n8n Instagram Reels to Content Strategy: Telegram + OpenAI

Turn an Instagram Reel link into a ready-to-post content strategy—automatically

Send an Instagram Reel URL to your Telegram bot and this n8n workflow extracts the transcript, analyzes it with OpenAI (gpt-4o-mini), then returns a structured content strategy (hooks, audience, why it works, adjacent ideas, and an original script). Results are cached for 24 hours to avoid repeat processing costs.

What this workflow does

• Telegram trigger: When your bot receives a new message, it handles /start and /help with instant responses.
• Instagram URL validation: The workflow extracts the first Instagram URL from your message and rejects unsupported formats (e.g., profiles or Stories) before any paid processing begins.
• 24-hour cache check: It looks for a recent analysis in n8n static workflow storage. If found, it formats and returns the cached response immediately.
• Apify transcript + metadata: If no cache exists, it runs the Apify Actor lance_api/instagram-video-ai-transcript-scraper-api to fetch Reel metadata and transcribe the audio (with a brief wait and one re-check if still in progress).
• Transcript validation: If the transcript is missing/too short, private, login-blocked, or otherwise unusable, it replies in Telegram with a clear error.
• OpenAI structured strategy: It sends the transcript + metadata to OpenAI (gpt-4o-mini) to generate a structured breakdown and an original script.
• Telegram-safe delivery: The output is chunked to stay under Telegram’s 4096-character limit, then cached for 24 hours on success.

Use cases

• Repurpose a top-performing Reel by generating a content strategy and next-script quickly.
• Build a Telegram-driven “Reel-to-Plan” system for founders and SaaS marketing teams.
• Validate and automate Reel analysis inside an n8n automation workflow without re-scraping repeated links.
