ERP and CRM
A search box that understands business questions inside your system.
ZULENY NL→SQL
Your users ask. Your database answers.
Turns questions in English, Spanish or Portuguese into safe, parameterized SQL for SQL Server, PostgreSQL, MySQL and SQLite. No LLMs, no data leaving your server, in milliseconds.
FEATURES
Everything you need to talk to your data
An engine built for commercial products: fast, explainable and easy to embed in any .NET application.
Private by design
Runs inside your application. Neither the schema nor the data ever leaves your infrastructure.
Deterministic and auditable
The same question always yields the same SQL, with a step-by-step interpretation and a confidence score.
Secure by default
Read-only, parameterized queries. No string-concatenated SQL, validated against the real schema.
4 SQL dialects
One interpretation, four outputs: TOP or LIMIT, quoting, date functions and paging right for each engine.
Multilingual
English, Spanish and Portuguese with auto-detection, synonyms and your business vocabulary.
Natural dates
Semesters, quarters, weeks, ranges and relative expressions, such as "orders year to date".
Advanced analytics
Percentages, growth, running totals, rankings, top N per group, Pareto, median, pivots and budget vs actual.
Forecasts
History comes from SQL and the forecast is computed in .NET, with method and notes explained.
In milliseconds
About 15 ms per typical translation, with no model training, no GPUs and no external services.
HOW IT WORKS
From question to result in three steps
Embed Zuleny NL→SQL in minutes in your .NET 8 or .NET Standard 2.0 application, from your UI, a chatbot or a report builder.
WHO IT'S FOR
Built for the software your customers already use
Dashboards and reports
Charts, tables and ad-hoc reports without waiting for IT to write the query.
Chatbots and assistants
Exact answers from real data, without hallucinations.
WHY NOT AN LLM?
Cost, privacy and predictability for your product
Unlike LLM-based text-to-SQL, your data and schema never leave your server, you don't pay per token and the same question always yields the same SQL, validated against the schema.
COMPATIBILITY
Drop-in replacement for NReco.Data and NReco.NLQuery
Written from scratch (clean-room) with the same public API. Migrate your solution with a script, no rewrite needed.
Try it with your own questions
The demo runs on a sample database: type anything and see the SQL, the explanation and the result instantly.
