A podcast summarizer for episodes on YouTube and audio files
Claras is a podcast summarizer for episodes published on YouTube and for audio files you upload. You get chapters, the key takeaways, a transcript you can search and answers to your questions, each one easy to check against the episode.
Three hours of conversation, and you wanted twenty minutes of it
Long interview shows are good company on a walk. They're hard to use afterwards. The guest named a book somewhere in the second hour, the part about pricing was "around the middle", and the episode player gives you a progress bar and nothing else.
Plenty of shows now publish every full episode on YouTube, and many others offer each episode as an audio file you can save. Claras works with both. It reads the episode, so you can see what's in it, decide whether to listen, and jump to the parts you came for.
It won't replace listening to the shows you love. It helps with the episodes you'd otherwise skip, and with finding a moment again later. If you want to know how to summarize a podcast step by step, there's a worked example further down.
See what's in an episode before you press play
Paste the YouTube link of an episode, or upload the audio file. You get a short opening, 4 to 8 key takeaways, a section for each part of the conversation and titled chapters.
- Click a chapter to play the episode from that moment
- Chapters that look like an ad read are marked
- Search the transcript for a name, a book or a phrase
Ask about the part you care about
Ask AI answers from the episode's transcript and usually gives the time it was said, so you can hear it in the speaker's own words.
- Ask "What books does the guest recommend?"
- Get through a show's episode playlist with Bulk Summaries
- Upload MP3 or M4A episodes with file uploads
- Send to AI to keep working in Claude or ChatGPT
Three ways people use an AI podcast summarizer
These are scenarios, not stories from real listeners.
Decide whether a new episode is worth your evening
Say a show you follow puts out a two-hour episode with a guest you've never heard of. Paste the YouTube link into Claras. If the episode has captions, which many YouTube uploads do, Claras reads them and none of your transcription hours are used.
Read the key takeaways first. If two or three of them are new to you, look down the chapters and pick the stretches you want. Click a chapter and the YouTube player starts there. If nothing grabs you, you've spent a few minutes instead of two hours.
Catch up on a backlog from one show
Say you fell behind on a weekly show and 15 episodes are waiting. Many podcasts on YouTube keep their episodes in a public playlist. Paste the playlist link into Bulk Summaries, tick the episodes and choose one summary per video.
Be aware of depth. A per-video summary in a batch reads the first 40,000 characters of each transcript, so a long episode is covered only in its first part. A combined summary shares a fixed budget across the whole batch and reads even less of each one. Use the batch to choose, then run the episodes you care about on their own, where the summary is built from the whole transcript.
Summarize a podcast that isn't on YouTube
Many shows publish each episode as an MP3 on their own website or feed. If you can save that file, open the Audio tab in the web app and drop it in. Claras transcribes it with AI, then writes the same summary, chapters and transcript as for a YouTube episode.
Uploads use transcription hours, counted by the length of the audio, so a 90-minute episode uses an hour and a half. Click a chapter and the file plays from that moment, straight from your own disk.
How to summarize a podcast episode, step by step
Say you have a 2 hour 30 minute interview episode on YouTube, with captions, and you want the main points plus the one story the guest told about their first company.
- Paste the link and choose your language. Pick the language you want to read in, one of 15. The summary and answers come back in it, whatever language the episode is in.
- Let it read the whole episode. Claras reads the transcript in 20-minute stretches and summarizes each one, then writes the overview from those parts. The last hour gets the same attention as the first, which matters on long shows that warm up slowly.
- Read the takeaways, then the chapters. On a long episode the chapters are broader than on a short video, with a new one at least every five minutes or so. Each has a title and a one-line description.
- Find the story. Search the transcript for a word the guest would have said, like "company" or "founded". Search matches part of a word, so "found" finds both. In the web app, click the line to hear it.
- Ask in the guest's words. Ask AI picks the five passages that share the most words with your question. "What happened with the first company?" works better than "Tell me about early failures" if the guest never said "failure".
- Check before you repeat it. Timestamps in answers are plain text, so go to that time in the player and listen. A summary can merge two stories or drop a detail.
