Source similarityAutomatically search free public sources; optional private references

Compare against a reference passage locally

Reference text

Five-word exact matches only. The percentage is not an academic misconduct verdict.

Automatic free public-source search on AnalyzeShort selected excerpts—not your complete document—are sent to Wikipedia, Crossref and Europe PMC. Coverage is limited; switch off here or above at any time.

● Built-in checker ready

🔒 Grammar and spelling run locally. With the default free web scan enabled, clicking Analyze sends a few short text excerpts to Wikipedia, Crossref and Europe PMC (not the entire file). Turn this off above to keep analysis local. Some document import libraries load from public CDNs; formatting may be lost.

Connection diagnostics Optional, does not send your draft

Test availability using fixed public queries and a built-in sample. Your document is not shared.

You're on the right track!

Small improvements can make your writing clearer and more confident.

Free and account-free. Source similarity reflects only checked material, not a plagiarism verdict. How it works

Make your writing shine ✨

1. Paste a draft or choose a file.
2. Click Check my writing.
3. Read a suggested change and apply, dismiss, or edit it.
4. Online source checking runs with Analyze by default and sends short excerpts; switch it off above for local-only checks. Optional reference comparison is separate.
5. Export your reviewed text or report.

Academic advice is contextual. Source-match percentages only describe checked material, not proof of plagiarism.
