n8n AI Telegram Channel Publisher — Image, Video, Music Album, News

Turn a Telegram channel into a daily AI publisher without writing a custom bot. Once a day the workflow picks a format (image, video, song playlist, or news-style post), invents a topic that was not used recently, writes the caption, generates media through your LLM/media API, and sends it to the channel. Songs go out as one Telegram album (sendMediaGroup), not as separate messages. Built with stock n8n nodes (including LangChain). No extra community package. Works on n8n Cloud and self-hosted. You bring your own API keys and model IDs — OpenRouter is an example, not a lock-in. Any OpenAI-compatible host and any image, video, audio, or vision model your key can call will work. What it solves: no more “what do we post today?”, no stitching copy + image + video + music in separate tools, and no Cloud-breaking require('https') hacks for audio albums. What you get: a daily schedule (default 10:00), last 60 topics stored inside the workflow (no extra database), theme/audience/language/tone in Content Preferences, a vision pass that rewrites the caption from the real photo or video, and optional Telegraph pages with the generation prompt. Telegram only. Not WhatsApp, Discord, or an inbound chatbot. You need n8n, a Telegram bot that is admin in the channel, a Chat ID, and a media/LLM API key.
