Short answer

What makes writing sound academic?

Four things, in order of impact: precision (specific claims over vague ones), attribution (every borrowed idea sourced), measured confidence (hedge where evidence is genuinely uncertain, state plainly where it is not), and register (full forms rather than contractions, specific nouns rather than “things”). Formality is the least important of the four, and the one students over-correct hardest — long words do not substitute for a clear argument.

Frequently asked questions

Is this sentence grammatically correct?
Paste it above and the checker will flag the mechanical problems it can detect: length, passive construction, informal register, contractions and locale-inconsistent spelling. It cannot judge meaning — for that, a marker or a tutor has to read it.
Is my text uploaded anywhere?
No. The entire analysis runs in your browser in JavaScript. Nothing is sent to a server, stored, or logged. That matters for unpublished work, which is the main reason we built it this way rather than calling an API.
Should I avoid passive voice completely?
No. Passive voice is standard and often preferred in methods sections — 'samples were collected' keeps the focus on the procedure. It weakens argumentative writing, where naming the actor is stronger: 'Smith argues' rather than 'it is argued'.
How long should an academic sentence be?
Aim for an average of 15–25 words. Anything past about 40 words is where markers start losing the thread. Vary the length deliberately — a short sentence after a long one lands the point.
Can I use contractions in academic writing?
Generally no. Most academic style guides expect full forms — 'do not' rather than 'don't'. Possessive apostrophes such as 'the study's findings' are always fine, and reflective writing is sometimes more relaxed.
