Gurugram
Nextline Creative is an AI agent development company India businesses trust to ship production-ready systems, not chat demos. We build LLM agents that take real actions: calling your tools and APIs, retrieving facts from your own data with RAG, and handing off to a human when the request needs judgement. Our senior team works from our Gurugram HQ in Sector 10 and across Delhi NCR, then delivers remotely with weekly demos. Every build is scoped to a fixed price in INR before work starts, quoted up front with no surprise add-ons. We show you the guardrails and logs before anything goes live, so you can see exactly what the agent is allowed to do.
We start by mapping the jobs you want an agent to own, then scope the smallest version that is genuinely useful. A support agent might read your help docs, check an order, and raise a ticket when it cannot resolve something on its own. A sales agent might qualify a lead and book a slot. We define the tools the agent can call, the data it can read, and the actions it must never take alone. That scope becomes a fixed quote, agreed in INR before we write code.
Technically, the agent runs on a current LLM with function calling, so it chooses tools from a defined set rather than guessing. We ground answers in your own content using retrieval, which cuts hallucination and keeps responses tied to real sources. Every action runs behind guardrails: input validation, permission checks, rate limits, and a confirmation step before anything irreversible. We log each decision so you can audit what happened. The agent plugs into your stack over secure APIs, and we build the front end in Next.js and React when it needs a web interface.
You own everything at handover: the source code, prompts, infrastructure logins, and documentation. There is no lock-in, so another team can maintain the agent if you ever move on. We run kickoffs and reviews in person across Delhi NCR from our Gurugram HQ where that helps, then deliver remotely with weekly demos and WhatsApp access. This suits Indian businesses that want a real, maintainable agent rather than a wrapper around a chat box: support teams, operations, lead handling, and internal tools. If that is you, start at /contact or read our approach at /services/custom-web-development.
Look for honesty about what agents can and cannot do yet. We build on proven LLMs with function calling and retrieval, add guardrails and human handoff, and log every action so you can audit it. We scope a fixed price in INR before any code, hand over full ownership, and support you after launch. We will tell you when a simpler rules-based automation would do the job for less.
It depends on how many tools the agent connects to, how much data it reads, and how complex the actions are. A single-task agent costs far less than one that spans several systems. We quote a fixed price in INR after a short scoping call, with no surprise add-ons once work starts. See /pricing for how we structure tiers, and we can give you a clear figure once we understand the jobs you want the agent to own.
Guardrails. The agent can only call tools we explicitly allow, and sensitive or irreversible actions need a confirmation step or human approval. We validate inputs, set rate limits, and ground answers in your own data to reduce hallucination. Every decision is logged, so you can see what the agent did and why. If it is unsure, it hands off to a person rather than guessing. You stay in control of what it is permitted to do.
Yes. At handover you get the full source code, the prompts, the infrastructure logins, and documentation. There is no lock-in and no licence tied to us, so your own team or another developer can maintain and extend the agent later. We can stay on for support if you want, but that is your choice, not a condition. Owning everything also means you can move hosting or swap the model provider without asking our permission.
Sometimes, and we will say so. If your need is a fixed flow with clear rules, a simple automation or a form is cheaper and more predictable than an LLM agent. Agents earn their place when requests vary, when judgement is needed, or when the task spans several tools. We would rather scope the right tool than sell you an agent you do not need. Tell us the problem and we will recommend the honest option.
