• 🧠 AI-powered summaries Generates a concise overview and a detailed markdown long summary using OpenAI or Azure OpenAI, acting as a YouTube transcript summarizer and YouTube video key points extractor.

• 🕒 Timestamped transcript handling Builds timestamped YouTube summary inputs from caption segments (start/duration/text) when available for higher-quality results.

• 🔄 Retry & proxy fallback Automatic retries with backoff and intelligent proxy switching: starts DIRECT, uses your proxy if provided, and falls back to RESIDENTIAL if blocked.

• 📦 Structured, ready-to-use output Clean JSON with consistent status and error fields, ideal for analytics, pipelines, and YouTube to article summary transformations.

• 👩‍💻 Developer friendly Run on the Apify platform programmatically, stream results to the dataset, and integrate with your stack for automated “YouTube URL to summary” workflows.

• 🚫 No login required Works without cookies or sessions, making it simpler and more reliable than a YouTube video summarizer chrome extension.

How to use Youtube Video Summarizer - step by step

1. Create or log in to your Apify account.
2. Open the Youtube Video Summarizer actor on the Apify platform.
3. Paste one or more YouTube video URLs into the urls field (accepts full https://youtube.com/watch?v=… or https://youtu.be/… links).
4. (Optional) Configure proxyConfiguration to use Apify Proxy (recommended for scale). If left empty, the actor starts DIRECT and can auto-fallback to RESIDENTIAL if blocked.
5. (Optional) Set maxRetries (default 3) to increase resilience against transient errors.
6. Provide your OPENAI_API_KEY or Azure OpenAI variables (AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT, AZURE_OPENAI_API_VERSION) in the actor’s environment to enable AI summaries.
7. Click Start to run. The actor will extract metadata, attempt to load captions, and generate summaries.
8. Watch items stream into the Dataset. Each URL produces a structured record with status "ok" or "error".
9. Export results from the Dataset to JSON or CSV for analysis, reporting, or integration.

Pro tip: Use the Apify API to trigger runs and pull dataset records into your data warehouse or CRM to auto summarize YouTube video libraries at scale.

FAQ

Do I need to log in to summarize YouTube videos?

No. The actor works without login or cookies. It uses public pages and captions to extract metadata and generate summaries.

Can I use my own OpenAI or Azure OpenAI keys?

Yes. Set OPENAI_API_KEY for OpenAI, or AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT, and AZURE_OPENAI_API_VERSION for Azure OpenAI in the actor’s environment. With credentials configured, the actor functions as an AI YouTube summarizer that outputs both concise and long-form summaries.

How long can the videos be?

The actor summarizes videos up to 1 hour. This keeps processing fast and predictable while still covering most tutorials and lectures.

What if a video has no captions?

If no transcript is available, the actor falls back to the title and description to generate a summary. In that case, summary_source will reflect "title_description" or "basic."

How does it handle blocks or timeouts?

It implements retries with exponential backoff and proxy fallback: it starts DIRECT, uses your proxy if configured, and automatically switches to RESIDENTIAL if blocked. This makes it reliable for auto summarize YouTube video workflows at scale.

What data does the actor return?

Each item includes status and error fields, video metadata (title, views, likes, tags, thumbnails, channel info), transcript segments when available, and AI-generated summary fields (summary, long_summary, summary_source). It’s ideal for YouTube video notes generation and timestamped summaries.

Can I integrate it into automated pipelines?

Yes. Run the actor via the Apify API and pull the dataset JSON into your systems. Many teams use it for YouTube to article summary conversion, weekly digests, or enrichment pipelines.
