# ZenMagix

> AI engineering, automation and search visibility agency based in Mumbai, India.
> We build AI agents, retrieval systems, voice agents and workflow automation
> designed to run unattended in production.

ZenMagix Pvt Ltd began in blockchain infrastructure — wallets, exchange systems and
smart contracts — and moved its focus to AI engineering. That heritage informs how we
build: idempotent actions, auditable decisions, least-privilege tool scoping and
adversarial threat modelling.

## Writing

Engineering notes. Regulatory and measured claims name their source in the text
and link it at the foot of each article.

- [What the DPDP Act actually requires of an AI system](https://zenmagix.com/blog/dpdp-act-ai-systems): The obligations that survive contact with a vector store, a prompt log and a fine-tuned model — and the one that quietly makes fine-tuning on personal data a bad idea.
- [RBI data residency and calling an external LLM](https://zenmagix.com/blog/rbi-data-residency-external-llm): Payment data, the 24-hour rule, the outsourcing direction’s right-to-audit clause, and why redaction at the boundary is a design problem rather than a regex.
- [Why voice agents fail on Hindi-English code-switching](https://zenmagix.com/blog/voice-agents-hindi-english-code-switching): Where the transcript actually breaks, why word error rate is the wrong target, and what has to change in endpointing, normalisation and evaluation.
- [Why your RAG system gives wrong answers, in order of likelihood](https://zenmagix.com/blog/why-rag-gives-wrong-answers): Eight causes, ranked, each with the cheapest test that distinguishes it from the one above — ending, reluctantly, at model choice.
- [How to evaluate a RAG system before you trust it in production](https://zenmagix.com/blog/how-to-evaluate-a-rag-system): What goes in a golden set, which metrics to keep apart, how to check an LLM judge is worth trusting, and the ways an evaluation harness quietly stops being valid.
- [The gap between an AI demo and something that runs unattended](https://zenmagix.com/blog/ai-demo-to-unattended-production): Retries that send the email twice, agents with more authority than anyone intended, and the alerting signals that actually catch a failing agent.

## Where we work

Location, cost and sector pages. Each argues something the others cannot: the
Mumbai page is about proximity, the India page about jurisdiction, and each
sector page about the constraint that actually decides the build in that sector.

- [AI development in India](https://zenmagix.com/ai-development-company-india): building AI in India: DPDP, RBI, CERT-In, India Stack and what outsourcing usually gets wrong
- [Mumbai office](https://zenmagix.com/ai-development-company-mumbai): the Mumbai practice: Chakala office, the industries that cluster here, working in three languages at once
- [AI development cost](https://zenmagix.com/ai-development-cost-india): what moves the price of an AI build in India — integration surface, data quality, accuracy bar — and what an Indian rate does not buy
- [AI for BFSI](https://zenmagix.com/ai-for-banking-financial-services): retrieval with provenance and refusal for banks, insurers and NBFCs, and what the RBI outsourcing direction requires of a vendor
- [AI for logistics](https://zenmagix.com/ai-for-logistics-supply-chain): document extraction for freight and customs, scored per field rather than on average, and the exception queue that has to come with it
- [AI for media](https://zenmagix.com/ai-for-media-advertising): content operations, version identity, localisation and creative variants — and the arithmetic that limits how many variants are worth testing
