Auto-comment on Reddit posts with AI brand mentions & Baserow tracking

This workflow finds fresh Reddit posts that match your keywords, decides if they’re actually relevant to your brand, writes a short human-style reply using AI, posts it, and logs everything to Baserow. 💡Perfect for - Lead gen without spam: drop helpful replies where your audience hangs out. - Get discovered by AI surfaces (AI Overviews / SGE, AISEO/GSEO) via high-quality brand mentions. - Customer support in the wild: answer troubleshooting threads fast. - Community presence: steady, non-salesy contributions in niche subreddits. 🧠 What it does - Searches Reddit for your keyword query on a schedule (e.g., every 30 min) - Checks Baserow first so you don’t reply twice to the same post - Uses an AI prompt tuned for short, no-fluff, subreddit-friendly comments - Softly mentions your brand only when it’s clearly relevant - Posts the comment via Reddit’s API - Saves postid, commentid, reply, permalink, status to Baserow - Processes posts one-by-one with an optional short wait to be nice to Reddit ⚡ Requirements - Reddit developer API - Baserow account, table, and API token - AI provider API (OpenAI / Anthropic / Gemini) ⚙️ Setup Instructions 1. Create Baserow table Fields (user-field names exactly): postid (unique), permalink, subreddit, title, createdutc, reply (long text), replied (boolean), createdon (datetime). 2. Add credentials in n8n Reddit OAuth2 (scopes: read, submit, identity) and set a proper User-Agent string (Reddit requires it). LLM: Google Gemini and/or Anthropic (both can be added; one can be fallback in the AI Agent). Baserow: API token. 3. Set the Schedule Trigger (Cron) Start hourly (or every 2–3h). Pacing is mainly enforced by the Wait nodes. 4. Update “Check duplicate row” (HTTP Request) URL: Header: Authorization: Token YOURBASEROWTOKEN (Use your own Baserow domain if self-hosted.) 5. Configure “Filter Replied Posts” Ensure it skips items where your Baserow record shows replied === true (so you don’t comment twice). 6. Configure “Fetch Posts from Reddit” Set your keyword/search query (and time/sort). Keep User-Agent header present. 7. Configure “Write Reddit Comment (AI)” Update your brand name (and optional link). Edit the prompt/tone to your voice; ensure it outputs a short reply field (≤80 words, helpful, non-salesy). 8. Configure “Post Reddit Comment” (HTTP Request) Endpoint: POST Body: thingid: "t3{{$json.postid}}", text: "{{$json.reply}}" Uses your Reddit OAuth credential and User-Agent header. Update useragent value in header by your username n8n:reddit-autoreply:1.0 (by /u/{reddit-username}) 10. Store Comment Data on Baserow (HTTP Request) POST Header: Authorization: Token YOURBASEROWTOKEN Map: postid, permalink, subreddit, title, createdutc, reply, replied, createdon={{$now}}. 11. Keep default pacing Leave Wait 5m (cool-off) and Wait 6h (global pace) → \4 comments/day. Reduce waits gradually as account health allows. 12. Test & enable Run once manually, verify a Baserow row and one test comment, then enable the schedule. 🤝 Need a hand? I’m happy to help you get this running smoothly—or tailor it to your brand.
