About this extension
UltraAI puts an AI assistant in your Firefox sidebar that can see what you're working on. Ask about the page you're reading, compare a group of tabs, or rewrite and translate text without copying and pasting between tabs.

WHAT YOU CAN DO
• Understand any page in seconds. Ask for a summary, key takeaways, an explanation or action items for the tab you're on, or just for the text you've highlighted.
• Summarize YouTube videos. On a video page, ask about the video itself.
• Ask across tabs. Put tabs in the "UltraAI tabs" group, or pick any tab group in the window, and ask one question across all of them.
• Rewrite where you write. Select text and right-click "Ask UltraAI about…", or use the ✦ button next to text boxes: rewrite, fix grammar, shorten, summarize, reply or translate. Then insert the result or replace your selection.
• Draft emails faster. In Gmail, Outlook, Yahoo Mail and other webmail, draft a reply to the open thread or turn rough notes into a full email. The draft goes into your reply box. You edit and send it yourself; UltraAI never sends email for you.
• Ask about what's on screen. Capture the visible page or drag out a region, or attach images, PDFs and text files.
• Pick up where you left off. Conversations are saved to your UltraAI account and listed in the sidebar.

KEYBOARD SHORTCUTS

• Open UltraAI: Ctrl/⌘+Shift+U (Alt+Shift+U on Linux)
• Capture an area: Alt+Shift+A
• Capture the visible page: Alt+Shift+W
• Change them at about:addons → ⚙ → Manage Extension Shortcuts.

GOOD TO KNOW
• Account and plans: You need a Ultra AI account (free or paid)
• You control site access: allow all sites on first run, or one site at a time.
• Page text is sent only with a request you make. Files and captures upload as soon as you attach them.
• Email text and the content of other tabs are sent only after you allow them in Firefox's permission prompt.
• Your request and the content sent with it go to UltraAI's servers and the AI model providers that generate the answer.
• No ads, no data sale. It never reads password or payment fields and never runs in private windows.
