Wordbot
It can read text pasted in by a user or at any URL, and parse tags from the text to display relevant information including rich local news search from Daylife, books search from Amazon, and web search from BOSS.
Wordbot also allows multiple users to view and comment on a document parsed by Wordbot at a hard to guess URL.
It can search for news by query, and filter results by source category and location, as well as syndicate content from a selection of sources (for example, all the media content from New York City).
Another aim of Wordbot is to promote readable text on the web. Currently, it can provide a number of readability scores for any URL.
Additionally, Wordbot provides its full text parsing library under an open source license for other PHP developers, and also provides its index of Daylife sources, which includes data about source locations, categories, and other metadata. You can get Wordbot's free stuff here.
