Brokki is the toolkit for Dubai real estate brokers. We work the floor too, so we build exactly what an agent actually needs. What brokki does: • Instant property valuations — sale price, rental yield and a confidence range in seconds, built on 1.5M+ real DLD transactions. • Client-ready PDF reports in one tap. • Your whole stock in your pocket, with an auto market estimate on each. • A client list that sorts buyers by who's actually warm. • Private collections — a few hand-picked properties, one link, no login. • Client interest — see what your client opened and liked, so your next call lands right. • Market Pulse — the Dubai market at a glance, live from DLD & RERA. And this is just the start — brokki is growing into a full daily toolkit for brokers.
