How to expand contractions in three steps
Paste your text
An essay, report, cover letter or AI-drafted section, up to 1,000 words per pass. The counter shows what was detected.
Expand in one click
Every contraction becomes its formal written form, with ambiguous 's and 'd resolved from the surrounding grammar.
Review and copy
Each expansion is highlighted, and hovering shows the original form, so you can verify every change before copying.
Expansion that understands the grammar
Ambiguity resolved correctly
The 's and 'd clitics expand to is, has, had or would based on what follows, the distinction most find-and-replace tools get wrong.
Possessives protected
Genitives like the author's argument are grammatically not contractions and are never touched, so meaning survives.
80+ forms covered
Standard contractions, irregulars like won't and can't, and speech forms like gonna, kinda and y'all all expand to written English.
Every change visible
Expansions are highlighted in the output with the original on hover, a worked lesson in formal register as you edit.
Contractions, register, and AI-assisted drafts
Contractions are the clearest register marker in English. Spoken language and casual prose contract by default; theses, journal manuscripts, legal documents and formal reports write the forms out. Style guides differ on many things, but on this one they broadly agree: if the document is formal, do not becomes the convention and don't becomes a distraction.
AI drafting has made this a daily problem. Chat models default to a friendly conversational register, so an AI-assisted report arrives full of it's and we've, while the sections you wrote yourself may already be formal. The seams show: inconsistent contraction use across one document reads as patchwork editing faster than almost any other signal. Expanding everything in one pass restores a single register.
The hard part is the apostrophe's double life. In it's been argued, the 's is has; in it's likely, the 's is is; in the study's aim, it is not a contraction at all but a possessive. Blind find-and-replace breaks all three in different ways. This expander parses the grammar around each apostrophe: participles trigger the perfect tense reading, pronoun heads decide whether expansion applies, and genitives pass through untouched.
One pass here handles the register. If the AI draft also needs its rhythm and vocabulary humanized before submission, the TextPulse humanizer does the sentence-level work, and this expander makes a clean finishing step.
