Key features

• 🤖 AI-powered summaries (OpenAI/Azure OpenAI) Generate a concise TLDR and a detailed markdown summary from transcripts when available, or fall back to title/description. Ideal for “TLDR for YouTube videos” and a practical YouTube notes generator.

• 📝 Transcript extraction with timestamps Automatically fetches subtitles/auto-captions when available and returns a transcript with start/duration for each segment. Great for a YouTube transcript summarizer or YouTube video key points extractor workflow.

• 📊 Rich metadata via resilient extraction Collects views, likes, comments, duration, tags, thumbnails, channel info, language, category, and engagement_rate. A robust foundation for analytics and a YouTube video summarization API pipeline.

• 🛡️ Smart proxy fallback & retries Starts DIRECT, optionally uses your user proxy, and auto-falls back to RESIDENTIAL if blocked. Built-in exponential backoff and multiple extraction strategies improve stability at scale.

• 🚀 Batch-friendly processing Paste multiple video URLs and the actor processes them one by one, streaming results as they’re ready — perfect to summarize YouTube videos with AI at scale.

• 🔧 Developer-ready on Apify Access results via the Apify API, export as JSON/CSV/Excel, and integrate with your workflows. Works well with automation platforms in broader pipelines.

• ⏱️ Sensible limits for fast turnaround AI summaries are generated for videos up to 1 hour (<= 3,600 seconds). Longer videos are extracted with metadata and surface a clear error for summarization.

• ⚙️ Clean, consistent output schema Every item contains a status field ("ok" or "error"), with error details when applicable — making this a reliable YouTube video summary tool online for programmatic use.

How to use 🎬 YouTube Video Summarizer — AI-Powered Summaries — step by step

1. Sign in to Apify
   Create or log in to your Apify account.

2. Open the actor
   Find “youtube-video-summarizer” in your workspace or the Apify Store.

3. Add your input URLs
   Paste one or more full YouTube video URLs in urls (accepts https://www.youtube.com/watch?v=... or https://youtu.be/...).

4. (Optional) Configure a proxy
   Set proxyConfiguration to use Apify Proxy. The actor starts DIRECT and automatically falls back to RESIDENTIAL if blocked, but you can prioritize a specific group.

5. Adjust retry behavior
   Use maxRetries (1–10, default 3) to control resilience to transient failures (timeouts, temporary blocks).

6. Enable AI summaries
   Set environment variables for OpenAI or Azure OpenAI. Summaries require OPENAI_API_KEY or the Azure variables (AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT, AZURE_OPENAI_API_VERSION).

7. Run the actor
   Start the run. Results stream live to the dataset — one item per URL — making it a practical AI video summary generator for YouTube.

8. Export your data
   From the run’s Dataset tab, export in JSON, CSV, or Excel. You can also pull results programmatically via the Apify API.

Pro Tip: Automate downstream processing by reading the dataset with the Apify API or webhooks and sending summaries into your CMS, search index, or analytics stack. Ideal for building a podcast and YouTube summarizer workflow.

FAQ

Do I need an API key for AI summaries?

Yes. Set OPENAI_API_KEY to use OpenAI, or configure Azure OpenAI via AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT, and AZURE_OPENAI_API_VERSION. Without these, the actor can still extract metadata and transcripts but will return a status="error" for the summarization step.

Does it work for long videos?

Summarization is supported for videos up to 1 hour (<= 3,600 seconds). Longer videos will still have metadata extraction attempted, but the actor will report an error for the summarization step: “Video exceeds max length (1 hour).”

Can it process multiple links at once?

Yes. Provide multiple items in urls and the actor will process them sequentially, streaming one result per URL into the dataset. This is ideal to summarize YouTube videos with AI at scale.

Does it support playlists or channels?

Provide direct video URLs. The actor is optimized for single video links and generates one dataset item per video URL.

What happens if YouTube blocks my requests?

The actor starts DIRECT, then uses your user proxy if configured, and automatically falls back to a RESIDENTIAL proxy when blocked. It also implements retries with exponential backoff to handle transient network issues.

What data formats can I export?

From the Apify dataset, you can export results to JSON, CSV, or Excel. You can also fetch data via the Apify API for integration into pipelines.

Does it require login or cookies?

No. This tool does not require login. It extracts publicly available video information and captions when accessible.

Will it generate chapters or a YouTube summary Chrome extension UI?

No. This actor focuses on generating concise and long-form summaries, plus transcripts and metadata. It does not create chapters or ship as a browser extension UI.
