About Meridian
Your daily news, distilled by AI, verified by AI.
What is Meridian?
Meridian is a free daily news briefing that delivers the top 20 stories from 30+ trusted publications. Every morning at 5:00 AM UTC, we scan hundreds of articles, identify the most important stories, and deliver clear, neutral summaries directly to your inbox.
Unlike traditional news aggregators, Meridian doesn't just collect headlines — it synthesizes multiple perspectives into cohesive summaries, giving you a complete picture of each story without the noise.
How It Works: The Dual-AI Approach
Aggregate & Cluster
Every few hours, we scan 30+ trusted news sources across world news, US news, tech, business, science, and EU news. Articles covering the same story are grouped together using semantic similarity, ensuring we capture multiple perspectives on each event.
AI #1: Write the Summary
The first AI system (powered by OpenAI's GPT-4o-mini) reads all articles in each story cluster and generates a clear, neutral summary. It synthesizes key facts, identifies the most important developments, and writes in a consistent, professional tone. This AI is optimized for accuracy and readability.
AI #2: Review & Verify
A completely independent second AI system (powered by Anthropic's Claude) reviews every summary before publication. It checks for:
- •Accuracy: Are all claims supported by the source articles?
- •Neutrality: Is the language balanced and free of bias?
- •Completeness: Are the most important facts included?
- •No Fabrication: Does anything appear that isn't in the sources?
If issues are found, the summary is automatically rewritten and re-reviewed until it passes all quality checks.
Deliver to You
Only after every summary passes the dual-AI review do we publish the edition. You receive the top 20 stories, ranked by importance based on source diversity and recency, delivered before your morning coffee.
Why Two AI Systems?
Single AI systems can make mistakes — they might hallucinate facts, introduce subtle biases, or miss important context. By using two completely independent AI systems from different providers, we create a natural system of checks and balances.
The reviewing AI has no knowledge of how the writing AI works, and vice versa. This independence helps catch errors that a single system might miss, resulting in more accurate and reliable summaries.
Our Sources
We aggregate from 30+ established news organizations across six categories, prioritizing editorial sources with strong journalistic standards.
We do not include opinion pieces, editorials, or sponsored content in our summaries. All source links are provided with every story.
Limitations & Transparency
AI Disclosure: This content is AI-generated. Summaries are generated by AI and independently reviewed by a second AI system for quality and neutrality. Despite this dual review process, summaries may still contain inaccuracies. Always refer to original sources.
While our dual-AI system significantly reduces errors, no AI is perfect. We always provide links to original sources so you can verify information and read primary reporting when you need more depth.
