Hi, I saw the listing for the 2-bed in Brickell. Is it still available?

Hi! I'm Sara from Celebrity. Yes, it's available. Do you have time for a quick call tomorrow at 10am or do you prefer 2pm?

Multimodal

Reads audio, photos, and PDFs — like a human BDR

Leads send voice notes, listing screenshots, mortgage pre-approvals, sometimes a whole inspection report PDF. Sara parses all of it: Whisper transcribes audio, Vision reads images, PDF parser extracts text and tables. Everything is structured into lead signals automatically.

  • Whisper transcribes voice notes in any language
  • Vision reads listing screenshots and pre-approval letters
  • PDF parser handles inspection reports, market analyses
  • Every artifact becomes a structured lead_signal

Knowledge Base

Knows your market — without hallucinating

Generic AI guesses. Sara doesn’t. Each brokerage uploads its own Knowledge Base — listings, neighborhoods, school zones, closing process specifics. Sara retrieves from your base via hybrid search (vector + FTS + rerank) before answering. If the answer isn’t in the base, she says so and escalates.

  • Per-brokerage Knowledge Base (your data, isolated)
  • Crawl your own website or upload PDFs/markdown
  • Hybrid retrieval: vector + full-text + LLM rerank
  • "I don’t know" beats hallucinating — always

Smart handoff

Books showings, then escalates with a full briefing

When a lead is ready, Sara schedules a showing in your Google Calendar and pings your broker on WhatsApp + email. The handoff message includes lead profile, declared budget and timeline, top 3 objections detected, and recommended next move. Your broker walks in informed, not cold.

  • Books showings directly in Google Calendar
  • Handoff message: profile + BANT + objections + next move
  • Multi-channel: WhatsApp + email + in-app notification
  • Lead stays in Sara’s queue until human confirms takeover

Built for the way US brokerages actually work

Solo brokers, small teams, large brokerages — Sara adapts to your operation, not the other way around.

Solo broker, 100+ leads/month

You can’t reply to every Zillow lead within 5 minutes. Sara can. She filters out the noise and only pings you for the real ones.

Boutique team (5–15 agents)

No SDR budget but you’re losing leads to slow follow-up. Sara is your shared BDR — covers all inbound across the team’s shared number.

Brokerage 50+

You have SDRs but they go home at 6pm. Sara covers nights, weekends, holidays — and hands off in the morning with everything qualified.

Multi-language clientele

Buyer messages in Portuguese, Spanish, or English. Sara replies in their language, then briefs your broker in English (or any language you pick).

Past clients & referrals

Sara recognizes returning leads from your database, picks up the conversation where it left off, and routes to the broker who closed them.

New construction & off-market

Upload developer brochures and Sara learns the project — pricing, delivery, financing options. She pitches it the way you would.
