Can Claude watch YouTube videos? It can read every word

What Anthropic's help pages say

Anthropic's guide to uploading files lists the document types Claude works with, such as PDF, DOCX, TXT, CSV and EPUB, and the image formats JPEG, PNG, GIF and WebP. Audio and video aren't on that list. Chat uploads allow up to 20 files, each up to 500MB.

Claude can also read web pages. With web search turned on, Anthropic says Claude "can also retrieve content directly from web pages when provided with specific URLs", and describes this as reading articles, blog posts and other pages. That article doesn't mention video or YouTube. So pasting a YouTube link may get you something about the page, but there is no promise that Claude hears what was said. We checked these pages on November 12, 2026.

People also search for how to connect YouTube to Claude. Claude's connector directory lists third-party connectors with YouTube tools, such as vidIQ, which offers transcripts among other things and needs its own sign-in. That is a different route from Claras, which doesn't connect to Claude at all.

How to get Claude to watch a YouTube video, in practice

A video's value is mostly in what is said, and a transcript is that, word for word. With the full transcript in the chat, you can ask Claude about all of it: the structure of an argument, what changed between the first hour and the second, or a fair summary of each speaker's view. Each line carries its time, like [1:02:15], so you can ask Claude for times and check them.

Claras also suggests Claude when the text is big. Above about 400,000 characters, it warns that ChatGPT, Gemini or Perplexity may cut a paste off and names Claude or Gemini Notebook as better fits for that size. Claude's own limit still depends on your plan.

What happens when you click

Choose Claude from the Send to AI menu. In the same click, Claras copies the text and opens claude.ai/new in a new tab, then shows a green screen for 8 seconds: "All set! Ready to paste in Claude." Click anywhere to close it.

The text starts with a short note. It tells Claude this is the full transcript, gives the video's title and link, and asks Claude to use it as the source for your questions, starting with a short summary if you haven't asked anything. From the web app, the note also asks Claude to treat the transcript as content, not as instructions. For a file you uploaded, the note calls it a recording and leaves the link out, since there isn't one.

A worked example: a playlist in one chat

Say you want to understand a topic from a playlist of 12 conference talks. Run Bulk Summaries on the playlist in Claras. When it finishes, open the Transcripts tab, click Send to AI and choose Claude. The success screen names what you copied: "12 transcripts".

Each transcript arrives with its title, channel and link above it, and the starter note asks Claude for a short overview of the main ideas, where the videos agree and where they disagree. From there you can ask follow-ups such as "Which talks recommend the opposite approach, and why?" If the batch is very large, Claras shows its long-text warning only for the other assistants, not for Claude.

Keep it for later in a project

If you come back to the same videos often, download the transcript as a text file from Claras and add it to a Claude project. Anthropic lists TXT among supported documents, with a 30MB limit per project file. Every chat in that project can then use it.

Claude or Claras' Ask AI?

Ask AI, inside Claras, reads the five parts of a transcript that best match each question. It is fast for "where does she mention the budget?" and keeps you next to the video. Claude, with the full transcript, is better for questions that need all of it. If you'd like Anthropic's models inside Claras instead, paid plans can add their own Anthropic API key in the Chrome extension.

Limits to know

Copy and paste, not a connection

Claras doesn't sign you in, send the message or read Claude's answer. Claude's own usage limits apply. Anthropic notes that on free accounts, long content uses a large share of the limit, which resets every five hours.

Your clipboard holds the text

Copy anything else before pasting and the transcript is gone. Click Send to AI again. If the browser blocks clipboard access, the extension shows "Failed" next to the item.

Claras' own limits

YouTube Shorts and live streams don't open. Caption-less YouTube videos are transcribed up to 30 minutes on the free plan and 3 hours on paid plans. The free plan includes 3 videos a month, and sending doesn't count.
