Hacker News, TechCrunch and arXiv Briefing

Overview

Research papers, company reporting, and technical discussion rarely arrive with shared labels, so related developments are easy to miss when you read each source alone. This workflow gives you one cross-source briefing that connects Hacker News discussion, TechCrunch reporting, and arXiv research while preserving the source behind each item. A feed-seeding script passes the three source groups to Collect Feeds, then the agent identifies overlaps and writes Markdown and HTML artifacts for review. You can schedule the briefing and inspect each stage in Trickest workflows, making this a source-correlation workflow rather than a general tech or AI news digest.

Pipeline

1. Seed Feed List creates the configured Hacker News, TechCrunch, and arXiv RSS input list.
2. Collect Multi-Source Feeds reads each RSS input and returns normalized feed items with source links.
3. Write Daily Briefing compares the normalized items and writes a briefing organized around cross-source connections.
4. Publish Briefing Files converts the completed briefing into Markdown and HTML artifacts.

Inputs

• RSS feed list. Public Hacker News, TechCrunch, and arXiv feed URLs, limited to the source groups you want to compare.
• Topic filters. Optional research or technology terms, left empty when you want broad cross-source coverage.
• Briefing guidance. Optional length and section instructions, kept concise so source relationships remain visible.

Outputs

• Markdown briefing. A source-linked document grouping related research, reporting, and community discussion.
• HTML briefing. A browser-readable version of the same cross-source analysis.

Integrations

• Collect Feeds for retrieving and normalizing public RSS items.
• AI for comparing coverage and composing the briefing.
• Trickest workflow runtime for graph execution and artifact review.

Sample output

The artifact below is an illustrative sample. Every title, author, identifier, and summary is fictional, and it does not describe current coverage or live metrics.

# Illustrative cross-source briefing
 
Data status: Fictional example input
 
## Topic: Compact model evaluation
 
### arXiv
"A Fictional Benchmark for Compact Models" proposes an invented evaluation set.
 
### TechCrunch
"Example Lab Tests Smaller Models" reports on a fictional product trial.
 
### Hacker News
"Discussion: What should compact model benchmarks measure?" contains an
invented community discussion about evaluation criteria.
 
### Cross-source connection
The fictional paper defines the benchmark, the fictional report describes a
trial, and the fictional discussion questions which criteria matter.

FAQ

Why combine Hacker News, TechCrunch, and arXiv?

Each source represents a different layer of a development. arXiv carries research, TechCrunch reports company and product activity, and Hacker News surfaces technical discussion, so comparing them exposes connections a single-source digest can miss.

How is this different from a daily tech digest?

This workflow starts with three named source groups and organizes the briefing around relationships among them. A daily tech digest instead curates a broader feed set around general technology news.

How is this different from a daily AI news digest?

The briefing is not limited to AI and does not rank a general AI news stream. It compares Hacker News, TechCrunch, and arXiv items when their topics overlap.

Can I add or replace RSS sources?

Yes. Change the feed list in the Seed Feed List step, then verify that each replacement publishes valid RSS and that you have permission to retrieve it.

Can the briefing run on a schedule?

Yes. Set a cadence in the workflow editor to produce a consistent cross-source review.
