How it works
Analyze CSV files with on-device AI. CSV rows and analysis content stay in your browser, and Free analysis needs no account.

After the initial on-device model download, ask questions in plain English and get charts and answers without sending analysis content to AskCSV.
AskCSV lets you analyze a CSV file by asking questions in plain English. The important part: the analysis happens inside your web browser, on your own device. Your CSV and analysis content are not sent to AskCSV or a cloud AI provider, no account is needed to analyze, and it's free to start.
Your analysis content stays on your device
Most data tools work by sending your file to a server in the cloud. We think that is the wrong trade-off — spreadsheets often contain sensitive information (customers, revenue, health, HR) that shouldn't be handed to anyone else.
AskCSV takes a different approach. When you pick a CSV file, it is opened directly in your browser. Every question, SQL query, result, and chart is produced locally on your machine. The app and AI model still use network downloads, but your CSV and analysis content are not transferred to AskCSV. Saved work stays in this browser until you delete it.
Ask in plain English
You don't need to know formulas, SQL, or any special syntax. Just type what you want to know:
- Drop in a CSV or TSV — click, drag, or paste delimited data. The first row is treated as your column headers.
- Prepare the model once — the first analysis downloads about 1.8 GB. Later visits can reuse the browser-cached model.
- Ask a question — for example, "What are my top 5 products by revenue?" or "Chart sales by month."
- Get an answer — once the model is ready, AskCSV understands your columns, runs the local analysis, and shows a table or chart.
Behind the scenes, an on-device AI reads the structure of your data and figures out how to answer your question. Because it runs locally, follow-ups do not require a cloud AI round-trip. The Free monthly analysis limit still applies.
Private by design, not by promise
The analysis boundary is enforced by the architecture: CSV or TSV rows, questions, SQL, results, charts, and chats stay in the browser. AskCSV can reduce cloud transfer risk for confidential work, but each organization is still responsible for evaluating its browser, device, access controls, and regulatory requirements.
Free to start
Free includes 10 successful analyses per month with no account required. Because the analysis runs on your own device, the file stays private while the monthly limit keeps Free sustainable. Pro is $5/month for unlimited successful analyses, conversation ZIP and chart PNG exports, deterministic two-file join or stack, and no ads.
