Setup steps

List your RSS feed URLs in a Google Sheet
n8n loops over the feeds and caps how many items it keeps
GPT-4o-mini translates titles, groups them by theme and summarizes each theme
OpenAI text-to-speech makes an audio file, saved to Cloudflare R2
Send the digest to Gmail and LINE at 7:00

Steps summarized from the original Blog source ↗. Use “Copy” to grab them with the tools and source link, or copy an AI prompt.

How it went

The author says the digest made them stop opening Feedly. The first version (titles translated and emailed as a list) took a little over an hour to build in n8n.

Worth knowing

Running cost is about $0.08 a day in OpenAI API; Sheets, R2, Gmail and LINE were free at personal scale. They built it during n8n Cloud's free trial and note self-hosting keeps it free. ChatGPT helped write some of the formatting code.

Help me set up this automation using n8n + OpenAI (GPT-4o-mini, TTS) + Google Sheets + Gmail + LINE + Cloudflare R2: "n8n AI news digest every morning to Gmail and LINE, with audio".
Goal: replace Feedly (RSS reader).

How it should work:
- Trigger: Every morning at 7:00
- Then: Reads RSS feeds listed in a Sheet
- Then: GPT-4o-mini translates, groups and summarizes
- Then: Makes an audio version
- Result: Digest in Gmail and LINE

Setup steps (summarized from the original source):
1. List your RSS feed URLs in a Google Sheet
2. n8n loops over the feeds and caps how many items it keeps
3. GPT-4o-mini translates titles, groups them by theme and summarizes each theme
4. OpenAI text-to-speech makes an audio file, saved to Cloudflare R2
5. Send the digest to Gmail and LINE at 7:00

Guide me one step at a time. Ask me for anything you need (accounts, sheet or channel names) before you start.

Safety rules:
- Build and test with sample data first, and show me a sample result before anything goes live.
- Keep anything that goes to other people (emails, posts, replies, record updates) as drafts for my review until I say otherwise.
- Never send, post, buy, pay, delete or change records without my approval.
- Tell me about any cost (paid plans, API usage) before I'd incur it, and help me set a spending limit.
- Keep API keys and passwords out of shared docs and chats.
- Privacy: Article titles and text go to OpenAI; audio files are stored in Cloudflare R2.
