Liner

What it does

Liner places an AI sidebar next to whatever you are reading in Chrome, summarizing YouTube videos, PDFs and web pages and answering follow-up questions. It is meant for students, researchers and anyone who reads a lot and wants to keep track of key points and highlights.

Key features

• Summarizes YouTube videos with key points and timestamps
• Condenses long PDFs and academic papers into short overviews
• Reads the current page so you can ask questions without copy and paste
• Shows AI answers with checkable sources beside Google and Bing results
• Saves highlights and insights so you can come back to them later

Use cases

• Deciding whether a long lecture video is worth watching in full
• Pulling the main findings out of a research paper before a deeper read
• Collecting highlights from several articles while researching a topic

Getting started

Open a web page, PDF or YouTube video and launch the Liner sidebar to get a summary or ask a question. Highlight passages to save them to your collection.

Good to know

The content you are viewing is sent to the AI models Liner uses in order to answer. You can choose between several models, including ChatGPT and Claude, from the sidebar.
