Particle
Particle is an AI-powered news reader built by former Twitter engineers Sara Beykpour and Marcel Molina. It summarizes the day's stories from many sources, shows the political spread of coverage, extracts key quotes, and links prominently back to the publishers it draws from - positioning itself as an AI news product that pays and drives traffic to journalists rather than scraping them. Available on iOS, Android, and the web, Particle is developed by San Francisco-based Mina Labs and has raised $15.3M.
