By listening instead of reading, users can soak in the info in a fun and easy way.\n\nThis project rocks a workflow using n8n to automate tasks like a boss. Each node in the workflow plays its part in a smooth operation. Check out the main players:\n\n1. **Gmail trigger1 Node**: Kicks off the action every minute for those \"CATEGORY_PROMOTIONS\" emails.\n   \n2. **Get message content1 Node**: Grabs the email content for some magic.\n      \n3. **Summarization Chain3 Node**: Whips up some sweet summaries using fancy chunking methods.\n   \n4. **Delete the unnecessary items Node**: Clears out the clutter from the email content.\n   \n5. **Text to Free TTS Node**: Turns the summary into speech using Free TTS magic.\n   \n6. **Convert from base64 to File Node**: Changes the audio into a file format.\n   \n7. **Merge Text with Audio Node**: Mixes the text and audio together for a cool combo.\n   \n8. **Aggregate in same cell Node**: Puts all the data together for more awesomeness.\n   \n10. **Send Message to Telegram Node**: Sends the final audio message with a caption to a special Telegram chat ID.\n\nThis workflow is like a well-oiled machine, with each step flowing seamlessly into the next. By automating these tasks, this project aims to make communication a breeze and bring joy to all involved! \ud83c\udf08\u2728\ud83d\ude80\n"}, "typeVersion": 1}, {"id": "07a4dc07-0109-464e-a661-d5a4bb7b4a1c", "name": "Get message content1", "type": "n8n-nodes-base.gmail", "position": [640, 460], "parameters": {"simple": false, "options": {}, "messageId": "={{ $json.id }}", "operation": "get"}, "credentials": {"gmailOAuth2": {"id": "UJx4Tiq8WRtxWEIP", "name": "Gmail Omar"}}, "typeVersion": 2.1}, {"id": "283dcd8b-80a8-4e49-aba1-fabec333def3", "name": "OpenAI Chat Model3", "type": "@n8n/n8n-nodes-langchain.lmChatOpenAi", "position": [1120, 640], "parameters": {"options": {}}, "credentials": {"openAiApi": {"id": "6u6TSayQDxci71Wb", "name": "OpenAi account"}}, "typeVersion": 1}, {"id": "71897790-5ee8-4f15-bc4e-26a987b79505", "name": "Delete the unnecessary items", "type": "n8n-nodes-base.code", "position": [880, 460], "parameters": {"jsCode": "// Loop over input items and add a new field called 'myNewField' to the JSON of each one\nfor (const item of $input.all()) {\n delete item.json.threadId;\n delete item.json.labelIds;\n delete item.json.sizeEstimate;\n delete item.json.headers;\n delete item.json.html;\n delete item.json.to;\n delete item.json.cc;\n delete item.json.replyTo;\n delete item.json.messageId;\n delete item.json.id;\n delete item.json.textAsHtml;\n delete item.json.date;\n\n}\n\nreturn $input.all();"}, "typeVersion": 2}, {"id": "187704ba-ddc1-447e-99f6-8335b039dca3", "name": "Aggregate in same cell", "type": "n8n-nodes-base.aggregate", "position": [1400, 660], "parameters": {"options": {"includeBinaries": true}, "aggregate": "aggregateAllItemData"}, "typeVersion": 1}, {"id": "a8cba2a0-e751-4dc4-8cc1-9b91c587b1bc", "name": "Gmail trigger", "type": "n8n-nodes-base.gmailTrigger", "position": [440, 460], "parameters": {"simple": false, "filters": {"labelIds": ["CATEGORY_PROMOTIONS"]}, "options": {}, "pollTimes": {"item": [{"mode": "everyMinute"}]}}, "credentials": {"gmailOAuth2": {"id": "UJx4Tiq8WRtxWEIP", "name": "Gmail Omar"}}, "typeVersion": 1}, {"id": "7d170a4c-601e-49da-a834-2a40f992feff", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [1380, -340], "parameters": {"color": 5, "width": 478.42665735513924, "height": 651.7534899914576, "content": "### This API allows automatic text-to-speech generation.\nYou can utilize this API by sending a POST request to the specified link and including JSON data containing the text you want to convert to speech, along with selecting your preferred voice.\n\nWhen using this API, make sure to include the `Content-Type` header with the value `application/json` to ensure proper interpretation of the request data.\n\nThe API offers a user-friendly interface where you can simply submit the desired text and choose the appropriate voice, then receive an audio file containing the generated speech.\n\nUsing this API can be beneficial for quickly generating audio clips for texts in an efficient manner.\n\nYou can access this API at [https://tiktok-tts.weilnet.workers.dev/api/generation](https://tiktok-tts.weilnet.workers.dev/api/generation) or keep it as is without changing anything as provided on [https://tiktokvoicegenerator.com/](https://tiktokvoicegenerator.com/). \n"}, "typeVersion": 1}, {"id": "f0809138-4bde-4132-97b2-0810b920ed7a", "name": "Convert from base64 to File", "type": "n8n-nodes-base.convertToFile", "position": [1660, 140], "parameters": {"options": {}, "operation": "toBinary", "sourceProperty": "data"}, "typeVersion": 1.1}, {"id": "2efdd685-57fe-4f5c-b295-183dddfeb0d6", "name": "Merge Text with Audio", "type": "n8n-nodes-base.merge", "position": [1720, 440], "parameters": {}, "typeVersion": 2.1}, {"id": "c59a00fd-c7c7-4dc5-91d1-492bd7715731", "name": "Send Message to Telegram", "type": "n8n-nodes-base.telegram", "position": [1720, 660], "parameters": {"chatId": "53739339", "operation": "sendAudio", "binaryData": true, "additionalFields": {"caption": "={{ $json.data[1].response.text }}", "fileName": "New Message on Gmail"}, "binaryPropertyName": "=data"}, "credentials": {"telegramApi": {"id": "inUwZEIEWHK1poKe", "name": "aqsati services"}}, "typeVersion": 1.1}, {"id": "3f3a1209-9787-41c3-af10-3f3e44a89c9b", "name": "Summarization Chain3", "type": "@n8n/n8n-nodes-langchain.chainSummarization", "position": [1120, 460], "parameters": {"options": {"summarizationMethodAndPrompts": {"values": {"prompt": "Craft a concise newsletter using the given content.
