# AI engineering services > Mirai Minds offers five AI engineering services: AI agents and automation, voice AI agents, WhatsApp AI agents, custom LLM and document AI, and computer vision. Each is delivered end to end — scoping, evaluation, build, launch with human review and running it afterwards — and most builds ship in two to eight weeks. ## Start from the job, not the model Every engagement starts with the work the system has to do: the documents it reads, the calls it takes, the actions it may and may not take, and what happens when it is unsure. The model comes later, and it is usually the easiest part to change. ## Build the test set before the system In the first week we collect real examples — documents, recordings, chats, photos — and agree what a correct answer looks like. That set tells us which model is good enough, catches regressions when prompts change, and keeps running after launch. Numbers we quote come from it. ## Keep a person in the loop until the numbers say otherwise Extraction gets a reviewer, voice agents get a live handoff, and agents that act in your software get limits on what they may do alone. We relax those checks only when the error rate on real traffic says it is safe. ## Choose the simplest stack that holds up A hosted platform is often the fastest way to a pilot; a custom build pays off at volume, with strict data rules or with Indian languages. We model running costs on your expected volume before you commit, and we say when a smaller or cheaper model is enough. - [AI agents and automation](https://www.miraiminds.co/services/ai-agents.md) — Agents that read, decide and act inside your tools, with every tool call logged and a person approving the risky ones. - [Voice AI agents](https://www.miraiminds.co/services/voice-ai-agents.md) — Phone agents that answer, qualify and follow up in English or Hindi, and bring in a person when the caller needs one. - [WhatsApp AI agents](https://www.miraiminds.co/services/whatsapp-ai-agents.md) — WhatsApp agents that remember each customer, answer from your documents and let your team step in from an inbox. - [Custom LLM and document AI](https://www.miraiminds.co/services/custom-llm-development.md) — Language models grounded in your documents and data, measured on your own test set, with people reviewing what matters. - [Computer vision](https://www.miraiminds.co/services/computer-vision.md) — Vision models that find faces and products, cut out backgrounds and edit photos, fast enough for a queue of real customers. ## Frequently asked questions ### Can one system combine voice, WhatsApp and an agent? Yes, and it often should. On iKoMatch, founders onboard over WhatsApp and an AI phone call fills in whatever the chat missed; both feed the same founder profile and the same matching engine. We design the core once and add channels on top. ### How do you decide what to build first? We start from the job that costs the most time or money today and the data that already exists for it. The first release does one job end to end, with a person reviewing the output, so you see value in weeks rather than after a long platform project. ### Do you only build new systems, or improve existing ones too? Both. Some of our work adds AI stages to software a client already runs; the Photo Experience platform, for example, predates us. We read the existing code and data first, then decide what to keep, fix or replace. ### What if AI is the wrong tool for our problem? Then we say so on the first call. Some problems are better solved with rules, a better form or a spreadsheet, and a model would only add cost and failure modes. --- Canonical: https://www.miraiminds.co/services Last updated: 2026-09-23 Publisher: Mirai Minds LLP, 906 Sarthana Business Hub, Nana Varachha, Surat, Gujarat 395013, India. hello@miraiminds.co
