Unlike traditional tools, ZenQuery combines speed, cost-effectiveness, power, and simplicity in one elegant solution.
Tired of Excel and other similar tools choking on files with just 100K rows and freezing your computer? ZenQuery is built for speed—effortlessly handling tens of millions of rows without breaking a sweat. Work at scale without the lag.
Tools like ChatGPT can burn through hundreds of dollars just to answer a few hundred questions on modest-sized files (just around 1 MB). In case your files are over a few dozen MBs? You're out of luck — they simply can't handle it because of their context limits. ZenQuery is built for real-world data, without the cost or limits.
Forget the hassle of setting up databases, wrestling with table schemas, loading data, and hand-crafting SQL for every little question. ZenQuery removes all that friction — just drop in your files and ask. No setup, no syntax, just answers.
Scripting in Python or Pandas just to filter or summarize a CSV? That’s many tens of minutes lost to boilerplate, debugging, and runtime errors. ZenQuery gives you instant answers — no coding, no Jupyter notebooks, no imports.
Manually scanning rows and columns in Excel or writing repetitive filters in scripts? ZenQuery turns exploration into a conversation. Just ask what you want to know, and get smart, contextual answers in seconds.
Concerned about data privacy when uploading sensitive files to the cloud? ZenQuery runs locally, keeping your data secure and compliant while still delivering powerful query capabilities.

Yes, absolutely. By default, only the first 3 rows of your data are shared with the LLM for analysis. You can adjust this to zero in settings if needed. Your files never leave your computer.
ZenQuery can easily handle files with millions of rows and multi-GB sizes. Unlike Excel which slows down with large files, ZenQuery processes massive datasets in under 5 seconds.
Not at all! ZenQuery is designed for non-technical users. Simply ask questions in plain English like "What are my top 10 customers by revenue?" and get instant answers. If you are a data analyst, use this to quickly get auto-generated sql queries.
