Frequently asked questions
What is SideDog?
SideDog is an AI assistant that lives in the side panel of Chrome and Microsoft Edge. It reads the page or PDF you are on, so you can ask questions about it, get a summary or a report, translate the whole page, or capture part of the screen and ask about it.
Which browsers does SideDog work in?
Desktop Google Chrome and Microsoft Edge, version 114 or later. The same extension works in both.
Is SideDog free?
Every new account starts with a free trial with a daily usage limit. Paid plans will come later, and you will see the price before you pay.
What does SideDog send to its server?
Only what a question needs: your question, the images you attach and, unless you remove it, the text of the current page. Nothing is sent while you simply browse. Conversations are stored in your browser, and there are no ads or tracking.
Can it read PDFs, charts and images?
PDFs with selectable text are read directly. For charts, images and scanned pages, use the screenshot buttons above the input box: capture the screen, drag an area or pick a single element.
Which languages does SideDog support?
The interface, answers and page translation are available in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, French, German, Spanish, Portuguese (Brazil) and Russian. SideDog follows your browser language, and you can change it in settings.
How do I read a PDF saved on my computer?
Open the PDF in Chrome or Edge, then turn on "Allow access to file URLs" once: open chrome://extensions (or edge://extensions), click Details under SideDog and switch it on. If it is off, SideDog shows an "Open extension settings" button that takes you there. PDFs opened from a website do not need this.
Can SideDog summarize YouTube and Bilibili videos?
Yes, for videos with captions (including auto-generated ones). Open the video, then click "Video outline" in the side panel. You get an overview and the main points in order, each with a timestamp you can click to jump to that moment. On Bilibili, some captions are only available after you sign in to Bilibili.
