Every morning the Schedule Trigger starts the workflow.\n2. The **Settings** node holds your videos (YouTube links or IDs, Shorts included) and an optional word filter, for example `?` to see only questions.\n3. The **YouTube Comments Scraper** Actor on Apify (`plainrows/youtube-comments-scraper`) runs with **Only new comments** on: it remembers the comments it already delivered, so each run returns only comments it has not seen before.\n4. A Code node keeps the comments that match your filter, groups them by video, sorts them by likes and builds one message with text, likes, replies and date.\n5. The message is posted to Slack. No new comment, no message.\n\n### Requirements\n- An Apify account (free plan available) and its API token.\n- A Slack workspace and the Slack credential in n8n.\n- The Apify node is the verified community node `@apify/n8n-nodes-apify` (available on n8n Cloud; on self-hosted n8n install it from Settings > Community nodes).\n\n### How to customize\n- Edit `videos` (one per line), `filter` and `monitorName` in **Settings**. Leave `filter` empty to get every new comment; use a new `monitorName` to start a fresh history.\n- Raise `maxCommentsPerVideo` in the Apify node for busy videos (up to 700 top and recent comments per video).\n- Replace Slack with Gmail, Microsoft Teams or Google Sheets, or send the text to an LLM node for a daily summary.\n\nComment authors are not collected. Each check pays a small fee per block of 20 comments requested plus a price per new comment.", "height": 760, "width": 520 }, "id": "bbf4836e-54aa-5177-8f3d-d5c1b9cc384d", "name": "Description", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -660, -340 ] }, { "parameters": { "content": "### Setup\n1. Put your videos in `videos` (one per line: YouTube link or video ID) and, if you want, a word in `filter` in **Settings**.\n2.
