An OpenAI agent writes them from the brand rules you keep in a Google Doc, and PostWire publishes them after you approve.\n\n### How it works\n1. **New topic in Telegram** takes any text message sent to your bot (commands are skipped).\n2. **Get the brand rules** reads your Google Doc: voice, audience, words to avoid, examples.\n3. **Write the posts with an AI agent** follows those rules, searches Google with SerpApi when it needs fresh facts, and returns one post per network.\n4. **Send the drafts** shows them in your Telegram chat and **Ask for approval in Telegram** waits for Approve or Decline.\n5. On Approve, **Publish with PostWire** posts each network with its own text. Google Sheets logs the result, and the bot replies with the links or the exact fix for each network that refused.\n\n### Setup\n1. Create a free account at postwire.io, connect your networks and copy your API key. In n8n add a **Header Auth** credential (name `Authorization`, value `Bearer pw_live_…`) and select it in **Publish with PostWire**.\n2. Write your brand rules in a Google Doc and paste its URL in **Get the brand rules**.\n3. Add an OpenAI credential to the chat model and a SerpApi key to the search tool (the free plan is enough).\n4. Create a bot with @BotFather and select its credential in the trigger and the five Telegram nodes.\n5. Create a sheet with the columns date, topic, status, links and note, and pick it in both Sheets nodes.\n\n### Customize\nEdit the networks in Read the posts, or swap the chat model."
