FAQ
Common questions before choosing a generator.
If your instructions are unclear, start here before opening a style-specific generator.
Which citation generator should I choose?
Use the format named in your assignment, syllabus, journal instructions, or style guide. If no style is named, choose by subject: APA for many social science papers, MLA for literature and writing courses, Chicago or Turabian for humanities, AMA or Vancouver for medical writing, ACS for chemistry, and IEEE for engineering or computer science.
What if my citation is missing details?
Do not copy it blindly. Open the result, add the missing author, date, page range, publisher, DOI, or URL if you can find it on the source, then copy the citation.
Can I change a citation before I copy it?
Yes. After the generator finds a source, you can adjust title casing, author order, publication date, volume, issue, pages, URL, DOI, and other source details before copying.
Which formats work best for science, medical, or engineering sources?
Medical and public health writing often starts with AMA or Vancouver. Chemistry and materials science usually use ACS. Biology and environmental science may use CSE. Engineering, computer science, and conference papers often use IEEE.
Are the citation tools free?
Yes. You can open a generator, enter source information, edit the citation, and copy the result without creating an account.
