reply drafts for routine correspondence - status updates, meeting requests, and vendor responses - without context switching
- Students studying with textbooks and online resources who use highlight-to-explain to get instant clarifications and alternative explanations for difficult concepts
- Developers reading API documentation who ask the AI sidebar to generate code examples for the method they are reading without leaving the documentation tab
Pros
- Works on any webpage, PDF, and in Gmail without integration setup - no API keys, no copy-pasting context, just install and start using AI on any content in any tab
- Multi-model access in one extension replaces separate ChatGPT, Claude, and Gemini tabs - switching models takes one click rather than opening multiple browser tabs
- Free tier with daily credits covers typical light-to-medium use without payment - 2M+ users confirm the extension delivers real value before the Pro upgrade
Cons
- Free tier daily credit limits run out quickly for heavy research or writing use cases - users hitting limits mid-session must wait or upgrade to Pro
- Privacy implications of a browser extension with access to all webpage content require reviewing the privacy policy - the extension sees every page visited while active
- Floating UI element on every page can be visually intrusive - the sidebar cannot always be hidden without disabling the extension entirely
