Mod AI Automation answers the phone. Ace makes your agents’ follow-up smarter.
Mod AI Automation is an AI voice-receptionist agency — its AI answers inbound calls and places outbound appointment-setting calls, priced around $199–$599/month.

Follow Up Ace is a self-serve AI layer inside Follow Up Boss: agents draft AI-assisted messages, scan them for Fair Housing compliance, and get calibrated lead scores in FUB — starting free. Mod AI Automation handles phone calls; Ace does not place AI calls — it makes your in-CRM follow-up smarter.
Two tools for two different jobs
The Mod AI Automation approach
Mod AI Automation is a voice-first AI agency. Per its own site (modaiautomation.com), it provides “AI voice technology, virtual receptionists, and AI-powered calling solutions across North America” — AI that answers inbound calls, places outbound appointment-setting calls with natural-sounding conversations, and can live-transfer to an agent. It references Follow Up Boss integration and lists pricing spanning roughly $199–$599/month across three tiers. The AI is on the phone; the agent takes the warm hand-off.
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 SMS and email, scanning every outbound message for Fair Housing compliance, getting Zillow cadence guidance, seeing calibrated lead scores written into FUB fields, and using FUB-aware agentic tools inside Claude.ai and ChatGPT. Ace does not answer your phone or place AI calls. It gives your agents AI in their hands, inside the CRM they already use, starting free.

When Mod AI Automation is the right choice
If you need an AI that actually answers your phone and books appointments by voice, Mod AI Automation is built for exactly that — and Ace is not.
Mod AI Automation’s specialty is voice. Its AI answers inbound calls so no lead hits voicemail, places outbound appointment-setting calls, and can live-transfer a warm caller to an available agent — a genuine virtual-receptionist capability that Follow Up Ace does not offer. For a team drowning in inbound phone volume, or one that wants outbound calls dialed and conversed automatically, that voice-first model is valuable.
Ace is not a phone system. Ace gives your agents AI assistance inside Follow Up Boss — drafting text and email, scanning compliance, scoring leads, and surfacing what to do next — while keeping a human on every message. The two are not mutually exclusive: plenty of teams run an AI voice tool for the phone and Ace for in-CRM intelligence. Choose Mod AI Automation when the job is phone calls; choose Ace when the job is smarter, agent-controlled follow-up inside the CRM you already run.

Mod AI Automation vs Ace — frequently asked
What is Mod AI Automation?
Mod AI Automation (modaiautomation.com) is, in its own words, a “leading AI automation agency specializing in AI voice technology, virtual receptionists, and AI-powered calling solutions across North America.” Its AI answers inbound calls and places outbound appointment-setting calls, and it integrates with Follow Up Boss. It is a voice-first product. Follow Up Ace is different — a self-serve AI layer inside Follow Up Boss where agents draft and approve the messages themselves; it does not place AI phone calls to your leads.
How much does Mod AI Automation cost?
Mod AI Automation’s own website lists AI voice technology pricing spanning roughly $199 to $599 per month across three tiers (per its published product data). AI voice-agent services also commonly carry per-minute or setup costs depending on call volume — check modaiautomation.com/pricing for current rates, which may have changed since this page was last updated. Follow Up Ace offers a free plan, plus paid seats (see followupace.com/#pricing).
Does Mod AI Automation work with Follow Up Boss?
Yes — Mod AI Automation references Follow Up Boss integration on its site, and the related Mod Ai listing on the Follow Up Boss Marketplace connects via secure API to sync leads and trigger follow-ups. It is a third-party AI voice service that connects to FUB. Follow Up Ace is a FUB Marketplace-certified native embed that runs inside the Follow Up Boss interface — and it never contacts your leads unless your agent drafts and sends the message.
What is the difference between Mod AI Automation and Follow Up Ace?
Mod AI Automation is an AI voice receptionist and caller: it answers inbound phone calls and makes outbound appointment-setting calls with an AI voice, priced around $199–$599/month. Follow Up Ace is an agent-controlled AI layer inside Follow Up Boss: it drafts SMS and email for the agent to review and send (with a Fair Housing scan on every message), writes calibrated lead scores into FUB fields, and connects FUB to Claude and ChatGPT via MCP. Mod AI Automation handles phone conversations for you; Ace makes your agents and your CRM smarter while keeping a human on every outbound message. They solve different problems and are often complementary.
Does Follow Up Ace make AI phone calls to leads?
No. Follow Up Ace does not place autonomous AI phone calls to your leads. Its voice feature is an agent-facing assistant — it answers questions, summarizes, and prepares drafts for the agent — not an outbound calling bot or a receptionist that answers your phone. If you specifically want an AI that handles phone calls, that is what Mod AI Automation does; Ace focuses on agent-controlled text/email drafting, lead scoring, and CRM intelligence inside Follow Up Boss.
Is there an alternative to Mod AI Automation for Follow Up Boss?
It depends what you need. If you want AI phone calling specifically, Mod AI Automation is a voice-first specialist. If you want AI leverage inside Follow Up Boss without an autonomous calling service — agent-drafted messages, Fair Housing compliance scanning, calibrated lead scores in FUB fields, and a Claude/ChatGPT connector — Follow Up Ace is a free-to-start alternative that keeps your agents in control of every message. Many teams use a voice tool for the phone and Ace for in-CRM AI. Start at followupace.com/admin/signup.
