Can I use Tawk.to or Intercom instead of Sift?

You can use them, but they solve a different problem. Tawk.to and Intercom are customer support tools — they let you chat with visitors in real time or set up basic scripted bots. Neither understands property-specific concepts like chain status, Decision in Principle, Help to Buy, or stamp duty thresholds. Sift is built specifically for UK estate agent lead qualification: it identifies serious buyers using UK-specific signals and scores leads 24/7 without a human agent on the other end.

What does Sift do that a generic chatbot cannot?

Three things: qualification, scoring, and automation. A generic chatbot asks for a name and email. Sift asks about chain status, Decision in Principle, budget, property type, timeline, and buyer scheme eligibility — the signals UK estate agents actually need. It then scores the lead (Hot / Warm / Cold), matches them to your listings, and books a viewing from your real calendar. All of this happens 24/7 without any staff involvement.

How is Sift different from a scripted chatbot I build myself?

A scripted chatbot follows a fixed decision tree — if the buyer's answer doesn't match a branch, the conversation breaks. Sift uses a large language model that understands natural language, follows up on vague answers, handles unexpected responses, and maintains a coherent qualification conversation across multiple turns. It also surfaces property matches from your listings mid-conversation, which a scripted bot cannot do.

Do generic chatbots handle UK GDPR consent?

Most do not have a built-in UK GDPR consent gate. They may have a general privacy policy link, but they typically collect names and emails before consent is given. Sift captures ICO-compliant consent before any personal data is stored, with a full consent record timestamped and auditable.

What does Sift cost compared to Intercom or Tawk.to?

Tawk.to is free (but requires a human agent or limited scripted bots). Intercom starts at around £69/month for basic features, rising steeply with contact volume — a busy estate agency handling 500 contacts/month often pays £200–400/month for Intercom. Sift starts at £149/month and includes all three channels (web chat, SMS, email), full AI qualification, lead scoring, property matching, and viewing booking. No per-seat pricing for agents monitoring leads.

Sift vs generic chatbots
for estate agents

Tawk.to, Intercom, Tidio, and LiveChat are customer support tools. They collect a name and email. Sift qualifies buyers — chain status, DIP, budget, schemes — then scores and books them. Built for one job: UK estate agent lead qualification.

The problem with a generic chatbot on an estate agency website

A buyer lands on your site at 9pm Saturday. They click the chat widget. The generic bot asks: "Hi there! What's your name and email?"

They give it. The bot says: "Thanks! Someone from our team will be in touch."

Monday morning, your negotiator calls back. The buyer has already booked a viewing with the agent who called them Sunday evening. The chatbot captured a contact detail. It didn't qualify anyone.

Qualification means knowing: are they chain-free? Do they have a Decision in Principle? What's their real budget? Are they buying or renting? How soon? These are the questions that separate a serious buyer from a browser — and a generic chatbot doesn't ask any of them.

Generic chatbots Customer support tools

Intercom, Tawk.to, Tidio, LiveChat, and Freshchat are built for e-commerce and SaaS customer support. They let your team chat with visitors in real time, or run scripted bots that collect contact details. None understand UK property concepts.

✗ No knowledge of chain status, DIP, or Help to Buy
✗ Scripted bots break when buyers give unexpected answers
✗ No lead scoring — just contact capture
✗ No property matching — can't suggest listings
✗ No viewing booking integration
✗ Usually requires a human agent out of hours or goes dark
~ GDPR consent varies by tool and config

The same buyer. Two different conversations.

Generic chatbot (Tawk.to / Tidio / scripted bot)

Bot: Hi there! Welcome to Smith & Jones Estate Agents. What can I help you with today?

Buyer: I saw a 3-bed in Harrogate on Rightmove, wanted to arrange a viewing

Bot: Great! Can I take your name and email address?

Buyer: James Clarke, james@email.com

Bot: Thanks James! Someone from our team will be in touch soon.

Result Monday morning: Agent knows James's email. Doesn't know if James is chain-free, has a DIP, what his real budget is, or if he's already viewed 10 other properties. The "hot lead" call often reaches a cold buyer.

