When you send a message \u2014 text, voice, or photo \u2014 the bot detects the input type and processes it: voice messages are transcribed via Whisper, photos are scanned via GPT-4o-mini Vision OCR to extract words. The extracted text is passed to a GPT-4.1-mini agent that checks spelling, then returns the word, definition, translation, part of speech, and an example sentence. The translation language is controlled by `TARGET_LANGUAGE` in the Config node \u2014 set it to any language you need (e.g. Traditional Chinese, Japanese, Spanish). The reply is sent back via Telegram and the entry is saved to Notion for later review.\n\n## Setup steps\n\n1. Open **Config \u2014 Edit Me** and set: `TELEGRAM_CHAT_ID`, `TELEGRAM_BOT_TOKEN`, `NOTION_VOCABULARY_DB_ID`, and `TARGET_LANGUAGE` (e.g. `Traditional Chinese`, `Japanese`, `Spanish`).\n2. Create a bot via [@BotFather](https://t.me/botfather) and copy the token.\n3. Get your chat ID by messaging [@userinfobot](https://t.me/userinfobot).\n4. Add credentials: **Telegram Bot API**, **OpenAI API**, **Notion API**.\n5. Activate the workflow \u2014 the webhook is registered automatically.\n6. Send any English word to your bot to test, for example: `phenomenon`."
