[Talk to an AI engineer](https://zeroic.in/book?service=mvp) [See the work](https://zeroic.in/work) **Starting at** $12,000 **Timeline** 5-6 weeks **Products shipped** 40+ ## Where most chatbots are A chatbot is only as good as what it knows and what it's allowed to say. We ground answers in your own content, test them on real questions before launch and keep them inside clear limits. Our team built the chat and voice coaching in an AI product for employees, end to end, in 6 weeks. Answers sound right but are wrong → Answers grounded in your own content It knows nothing about your product → Connected to your product and data Users can talk it into anything → Clear limits on what it will say Nobody checks what it actually says → Conversations reviewed and improved ## What goes into a chatbot people trust ### Grounded in your content Answers come from your docs, help centre or data, with the source passed to the model. When nothing relevant comes back, it says so instead of making something up. ### Part of the product A chatbot works best inside your product, next to the screens and data users already have, not in a widget bolted on later. We build it into the app, on its accounts and data. ### Privacy decided early Decide early what the bot stores, who can see it and what never leaves the chat. Managers can see patterns across conversations without anyone's own words being exposed. ### Tested before launch We test on the real questions your users ask, including the awkward ones, and track how often answers are right, so it earns the trust of your users from the very first conversation. ## How it works 1. 01 ### Scope the first version (week 1) On free calls we agree what the chatbot must answer and fix scope and price before you pay. Week 1: data and tests. 2. 02 ### Build and test (weeks 2-5) Retrieval, chat and guardrails, tested on real questions every week. The engineer building it is the one on your calls. 3. 03 ### Launch and support (week 6 on) We ship to production, hand over the code, docs and credentials, and stay on for 6 weeks of support as real chats come in.

A first version starts at $12,000 as a fixed-price MVP Sprint, live in 5-6 weeks. We agree scope and price before you pay anything. Adding a chatbot to a live product can also run on a retainer, from $4,000 a month. When is a custom chatbot worth it? When it needs your product data, your own logic or privacy rules that hosted tools cannot meet. That is where a custom build pays for itself. How do you stop it making things up? By answering from retrieved content, telling it to say when it does not know, and testing on real questions before launch. We keep checking quality after launch too. Which AI models do you use? OpenAI, Anthropic Claude or open models, chosen per task by quality, cost and speed. We build it so the model can be swapped later. Do we own everything you build? Yes, 100%. You own the code, prompts, data pipelines, docs and credentials. ## Hear from us within 24 hours. **Prashant and Khushi** Partners @ Zeroic Want a chatbot that knows your product?
