Many teams struggle with sharing sensitive datasets with cloud services, risking leaks, compliance violations, or accidental exposure. Even when using “secure” cloud platforms, you’re trusting third parties with your company’s intellectual property, financials, or research data.

We built Data.olllo to solve this problem: a local-first, fully offline data analysis tool that lets you explore, filter, and visualize massive datasets — 100GB+ CSV files included — without ever uploading a single row to the cloud.

Key features: • 100% offline: No cloud, no servers, no risk of third-party exposure. • GPU-accelerated: Analyze huge datasets quickly without Excel crashing. • No coding needed: A no-code interface that works for teams of mixed skill levels. • Privacy-first AI: Summarize, query, and visualize data locally using AI, without sending it anywhere. • Supports all major formats: CSV, Excel, HDF5, and more.

We realized that privacy isn’t just a checkbox — it’s a real constraint for many teams. Data.olllo makes it possible to work with large, complex datasets safely and efficiently, all on your local machine.

Over the last year, I’ve talked to hundreds of analysts, researchers, and business folks who all hit the same pain points: 1. “I’m not a programmer, and writing formulas or scripts slows me down.” Most data tools assume you’re comfortable writing formulas or Python scripts. We wanted something that could interpret plain language (“Show me all rows where revenue > 1M and region = APAC”) and just do it, without syntax errors. → https://olllo.top/no-coding-needed 2. “I can’t upload my sensitive data to cloud AI tools because of compliance and privacy concerns.” Many AI analysis tools run entirely in the cloud — which is a deal-breaker if you work in finance, healthcare, government, or just care about privacy. Our approach: everything runs locally. No data leaves your machine. → https://olllo.top/privacy-compliance 3. “I’m constantly frustrated by Excel crashing or freezing on large datasets.” Excel is great until you throw a few million rows at it. We’ve built a GPU-accelerated, memory-optimized backend so you can open multi-GB CSVs in seconds and work without freezes. → https://olllo.top/excel-crash-solution

The result is Data.olllo — a no-code, privacy-first, high-performance desktop app for data analysis and visualization. It runs on Windows & macOS, supports big data formats, and can generate charts/reports with AI — without ever sending your data to the cloud.

Would love feedback from the HN crowd — especially on: - What’s missing for you to trust an AI data tool? - Which integrations/formats are must-have for adoption?

Hi HN!

I’m the maker of Data.olllo – a no-code AI-powered tool for exploring and analyzing large datasets, now updated with new features and a smoother UX.

What’s new: • Live demo videos: See how to open and analyze large files quickly. • Works offline, with full local privacy – no data sent to the cloud. • Supports massive files – Excel, CSV, JSON, Parquet.

I built Data.olllo because I got tired of waiting for Excel or VS Code to open big files, and not everyone on my team codes in Python. Would love feedback, ideas, or criticism!

Thanks!
