Free Formality Checker Score Your Academic Tone
Score your draft against academic register in seconds. The checker highlights the four habits that make writing read conversational: informal words and phrasal verbs, contractions, direct address and exclamation marks, and offers a click-to-fix academic alternative for each. Built for essays, research papers, theses and reports, and for AI-assisted drafts whose register drifts from paragraph to paragraph.

How to check formality in three steps
Paste your text
An essay, a manuscript section, a cover letter or a report, up to 1,000 words per pass.
Read the score
A 0-100 formality score with a verdict band, plus counts of informal words, contractions, direct address and exclamation marks.
Click to fix
Underlined items swap to their academic alternative on click: a lot of becomes many, figure out becomes determine. The score updates as you work.
Why this formality checker is different
Four signals, one view
Informal vocabulary, contractions, direct address and exclamation marks are flagged together, so one pass covers the habits that matter most for register.
Click-to-fix suggestions
Each flagged item carries a plain academic equivalent where one exists, applied with a click. Phrasal verbs are matched by inflection: figured out becomes determined.
A score you can act on
Marker density per hundred words, mapped to bands calibrated for academic prose. Watch the score climb as you work through the highlights.
Current conventions, not myths
First person is not flagged: APA and major journals accept "we" and "I". The checker targets what actually reads as informal today, not folklore rules.
Register: the fastest judgement your writing faces
Every reader of formal work carries a register detector they cannot turn off. A professor marking essays, a reviewer skimming a manuscript, a committee reading a grant application: all of them notice "a lot of" where the literature says "many", and "we couldn't figure out why" where a paper would say "the mechanism remains unclear". The judgement happens in milliseconds and colours everything that follows. Register is not a decoration on top of the content; it is part of how the content is weighed.
Formal register in English is built from a few consistent choices. Single precise verbs replace phrasal ones: examine rather than look into, determine rather than figure out. Contractions are written out. The reader is never addressed as "you"; claims carry measured quantifiers rather than intensifiers; and the exclamation mark does not appear. Each choice removes a marker of speech from prose that will be read, quoted and judged in print. AI-assisted drafts need this pass more than most: chatbots switch register with the prompt, so a document revised across several sessions often mixes formal and conversational phrasing in the same paragraph, and the inconsistency reads as carelessness even when every sentence is grammatical.
The opposite failure is just as real. Writers warned about informality sometimes swap every plain word for a longer one, and the result is the stilted prose style guides call inflated: "utilize" for "use", "commence" for "begin". Genuine academic register is plain, precise and unhurried, not ornate. The checker's suggestions are chosen on that principle: the alternative to "figure out" is "determine", not "elucidate".
Formality is one dimension of a draft that reads well. For the contraction sweep on its own, use the contraction expander; for the vocabulary AI models overuse, the AI word cleaner; and when tone, rhythm and phrasing all need rewriting together, the TextPulse humanizer.
Informal to academic: the swaps that come up most
A working reference drawn from the checker's lexicon. Each is a plain equivalent, not a decorated one.
Phrasal verbs
Speech joins a small verb to a particle; academic prose prefers the single precise verb.
Vague quantities and nouns
Casual measures read as guesses; formal equivalents carry the same meaning with more precision.
Casual connectors
Sentence-openers borrowed from conversation, each with an established academic counterpart.
Habits to remove
Not swaps but subtractions: features of speech that formal prose simply drops.
