About Snowflake Cortex
Snowflake Cortex is Snowflake’s built-in AI and text-to-SQL layer. You create a view, pick tables, and add a prompt, with broader rollout managed via Snowflake Intelligence.
Why choose nao over Snowflake Cortex?
- Works for your whole company, not limited to users with Snowflake credentials
- Fully flexible context options, not limited to warehouse and Snowflake semantics
- Built-in evaluation framework to measure and improve answer accuracy
Our review of Snowflake Cortex agent
Snowflake Cortex is very easy to turn on if your Snowflake is on the right cloud: you create a semantic view, add tables, and write a prompt, and you are up and running. The semantics live entirely inside Snowflake and are disconnected from your existing dbt or external semantic layer, and Cortex only works for users with Snowflake accounts, with broader rollout done via Snowflake Intelligence and SQL configuration. There is no native evaluation framework, so reliability remains hard to measure.

| Context flexibility | File system context | Limited options, prompt and table sampling in Snowflake only |
| Monitoring | Audit logs, usage tracking, feedback loop | Snowflake query history only |
| Cost | Open source / self-hosted | Snowflake credits (metered) |
