Fetching an article is only the beginning of a news pipeline. The harder work is deciding whether the response is an article, whether it belongs in the product, and whether a reader can understand what was published.
I am building yocho, an AI industry news and analysis service. This is an architecture note about the work between acquisition and publication, based on the implementation and operational checks available on September 9, 2026. It is not a benchmark or a claim that every item in the collection has been processed successfully.
What I built
The service brings category-based news browsing, Japanese editorial articles, and public analysis posts into one application. Its subject matter extends from AI models to chips, infrastructure, power, and business developments.
The backend uses FastAPI and Python for database access and domain logic. PostgreSQL holds application data and the job queue; GCS holds raw archives. The Next.js frontend accesses the backend rather than connecting directly to the database.
