An AI assistant for archaicinfotech.com
A chat window on every page that answers visitors' questions about our services, prices and past work, points them to the right case study, and turns the conversation into an order.
Verdict: feasible. Ready in about 3 weeks.Six jobs the assistant does on our site
Answers service questions
Explains each of our 9 services in plain words, using the same content as our service pages.
Quotes starting prices
Gives package prices and timelines only from our approved price list. Anything outside it gets "our team will quote you".
Shows matching past work
Picks the closest of our 16 case studies (Perfect Stay for hotels, Perfect Builders for real estate) and links to it.
Captures the lead
Collects name, phone and requirement, then sends it to our inbox the same way the order form does.
Hands over to a human
One tap opens WhatsApp on +91 93426 44454 with the chat summary already typed.
Speaks the visitor's language
Replies in English or Tamil, whichever the visitor writes in.
Four parts, one of them new
Our website is static HTML, so it can't safely hold the AI key itself. We add one small piece in the middle, a "proxy". It keeps the key secret and limits how the assistant is used. Everything else either exists already or is a single script tag.
Chat widget
A small JavaScript bubble at the bottom corner, in our brand colours.
Secure proxy
A Cloudflare Worker (free tier) or a PHP file on our hosting. It holds the API key and enforces rate limits.
Claude API
Writes each reply, using only our knowledge sheet as its source.
Knowledge sheet
Services, packages, FAQs and 16 projects. This already exists as site_data.py.
Lead email
Sent through FormSubmit, the same route as our order form.
WhatsApp handover
A prefilled chat to our number.
Order page prefill
Opens order.html with the service and package already ticked.
Three ways to add chat, and which one we recommend
| Option | How it answers | Monthly cost | Build effort | Verdict |
|---|---|---|---|---|
| A · FAQ bot Buttons and fixed answers | Only the questions we pre-write. Anything else gets "contact us". | ₹0 | 3–4 days | Feels robotic |
| B · Our own AI assistant Claude API + proxy | Understands free-text questions and answers from our own content. Links our real projects. | ₹500–₹6,600 | ~3 weeks | Recommended |
| C · Third-party widget Tawk.to, Tidio, Crisp | Tawk.to is free but only offers live chat with a human. AI answers are a paid add-on, with their branding and limited control. | ₹0–₹3,000+ | 1 day | Less control |
Why B
"AI chatbots" is already one of our listed services. Building our own gives us a live demo to show clients, and the same setup can be resold. A booking assistant for Perfect Stay or a site-visit assistant for Perfect Builders would reuse 80% of the work.
What it costs to run each month
We pay the AI provider per word processed. The model is our choice. A stronger model writes better answers, and a lighter one costs a fraction. The table assumes 5,000 replies a month, roughly 1,000 visitors chatting 5 messages each.
| Model | Answer quality | Per reply | Per month | ≈ ₹ / month |
|---|---|---|---|---|
| Claude Opus 5.5 | Best judgement, most natural replies | $0.016 | $78 | ₹6,600 |
| Claude Sonnet 5.5 | Very good, a little faster | $0.009 | $43 | ₹3,650 |
| Claude Haiku 5.5 | Good for straightforward FAQs | $0.001 | $6 | ₹500 |
How we estimated it: each reply reads an ~8,000-token knowledge sheet (cached after the first use) plus ~1,500 tokens of conversation, and writes ~400 tokens. Prices are list API rates as of October 2026: Opus 5.5 $4 / $20, Sonnet 5.5 $2 / $10 and Haiku 5.5 $0.10 / $0.50 per million input / output tokens, with cached reads at $0.20. Converted at ₹85 = $1. Hosting the proxy on Cloudflare's free tier (100,000 requests a day) adds nothing. We can set a hard monthly spend cap in the API console so the bill can never surprise us.

What could go wrong, and how we prevent it
It may only quote from the approved price list. For anything custom it says "our team will send a fixed quote". It never confirms discounts or deadlines.
The key lives only on the proxy, never in the website's code. The proxy accepts requests from archaicinfotech.com only.
Per-visitor message limits, a maximum message length and a hard monthly spend cap set in the API console.
It politely steers back to our services, and hands over to WhatsApp when unsure.
No chat history is stored on our side. Personal details are sent only when the visitor asks to be contacted.
What we need to decide
- Create an Anthropic API account and add billing
- Choose the model: Opus 5.5, Sonnet 5.5 or Haiku 5.5
- Pick where the proxy runs: free Cloudflare account, or our PHP hosting
- Confirm the final price list and which packages show prices
- Name the assistant and approve its tone
Our recommendation
Build option B on a Cloudflare Worker, with a ₹5,000 monthly spend cap. Run it on our own site for a month, read the real conversations, then offer it to Perfect Stay and Perfect Builders as a paid add-on.
