Recommendation engines run on embeddings. Every product, user, and preference is a vector. If one is forged or leaked across accounts, the recommendations downstream are silently wrong.
If similar items, semantic product search, or personalized feeds are part of your product, Mnemo applies. The same setup spans marketplaces, retail media, and platform SaaS. Works with your existing system.
02Why it matters
Bad data looks real without verification.
Catalog injection. A bad seller, an internal bug, or a partner pipeline pushes embeddings that do not match any authorized source. Those products get recommended anyway. Cross-account leakage. On multi-customer retail media and white-label platforms, separation between accounts rests on configuration alone. AI-generated content. Generated product images and copy produce embeddings. Without provenance, regulated categories cannot serve them safely.
03What this does
Check vectors against your own registered set.
Every catalog and preference embedding your pipeline registers carries a vector_uid in your account. Retrieval calls verify() before surfacing results; vectors that do not verify are held back. Verification is tenant-scoped: it resolves only to objects registered to your own account or namespace.
04Scope
What Mnemo does not do.
Does not replace your system
Does not score data quality
Does not filter bad data before embedding
Does not personalize on your behalf
Mnemo focuses on one layer: attaching identity to embeddings and verifying them when they are used.
Mnemo Verify checks whether a submitted vector resolves to an object registered to the caller's Mnemo account or namespace. verified=false is a safe outcome, not an error, and not proof that a vector is foreign. Verify does not establish the truth, authorship or ownership of the content behind a vector.
05Who this is for

06Why teams adopt it
Per-recommendation provenance for incident review.
Cross-border retail media networks need evidence regulators can read.
Recommendation quality debugging at corpus scale.
Tenant-scoped verification for white-label and marketplace APIs.
