English Vocabulary Bot for Telegram with Gemini & Random Word API

📄 What this workflow does Every 3 hours, the workflow fetches 3 random English words, asks Gemini to generate a short Vietnamese vocabulary digest (word, Vietnamese meaning, and an example sentence), and sends it to a Telegram chat. Perfect for steady, low-effort vocab exposure in groups.

👤 Who is this for English learners who want a gentle, automated learning cadence. Teachers/tutors who share daily vocab in Telegram groups. Community admins who want lightweight, useful content for members. Anyone who prefers bite-sized language learning on autopilot.

✅ Requirements Gemini API access (configured in n8n). Telegram Bot token + chat ID (the chat you want to receive messages). Internet access to Random Word API (no API key required). n8n instance with outbound HTTPS access.

⚙️ How to set up Add your Gemini credentials in n8n (the Google Gemini/PaLM node). Add your Telegram credentials and set the chatId in the “Send a text message” node. (Optional) Adjust the schedule interval (default: every 3 hours). (Optional) Change the number of words by updating the HTTP Request URL param words=3. (Optional) Edit the Gemini prompt language/content to fit your style (currently Vietnamese output). Run once to test; confirm the message arrives in Telegram.

🔁 How it works Schedule Trigger → runs every 3 hours. HTTP Request → calls random-word-api to get 3 words. Edit Fields (Set) → wraps the API response under word. Aggregate → prepares the word field for the LLM. Message a model (Gemini) → creates a Vietnamese digest: English word, Vietnamese meaning, and example sentence for each word. Send a text message (Telegram) → posts the digest to your specified chat.
