Rex AI Prospecting finds and outbounds to leads. But when inbound enquiries arrive — from Rightmove, Zoopla, your website — there's no qualification layer. Sift fills that gap: a 24/7 AI agent that qualifies every buyer before they reach your negotiators.
Rex AI Prospecting identifies vendors and buyers to target — it's a powerful outbound tool. But the moment a lead arrives inbound (Rightmove, Zoopla, direct), Rex expects a human to pick it up. That's the gap Sift closes.

Five steps from enquiry to a qualified lead in your Sift dashboard
Add one script tag to your agency website. The widget appears as a chat button — branded to your agency. No developer needed, setup in 10 minutes.
Sift greets the buyer and begins qualification — naturally, conversationally. It covers chain status, DIP/AIP, cash buyer, government scheme eligibility, budget, and timeline.
The AI handles objections, probes for detail, and ends with a booking invitation to speak with a negotiator. Typically under 2 minutes per lead.
Full transcript, GDPR consent, lead score, and contact details — accessible in the Sift dashboard. Export via CSV at any time (every plan), or route leads into Rex via Zapier, an outbound webhook, or the REST API on Growth/Scale. A native Rex integration is on the roadmap.
Negotiators call hot leads first — they already know who's proceedable, who's mortgage-ready, and who's just browsing. Conversations close faster.
Agencies using Sift report negotiators spending 40% less time on leads that were never going to proceed — time redirected to viewings and offers.
Every conversation captures structured data your negotiators actually need — available in the Sift dashboard, via CSV export (every plan), or routed into Rex via Zapier, an outbound webhook, or the REST API on Growth/Scale
| Data field | What Sift captures | Why it matters |
|---|---|---|
| chain_status | Chain-free / SSTC / under offer / renting | Fastest indicator of proceedability |
| mortgage_status | DIP in principle / AIP obtained / no mortgage needed | Separates browsers from buyers |
| buyer_type | Cash / mortgage-dependent / part-exchange | Sets vendor expectations upfront |
| gov_scheme | Help to Buy / Shared Ownership / First Homes / none | Scheme eligibility affects property match |
| budget_confirmed | Max budget (DIP-confirmed vs stated vs estimate) | Distinguishes real from aspirational budgets |
| timeline | Active / 1–3 months / 3–6 months / just looking | Right cadence for follow-up |
| lead_score | Hot / Warm / Cold (composite score) | Instant prioritisation for your team |
| transcript_url | Full conversation transcript | Context without having to call first |
Rex's AI Prospecting module finds and contacts potential vendors and buyers — it's an outbound tool. Sift is the inbound counterpart: it qualifies the leads that come to you. The two tools don't overlap; they stack.
If you're using Rex AI Prospecting and not qualifying inbound leads, you're generating interest at the top of the funnel while losing proceedable buyers at the bottom.

Sift has no native, built-in Rex CRM integration today. Qualified leads land in the Sift dashboard with full conversation transcript, GDPR consent record, lead score, and contact details — with CSV export on every plan. On Growth and Scale, leads can be routed into Rex via Zapier, an outbound webhook, or the REST API. A native Rex integration is on the roadmap.
Sift is a website chat widget that engages buyers the moment they arrive on your agency website — qualifying them through a structured conversation. Qualified leads land in the Sift dashboard with full transcript, GDPR consent, lead score, and contact details — with CSV export on every plan, and Zapier, an outbound webhook, or the REST API for routing into Rex on Growth/Scale. Rex handles the pipeline; Sift handles the pre-CRM qualification layer that Rex does not provide. A native Rex integration is on the roadmap.
Rex is a powerful CRM for managing your pipeline and client relationships. It does not include a website AI chat widget that qualifies buyers at the point of enquiry. Sift fills that gap: qualifying buyers on your website and surfacing clean, scored records in the Sift dashboard. Records can be exported via CSV, or routed into Rex via Zapier, an outbound webhook, or the REST API on Growth/Scale.
No. Sift operates as an independent website widget — it does not change your Rex configuration, workflows, or existing records. Most agencies are live in under 10 minutes: embed the widget and Sift starts qualifying immediately. Leads land in the Sift dashboard; CSV export is on every plan, with Zapier, an outbound webhook, or the REST API available on Growth and Scale for routing into Rex.
Sift is priced from £149/month (Starter) to £549/month (Scale), with all plans including the web chat widget, CSV export, and a 14-day free trial — no card required. Growth and Scale add Zapier, an outbound webhook, and REST API access for routing leads into Rex. Annual billing saves two months.
No Rex configuration needed. Embed the widget, and Sift handles the rest — leads land in your Sift dashboard, exportable via CSV, or routed into Rex via Zapier, an outbound webhook, or the REST API on Growth/Scale.
