Caltech permits AI for brainstorming, checking grammar, and researching the application process, but forbids using it to outline, draft, or translate your essay. It compares AI to a trusted adult who could check your essay for typos but not write it for you, and says violating the guidelines can result in a rescinded admission.
Allowed
Brainstorming, grammar and spelling checks, researching the process
Not allowed
Outlining, drafting, or translating your essay

The rule underneath every school
Whatever a specific school says, one standard applies almost everywhere: the Common App counts submitting the substantive content or output of an AI platform as your own work as fraud, added to its policy in 2023, while still permitting grammar checks and early topic brainstorming. So the safe line is always the same, use AI to think, never to write the words you submit. (More in Is It OK to Use AI? and How to Use AI the Right Way.)
Use AI on your California Institute of Technology application the right way.

Does California Institute of Technology allow you to use AI on your application?
Caltech permits AI for brainstorming, checking grammar, and researching the application process, but forbids using it to outline, draft, or translate your essay. It compares AI to a trusted adult who could check your essay for typos but not write it for you, and says violating the guidelines can result in a rescinded admission.
Can California Institute of Technology detect AI in essays?
AI detectors are unreliable and no school treats a flag as proof, so detection is not the real risk. The real risk is that AI-written essays read generic to admissions officers. Write the essay yourself and use AI only to brainstorm and get feedback.
