What does Nucleus Ai do?
Nucleus Ai is a business automation and software company in Noida, India that builds customer messaging and web systems: official WhatsApp Business API setup, RCS business messaging, AI chatbot automation, digital marketing, website development and custom SaaS products. The common thread is conversation — getting a business found, then answering, qualifying and selling automatically on the channels its customers already use.
What is the WhatsApp Business API, and how is it different from the WhatsApp Business app?
The WhatsApp Business API is Meta’s official platform for businesses that need to message at scale, and unlike the free WhatsApp Business app it has no device limit, supports multiple agents on one number, and allows automated template messages, catalogs and payment flows. The free app is designed for one person on one phone; the API is designed for a team, a CRM and thousands of conversations. Green-tick verification is only available through the API.
Do I need consent before sending WhatsApp, RCS or SMS messages in India?
Yes. Every commercial message in India requires documented prior consent, and the rules differ by channel: WhatsApp falls under Meta’s Business Messaging Policy, while RCS, SMS and commercial voice fall under TRAI’s Telecom Commercial Communications Customer Preference Regulations and the DLT framework. Consent must be specific, freely given and withdrawable — the Digital Personal Data Protection Act, 2023 also requires that withdrawing be as easy as opting in. Nucleus Ai collects consent per channel and honours STOP immediately.
Can you guarantee a number one ranking on Google?
No, and any agency that promises one is misleading you, because Google decides rankings and no third party controls its algorithms. What Nucleus Ai commits to is the process and the evidence: a technical audit, Core Web Vitals in the green, keyword-mapped content, schema markup, local search work and monthly reporting with numbers you can verify yourself in Google Search Console.
Who owns the code, content and accounts you build for me?
You do, completely. Repositories, designs, documentation, domains, hosting and analytics accounts are registered in your name and transferred to you on full payment, and that is written into the contract. Nucleus Ai does not hold client infrastructure as leverage — any competent developer can pick up the work if you leave.
How much does it cost?
Our packages and per-message rates are published in full on our Pricing page — WhatsApp Business API, chatbots, SMS, RCS, voice SMS, digital marketing and websites, all exclusive of GST. SaaS products and custom work outside a package are priced in a written statement of work before anything starts, so there are no open-ended hourly bills. Costs set by other companies, such as Meta’s message charges, advertising spend, DLT fees, domains and hosting, are separate from our fee.
