How far back does the timeline go?

The timeline covers the stories in Alto's index, which is built continuously from the publishers Alto tracks. Long-running topics return months of coverage, while a brand-new story will show only the hours since it broke.

Why do some searches return no results?

The search matches words in headlines and article summaries. Very broad terms, misspellings, or topics no tracked publisher has covered will come back empty. Try a more specific name or phrase.

Are the articles hosted on Alto?

No. Alto aggregates and links to the publisher's original reporting. Each timeline entry credits the source outlet and links out to the full article.

Alto aggregates headlines and links to each publisher's original reporting. Inclusion is not an endorsement, and the timeline is not a fact-check.

Search any topic and this tool assembles a chronological timeline from Alto's full-text index of news coverage — every matching headline in the order it was published, with the outlet and a link to the original article.

Most timelines you find online are static articles written once and never updated. This one is generated from live coverage each time you load it, so a developing story keeps extending its own timeline.

How to use it

Type a person, place, bill, company, or event. Short, specific phrases work best — a name or a distinctive term will return a tighter timeline than a broad category. Results are ordered oldest to newest so you can read the sequence of events, and every entry links to the publisher's original report.

Why chronology matters

Coverage of a breaking story changes as facts arrive. Reading headlines in publication order shows what was reported first, what was corrected later, and which outlets led or followed. That sequence is usually invisible in a normal search results page, which ranks by relevance rather than time.

Aggregation, not adjudication

Alto aggregates headlines from a wide range of publishers and links to the source. The timeline reflects what was published and when — it is not a fact-check, and inclusion is not an endorsement of any outlet's reporting. Always read the original article before drawing conclusions.
