The three things students try today
Each is useful for something, and each leaves a real gap when your goal is a ranked, trustworthy shortlist of professors who fit you.
General AI chatbots
ChatGPT · Claude · Gemini
Great for drafting an email, weak for finding people. A chatbot's knowledge is frozen at its training cut-off, so the faculty it names are often outdated, incomplete, or simply invented. It can't see who is active or accepting students right now, and its picks aren't grounded in real, current pages, so you end up re-checking every single name yourself.
Manual web search
Doing it all by hand
The thorough but brutal route: open one faculty directory after another, read each profile, and judge fit by eye. Done carefully it can surface excellent matches, but building a 100-professor shortlist this way can take months, it doesn't scale, and the entire burden of finding, reading, and verifying falls on you.
University position portals
e.g. FindAPhD
These list open PhD and master's positions (mostly across Europe), not professors. Coverage is small (on the order of tens of thousands of postings), you sift through them by hand, and they match you to whatever happens to be advertised rather than to the researchers whose work actually fits your interests.
Where ApexApply fits
ApexApply searches across 3M+ active faculty worldwide, ranks them against your profile and interests, explains why each is a fit (grounded in their recent work), flags who is accepting students, and drafts tailored outreach. It turns a months-long search into about ten minutes, with almost nothing left for you to verify.
