SQL Server includes schema browsing, transactional row editing and foreign key diagrams. DynamoDB includes item browsing and PartiQL queries with AWS credentials. Cassandra includes keyspaces, native paging and CQL queries. DynamoDB and Cassandra use the query editor for changes; full-text table search is unavailable.

Your words. Ready-to-run SQL.

Describe what you need. AI uses your schema to write a query you can review and run.

Connect ChatGPT, an OpenAI or Claude API key, or local Ollama.

Read-only queries, only when you allow them.

Ask your database. Get answers, not just SQL.

Chat with any SQL, MongoDB or Elasticsearch connection. The assistant reads the schema, runs read-only queries when you allow it and answers from the results.

Every query it suggests opens in your editor or runs read-only in the chat. Writes never run on their own.

Your credentials never leave your machine.

Your passwords stay in your OS keychain. No telemetry, analytics or cloud sync.
