サテライトAI・サイドパネルAI is a Chrome extension from Sateraito Office that brings an AI side panel into Gmail. Instead of switching tabs to a chatbot, you work with AI directly alongside your inbox: composing new messages, drafting replies, expanding or shortening text, and correcting outgoing mail. It also summarizes individual emails and full threads, and can surface potential issues in a conversation before you send.
Beyond email, the extension extends AI help to the pages you browse. You can ask questions using a page's URL, transcribe and analyze YouTube comments, ask about an image captured from your screen or clipboard, and query local files you upload. Files attached to Gmail messages and stored in Google Drive can also be questioned. Meeting scheduling through Google Calendar integration rounds out the productivity set, and a newer feature analyzes reviews on Google Maps.
According to its Chrome Web Store listing, the extension has a 5.0 rating, a few hundred users, and version 1.7.8 with an update in late 2026. It is published in English and Japanese by Sateraito Office, a Japanese vendor, and the developer states that it does not collect or use your data. The store notes that summarization of Google search results is available only in the paid version.
Generate replies, tighten wording, and check outgoing mail for problems before hitting send.
Compress a long thread into a summary and extract action points without reading every message.
Ask about a page, image, or uploaded file and get answers without copying content into a separate chatbot.
Analyze and transcribe YouTube comments and use Drive or Gmail attachments as AI context.
