How It Works

Three steps. Zero complexity.

STEP 01

You ask

Type a question in natural language. No syntax. No training.

STEP 02

We parse

A deterministic engine matches your words to schema metadata and generates SQL. No LLM. Instant.

STEP 03

Data answers

SQL executes, the right visualization is selected, and you see data with an intelligent summary.

Architecture

Why deterministic, not generative?

Every NL→SQL product today sends your schema to an LLM. Kaveon doesn't.

0%
hallucination rate

Zero Hallucination

100% predictable SQL generation with schema boundary enforcement. Every query maps directly to your metadata — no guessing, no made-up columns, no wrong JOINs.

<10ms
parse time

Sub-10ms Latency

Compiled rule-based parsing returns SQL in single-digit milliseconds. No token generation pipeline, no API round-trip, no queue. Your dashboard loads before you blink.

$0
per query

Zero Token Cost & Total Privacy

No data leaves your network. No schema sent to third-party model providers. No per-query API costs. Run on your infrastructure with complete data sovereignty.

Adaptive Context Routing

Every question is routed through a per-element staleness scorer that reads database modification counters — not re-queries. Fresh data answers instantly from context. Stale elements trigger targeted live queries and self-heal for next time.

Per-element validity scoring from DBMS statistics
Zero-query answers from profiled column distributions
Self-healing feedback loop after each live query
No LLM, no API keys, no latency
Question

Everything you need

One platform. Ask questions, build charts, create dashboards, write SQL.

Core

Conversational Data Querying

Type questions in plain English. A template-based NL→SQL engine parses your words, matches schema metadata, generates SQL, and renders the answer as an interactive chart.

37 Chart Types

Bar, line, pie, heatmap, treemap, scatter, funnel, gauge, world map, 3D globe. All dark-mode aware.
