About SifarData
Sifar Data is a browser-based AI data analyst that lets you query very large CSV or Excel files (up to ~10 million rows / ~5 GB) without uploading them to a server. Files are parsed and analyzed locally (chunked parsing to keep memory flat), preserving privacy — only column names are visible to the service. Ask questions in plain English and get instant answers. No sign-up or credit card required to try; performance depends on your laptop's RAM.
