Code Integration
The Serverless Function node lets you run your own code as a step in a workflow. It is the place for custom logic that no off-the-shelf node covers: reshaping data, doing calculations, branching on complex conditions, or transforming one node's output into the format the next node expects. You write the function, name its inputs, and the workflow runs it on demand.

Faceless Videos Generation Workflow
## Full Description Turn any video idea into a published short-form video in minutes, completely automated and fully faceless. This workflow manages the entire pipeline end-to-end: it pulls ideas from a Google Sheet, generates a cinematic first-frame image and an 8-second vertical video using AI, allows you to approve the output, and then publishes it across TikTok, Instagram Reels, and YouTube Shorts simultaneously. It can run automatically every day at 7 AM or be triggered manually from a built-in dashboard. [@youtube](https://www.youtube.com/watch?v=XBjd7tV4QO8) --- ## What It Does - Reads queued video ideas from your Google Sheet (topic + scene environment) - Generates a scene caption, Veo prompt, and social copy using GPT-4o-mini - Creates a cinematic vertical first-frame image using Gemini - Allows approval or regeneration of the image before video creation - Animates the approved image into an 8-second vertical video using Veo 3 - Writes a high-conversion caption with hook and hashtags - Publishes content to TikTok, Instagram Reels, and/or YouTube Shorts - Updates your Google Sheet with status and generated image - Logs each run and optionally sends a Slack notification --- ## Built-in Dashboard A centralized interface to manage your entire content queue: - Add or remove video ideas - View upcoming scheduled content - Trigger manual runs instantly - Access and review pending approvals --- ## Who This Is For - Creators building faceless content channels with consistent posting schedules - Entrepreneurs running niche content pages (POV, productivity, daily life, etc.) - Marketers who need daily short-form content without a production team - Anyone who wants to publish regularly without using a video editor --- ## Setup Setup takes approximately 2 minutes: 1. Connect Google Sheets (required) 2. Optionally connect: - TikTok - Instagram - YouTube - Slack The workflow automatically creates and pre-populates your spreadsheet with an example row so you can get started immediately. --- ## Nodes Used - Google Sheets - Gemini (image generation) - Veo 3 (video generation) - GPT-4o-mini (captions and copy) - TikTok - Instagram - YouTube - Slack
Twitter/X Community Monitor with AI Analysis & Auto-Reply Drafts
Monitor Twitter/X for high-quality tweets matching your search criteria, analyze them with AI, and get draft replies ready for approval — all logged to a Google Sheet. ## What it does Automatically searches Twitter/X on a schedule, uses AI to filter for quality and relevance, drafts thoughtful replies, and surfaces the best tweets in an approval feed for human review before posting. ## Pipeline 1. **Fetch Tweets** — Runs a Twitter/X search query on a configurable schedule (default: every hour) using the Twitter API. Supports full X search syntax: hashtags, from:user, "exact phrases", OR operators, and -exclusions. 2. **AI Quality Analysis** — Each tweet is analyzed by an AI agent that scores it on content quality, engagement metrics, and relevance to your monitoring criteria. Tweets are categorized (insight, news, discussion, resource, question) and assigned a priority level. 3. **Smart Filtering** — Only tweets flagged as relevant pass through. Low-quality, spam, and off-topic content is automatically filtered out and logged. 4. **Reply Drafting** — For relevant tweets, an AI agent drafts a concise, authentic reply (under 280 characters) matching your configured reply style. No promotional or spammy content. 5. **Human Approval** — Drafted replies appear in the Approval Feed where you can review the tweet, AI summary, and proposed reply. Approve to post and log, or reject to skip. 6. **Google Sheets Logging** — Approved tweets are logged to a tracking spreadsheet with author, tweet text, link, priority, category, AI summary, and the drafted reply. ## Setup [@youtube](https://youtu.be/4Bf1m2W0QVs) A one-time setup flow connects your Twitter/X account (OAuth) and Google account, then creates a dedicated tracking spreadsheet with column headers. ## Interface A custom dark-themed configuration UI lets you: - Connect your X account - Set your search query with full X search syntax - Define quality criteria for the AI analyzer - Customize the reply tone and style - Launch monitoring with one click ## Input - **Twitter/X search query** — Any valid X search syntax - **Quality criteria** — Natural language description of what makes a tweet worth reviewing - **Reply style** — Instructions for how drafted replies should sound ## Output - **Approval Feed items** — High-quality tweets with AI analysis and draft replies - **Google Sheet** — Running log of all approved tweets with metadata - **Filtered logs** — Record of skipped tweets for transparency
