Send keyword-based Hacker News digests using Algolia and SMTP email

## Hacker News keyword digest Searches Hacker News (free Algolia API, no key needed) for your keywords and emails you only stories you have not seen yet. ### How it works 1. Schedule runs once a day (or use Manual Trigger to test). 2. Build Queries makes one search per keyword for the last lookbackHours. 3. Search HN calls hn.algolia.com once per keyword. 4. Pick New Stories merges results, drops stories below minPoints or already emailed, and writes the digest. 5. Send Digest emails it; Save Seen then remembers what was sent. ### Setup - Edit only the Config node. - Open Send Digest and select your SMTP credential. - Activate the workflow. The "already sent" list is kept in workflow static data, which n8n saves only for active (production) runs — manual test runs will repeat stories.
