Frequently Asked Questions about Nao
Does nao support data warehouses other than BigQuery?
The documentation mentions BigQuery specifically, but nao is built to support multiple databases. Check the repository or documentation for the current list of supported warehouses before connecting your primary data source.
Can I deploy nao to Slack, Teams, and other chat platforms at the same time?
Yes. nao supports multi-channel deployment across Slack, Teams, WhatsApp, Telegram, and Claude, so you can run the same analytics agent in multiple team communication tools simultaneously.
How does nao test whether its context actually improves query accuracy?
Nao includes context reliability testing and unit testing for question-to-SQL accuracy, so you can measure whether your organized schemas, metrics, and documentation are actually helping the agent return correct results. This testing happens before you deploy to your team.
Can I run nao with my own LLM instead of relying on Anthropic's Claude?
Nao supports self-hosting with your own LLM keys, giving you control over which model processes queries and where your data context lives. This setup is intended for teams with data governance requirements.
