Leave the doubt behind.
Enter the measurement.
Drop your two audio files: within minutes, SimiScan measures how similar they are — melody, harmony, structure, lyrics — and returns a calibrated percentage that separates a true match from a musical coincidence.
On your phone: per-criterion detail, in three minutes.
Tier ② Advanced: drop two tracks, target a chorus or a verse, and see where the resemblance comes from — melody, harmony, structure, tempo, lyrics. Result in ~3 minutes, also by email: nothing is stored on our servers.

A method, not a black box
Every criterion is measured independently, documented, and benchmarked against a statistical threshold — never a number pulled out of thin air.
Melody & harmony
Note-by-note comparison and chord progression, invariant to key transposition and tempo.
Lyrics & structure
Textual match and song architecture (verses, choruses, tempo).
Statistical calibration
Every score is positioned against a corpus of innocent pairs — a raw percentage means nothing on its own.
Verifiable integrity
Every certified report carries a fingerprint independently verifiable, no account needed, at any time.
Readable by a lawyer, verifiable by a musician.
- Two presentations, one engine — an editorial report for discussion, a paginated judicial report with cover page, criteria radar and methodology annex.
- Every figure has its audit trail — criteria kept, excluded, percentile against the reference corpus.
- Authenticatable — document fingerprint and verification QR; PDF/A and self-contained HTML export.
- Co-branding — “prepared for” your organization, SimiScan as technical signatory.

What we get asked the most.
Can SimiScan detect musical plagiarism?
SimiScan does not issue a plagiarism verdict — that is for courts to decide. The tool objectively measures the degree of resemblance between two musical works (melody, harmony, structure, lyrics) and calibrates that score against hundreds of unrelated work pairs, to distinguish a genuine match from a coincidence. This measured, reproducible score then serves as technical evidence in case of a suspected plagiarism.
How does the musical similarity analysis work?
Each comparison combines 19 independent analysis engines across melody, harmony, structure and lyrics. The result is then calibrated: the score is compared against a reference corpus of unrelated work pairs, to establish what "normal" chance produces and identify a resemblance that genuinely stands out from it.
Is a SimiScan report admissible in court?
The full expert report (Full tier) is built for exactly this: every certified report carries an independently verifiable integrity fingerprint, with a documented chain of custody for the case (import, analyses, corrections, exports). SimiScan remains a technical measurement tool, not a judicial decision — the report serves as an exhibit; the final assessment belongs to the court.
How much does a musical similarity expert report cost?
Three tiers depending on the level of detail needed: Essential (3 free trials, then €4.90/month for 10 comparisons, or €1.90 per comparison) for a calibrated score; Advanced (€59/month for 30 comparisons, or €15 per report) with per-criterion detail and precise passage targeting — the most common choice for everyday use; Full, from €490/month (5 full expert reports included, then €350 per additional report), for a report built for legal proceedings. See the plans above ↑.
Does SimiScan distinguish a sample from a cover or a mere stylistic resemblance?
Yes, SimiScan explicitly separates three cases: a literal sample (reuse of an identical recording) is detected through acoustic fingerprinting; a replayed cover (same melody/harmony performed differently) is identified through melodic note-interval matching and in-depth harmonic analysis; a mere stylistic resemblance (shared, non-distinctive chords) is explicitly flagged as such, never confused with the two cases above.
Do my audio files and data stay confidential?
Yes. Works you upload are only accessible from your account, never shared or used for any other purpose. See our privacy policy for the details, and our Security & Trust page for the technical measures.
