What Anthrena Desk does

Four things no cloud BI
can honestly promise you.

Speed. Privacy. Intelligence. Ownership. Each one built into the architecture, not the pricing page.

01 · Velar-N AI

Ask your data. Get an answer. On your machine.

Type a question in plain English. Velar-N — a small model running entirely on-device — translates it into AQL, Fluxor executes it, you see the answer. No cloud API call. No data leaving your machine.

02 · Fluxor Engine

Rust-speed compute. Browser-weight delivery.

Fluxor is a Rust analytics kernel compiled to WebAssembly, running Polars DataFrames inside your app process. Sub-second aggregations with no server and no query queue.

03 · AnthrenaPivot

Pivot tables that never freeze. Ever.

Streaming, cancellable computation means you can drag-and-drop dimensions while Fluxor recalculates in the background — multi-level grouping and drill-down without a spinner.

04 · ML Model Builder

Train models on your data. No Python.

Select a target column, choose a task — classify, cluster, forecast — and train locally. SHAP values explain every prediction. Apply back to new data in one click.

Under the hood

Four layers. Zero cloud.
One machine — yours.

Every component is designed to run disconnected. This is not a "works offline" checkbox. It is the design.
