Free Formality Checker Measure Your Academic Register
Paste a draft and this formality checker returns a 0-100 register score in seconds, tracking four markers that make prose sound spoken rather than written: casual wording carried over from speech, contractions, a direct nod to the reader, and any stray exclamation point, each paired with an academic swap you can apply in one click. Suited to essays, manuscripts, theses and reports, including sections an AI assistant touched where the register drifts between paragraphs.
Scores your draft 0-100 against academic register: informal words, contractions, direct address and exclamation marks.

Add your draft
A thesis chapter, a conference abstract, a cover letter or a full report, up to 1,000 words per pass.
See the register score
A 0-100 number inside a verdict band, broken down into separate tallies for spoken-style wording, contractions, reader address and exclamation points.
Resolve each flag
Underlined phrases swap to their academic equivalent on click, a lot of into many, figure out into determine, and the score updates as you go.
Why this formality checker is different
Four register markers tracked together
Spoken-style word choice, contractions, a direct nod to the reader and exclamation points all surface in one scan, covering the habits that most affect how formal a passage reads.
One click swaps the phrase
Each flagged item carries a plain academic alternative and applies it instantly, with phrasal verbs matched across inflections, so figured out becomes determined too.
A number that moves as you edit
Marker density per hundred words, mapped onto bands built for academic prose specifically, rising as flagged items get resolved.
Rules that match how journals write today
First person stays unflagged, since APA and the leading journals accept "we" and "I" without reservation. The checker flags what reads as casual today, based on current usage instead of outdated style advice.
Register as the first thing a reader judges
Every reader of formal writing runs a register check without meaning to. A professor working through a stack of essays, a reviewer skimming toward the results, a committee weighing a grant application: each one notices "the results were kind of significant" where the literature would say "the results reached significance", and "we got rid of the outliers" where a published paper would read "outliers were removed". That judgement forms before the reader consciously notices making it, and it colors the pages that follow. That snap judgement folds straight into how the argument itself gets weighed.
English builds its formal register from a short list of consistent choices. A single precise verb stands in for the phrasal pair: investigate replaces look into, address replaces deal with. Contractions get spelled out in full. The reader is never named "you". Claims lean on measured quantifiers instead of intensifiers, and the exclamation mark stays out of the piece entirely. Each of these choices strips away a marker of casual speech from writing that will be read, quoted and judged on the page. Drafts touched by AI assistance need this pass more than most, since a chatbot's register resets with every prompt, and a document revised across several sessions frequently mixes formal and conversational phrasing inside a single paragraph.
The opposite mistake is just as common. Writers told their prose reads too casually sometimes trade every plain word for a longer one, landing on the inflated style guides caution against: "utilize" instead of "use", "commence" instead of "begin". Genuinely formal academic writing stays plain and exact rather than ornamental, and the equivalents this checker suggests hold to that line: the fix for "deal with" is "address", never something as rare as "adjudicate".
Register is one layer of a manuscript that reads well. For contractions specifically, the contraction expander handles the sweep on its own; for the vocabulary AI drafting tools lean on too heavily, there is the AI word cleaner; and when tone, rhythm and phrasing all need rebuilding together, the TextPulse humanizer takes on the full draft.
The substitutions this checker applies most often
Pulled straight from the tool's own lexicon. Every replacement stays plain; none of them are the dressed-up kind.
Verb-plus-particle phrases
Speech pairs a short verb with a particle; scholarly prose reaches for the single verb that means the same thing.
Imprecise amounts and vague nouns
A casual measurement reads as a guess; its formal counterpart says the same amount with precision.
Spoken-register connectors
Openers borrowed straight from conversation, each with a settled scholarly equivalent already in wide use.
Patterns the checker deletes outright
Not a substitution but a removal: traits of speech that formal prose leaves out entirely.
Who uses the formality checker
Undergraduates
Bring an essay up to the register an instructor expects, picking up the academic form of each casual habit along the way.
Second-language academic writers
Register is often the hardest layer of writing in a second language. This tool shows precisely which choices sound spoken rather than written, and which term takes their place in published academic prose.
Faculty and PhD candidates
Run a manuscript or thesis chapter through before a supervisor or reviewer does, especially sections written quickly or drafted with AI help.
Corporate and policy writers
Give a proposal, report or cover letter the institutional weight its first, chattier draft was missing.
