Your Own Private AI Brain.

Custom GPT Development Company in Mumbai

A law firm in Dadar needs a GPT that knows Indian case law and their own precedents. A manufacturing company in Marol needs one that knows their product catalogue and specifications. We build private GPTs that know exactly what your business knows, and nothing that it shouldn't.

Custom GPT Development Company in Mumbai

About Private AI Models in Mumbai

AI Trained Only on Your Data

Public ChatGPT is great for writing emails, but it doesn't know your company's SOPs, your specific product codes, or how your HR policies work. If an employee asks public AI a specific technical question about your manufacturing process in Marol, it will hallucinate.

We solve this by building a Custom GPT. We ingest your PDFs, spreadsheets, and historical data into a secure environment. The resulting AI acts as an expert consultant that sits on your intranet, ready to answer any employee's question instantly with 100% accuracy based purely on your documents.

Security is the main concern for businesses in Mumbai exploring AI. Working with our team, you get the assurance that your proprietary data is siloed through enterprise APIs, meaning OpenAI or any other provider cannot use your data to train their public models.

How Do We Work?

Our team members follow a step-by-step process to build a custom GPT. Here's the process

Client Communication

We start by understanding what your team keeps repeating or looking up, and who the assistant is meant to serve, staff, customers, or both.

Planning

We map out the GPT's instructions, knowledge sources and access rules, and share the plan with you before building begins.

GPT Configuration

We set up the assistant with your documents, tone guidelines and rules, and connect it to the knowledge sources it needs.

Performance and Bug Testing

We test the assistant with real questions your team or customers would actually ask, to check its answers stay accurate and on-brand.

Final Launch

Once testing is done, we roll out the assistant to your team or make it live for customers, depending on the use case.

Training & Rollout

We walk your team through how to use the assistant properly and how to flag answers that need correcting.

Maintenance

We stay available to update the assistant's knowledge and instructions as your documents, pricing or policies change.

Frequently Asked Question

Drop us a line and we will get back to you.

Will my proprietary data be used to train public ChatGPT?

No. We build Custom GPTs using secure enterprise APIs. Your data remains completely private and is never used to train OpenAI's public models.

What kind of data can I train the GPT on?

You can train it on PDFs, Word documents, Excel sheets, past emails, website content, or your proprietary knowledge base.

Can multiple employees use the Custom GPT?

Yes, we set up secure role-based access. Your entire team can log in and use the AI simultaneously without sharing the same session.

How is a Custom GPT different from standard ChatGPT?

Standard ChatGPT gives generic answers. A Custom GPT answers based specifically on your company's documents, policies, and tone of voice.

Can it integrate with our internal software?

Yes, we can deploy the Custom GPT via API directly into your intranet, CRM, or custom software applications.

What if we add new products or policies later?

We build an admin interface where you can easily upload new documents to continuously update the GPT's knowledge.
