Frequently asked questions

Upload a CSV file and ask questions in plain English. UseClevr's AI reads your table headers and data types, runs verified calculations (sum, average, top-N, group-by, etc.), and returns both the computed result and a plain-language explanation.

No. UseClevr translates natural language into structured queries and deterministic calculations. You only need to understand your own data — the platform handles the rest.

Go to the Datasets page from the sidebar and click "Upload dataset". Supported format is CSV (up to 50 MB per file). Once uploaded, the column headers are parsed and the dataset is ready for analysis.

CSV files are fully supported for upload, analysis, and report generation. We recommend UTF-8 encoded CSVs with a header row.

Most users are analysing their first dataset within five minutes. Create an account, upload a CSV, and type your first question — no configuration required.

UseClevr uses Google Gemini via the AI SDK for cloud analysis. Hybrid AI Lite runs a local model in your browser for sensitive datasets — your data never leaves your device during local analysis.

Any question your structured data can answer: totals, averages, top-N rankings, group-by summaries, comparisons over time, trend analysis, and more. The AI will confirm if a question cannot be answered with the available columns.

Ask one clear question, name the dataset or metric when it matters, and ask for the direct result first. Add context such as period, region, product, or customer segment when you need a focused answer.
