Workflow name: Daily AI news digest from Hacker News with GPT-5 summaries and email delivery

Daily AI News Digest from Hacker News with GPT Summaries and Email Delivery

Automate your daily AI news briefing: fetch AI-tagged stories from Hacker News, filter for the last 24 hours, scrape and summarize with GPT, then deliver a clean HTML email digest—no manual curation needed.

What It Does

Runs on schedule to fetch up to 1000 Hacker News stories tagged "AI", filters for today's posts, loops through each to scrape content from source URLs, generates concise AI summaries via OpenAI GPT, aggregates into a styled HTML newsletter, and sends via email.

Setup Requirements

Credentials Needed:

OpenAI API Key: Get from platform.openai.com/api-keys, add as "OpenAI" credential in n8n
SMTP Server: Configure email credentials (Gmail, Zoho, etc.) in n8n's SMTP settings

Configuration Steps:

Import workflow JSON into n8n
Add OpenAI credential to "GPT 5 pro" node
Add SMTP credential to "Send email" node
Update fromEmail and toEmail fields in "Send email" node
Set schedule in "start" trigger node (default: daily)
Activate workflow

Key Features

Smart Filtering: Fetches 1000 stories, filters last 24 hours using date expressions
AI Summarization: GPT generates heading + 2-sentence summaries with links
Reliable Scraping: HTTP requests with markdown conversion for clean LLM input
Batch Processing: Loops through items, processes sequentially
Responsive Design: Mobile-friendly HTML email template with inline CSS
Aggregation: Combines all summaries into single digest

Customization Options

Change Keywords: Modify "AI" filter in "Get many items" node
Adjust Timeframe: Edit date filter in "Today" node
Tweak Summaries: Customize GPT prompt in "News Summary Agent" node
Email Styling: Update HTML/CSS in "Send email" node
Schedule: Change frequency in "start" trigger

Use Cases

Personal daily AI briefings for researchers/developers
Team knowledge sharing via automated newsletters
Content curation for blogs or social media
Trend monitoring for marketers

Troubleshooting

No stories returned: Check HN API limits, verify keyword filter
Scraping failures: Some sites block bots—proxy noted in workflow but may need updates
Email not sending: Verify SMTP credentials and test connection
Poor summaries: Adjust GPT prompt or switch model

Execution Time: 2-10 minutes depending on story count

Promote YouTube uploads to social channels with DeepSeek and Posta

## Quick overview This workflow fetches the latest video from a YouTube channel feed, generates platform-specific promo captions with DeepSeek, and creates draft promotion posts in Posta for active social media accounts. You can automatically promote your videos to all your social media. Add a "publish" at the end for auto-post. ## How it works 1. Runs manually when you click “Execute workflow”. 2. Fetches your YouTube channel RSS feed over HTTP, parses the XML, and extracts the latest video’s title, description, thumbnail URL, and link. 3. Downloads the video thumbnail and uploads it to Posta to create a reusable media asset. 4. Retrieves your social accounts from Posta, keeps only active accounts, and de-duplicates them to one account per platform. 5. Combines the latest video data with each target platform and asks DeepSeek (via an n8n LangChain LLM chain) to write a tailored promotional caption per platform. 6. Tags each generated caption with its platform and merges it back to the matching Posta social account. 7. Creates a draft Posta post per selected account, attaching the uploaded thumbnail and the platform-specific caption and video link. 8. (Optional) Add a "publish a post" at the end to automatically post to the social media channels (If you are feeling brave and trust the LLM), ## Setup 1. Add a Posta API credential and select it in the Posta nodes that list accounts, upload media, and create posts. 2. Add a DeepSeek API credential and select it in the DeepSeek Chat Model node. 3. Update the YouTube channel feed URL (channel_id) in the HTTP request that downloads the YouTube feed. 4. Review your Posta social accounts to ensure the intended accounts are marked active and have the correct platform values for de-duplication. ## Additional info Video explanation: https://youtu.be/tTWaYb71YyA

Post scheduled Threads updates from Google Sheets with error tracking

## Quick overview This workflow runs hourly to read the next pending post from Google Sheets, publishes it to Threads via the Threads Graph API, and then updates the sheet with published or failed status plus timestamps and error details. ## How it works 1. Runs every hour on a schedule. 2. Reads the first row in Google Sheets where the status column equals pending. 3. Retrieves the authenticated Threads account’s user ID from the Threads Graph API. 4. Creates a Threads text post container using the content from the pending Google Sheets row. 5. Publishes the post to Threads and updates the same Google Sheets row as published with posted_at and updated_at timestamps. 6. If any Threads API call fails, records the error message and marks the corresponding Google Sheets row as failed with an updated_at timestamp. ## Setup 1. Create a Meta app and generate a Threads access token, then add it to an HTTP Header Auth credential used for the Threads Graph API requests. 2. Set up a Google Sheets Service Account credential in n8n and share your target spreadsheet with the service account email. 3. Replace the placeholder Google Sheet ID in all Google Sheets nodes and confirm the sheet name is Sheet1 (or update it to match your sheet). 4. Ensure your sheet has the required columns (row_number, content, status, posted_at, updated_at, error_message) and set status to pending for posts you want published.

Send a daily product newsletter with Google Sheets and Gmail

## Quick Overview This workflow runs daily at 08:00, pulls products scheduled for today from Google Sheets, generates an HTML newsletter email, and sends it to each subscriber via Gmail. ## How it works 1. Runs every day at 08:00 on a schedule. 2. Reads all rows from the `newsletter_products` sheet in Google Sheets. 3. Keeps only products whose `send_date` matches today’s date and stops if none are found. 4. Builds an HTML email and subject line containing a card for each product (image, description, and optional referral link). 5. Reads the subscriber list from the `newsletter_recipients` sheet in Google Sheets. 6. Sends the generated newsletter to each recipient individually using Gmail. ## Setup 1. Create or copy a Google Sheets document with `newsletter_products` (including a `send_date` column) and `newsletter_recipients` (including an `email` column). 2. Add a Google Sheets OAuth2 credential in n8n and paste your Google Sheet ID into the Config step. 3. Add a Gmail OAuth2 credential and confirm the sender mailbox to use for sending the newsletter. 4. Add products and recipients to the sheet, run a test execution, and adjust the schedule/timezone if needed before activating.