- Keep what you need. Copy the summary into your notes, download the transcript as a text file, or use Send to AI to ask Claude or ChatGPT for something Claras doesn't do, like a reading list.
What doesn't work, and what to check
Spotify and Apple Podcasts links
Claras can't read a Spotify or Apple Podcasts link, or a podcast's RSS feed. If you paste one, the app says the link doesn't look like a YouTube, Instagram or TikTok link. Look for the same episode on YouTube, or save the episode's audio file and upload it.
Other links that fail
- Links in the /shorts/ or /live/ form are turned away. Use the episode's normal watch link.
- A YouTube episode with no captions needs AI transcription: up to 30 minutes on the free plan and up to 3 hours on a paid plan.
Who said what
The transcript has no speaker labels. On a show with two hosts and a guest, the lines run together. "What did the guest say about hiring?" works when the wording makes it clear, but check who is talking by listening at that time.
Audio files
- Uploads go through the web app, up to 6 hours per file. The Chrome extension works on YouTube only.
- Keep the tab open while it transcribes. If it closes, choose the same file again and it picks up where it stopped.
- Music beds, crosstalk and laughter over speech can cause mistakes.
AI can be wrong
Captions and AI transcription mishear names and numbers. The summary is the AI's reading of the transcript, and it can misstate a point or blend two speakers' views. Before you quote an episode, hear the line yourself.
What people say about long videos
"I use it to skim long videos and go straight to the parts that interest me. The summaries are clear and well organized. It saves me hours every week. Highly recommended."
Etienne Douaze, Chrome Web Store
"In 30 days I've analyzed more than 100 videos, over 44 hours of content summarised."
Rodrigo Ambros, Software Architect
Neither of them says what they watch, so we won't call them podcast listeners. They're the reviews closest to this job.
What it costs to summarize podcasts
The free plan gives you 3 videos a month and 1 hour of transcription for uploads, with no card. YouTube episodes with captions don't use any hours, however long they are, so three long episodes a month cost nothing.
As a rough guide, Pro suits a listener who follows a few shows on YouTube, with 50 videos a day. If your episodes come as audio files, hours matter more: a weekly two-hour show is about 8 to 10 hours a month, which is about what Pro's 10 hours cover. Unlimited, with 100 hours, suits someone uploading several shows.
Both paid plans start with 14 days free, and first payments come with a 30-day money-back guarantee. See what each plan costs, or go back to all solutions.
Questions about summarizing podcasts
Can I paste a Spotify or Apple Podcasts link?
No. Claras doesn't read Spotify or Apple Podcasts links, or RSS feeds. Look for the episode on YouTube and paste that link, or save the episode as an audio file and upload it.
How do I summarize a podcast that's only available as audio?
Save the episode as a file, for example the MP3 many shows offer on their website. Open the Audio tab in the web app and drop it in. MP3, M4A, WAV, FLAC, AAC, OGG and Opus all work, up to 6 hours per file. Uploads use your transcription hours.
Is there a free podcast summarizer here?
Yes. The free plan includes 3 videos a month and 1 hour of transcription for uploads, with no card. A YouTube episode with captions uses no hours, so a long episode fits.
What's the best AI podcast summarizer?
It depends on where your podcasts live. If the shows you follow are on YouTube, or you can save episodes as files, Claras works well and adds chapters and a chat. If you only listen in Spotify or Apple Podcasts and want to paste those links, Claras can't help.
Does the summary say who said what?
No. The transcript has no speaker labels, so hosts and guests run together. Listen at the timestamp before you attribute a quote to anyone.
How long can an episode be?
A YouTube episode with captions uses no hours and has no 3-hour cap, and the summary covers the whole thing, even at several hours. A YouTube episode without captions can run up to 3 hours on a paid plan. An uploaded file can run up to 6 hours.
Can I get podcast summaries for a whole show?
Yes, if the show keeps its episodes in a public YouTube playlist. Bulk Summaries lists up to 50 videos from a playlist. In a batch, each long episode is read only in part, so run the important ones on their own as well. Channel pages aren't accepted.
Does it work for podcasts in other languages?
Yes. The summary and Ask AI answers come back in the language you pick, one of 15. The transcript isn't translated.
