Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for automatic text suggestion are described. In general, one aspect of the subject matter described in this specification can be embodied in a method that includes, from an authoring environment, receiving a request to supplement a text segment; submitting a query to a search engine, the query being generated from the text segment; receiving multiple search results from the search engine in response to the query, each search result including an information snippet; generating one or more suggestions for supplementing the text segment based on the information snippets; and providing the one or more suggestions for supplementing the text segment for display in the authoring environment.
