The Exobase is an Exonet hosted encyclopedic compendium, consisting of a small number of articles on notable locations, people, events, and technology. It is known for having concise articles that gracefully degrade to holographic AR and even to text, and is often used at extremely high latency endpoints where QuanLan is unavailable or prohibitively expensive. It is also notable for not being community edited, and for its popularity despite its lack of citations[1] and having numerous factual inaccuracies which often remain uncorrected for extended periods of time.

In 152 BFC the first version of Exobase was conceived as a subset of the larger Exopedia project by an early Synthetic Intelligence (then called third generation generative AIs) which had been tasked with finding ways to distribute simple summaries of notable facts to the numerous migrants in the Ceres Wave. It was never widely used by its intended audience, but later became popular in certain communities such as the Retrograde Diaspora and over time has become one of the most widely consulted resources by Infocom Agents in the outer solar system. The most popular feature by number of requests is the cache of InterMesh profile data about nearby people.

During the Haidian Takeoff Crisis the original synth author was decommissioned. Articles are still frequently added and updated, although the current author is unknown. One popular theory is that the Exobase is now maintained by a Cognostim stuck in a mimetic feedback loop with itself.
