Summarize content with:

HouseWhisper has quickly become the AI assistant that top real estate agents are “obsessed with,” and for good reason. By acting as a personal assistant that agents can text or call to update their CRM, manage tasks, and set reminders, it solves one of the biggest pain points in the industry: getting agents to actually use their software. It’s a brilliant “plug & play” solution for offloading busywork so agents can focus on closing deals. Launched by ex-Execs from a big name like Zillow, HouseWhisper has just raised $6.7 Million USD at the start of 2025. 

But what if your needs go beyond a personal assistant? What if you want an AI that can also handle outbound prospecting, qualify new inbound leads 24/7, or is already built into the CRM you use every day?

The AI assistant market is booming, and several strong HouseWhisper alternatives offer different strengths. This guide breaks down the top five contenders to help you choose the right one for your business.

What Makes A Good Housewhisper Alternative?

HouseWhisper sets a high bar with its simplicity and agent-first design. To be a worthy alternative, a platform should be evaluated on:

  • Primary Function: Is it a personal assistant for the agent, or an outbound agent that engages leads directly?
  • Interface: How do you interact with it? Via text/call (like HouseWhisper), a dashboard, or within your CRM?
  • CRM Integration: How deeply and seamlessly does it sync notes, lead stages, and tasks?
  • Proactivity vs. Reactivity: Does it just take your commands, or can it proactively manage workflows, remind you of tasks, and engage leads on its own?
  • Real Estate Focus: Is it built from the ground up for agents, or is it a general-purpose tool adapted for real estate?

1. Contactswing: Best For Proactive, Omnichannel Lead Engagement

While HouseWhisper acts as your personal assistant, ContactSwing provides you with an AI agent that can proactively handle communication across your entire funnel. It’s less about reminding you to make a call and more about making the call for you.

Key Features

  • 24/7 AI Voice Agents: Deploys human-like AI to make and receive calls for lead qualification, appointment booking, and follow-up.
  • Omnichannel Workflow: Manages interactions across voice, SMS, and email from a single platform, ensuring a consistent experience.
  • No-Code Builder: Allows you to design and launch sophisticated call campaigns and workflows in minutes without needing developers.
  • Real-Time CRM Sync: Deeply integrates with HubSpot and other CRMs to log every call, update lead statuses, and trigger workflows automatically.
  • Advanced Sentiment Analysis: The AI understands the caller’s tone and intent, adapting its approach and escalating to a human agent when needed.

Why Choose Contactswing Over Housewhisper?

HouseWhisper excels at helping you manage your existing pipeline and tasks. ContactSwing excels at filling that pipeline and handling the first touchpoints for you.

  • Outbound Calling: ContactSwing’s AI can cold call lead lists, follow up on old portal inquiries, and re-engage past clients automatically, a function HouseWhisper doesn’t focus on.
  • Top-of-Funnel Qualification: It can act as your first line of defense, qualifying new website or ad leads instantly before they even hit your CRM, ensuring 100% speed-to-lead.
  • Greater Autonomy: You can build entire workflows that run without your direct input, whereas HouseWhisper is primarily designed to respond to and assist you, the agent.

You can also try ContactSwing’s AI agents through their free trial.

Best For

Agents and teams who want to automate not just their own admin work, but also their lead qualification and outbound prospecting efforts. Outbound calling, SMS, WhatsApp, and email base ai automation serve as important tools for a real estate agent in order to expand their reach and availability. Using property-based triggers, ContactSwing can set up meetings for you automatically by walking users through a first discovery call on its own. 

2. Follow Up Boss AI

For the thousands of agents and teams who live inside Follow Up Boss, the native AI features are a compelling alternative. It’s less of a separate “assistant” and more of an integrated intelligence layer within the platform you already use.

FAQs

Q1. Is HouseWhisper’s conversational AI unique?
No. While its focus on being a personal assistant is unique, other platforms like ContactSwing also offer highly advanced conversational AI that can handle both inbound and outbound calls with a human-like feel.

Q2. Do I need to switch my CRM to use these alternatives?
No. Tools like ContactSwing are designed to integrate with your existing CRM, including platforms like HubSpot, so you don’t lose your data. Native solutions like Follow Up Boss AI and Sierra Interactive AI are features of a CRM.

Q3. How is an AI assistant different from a human virtual assistant (VA)?
An AI assistant is available 24/7, can handle thousands of tasks or calls simultaneously without getting tired, and often costs less at scale. A human VA provides deeper strategic thinking and can handle tasks that require more nuanced judgment. Many teams use both.

Q4. Can I use more than one of these tools?
Yes, but be careful. For example, you could use Ylopo to generate leads and HouseWhisper to help you manage them, but you risk creating a complex and expensive tech stack. It’s often better to choose one platform that solves your primary bottleneck.
