How to use Youtube Video Summarizer - step by step

1. Sign in to Apify Create or log into your Apify account to access the actor.

2. Open the actor Find “youtube-video-summarizer” in your console or the Apify Store and click Try for free.

3. Add input URLs In the input form, paste one or more YouTube video URLs into the “YouTube Video URLs” list. Accepted formats include:

   • https://www.youtube.com/watch?v=VIDEO_ID
   • https://youtu.be/VIDEO_ID

4. (Optional) Configure proxy Leave proxy empty to start DIRECT. If YouTube blocks access, the actor automatically falls back to RESIDENTIAL. You can also enable Apify Proxy and choose your preferred group.

5. Start the run Click Start. The actor fetches metadata, tries to load transcripts, and generates summaries (if OpenAI/Azure OpenAI is configured).

6. Watch results stream Items are pushed to the dataset as they complete. Each video yields one record with status "ok" or "error".

7. Export your data From the dataset, export results as JSON, CSV, or Excel. Use the Apify API to integrate directly into your workflows.

Pro Tip: Set OPENAI_API_KEY or Azure OpenAI environment variables to enable AI summaries. Use webhooks or the Apify API to trigger runs from your own apps and feed results into your YouTube notes generator or analytics stack.

• If AI credentials are not configured, items return status "error" with an explanatory message.

FAQ

Do I need an API key to generate summaries?

Yes. Set OPENAI_API_KEY or Azure OpenAI environment variables to enable AI summaries. Without a valid configuration, items will return status "error" with a clear message.

Can it summarize long YouTube videos?

Yes, up to 1 hour in length. If a video exceeds 3600 seconds, the actor returns an error for that item to keep processing predictable and fast.

What happens if a video has no transcript?

The actor falls back to summarize from the title and description. If neither is usable, it returns a basic note with summary_source indicating the fallback.

Can I process multiple URLs at once?

Yes. The urls input accepts a list of YouTube links. Each URL is processed independently and pushed to the dataset as soon as it’s ready.

Is this a Chrome extension to summarize YouTube videos?

No. This is a server-side YouTube summary tool that runs on Apify. It’s an alternative to a YouTube TLDR extension — ideal for automation, bulk analysis, and API-driven workflows.

How do proxies work?

By default, the actor starts DIRECT. If YouTube rejects access, it automatically falls back to a RESIDENTIAL proxy. You can also enable Apify Proxy in the input to prefer your own group first.

What export formats are supported?

Results are stored in an Apify dataset, which you can export as JSON, CSV, or Excel. You can also fetch results programmatically via the Apify API.

Is there a free trial?

Yes. The Apify listing includes trial minutes (e.g., 120 trial minutes). After that, usage follows the actor’s subscription terms as shown on the Apify Store.
