1. **Add NewsAPI and GNews API Keys**
    - Register for accounts on [NewsAPI.org](https://newsapi.org/) and [GNews](https://gnews.io/) to obtain your API keys.
    - Input your NewsAPI key directly into the `Fetch NewsAPI articles` node.
    - Input your GNews API key into the `Fetch GNews articles` node.
2. **Set up your Telegram Bot**
    - Create a Telegram Bot via [BotFather](https://core.telegram.org/bots#6-botfather) and copy the generated Bot Token.
    - In n8n, create Telegram Bot credentials using this token.
    - In the `Send summary to Telegram` node, enter the chat ID of your target user, group, or channel to receive the messages.
3. **Configure OpenAI Credentials**
    - In n8n, create a new credential using your OpenAI API key.
    - Assign this credential to the `GPT-4.1 Model` node (or equivalent OpenAI/AI nodes).

After completing these steps, your workflow is fully configured to fetch, summarize, and deliver daily AI news to your selected Telegram chat automatically.

### How to customize this workflow

- **Change the topic:** Update the keywords in the NewsAPI and GNews nodes for other subjects (e.g., “blockchain”, “quantum computing”).
- **Adjust delivery time:** Modify the scheduled trigger to your preferred hour.
- **Tweak summary style or language:** Refine the prompt in the AI summarizer node for different tones or translate into other languages as needed."
