What is cs.princeton.edu?

cs.princeton.edu is the official website of the Computer Science Department at Princeton University. It serves as the department's public-facing hub for information about its research, undergraduate and graduate programs, courses, news, and events. It is an academic department site, not an online course platform, a commercial service, or a general-purpose computer science learning resource.

Who the site is for

The site addresses several distinct audiences:

• Prospective and current students — people exploring Princeton's undergraduate or graduate computer science programs, or already enrolled and looking for course and program details.
• Faculty, researchers, and academic peers — visitors interested in the department's research areas, faculty, and scholarly activity.
• Journalists and the general public — anyone following department news, awards, and events.

If you are looking for free online courses, coding tutorials, or a commercial product, this is not that kind of site.

What content the site covers

Based on the site's own navigation and news listings, the main content areas are:

The news section is updated regularly and reflects the department's ongoing activity. Examples drawn from the site's own listings include:

• Coverage of whether AI models can perform research judgment, not just solve mathematical puzzles.
• Five computer science graduate students named 2027 Siebel Scholars.
• The arrival of Abhishek Bhattacharjee, an expert in computer architecture, operating systems, and neurotechnology.
• Research showing AI tools can miss basic details in police bodycam footage in roughly 1 in 4 cases.
• Alex Lombardi receiving an NSF CAREER award for work in cryptography.
• A senior thesis spotlight on an LLM challenge combining computer science and linguistics.

These items illustrate the site's role: it reports on the department's people, research, and accomplishments rather than teaching computer science itself.

What it is not

It is worth being explicit about the boundaries, since the domain name could be mistaken for something else:

• Not an online course platform. The "Courses" section describes Princeton's course offerings; it is not a MOOC or a place to enroll in standalone online classes.
• Not a commercial service. There is no product, subscription, or paid service being sold here. The site does reference a "subscribe" option, but that relates to following news updates, not purchasing anything.
• Not a general CS reference site. It is specific to one university department.

How to use it

• If you want to understand what Princeton's CS department does, start with the Research and Recent News sections.
• If you are considering applying or enrolling, go to the Undergraduate or Graduate sections.
• If you want to know what courses exist, use the Courses section.
• If you want to follow department activity, the news area is where updates appear.

The site is in English and is aimed primarily at the Princeton CS community and academic audiences, though its news and research content is publicly readable by anyone.
