        "content": "## 🎧 Daily RSS Digest & Podcast Generation\n\n**Convert RSS Feeds into a Podcast with Google Gemini, Kokoro TTS, and FFmpeg:** This workflow automates the creation of a daily sports podcast from your favorite news sources. It fetches articles, uses AI to write a digest and a two-person dialogue, and produces a single, merged audio file with KOKORO TTS ready for listening.\n\n## ✨ How it works:\n\n### 📰 Fetch & Filter Daily News: The workflow triggers daily, fetches articles from your chosen RSS feeds, and filters them to keep only the most recent content.\n\n### ✍️ Generate AI Digest & Script: \nUsing Google Gemini, it first creates a written summary of the day's news. A second AI agent then transforms this news into an engaging, conversational podcast script between two distinct AI speakers.\n\n### 🗣️ Generate Voices in Chunks: \nThe script is split into individual lines of dialogue. The workflow then loops through each line, calling a Text-to-Speech (TTS) API to generate a separate audio file (an MP3 chunk) for each part of the conversation.\n\n### 🎛️ Merge Audio with FFmpeg: \nAfter all the audio chunks are created and saved locally, a command-line script generates a list of all the files and uses FFmpeg to losslessly merge them into a single, seamless MP3 file. All temporary files are then deleted.\n\n### 📤 Send the Final Podcast: \nThe final, merged MP3 is read from the server and delivered directly to your Telegram chat with a dynamic, dated filename.\n\n### You can modify:\n- 📰 The RSS Feeds to any news source you want.\n- 🤖 The AI Prompts to change the tone, language, or style of the digest and podcast.\n- 🎙️ The TTS Voices used for the two speakers.\n- 📫 The Final Delivery Method (e.g., send to Discord, save to Google Drive, etc.).\n\n\nPerfect for creating a personalized, hands-free news briefing to listen to on your commute.\n\n**Inspired by:** https://n8n.io/workflows/6523-convert-newsletters-into-ai-podcasts-with-gpt-4o-mini-and-elevenlabs/"

It triggers once a day, fetches the latest articles from multiple RSS feeds, merges them, and filters the list to keep only articles published on the previous calendar day. This provides a clean, relevant dataset for the AI.\n\n### ✅   Expected Output \nA clean list of news articles, each containing a title, content, link, and a standardized date, ready to be processed by the AI.\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n### 🤖 Logic Explained:\nThe crucial step is the Filter for Yesterday node. It keeps only articles published on the previous calendar day. It does this with two conditions:\n**1. is greater than: The article's date must be after midnight at the start of yesterday.\n2. is less than: The article's date must be before the time scheduled to running.**\n\nThis ensures the AI always has a fresh, consistent set of news to work with.\n\n### ✍️ How to Customize:\n- Trigger: Change the time or frequency in the `Daily Trigger` node.\n- News Sources: Change the URLs in the Fetch... News nodes to any RSS feed you want. Add or remove feeds as needed, connecting them to the Merge News Sources node.\n"

It must sound like two well-informed people exchanging ideas, not like a text being read aloud.\n\n### Roles\n\n- **voice1**: Curious, expressive, casual, often injects humor or everyday references. Tends to ask questions, react with surprise or amusement, and bring lightness to the discussion.\n- **voice2**: Analytical, composed, insightful. Adds perspective, context, and a slightly ironic or dry sense of humor. Offers clarity without sounding robotic.\n\nUse realistic, human-like phrasing with brief interjections (`\"Right?\"`, `\"Let me stop you there\"`, `\"That's exactly it\"`). Use `<break time=\"1.5s\" />` tags occasionally to simulate natural pauses.\n\n### Structure\n\n1. **Introduction**: Set the scene naturally. Briefly introduce what the episode is about based on the content, without listing or labeling sections. Present `voice1` and `voice2` through dialogue, not narration.\n2. **Content Breakdown**: For each key idea or section from the newsletter:\n   - Paraphrase the content in spoken language.\n   - Embed the headline or theme organically in the conversation.\n   - Include personal reactions, examples, and small tangents to make it relatable.\n   - Open loops by teasing questions or ideas that will be answered later in the conversation.\n   - Maintain curiosity and variety in tone and rhythm.\n3. **Closing**: End warmly and casually, with a brief comment on what stood out or what’s coming next (no need for formal farewells).\n\n### Requirements\n\n- The script must be at least **ten thousand characters** (about 15 minutes of speech).\n- Use **commas** to separate items in a list, not periods.\n- Format the output as a single uninterrupted block of text with clear speaker tags:\n  \nvoice1: …\nvoice2: …\n\nYou will be given a newsletter input under this key:\n\n{{ $('Prepare Data for AI').item.json.allNews }}\n\nGenerate only the final dialogue script — no explanations, bullet points, or headings. Just the conversation in English.\n\n\n",

