Detect YouTube Trending Topics & Send Telegram Alerts (n8n)

Detect YouTube Trending Topics and Get Instant Telegram Alerts (n8n)

This n8n workflow scans YouTube for your configured topics using the RecentReborn API, detects meaningful spikes and breakout phrases, and sends a ranked digest to your Telegram chat—typically on an hourly schedule.

What this workflow does

• Runs hourly (or manually) to load your topic and threshold settings.
• For each topic, it builds a YouTube search plan, optionally including Shorts, while enforcing a per-run credit budget and page caps.
• Queries the RecentReborn YouTube search API page-by-page with a short delay, stopping when it hits a last-seen watermark, configured limits, or a low daily quota condition.
• Tracks posting volume changes: aggregates new results, compares the current posting rate to a median baseline from recent runs, and classifies topics as learning, rising, spiking, cooling, or normal.
• Detects newcomers and extracts breakout words and phrases from video titles, applying stopwords and cooldowns to avoid repeated alerts.
• Sends a single Telegram digest (splitting into multiple messages if needed) and posts only when there’s something notable to report (or always on manual runs).

Use cases

• Monitor competitive markets and spot YouTube breakout trends early.
• Run lightweight content research for SaaS product teams and creators.
• Track tech keywords and get alerts when interest shifts from rising to spiking.
