About

QSTM Ai Systems Private Limited

AI you own outright, not AI you rent by the token.

QSTM Ai Systems Private Limited is the legal entity behind the CustomAi.in brand: a Chennai-based bespoke AI studio building sovereign, client-owned AI systems across three products — Salient 1.0, Umpire and Verity.

Salient 1.0 runs on the client’s own weights, fine-tuned on their own corpus, with no OpenAI, Anthropic or Google in the loop and no outbound calls at runtime. That distinction — owned, not rented — runs through everything we build.

Salient 1.0 reasons, Umpire checks every action before it happens, and Verity puts both to work across the apps a company already runs.

The master tagline

Sovereign AI. Governed. Custom-orchestrated.

One line, one word per product: Sovereign is Salient 1.0, Governed is Umpire, Custom-orchestrated is Verity.
