# AI-Powered Website & App Development in Bangalore

Websites and apps with the AI built in rather than bolted on — search that understands a question, chat grounded in your own content, personalisation that survives a cold start, and the drudgery automated. Quoted as an increment on the build, because that is how it is actually bought.

## Short answer

Adding AI to a website costs **₹40,000** for CMS drafting, **₹60,000–₹1,50,000** for semantic search, **₹50,000–₹3,00,000** for a grounded assistant and up to **₹4,00,000** for real personalisation — on top of the normal build, plus ₹2,000–₹40,000 a month to run.

"AI-powered" is not a type of website. It is five specific features, and most sites want one of them.

## What "AI-powered" decomposes into

| Feature | What it does | Where it lives |
| --- | --- | --- |
| Search that understands the question | Semantic search over your pages, catalogue or documentation. A visitor typing "does this work outdoors in the rain" finds the IP-rating paragraph, which keyword search never would. | Site search, catalogue, docs |
| Chat grounded in your own content | A support or sales assistant answering from your pages and policies, with citations and a refusal when there is no source. Not a generic model with your logo on it. | Support, pre-sales, onboarding |
| Personalisation that survives a cold start | Ordering and copy that adapt to what someone has looked at — with a sane default for first-time visitors, which is where most personalisation projects quietly fail. | Homepage, category pages, app home |
| Content drafted where you edit it | Draft product descriptions, meta titles and alt text inside the CMS, with a human approving before anything publishes. Speed on the blank page, not autonomy. | CMS, catalogue, blog |
| The drudgery automated | Enquiry triage and routing, document and form extraction, summarising long submissions before a human reads them. Usually the highest-return item on this list and the least asked for. | Forms, back office, admin |
| An assistant inside the app | In-app help that can actually see the user's context — their order, their plan, their last error — instead of sending them to a help centre. | Mobile and web apps |

## Examples

| Site | What the AI does |
| --- | --- |
| An equipment catalogue | Two thousand SKUs where nobody knows the model numbers. Semantic search plus a spec-comparison assistant turns "something quiet enough for a clinic" into three results and a reason for each. |
| A services site | Pre-sales chat grounded in the service pages and price bands, qualifying the enquiry before it becomes a form submission — and refusing to quote, because quoting is the one thing it must not improvise. |
| A documentation site | Search across five years of guides, answering in a paragraph with the source linked. The measurable win is support tickets that never get raised. |
| A booking app | In-app assistant that can see the user's bookings and reschedule one, rather than explaining how to reschedule it. |

## Architecture

Three tiers. The browser holds the pages, chat widget, search box and app shell. Requests go down to your own server, which handles authentication, rate limiting, caching and prompt assembly. That layer calls the services tier — the LLM API, a vector store, your database and your CMS — and answers travel back up. The AI is never called directly from the browser: that keeps API keys out of the client, allows caching, and lets a scraper be rate-limited before it spends your model budget.

## Standard vs AI-powered

| Factor | Standard website | AI-powered website |
| --- | --- | --- |
| **Search** | Keyword matching. Misses anything phrased differently from your copy | Semantic — finds the right paragraph when the wording does not match at all |
| **Questions a visitor has** | Answered if they find the right page. Otherwise a contact form, then a wait | Answered in place, from your own content, with the source shown |
| **Out-of-hours enquiries** | Sit in an inbox until morning | Qualified and structured on arrival; the human reply starts from something useful |
| **Content production** | Every description, meta title and alt text written by hand | Drafted in the CMS, edited and approved by a person before publishing |
| **What it costs to run** | Hosting only — ₹500–₹5,000 a month | Hosting plus model usage — ₹2,000–₹40,000 a month, scaling with traffic |
| **What can go wrong** | A page is out of date | A confident wrong answer in front of a customer — which is why grounding, refusal and logging are not optional extras |
| **Effect on conversion** | The baseline you already measure | Fewer dead ends and faster answers. **I am not going to quote you an uplift percentage** — every published figure is vendor-supplied and unverifiable. Measure it on your own site with the analytics you already have |

*No conversion-uplift percentage is quoted because every published figure is vendor-supplied and has no control group. Instrument the feature and measure it on your own traffic.*

## Indicative pricing

Increments on top of the base build, not a package.

