Kaiwa DB Case Study
Query-generation tool that transforms natural language into secure and accurate database queries
Kaiwa DB - Case Study
Generate secure database queries
Kaiwa DB is a query-generation tool that transforms natural language into secure and accurate database queries — without exposing any data. Designed for developers, analysts, and product teams, it bridges the gap between non-technical questions and technical data structures. With Kaiwa, teams can query databases safely and efficiently using everyday language.
challenges
Challenges We Faced
As we began developing Kaiwa DB, we encountered several key challenges.
Understanding Without Data
We needed to enable natural language processing using only the database schema — never raw data.
Multi-Database Support
Building one engine that works seamlessly across MongoDB, PostgreSQL, MySQL, and others was a real challenge.
Transparent Costs
We wanted predictable usage, without the LLM cost spiral. Caching and credits became key.
Consistent Output
Every input should give the same output. No surprises, just clear and auditable queries.
Developer-First Integration
Kaiwa had to be easy to adopt, secure by design, and built with developers in mind.

No Data Leaves, Only Metadata Moves
To ensure maximum privacy, we built Kaiwa to run entirely on schema metadata — no actual data ever leaves the user’s infrastructure. We introduced a local agent that verifies access and executes queries within the client’s environment. Pipelines — our name for query blueprints — can be reviewed, reused, and versioned. Through strict naming, aliasing, and caching mechanisms, we achieve deterministic behavior and reduce repeated LLM costs.
Tames Messy Schemas
Even poorly structured databases become understandable thanks to alias mapping and schema translation.
Secure by Default
Your data never leaves your system — Kaiwa only sees the structure, not the content.
Works the Same Every Time
We avoid randomness in outputs, making it easier to test, review, and trust what’s being generated.
Simple Enough to Adopt, Powerful Enough to Scale
From quick tests to production use — Kaiwa grows with your needs, without adding problems.

Benefits of Kaiwa DB: The Value It Delivers Today
Natural Language Access to Data
Users can ask questions in plain language and get accurate database results without needing to understand SQL.
Complete Privacy and Control
Queries run entirely within the user’s environment — ensuring no sensitive data is exposed or shared.
Consistent and Auditable Outputs
Reusable pipelines and transparent logic help users trust and verify every query and result.
Faster Answers, No Bottlenecks
Users don’t need to wait for developers or BI teams to get the answers they need — saving time.
Developer Efficiency
Kaiwa reduces repetitive work by enabling others to self-serve their data needs — without compromising safety or structure.
Safe Democratization of Data
Teams can access insights without giving away raw access or breaking compliance boundaries.
Lower Costs & Predictable Spend
Query caching, reusable logic, and a credit-based model make it easy to control and forecast operational costs.
Future-Proof Query Infrastructure
Kaiwa helps build standardized, maintainable query pipelines that adapt to evolving schemas and real-world team needs.

Final Outcome
Kaiwa DB launched its public beta in 2025 with a clear mission: make database querying accessible, safe, and understandable. With early adopters already building custom integrations and internal chatbots, Kaiwa is becoming the go-to tool for secure, AI-powered query generation. We’re continuing to refine the product based on real user feedback — always with full transparency and a “no bullshit” philosophy.
