1.1 Workflow description

Title: Convert Gmail emails to Telegram voice messages with GPT-5 and Inworld TTS
Workflow name: Convert Gmail emails to Telegram voice messages with GPT-5 and Inworld TTS

Who’s it for

For makers, founders, and productivity nerds who want to listen to their inbox instead of reading it. No servers, no hosting — all done with n8n, a Telegram bot, and AI/ML API (LLM + TTS).

What it does / How it works

This workflow listens for new Gmail emails, extracts the sender, subject, date, and snippet, generates a 2–3 sentence natural summary using GPT-5 via AI/ML API, then converts the text into a lifelike voice message using Inworld TTS-1-Max. The final audio file is downloaded and instantly delivered to your Telegram via a bot.

A separate auxiliary flow captures your Telegram chat_id once, stores it in a Data Table, and the main flow reuses it every time — no hardcoding required.

High-level flow:

Gmail Trigger detects new incoming email
Code node builds a clean emailData block
AI/ML API (GPT-5) generates a natural spoken summary
AI/ML API (Inworld TTS-1-Max) converts summary → voice
Audio file is downloaded
Voice message is sent to the same Telegram chat

Requirements

A working n8n instance (self-hosted or cloud)
Gmail OAuth2 credentials
Telegram bot token from @BotFather
AI/ML API key
- Base URL: https://api.aimlapi.com/v1
- Supports GPT-5 and Inworld TTS-1-Max

Set up steps

Create a Telegram bot via @BotFather and add Telegram API credentials in n8n
Create an AI/ML API credential using your API key
Add Gmail OAuth2 credentials for inbox access
Import the workflow JSON
Open nodes and attach the correct credentials (no hardcoded tokens inside nodes)
Run the Telegram Trigger once and send any message to your bot — this saves your chat_id
Activate your workflow and receive your first voice-summary

How to customize

Replace GPT-5 with another LLM from AI/ML API (same schema)
Change prompt style: tone, structure, language, or verbosity
Add language selection or multi-voice support
Add filters (e.g., only important emails, only starred emails)
Log all activity to Google Sheets or a database
Add IF conditions: voice only during certain hours, weekday vs weekend rules
Add rate-limits or user allowlists
Change the voice model for different notification styles: corporate, friendly, narrator

Manage Google Calendar events with Zalo Bot, OpenAI and Gemini

## Quick Overview This workflow lets users manage Google Calendar by sending text or voice messages to a Zalo Official Account bot, transcribing voice notes with Google Gemini and using an OpenAI-powered agent to create, update, list, or delete events, then replying in Zalo with the result. ## How it works 1. Receives an incoming text or voice message through a Zalo Bot trigger. 2. Sends a typing indicator back to the Zalo chat and normalizes key message fields (chat ID, type, text, and voice URL). 3. If the message is a voice note, sends the audio URL to Google Gemini to transcribe it into text. 4. Sends the combined text/transcription to an OpenAI chat model agent that interprets the request in Vietnamese and decides whether to list, create, update, or delete a Google Calendar event. 5. Uses Google Calendar tools to get events and then create, update, or delete the targeted event based on the agent’s extracted parameters. 6. Sends the agent’s Markdown-formatted response back to the user in Zalo, and posts an error message to Zalo if the agent run fails. ## Setup 1. Install the community node package `n8n-nodes-zalo-bot-official` and restart n8n if required. 2. Connect your Zalo Bot API credentials and configure the Zalo webhook URL in your Zalo Official Account so incoming messages reach this workflow. 3. Add a Google Calendar OAuth2 credential and set the target calendar account (currently configured as `[email protected]`) for all calendar operations. 4. Add a Google Gemini (PaLM) API credential for audio transcription and ensure voice messages include a reachable `voice_url`. 5. Add an OpenAI API credential, select the chat model you want to use (currently `gpt-5-mini`), and adjust the system prompt/tone if needed.

Screen LinkedIn jobs and generate tailored resume and cover PDFs with Anthropic and DocRaptor

## Quick Overview This workflow collects your job preferences and resume via an n8n form, scrapes fresh LinkedIn job listings with Apify, screens and ranks matches using Anthropic Claude, generates tailored resume and cover letter PDFs via DocRaptor, then emails them to you and logs each match in Google Sheets. ## How it works 1. Receives a form submission with your email, target role, seniority, locations, skills, deal-breakers, and resume text. 2. Calls the Apify LinkedIn Job Scraper API to fetch up to 150 jobs posted in the last 7 days for the provided keywords and location. 3. Removes duplicates and filters out obvious mismatches based on seniority, required years of experience patterns, and location rules. 4. Uses Anthropic Claude (Haiku) to score each remaining job for relevance and eligibility and returns a JSON verdict and fit score. 5. Ranks the results, drops rejected roles, and keeps the top five best-scoring matches. 6. Uses Anthropic Claude (Sonnet) to generate a structured resume JSON and cover letter JSON tailored to each shortlisted job using only facts from your provided profile. 7. Renders the resume and cover letter to HTML, converts them to PDF files with DocRaptor, emails the PDFs to you via Gmail, and appends a tracker row to Google Sheets. ## Setup 1. Add credentials for Anthropic (Claude), Gmail, Google Sheets, and DocRaptor (HTTP Basic Auth with your API key as the username and a blank password). 2. Replace YOUR_APIFY_TOKEN in the Apify HTTP request URL and ensure you have access to the Apify LinkedIn Jobs Scraper actor endpoint used in the workflow. 3. Create a Google Sheet with a “Tracker” tab and set the document ID (YOUR_TRACKER_SHEET_ID) to match your sheet. 4. If you want non-watermarked PDFs, set DocRaptor "test" to false in both PDF generation requests.

Triage and route tasks with Google Sheets, GPT-4o-mini, Gmail, Slack, and Google Tasks

## Quick Overview This workflow collects tasks via a webhook, stores validated tasks in Google Sheets, and runs a daily prioritization routine that creates urgent items in Google Tasks with Slack alerts while summarizing medium/low tasks with OpenAI and emailing the digest via Gmail. ## How it works 1. Receives a POST webhook request containing task details and normalizes fields like priority and due date. 2. Validates required fields (including allowed priority values) and rejects invalid submissions with an error. 3. Appends valid tasks to Google Sheets with a pending status and returns a success response to the webhook caller. 4. Runs daily on a schedule, reads tasks from Google Sheets, keeps only pending items, removes duplicates, and sorts them by priority. 5. For high-priority tasks, creates a Google Tasks item and sends a Slack alert. 6. For medium and low-priority tasks, compiles a digest, generates an email-ready summary with OpenAI, and sends it via Gmail. 7. Updates each handled task in Google Sheets with a Processed status and a processed timestamp. ## Setup 1. Create a Google Sheet with columns for taskName, priority, category, dueDate, status, createdAt, and processedAt, and update the spreadsheet and sheet IDs in the Google Sheets steps. 2. Add Google Sheets OAuth2 credentials for both reading and updating/appending rows. 3. Add credentials for Google Tasks, Slack (OAuth2), Gmail, and OpenAI, and set the target Google Task list, Slack destination, and email recipients/subject as needed. 4. Copy the webhook URL from the webhook trigger and configure your task intake source to send POST requests with fields like "Task Name", "Priority", "Category", and "Due Date". 5. Adjust the schedule time and any validation rules (required fields and accepted priority values) to match your process.
