Is PromptVault free for students?

Yes. Students can use the core library and run the included AI tester for free. Premium ($3/mo or $30/yr) unlocks unlimited tests and the full prompt vault.

Can professors detect AI-written work?

Detectors are unreliable, and any AI-generated text submitted as your own violates most schools' academic-integrity policies. PromptVault is for studying, drafting, and learning — not for submitting work you didn't write.

Does it help with research papers?

Yes — outline generators, source-evaluation prompts, and citation-format helpers are included. PromptVault never invents sources; always verify citations against the original paper.

Does it support STEM majors?

Yes. There are dedicated prompts for step-by-step math walkthroughs, lab report structuring, code debugging, and concept explanations across CS, engineering, biology, chemistry, and physics.
