AI-assisted JSON filtering

Ask questions over JSON records.

zson.ai turns natural language into deterministic zson queries for logs, API payloads, DB JSON rows, event streams, and test fixtures.

{ "tenantId": "acme",

  "active": true }

$ zson '{ "role": "admin" }' users.ndjson \

Engine first

zson is the deterministic CLI and Zig library. AI suggests queries; zson executes them.