Sift — AI lead qualification

Sift: Hi, I'm Sift — the AI assistant for Smith & Jones. I can help with viewings and property questions any time. Before I take your details, quick question: are you currently in a chain, or would you be chain-free?

Buyer: Chain-free, sold subject to contract last month

Sift: That's great position to be in. Do you have a Decision in Principle from a lender, or are you a cash buyer?

Buyer: Got a DIP from Halifax, budget up to £380k

Sift: I found 3 properties that match your budget and the Harrogate area. The 4-bed semi at £349k has availability Tuesday 6pm or Saturday 10am — which works better?

Result Monday morning: James's lead is scored Hot. Chain-free, DIP confirmed, £380k budget. Viewing already booked for Tuesday. Agent calls to confirm — that's it.

The hidden cost of a "free" chatbot

What Tawk.to costs

£67k

Estimated annual revenue lost to unqualified / missed leads per agency

£1,788

Sift Starter annual cost (£149 × 12)

Tawk.to and free chatbots don't cost money — they cost leads. Every buyer who gets an empty chat widget at 9pm on a Sunday, fills in a contact form and gets an auto-reply, and books with a competitor before Monday morning is worth £4,500 in commission at typical UK rates. Sift at £149/month pays for itself the first time it captures a buyer your team would have missed.

Which tool fits your situation

→

Use Sift if you want to qualify buyers 24/7 with zero staff involvement

You're an independent estate agency, 1–20 branches. You receive 30+ website enquiries per month. You lose enquiries on evenings and weekends because nobody's answering. You want to know if a buyer is proceedable before you pick up the phone — chain status, DIP, real budget. Sift handles all of this automatically.

→

Use a generic chatbot if your team can staff it in real time

If you have a dedicated front-of-house team answering chats during office hours and don't need out-of-hours AI, tools like Intercom or LiveChat work well for their core use case. They won't qualify leads for you, but they'll connect buyers to your team when your team is available.

→

Use both if you want live chat support and 24/7 AI qualification

Some agencies run a live chat tool during working hours and Sift after hours. This works, but adds cost and complexity. Sift covers all hours including business hours — so most agencies find they don't need a second tool.

Frequently asked questions

You can use them, but they solve a different problem. Tawk.to and Intercom are customer support tools — they let you chat with visitors or set up basic scripted bots. Neither understands chain status, Decision in Principle, Help to Buy, or stamp duty. Sift is built specifically for UK estate agent lead qualification: it identifies serious buyers using UK-specific signals and scores them 24/7 without a human agent.

Three things: qualification, scoring, and automation. A generic chatbot asks for a name and email. Sift asks about chain status, Decision in Principle, budget, property type, timeline, and buyer scheme eligibility. It then scores the lead Hot / Warm / Cold, matches them to your listings, and books a viewing from your real calendar — all in one conversation, at any hour.

A scripted bot follows a fixed decision tree. If the buyer says something unexpected — "we're waiting on probate" or "part-exchange" — the script breaks. Sift uses a large language model that understands natural language, follows up on vague answers, and handles edge cases. It also surfaces property matches from your listings mid-conversation, which a scripted bot cannot do.

Most do not have a built-in UK GDPR consent gate. They may show a privacy policy link, but typically collect names and emails before consent is captured. Sift captures ICO-compliant consent before any personal data is stored, with a timestamped, auditable consent record per lead.

Tawk.to is free but requires a human agent or runs scripted bots with limited logic. Intercom starts around £69/month and rises steeply with contact volume — a busy agency often pays £200–400/month. Sift starts at £149/month and includes all three channels (web chat, SMS, email), full AI qualification, lead scoring, property matching, and viewing booking with no per-seat pricing.

Yes. You remove the Tawk.to script tag and replace it with Sift's one-line script tag. Takes about 10 minutes. Most agencies doing this report immediate improvement in lead quality because Sift asks qualification questions instead of just capturing contact details.
