What similarity preview is—and is not

Similarity preview shows textual overlap between your draft and a defined corpus—typically your project library. It helps you find forgotten quote marks, weak paraphrases, and passages pasted without attribution before you export.

It is not an institutional originality certificate. It does not access global student paper repositories unless your university integrates such a service separately. Treat preview as a drafting mirror, not a guarantee of acceptance.

Responsible use during drafting

  1. Complete citations before interpreting matches
  2. Upload all sources you heavily paraphrased
  3. Run preview on near-final drafts with stable filenames
  4. Review top matches sentence by sentence
  5. Revise or cite; do not hide text with cosmetic synonyms

How to read match reports intelligently

Colour blocks are clues, not verdicts. For each match ask: Is this a quote with marks and page number? A cited paraphrase? Common terminology in my field? Boilerplate methods text? Only uncited, unoriginal prose needs action.

Common scenarios students misread

  • High match to your own prior essay—self-citation or reuse may need disclosure
  • Match to a co-authored project—confirm collaboration rules
  • Match to web sources you forgot to upload—add source or rewrite
  • Low overall score but one long uncited block—still a problem

Align with programme policy

Read integrity guidance: some programmes cap similarity, others prohibit AI-generated text regardless of score. Combine preview with disclosure rules and supervisor expectations. If unsure, ask before submitting.

The goal is accountable originality, not gaming a percentage.

After preview: revision sequence

Fix citation gaps first, then paraphrase where voice was lost, then re-run preview. One pass is rarely enough after major edits. Keep a short log of changes for your own audit trail.

Similarity preview in Mindgrads

Mindgrads compares drafts against uploaded project sources so you can spot overlap before export. Pair preview with citation tooling and source-grounded drafting—preview catches symptoms; good sourcing prevents causes.

Conversations worth having with your programme

Ask whether similarity reports are required pre-submission, which tool is official, and how AI disclosure forms interact with scores. Programmes differ; assumptions hurt.

If a cap exists, understand whether quotes and bibliography are excluded from calculation. If excluded, mark them properly rather than paraphrasing quotations to chase percentages.

Discuss group work policies early. Shared methods sections can legitimately match; shared uncited paragraphs cannot.

Treat preview as a teaching moment: each match teaches either citation discipline or paraphrase quality. Over semesters, your first-pass quality should improve.

Summary

Use similarity preview to improve integrity before submission: cite, revise, and verify—not to chase a number. Understand its scope, ignore cosmetic fixes, and rely on your institution’s official checker when required.

Frequently asked questions

Is similarity preview the same as an official originality checker?

No. Mindgrads similarity preview compares your draft to sources you uploaded in the project, not institutional originality databases. Use your university’s designated system for official submission checks if required.

What similarity percentage is “safe”?

There is no universal safe number. Focus on whether unmatched passages are properly cited and whether uncited overlap is intentional quotation or sloppy paraphrase.

When should I run preview?

After a complete draft and citation pass, with time to revise. Running too early on partial drafts creates false confidence.

Can high similarity mean good research?

Yes—methods sections, definitions, and quoted legislation can score high while still being legitimate. Interpret matches, do not chase a target percentage.
