What this is
What this is A ready-to-use n8n workflow that turns new Google Sheets rows (title + summary) into brand-safe images using Nano Banana (via KIE.ai), writes the image URL back to your sheet, generates a tweet text, requests human approval in Telegram, and—on approval—posts to X (Twitter) automatically. Why you need it Save time**: no more waiting for ad-hoc graphics—get on-brand visuals in seconds. Stay consistent**: one prompt style, predictable output, brand-safe negative prompts. Ship daily**: scale newsletter/blog distribution without ballooning costs or headcount. Human in the loop**: you keep creative control before anything goes live. How it works (high level) New/updated row in Google Sheets (e.g., title, blogpost_summary, status=pending). Prompt builder creates a short, safe image prompt (CI friendly). Nano Banana (KIE.ai) generates the image (PNG) → URL saved back to the sheet. A tweet (<280 chars) is generated from the row. Telegram sends image + text for approval (Approve/Reject). On Approve, the image is uploaded and the tweet is posted to X → tweet_url + status=posted saved to the sheet. Who it’s for Content & marketing teams, solo creators, agencies, and founders running lean editorial calendars. Extend it (ideas) Multi-variant** images (A/B) with auto-selection based on CTR. Brand controls**: fixed color palettes, fonts, or stylistic anchors in prompts. Auto-publish** to LinkedIn/Instagram (via Buffer/Hootsuite or native APIs). Asset storage**: push originals to S3/Drive and auto-rename by slug/date. Analytics**: log posts + clicks to a database and feed learnings back into prompts. Pricing & Advantage Nano Banana (via KIE.ai)* is typically *~$0.02–$0.04 per image** (plan-dependent). Posting to X** has no per-post cost (API plan limits may apply). Why KIE.ai vs “classic” Google API?* Lower practical unit costs for this image-gen use case, *simpler integration* (same vendor for image + video), and task/status flows that fit *n8n polling** perfectly. > Always check your KIE.ai dashboard for current pricing/limits. Quick setup (Step-by-Step) Accounts/credentials: create a KIE.ai account & API key; set up Google Sheets access; create a Telegram bot with @BotFather (copy token & get Chat ID); enable X (Twitter) API (OAuth). Import the n8n template and connect credentials (KIE.ai header: Authorization: Bearer {{ $env.KIE_API_KEY }}). Point the Google Sheets Trigger at your sheet/tab; use status=pending as the starting condition. Verify the Prompt Generator (short, brand-safe prompt + negative prompt). Test Image Gen → ensure image_url is written back to the sheet. Test Telegram approval (image + tweet text). On approve, confirm the tweet posts and tweet_url + status update in the sheet. Quick usage (Step-by-Step) Add a row in your sheet with title, blogpost_summary, (status=pending). Wait for the bot: you’ll get image + tweet text in Telegram. Approve to post to X, or Reject/Regenerate to try a new style. Find tweet_url and status updated in your sheet. Questions? Email: suliemansaid.business@gmail.com.
