History
Particle is a mobile-first AI-powered news aggregation app launched in 2024 by a team of former Twitter engineers.

The service aggregates headlines from multiple sources, offering a streamlined overview with links to full articles. Particle was founded in 2023, backed by $4.4 million in seed funding and a $10.9 million Series A, and is headquartered in Larkspur, California. According to a BusinessWire press release, Particle expanded to a full website in May 2025, building on its original iOS app.

Analysis / Bias
Particle’s user interface aggregates headlines and generates AI story summaries from a variety of sources, organizing them by topic. While it claims to deliver a “zoomed-out” view of the news, its story curation often lacks balance in source quality. For instance, the story “Trump escalates mass deportations in Democratic-run cities” draws on The Blaze, a highly biased source with a poor MBFC factual rating, suggesting Particle does not consistently vet sources for credibility.
In the article “Vance Boelter arrested in targeted shootings of Minnesota lawmakers”, the site includes a summary with links to sources that span both left- and right-leaning outlets, though more appear to lean left (e.g., MSNBC, NBC News) than right. Although Particle does not produce original journalism, its summaries may inherit the framing and bias of the sources it links to, particularly when using outlets with poor fact-checking records.
Failed Fact Check
- There are no known direct fact-check failures attributed to Particle itself, but the site regularly promotes or links to sources with poor factual accuracy, which diminishes its overall reliability.
Overall, we rate Particle as Least Biased based on minimal editorializing of content, but Mostly Factual due to its inclusion of unreliable sources. (D. Van Zandt 06/16/2025)
