Everything Claras does with a video

Which one do you need? A short guide

Every feature here works from one thing: the transcript of the video. Claras gets it once, from the captions or by transcribing the audio, and builds the summary, the chapters, the chat and the exports from that text. So the useful question is what you want to do with the video in front of you.

You want to know what a video says

Start with AI summaries. A short opening tells you what the video covers and who it is for, the takeaways give you the main points, and a summary of each section follows in order. If you then want to watch part of it, AI chapters list the main topics with their start times, and a click moves the player there.

You have a question about it

Ask AI answers from what was said, usually with a time you can check. It is best at finding where something is discussed, or what one person said about one thing. For the big picture, read the summary first: it is built from the whole transcript, while each answer reads only the parts that match your question.

You need the words themselves

The transcripts page covers the Chrome extension, which copies or downloads a YouTube transcript from a panel beside the video, without running a summary first. The web app shows the same transcript with lines you can click to jump, and adds .srt subtitles.

You have a pile of videos

Bulk Summaries takes a public playlist or a YouTube search page and writes one combined summary or one per video, then lets you ask questions across all of them. It is built for breadth. The more videos you pick, the less of each it reads, so pick fewer when depth matters.

The video isn't in your language

Languages explains how Claras writes summaries, chapters and replies in any of 15 languages, whatever the video is in, and why the transcript itself is never translated.

It isn't on YouTube

The web app also takes Instagram and TikTok links and your own video and audio files. See Instagram videos, TikTok videos and your own recordings for what changes there, such as length limits and transcription hours.

You want to take it somewhere else

Every summary and transcript can be copied or downloaded as text. Send to AI copies it and opens a new chat in Claude, ChatGPT, Gemini, Gemini Notebook or Perplexity, where you paste it and carry on with the assistant you already use.

Web app or Chrome extension?

Both use the same account and plan. The extension lives on YouTube: a Summarize button under each video, chapter markers on the progress bar, transcript copy without a summary, PDF downloads, and your own AI key on a paid plan. The web app takes every kind of source and has Bulk Summaries, .srt subtitles, and a History of your last 50 videos and runs.

What every feature has in common

• You need a free account from the first video, with no card.
• YouTube Shorts and live links don't work yet.
• Accuracy follows the transcript. Automatic captions mishear names and terms, and Claras knows what was said, not what was shown on screen.
• The free plan includes 3 videos a month and one Bulk Summaries run of up to 20 videos. Pro covers 50 videos a day, and Unlimited has no cap. Prices are on the pricing page.

A good first run

Pick a long video you've been putting off, 20 minutes or more. Read the opening, scan the takeaways, then open the Contents tab and click the chapter that caught your eye. Ask one question in Ask AI, using the speaker's own words. That single video shows you most of what Claras does, and on the free plan it uses one of your 3.
