Why originality matters
“Original” writing means your ideas are clear, supported, and in your own words. This tool helps you:
- show your voice (reduce repetition, use active verbs),
- keep clarity high (shorter sentences, simple words),
- and credit sources (healthy citation density, not too many quotes).
Original writing is built on understanding sources—start by reading our guide on Literature Review for Students.
Tips for students
- Summarize, then cite. Use your own words before adding a short quote.
- Prefer active voice. “We tested the sample” is clearer than “The sample was tested.”
- Split long sentences. Aim for 10–18 words for most school writing.
- Replace repeats. Vary phrases like “in conclusion” or “in this study.”
FAQs
Is Originality Coach a plagiarism checker?
No. It does not search the web or journal databases. It checks originality signals—readability, passive voice, citation density, quotes, and repetition—so you can revise before running a separate plagiarism checker if your school requires it.
Is the tool free for students?
Yes. The core features are free and run in your browser—no sign-up required.
What writing styles does it support?
General, Academic, Professional, Informal, and Technical. Targets for readability, sentence length, and passive voice adjust to the style you pick.
Does the tool store my text?
No. Analysis happens locally in your browser; we don’t store your input.
What does “Citations/100w” mean?
It’s the number of citations per 100 words (APA/MLA patterns, numeric [1], URLs, DOI). A higher value generally shows stronger source support.
What does “Variety (CV)” measure?
It’s the variation of sentence lengths. Low CV can feel monotone; very high CV can feel choppy. Aim for a balanced range.
How can I reduce passive voice?
Rewrite so the subject does the action (e.g., “We tested the sample” instead of “The sample was tested”).
Can I export my results?
Yes. Click Copy Report to copy metrics, findings, repeated phrases, and your final text into your clipboard.