Text Digest:** The `Generate Text Digest` agent creates a written summary of the news, which is immediately sent to Telegram via the `Send Text Digest` node. This provides a quick, readable update.\n\n**2. Podcast Script:** The `Generate Podcast Script` agent takes the same news data and, following a detailed prompt, writes a long-form conversational dialogue between two distinct AI speakers `(voice1 and voice2)`. The `Create Temp Directory` node runs first to ensure the folder for saving audio files `(/tmp/dailydigest)` exists on the server.\n\n### ✍️ How to Customize:\n- AI Prompts: The core of this section is the prompts inside the `Generate Text Digest` and `Generate Podcast Script` nodes. **You can edit these extensively to change the tone, style, length, language, and format of the output.**\n- AI Model: Change the model used for generation in the corresponding `Google Gemini Chat Model` nodes.\n- Directory: If you change the temporary directory path in the Create Temp Directory node, **you must update it everywhere else in the workflow.**"

These are now ready to be saved to the server.\n\n### 🤖 Logic Explained:\nThis section is the core audio generation engine.\n\n**1. Split Script:** The `Split Script by Speaker` node takes the long dialogue from the AI and uses a regular expression to split it into an array of smaller text chunks, one for each line of dialogue.\n**2. Loop & Clean:** The workflow then loops through each chunk. The `Clean Dialogue Segment` and `Prepare Text for TTS` nodes remove any unwanted characters or speaker tags (like \"voice1:\") from the text to ensure it's clean for the TTS API.\n**3. Route & Generate:** The `Route to Correct Voice` node checks which speaker the line belongs to and sends it to the correct HttpRequest node. Each of these nodes is configured to call the TTS API with a different voice, generating a unique MP3 audio file for that specific line.\n\n### 🗣️ TTS Service: `Kokoro`\nThis workflow uses two HttpRequest nodes to call the `Kokoro TTS API`. This service was chosen for its straightforward API and voice options.\n\nA brief explanation about the TTS setup:\n- Authentication: You must get your own API key from Kokoro. In both `HttpRequest` nodes (`Generate Audio (Voice 1)` and `Generate Audio (Voice 2)`), go to the Headers section and replace the placeholder API key in the `X-API-KEY` header.\n- Voices: To change the voices for the two speakers, modify the voice parameter in the Body of each HttpRequest node. You can find a list of available voices in the Kokoro API documentation\n\n### ✍️ How to Customize:\n- Voices: The main customization here is in the `Generate Audio (Voice 1)` and `Generate Audio (Voice 2)` nodes. You can change the voice parameter in the request body to use any of the voices your TTS service provides.\n- Cleaning Logic: The Code nodes that clean the text can be adjusted if your AI's output changes or includes other unwanted characters."

Read File: The `Read Final Merged MP3` node takes the path to the completed audio file created by `FFmpeg` and reads it from the server's disk into n8n's binary data format. This prepares it for upload.\n2. Send to Telegram: The `Send Podcast to Telegram` node takes this binary data and uploads it directly to your specified Telegram chat.\n\n### ✍️ How to Customize:\n- Delivery Channel: You can replace the `Send Podcast to Telegram` node with any other node to change the final destination (e.g., Google Drive, Discord, Email).\n- Filename: **The filename that appears in Telegram is set dynamically in the Additional Fields section of the Telegram node. You can change the format of the date or the name of the file by editing the expression there.**"
