Mod Ai runs the conversation for you. Ace puts the AI in your agents’ hands.
Mod Ai is an autonomous AI concierge — it texts, calls, and emails your Follow Up Boss leads 24/7 and books appointments on its own. Follow Up Ace is a self-serve AI layer inside Follow Up Boss where your agents draft and approve every message. Both work leads. They take opposite approaches to who is in control.
Mod Ai vs Follow Up Ace: Mod Ai is an autonomous AI inside sales assistant — per its Follow Up Boss Marketplace listing it engages, qualifies, and books leads with AI follow-ups “via texting, voice, and email,” 24/7. Follow Up Ace is a self-serve AI layer inside Follow Up Boss: your agents draft AI-assisted messages, scan them for Fair Housing compliance, and get calibrated lead scores in FUB — starting free. Mod Ai runs the conversation for you; Ace keeps a human on every send.
Two different bets on the same job
The Mod Ai approach
Mod Ai is an autonomous AI concierge. When a lead comes in, Mod Ai’s AI reaches out on its own — texting, calling, and emailing to engage and qualify, then booking appointments directly into the calendar, 24/7. Per its Follow Up Boss listing, it “plugs directly into Follow Up Boss using secure API connections,” syncs lead data in real time, and can trigger action plans, assign tasks, and notify agents. Its own site (modai.org) frames it as a “luxury AI concierge for top-producing real estate teams.” The AI runs the conversation; you focus on closing.
The Ace approach
Ace is a self-serve AI layer that runs inside Follow Up Boss — FUB Marketplace certified, no second login. Your agents use Ace directly: drafting AI-assisted messages, scanning every outbound message for Fair Housing compliance, getting Zillow cadence guidance on Zillow contacts, seeing calibrated lead scores written into FUB fields, and using FUB-aware agentic tools inside Claude.ai and ChatGPT. Ace does not message your leads on its own. It gives your agents AI in their hands, inside the CRM they already use, starting with a free plan.

When Mod Ai is the right choice
If you want a hands-off bot that contacts every lead the instant it lands — including AI voice calls — Mod Ai is built for exactly that.
Mod Ai’s strength is autonomous, round-the-clock outreach. It engages, qualifies, and books leads on its own across text, voice, and email, so a lead that comes in at 11pm gets an immediate AI response without an agent lifting a finger. For high-volume teams that value speed-to-lead at all hours over reviewing each message — and especially teams that want AI voice conversations with leads, which Ace does not offer — that autonomous model is genuinely valuable.
Ace is not an autonomous ISA. Ace gives your agents direct control over AI assistance inside FUB — they draft messages, the AI assists, compliance is scanned, Zillow context is injected, and lead scores are written back into FUB. If you want the AI to run conversations without your agents drafting them, Ace’s model is different by design. Mod Ai is the right call for teams that want to outsource first-touch outreach to a bot; Ace is the right call for teams that want to stay in the loop on every message and make the whole CRM smarter.

Mod Ai vs Ace — frequently asked
What is Mod Ai?
Mod Ai is an autonomous AI inside sales assistant for real estate teams. Per its Follow Up Boss Marketplace listing, it is an “intelligent inside sales assistant for 24/7 lead conversion” that engages and qualifies leads and books appointments, with AI follow-ups via texting, voice, and email that sync back to Follow Up Boss. Its own site (modai.org) positions it as a “luxury AI concierge for top-producing real estate teams.” In short: Mod Ai contacts your leads for you, automatically.
How much does Mod Ai cost?
Mod Ai is listed as “Free” to install on the Follow Up Boss Marketplace, though autonomous AI calling and messaging services in real estate are typically priced by usage or plan — check modai.org for current pricing, which may have changed since this page was last updated. Follow Up Ace also offers a free plan, plus paid seats (see followupace.com/#pricing).
Does Mod Ai work with Follow Up Boss?
Yes. Per its Follow Up Boss Marketplace listing, Mod Ai “plugs directly into Follow Up Boss using secure API connections,” syncs lead data in real time, automates follow-ups via AI texting, voice, and email, and can trigger action plans, assign tasks, and notify agents. It is a third-party API integration. Follow Up Ace also works with Follow Up Boss, but as a FUB Marketplace-certified native embed that runs inside the FUB interface — and it never messages your leads unless your agent drafts and sends it.
What is the difference between Mod Ai and Follow Up Ace?
Mod Ai is an autonomous AI concierge/ISA: it contacts your leads directly via AI text, voice, and email, qualifies them, and books appointments 24/7 — the AI runs the conversation. Follow Up Ace is an agent-controlled AI layer inside Follow Up Boss: it drafts messages your agent reviews and sends (with a Fair Housing compliance scan on every outbound message), scores leads with calibrated models written into FUB fields, and connects Follow Up Boss to Claude and ChatGPT via MCP. Mod Ai automates the outreach; Ace makes your agents and your CRM smarter while keeping a human on every send.
Does Mod Ai call and text leads automatically?
Yes — that is the core of what Mod Ai does. Its Follow Up Boss listing describes 24/7 AI follow-ups “via texting, voice, and email” and “inbound call handling,” meaning the AI reaches out to and converses with leads on its own. Follow Up Ace works differently: it never sends messages to your leads on its own. Ace drafts SMS and email for your agent to review and send, and its voice feature is an agent-facing assistant, not an autonomous bot that calls your leads. If you specifically want hands-off AI voice calls to leads, that is a Mod Ai capability, not an Ace one.
Is there an alternative to Mod Ai for Follow Up Boss?
Follow Up Ace is an alternative for FUB teams that want AI leverage without handing lead conversations to an autonomous bot. It offers a free plan — no credit card, no demo, no setup fee — with an FUB-embedded AI chat, a Fair Housing compliance scanner, and a Zillow speed-to-lead advisor. It is not a like-for-like replacement for Mod Ai’s autonomous outreach (Ace is agent-controlled, not a hands-off ISA), but for agents who want to stay in the loop on every message, it is a practical starting point.
