Mask Databases / Query examples

Find users who signed up in the last 30 days

MongoDB query compiled from plain English against the saasUsers sample schema, then verified by running it.

The compiled query

{
  "type": "find",
  "collection": "users",
  "filter": {
    "createdAt": {}
  }
}

How the compiled query works

Write this in plain English instead. Mask Databases compiles the sentence above into exactly this query at build time — no AI at runtime, and you can read the output in a diff.
