Citation Tidy

Paste a messy bibliography and get it cleaned into APA, MLA or Chicago style.

Nobody has claimed this yet. Be first.

The idea

College students paste their reference list and the app flags missing fields, inconsistent formatting and out of order entries. It rewrites each entry in the chosen style and shows what changed. It saves an hour of fiddling before every paper deadline.

Your first AI prompts

Paste these into Claude, Cursor or Lovable, in order. Check that each one works before moving on.

PROMPT 1 OF 3

Build a web app called Citation Tidy. The home page has a large text box to paste a bibliography, a style picker (APA 7, MLA 9, Chicago author date) and a Clean button. Add email login so users can save past lists.

PROMPT 2 OF 3

Send the pasted text to an AI model that splits it into entries and returns JSON per entry with fields: authors, year, title, container, publisher, doi_or_url, missing_fields and formatted_output. Show a side by side view of original and cleaned entries, with missing fields highlighted in yellow.
