PII Scanner

Classifies every column from its name, its sampled values, and AI — catching personal data even in columns whose names give nothing away.

Scan tables

Governance Dashboard

A single score for how well your schema documents itself, with a ranked list of exactly what's dragging it down.

Data Quality

Profiles your tables and generates the completeness, uniqueness and cardinality checks you'd otherwise write by hand.

Run checks

Lineage

Maps foreign keys into a dependency graph, so you can see what breaks before you drop a table.

Explore lineage

Glossary AI

Derives a business glossary from your own schema — every table an entity, every shared column an attribute — and writes the definitions you never got round to.

Build a glossary

Activity Feed

Reads your database's own statistics to show what's been written, what needs vacuuming, and which tables are scanned end to end.

Metadata Chat

Ask questions about your schema in plain English. The model sees structure only — never a row of your data.

No account, no storage.MetaGuard has no user database. Your credentials live in this browser tab's sessionStorage, travel with each request over HTTPS, open one read-only connection, and are discarded when the request ends. Profiling uses aggregate queries only — no cell value is read, displayed, or sent to the AI model. Details