| AI feature | Added to the build | Monthly | Notes |
| --- | --- | --- | --- |
| **Semantic site search** | ₹60,000 – ₹1,50,000 | ₹1,500 – ₹8,000 | Indexing, embeddings, a relevance evaluation set. Scales with catalogue or page count |
| **Grounded chat assistant** | ₹50,000 – ₹3,00,000 | ₹2,000 – ₹25,000 | Same build as a standalone chatbot, sharing the site's content pipeline rather than duplicating it |
| **Personalisation / recommendations** | ₹1,00,000 – ₹4,00,000 | ₹2,000 – ₹15,000 | Needs real traffic to be worth doing. Below a few thousand sessions a month, a good default beats it |
| **AI drafting in the CMS** | ₹40,000 – ₹1,20,000 | ₹1,000 – ₹6,000 | Human approval before publish, always. Cheapest item here and often the most used |
| **Form and document automation** | ₹75,000 – ₹3,00,000 | ₹2,000 – ₹20,000 | Triage, extraction, routing. Usually the highest return and the least requested |
| **In-app assistant (mobile)** | ₹1,50,000 – ₹6,00,000 | ₹4,000 – ₹40,000 | Context-aware help inside a Flutter or React Native app, with the same guardrails as web |

## Frequently asked questions

### What does "AI-powered website" actually mean?

Concretely: search that understands a question, chat grounded in your own pages, personalised ordering, content drafted in the CMS, and enquiry or document handling automated. It is a set of features you choose from, not a category of website — and a site with none of them is not behind, it is just a site. If a vendor cannot name which of those five they are building, they are selling you a word.

### How much does it add to a normal website build?

**₹40,000 for CMS drafting at the small end, ₹60,000–₹1,50,000 for semantic search, up to ₹4,00,000 for real personalisation.** On a ₹80,000 business site that is a meaningful proportion, which is exactly why it should be one feature chosen deliberately rather than "add some AI". The base build is priced on the [website development](https://samuelmarndi.com/services/website-development/) page.

### Do I need AI on my website at all?

Often not, and I will say so. If you have eight pages and twenty visitors a day, a chat assistant has almost nothing to answer and almost nobody to answer it to — spend the money on the content and the speed instead. AI earns its place when there is volume, a catalogue, a document set, or a repetitive human step. Below that it is a running cost with a novelty attached.

### Will it slow the site down?

Not if it is built properly, because none of it should block the first paint. Search and chat load after the page is interactive and are usually lazy-loaded on interaction; server-side AI runs in an API route rather than in the render path. Where teams get burned is shipping a chat widget as a synchronous third-party script in the head — that costs real Core Web Vitals, and it is avoidable.

### What does it cost to run every month?

₹2,000–₹40,000 depending on traffic and which features are on. Semantic search is cheap per query and predictable; chat is the volatile line because each conversation carries context. Both are forecast from your real traffic and capped at the provider before launch, so a spike cannot become an invoice.

### Can you add AI to my existing site rather than rebuilding it?

Usually yes, and it is normally the better spend. Semantic search, a grounded assistant and CMS drafting can all be added to an existing WordPress, Next.js or Shopify site without touching the design. What sometimes forces a rebuild is content that only exists inside a page builder in a form nothing can read — in which case I will tell you before quoting, not after.

### Does it help SEO?

Indirectly, and not in the way it is usually pitched. AI-generated content published without editing is a liability rather than an asset. What genuinely helps is the second-order effect: better internal search surfaces content that was buried, and a grounded assistant produces a record of what people actually ask, which is the best keyword research you will ever get. Publishing unedited model output is the fastest way to undo both.

### Which stack do you build on?

Next.js and React for web, Flutter or React Native for mobile, with the AI layer behind your own API routes rather than called from the browser — which keeps the keys out of the client and lets you cache, rate-limit and swap models. Existing WordPress and Shopify sites are fine too; the AI sits alongside rather than replacing them.

### Who owns the prompts and the data?

You do, from the first commit, along with the code and the evaluation set. Model and hosting accounts are in your name and billed to you at cost. If you move to another developer the AI layer goes with the rest of the site — it is not a plugin of mine you would have to keep paying for.

### What if the AI gives a customer the wrong answer?

Design for it, because it will happen. Everything is grounded in retrieved content with the source shown, refuses when it has no source, hands off to a human, and logs every conversation so failures can be fixed rather than guessed at. The one hard rule I hold to: it never quotes a price or commits stock without a human in the loop. Those are obligations, and a model should not be creating obligations on your behalf.
