MaxAI

Freemium

MaxAI is a browser extension that puts AI chat, writing, and summaries in a sidebar. It works in Chat & Assistants. You click a button or press a key, and the sidebar opens next to whatever page you are on.

You can rewrite text, translate, ask questions about a PDF, or get a video summary without leaving your tab. It bundles access to GPT-4, Claude, and Gemini behind one interface.

The free plan runs out fast. Paid plans start at $12/month with annual billing, or $20–$30 month-to-month. Credits expire monthly with no rollover.

Open it if you use Chrome or Edge and need quick in-page help every day. Skip it if you hate subscription traps or need to train your own AI.

It fits when the job looks like this:

• Chrome/Edge users doing 5+ daily in-page AI actions: You save time on rewrites and replies. The sidebar lives where you work.
• Researchers summarizing dense papers and videos:You getfast takeaways without copy-paste. You still check the details yourself.
• Writers and editors doing web-based content work: You rewrite sentences and adjust tone while keeping the page open.
• Marketers drafting high email and social volume: You generate replies in context. You edit heavily before sending.
• People comparing model outputs side by side: You switch GPT-4, Claude, and Gemini without multiple tabs.
• Anyone frustrated with tab-switching to chat interfaces: You ask questions about the current page. The AI sees what you see.
• People with one AI subscription who want to test others: You try multiple models from one bill. You pay monthly or face annual lock-in.
• High-volume readers who summarize articles and videos: You crush long content fast. You need the Pro tier to skip limits.

These parts actually work:

• The sidebar follows you: It opens on any page with a key shortcut. You never leave your tab.
• Multi-model in one place: You pick GPT-4, Claude, or Gemini. The best model fits the job.
• Page-aware questions: You ask about what you are reading. The AI uses the current page as context.
• Functional free tier: You test the workflow before paying. Three Pro queries per day show you the limits.
• Own API key option: You bring your own OpenAI key. You bypass credit limits on premium models.

Skip it when these matter:

• Credits vanish monthly: You pay for what you do not use. There is no rollover or refund.
• Hidden cancellation: You hunt for the cancel button. Auto-renewal hits with no warning.
• Broken features burn credits: Website analysis fails and still costs you. PDF scans stall halfway.
• Support ignores you: Refund requests sit for days. Billing issues get evasive answers.
• No mobile app: You are stuck at your desk. Android users get nothing.
• Formulaic output: You get basic, detectable text. Heavy editing is required.
