Mod Ai hands your leads to a bot. Ace hands the AI to your agents.
Mod Ai is an autonomous AI concierge — it texts, calls, and emails your Follow Up Boss leads 24/7 with no agent reviewing any individual message before it goes out. Follow Up Ace is a self-serve AI layer inside Follow Up Boss where your agents approve every send. One of these approaches puts your brand, your compliance exposure, and your client relationships in a bot’s hands. The other doesn’t.
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 — no human reviews each message before it reaches your lead. Ace keeps a human on every send, with a code-enforced Fair Housing scan behind them.
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.

Lead scoring: a validated model vs. a conversation
“AI lead scoring” means very different things depending on what is behind it — and the difference matters, because that number decides which leads your team works first. It is worth knowing whether you are trusting a measurement or an opinion.
Ace’s scores come from a suite of calibrated machine-learning models — conversion, response, churn, and appointment-likelihood — trained on a behavioral data warehouse of real CRM outcomes, not a one-off language-model guess. They are validated on held-out data with published accuracy: several models score above 0.90 AUC, and the full methodology plus every model’s number (including the more conservative full-population model) is published in the Ace model evaluation report. They are calibrated — a 30 means roughly a 30% chance, not an arbitrary point on a 1–100 vanity scale — re-scored nightly and written into your Follow Up Boss custom fields, retrained weekly behind a promotion guard, and every prediction is logged and checked against what actually happened.
Mod Ai qualifies leads through conversation and can notify agents based on lead behavior (per its Follow Up Boss listing). That is useful — but it is a different thing. Its public materials do not publish a scoring model, held-out validation, or calibration. Conversational qualification tells you what a lead said in one exchange; a calibrated model tells you the probability a contact converts, so you can rank your entire database by it and trust the order.
Three questions to ask any “AI lead scoring” vendor
(1) Is it a validated model with published accuracy, or an undisclosed heuristic? (2) Is it calibrated — does a 70 actually mean about 70%? (3) Is every prediction checked against the real outcome? Ace publishes all three at /learn/model-evaluation. If a tool cannot answer these three, treat its “score” as an opinion, not a measurement.
The risk ledger of autonomous outreach
When an AI texts and calls your leads with no human reviewing each message, every one of those messages ships under your brand and your license. That is not a hypothetical — it is the operating model of every autonomous AI ISA, Mod Ai included. Before you turn one on, price in the ledger:
Compliance exposure, per message. The FCC ruled in February 2024 that AI-generated voices are “artificial” under the TCPA — meaning AI calls sit squarely inside consent rules, and TCPA statutory damages run $500–$1,500 per call or text. A bot that dials and texts at volume multiplies that arithmetic fast. Several states, including California, also require bots communicating to sell to disclose they are not human. Ask any autonomous-ISA vendor two questions: who verifies consent before the bot reaches out — and who indemnifies whom when a lead files? Read that clause before you sign.
Fair Housing, with nobody in the loop. Fair Housing liability attaches to what gets said to a lead — whether a human said it or an AI did. An autonomous bot that improvises conversations 24/7 is generating legal statements on your behalf around the clock, and no agent sees them before the lead does. One steering-adjacent sentence is all it takes.
Hallucination, at your client’s ear. Language models make things up. In a drafting tool, a made-up detail dies in review. In an autonomous bot, a fabricated price, a wrong school district, or an invented listing detail goes straight to a lead who believes they are texting a professional.
A deployment, not a product. Autonomous ISAs are configured to your team — scripts, calendars, escalation rules, voices — and changes go back through the vendor. That configuration is frozen the day setup ends, while the AI industry reinvents itself roughly quarterly. Ace is the opposite bet: a plug-and-play layer that ships improvements to every account automatically — nightly rescoring, weekly model retrains behind a promotion guard, new tools appearing without an upgrade project. When AI pivots, the layer pivots with it. A custom deployment waits for a rebuild.
And ask where your clients’ PII goes. When an AI service converses with your leads, their names, numbers, and conversations flow through AI models. As of our July 2026 review, the posted privacy policies at modai.org and modaiautomation.com say nothing about how that data is handled at the AI boundary — no tokenization, no redaction, no commitment not to train on it. Ace publishes its answer: emails and phone numbers are tokenized before any AI model sees them, and your data is never used to train models.
Five questions to ask Mod Ai — or any autonomous ISA — before you sign
(1) Who reviews each message before it reaches my lead? (2) Who carries the TCPA exposure — and what exactly does the indemnification clause say? (3) How does the bot disclose it is not human, in states that require it? (4) What compliance gate runs on each message before send — a policy, or code? (5) When the underlying AI models change, what happens to my configuration — and what does the change cost? Ace’s answers: your agent; there is no autonomous send to carry exposure for; not applicable — agents send as themselves; scan_message_for_compliance runs on every draft; and improvements ship to every account automatically.
When Mod Ai is the right choice
If you have weighed the risk ledger above and still want a hands-off bot contacting every lead — 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 defaults to agent-reviewed drafts — autonomous sending exists only in automations an admin explicitly enables, drafts-first and compliance-scanned. 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. Start at followupace.com/admin/signup.
How is Ace’s lead scoring different from Mod Ai’s?
Ace scores every contact with a suite of calibrated machine-learning models — conversion, response, churn, and appointment likelihood — trained on a behavioral data warehouse of real CRM outcomes. The models are validated on held-out data with published accuracy (several score above 0.90 AUC; see the model evaluation report), calibrated so the number maps to a real probability (a 30 means roughly a 30% chance), re-scored nightly and written into Follow Up Boss custom fields, and every prediction is checked against the actual outcome. Mod Ai qualifies leads through conversation and can notify agents based on behavior, but its public materials do not publish a scoring model, held-out validation, or calibration. Conversational qualification and a calibrated conversion-probability model are different tools — when comparing any AI CRM’s “lead scoring,” ask whether it is a validated, calibrated model or an undisclosed heuristic.
Is autonomous AI texting and calling legally risky?
It carries real, quantifiable exposure that any team should price in before signing with an autonomous AI ISA. The FCC ruled in February 2024 that AI-generated voices are “artificial” under the TCPA, so AI calls sit inside consent rules — and TCPA statutory damages run $500–$1,500 per call or text. Several states, including California, require bots communicating to sell to disclose they are not human. Fair Housing liability attaches to what gets said to a lead whether a human or an AI said it — and with an autonomous bot, no agent reviews any message before the lead sees it. Before signing with any autonomous ISA, ask: who reviews each message, who carries the TCPA exposure in the indemnification clause, how the bot discloses itself, and what compliance gate runs before send. Follow Up Ace avoids this category of risk entirely: agents approve every send, and a code-enforced Fair Housing scan runs on every draft.
