Ask your spreadsheet in plain English, get charts
Ask about your spreadsheet the way you would ask a colleague, and get a chart or a number back.
Every chart shows the query that produced it, so totals, shares and averages can be checked.
The file is opened and queried in your tab and is never uploaded to the service.
Each question builds on the last, keeping the context of your file and earlier answers.

Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.

Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
