Ace AI vs. ChatGPT: Follow Up Boss Integration

By the Follow Up Ace team· Last updated
Quick answer

Ace is a purpose-built intelligence layer that lives inside Follow Up Boss — scoring every lead, running voice commands, and writing AI-scored fields directly back to your CRM. ChatGPT can connect to Follow Up Boss via the Ace MCP connector (SSE URL: https://followupace.com/api/mcp/sse/), giving it live read/write access to your FUB data. Both paths are available on the Ace Pro plan.

What is the difference between Ace AI and ChatGPT for Follow Up Boss?

Ace and ChatGPT are complementary, not competing. Ace is an embedded CRM intelligence layer that scores contacts, writes custom fields, and surfaces prioritized call queues without agents leaving Follow Up Boss. ChatGPT is a general-purpose AI model that can query and update FUB data conversationally once an MCP connector is in place. The right question is not which one to use — it is which job each does best.

Capability Ace (native) ChatGPT via MCP
Embedded in FUB sidebar Yes — no tab switching No — separate browser window
AI lead scoring (Ace Score 0–100) Yes — auto-writes FUB custom fields Can read scores via MCP; cannot originate them

Fair Housing compliance scan Yes — built-in Via MCP tool (same engine)
Free-form natural language queries Yes — chat interface Yes — full GPT reasoning
Live FUB read + write access Yes Yes — 200+ MCP tools
Setup complexity Zero — auto-connects on signup Paste one SSE URL into ChatGPT settings

How does Ace AI integrate with Follow Up Boss natively?

Ace embeds directly into the Follow Up Boss interface as an intelligent sidebar. Once a user connects their FUB account, Ace reads contact activity, calculates a multi-dimensional lead score, and writes the results back as FUB custom fields — no export, no copy-paste, no separate dashboard required.

The Ace Trove populates these verified custom fields for every contact:

Because these fields live natively in FUB, agents can build Smart Lists and filters on them — for example, a "Hot Leads Call Queue" that surfaces every contact with Ace Score ≥ 80 and Ace Tier = Hot, sorted by score descending. The list updates itself as Ace re-scores contacts.

What plan do you need for Ace AI in Follow Up Boss?

Ace offers three user-level plan tiers (verified in chat-app/routes/embed.js):

Voice and MCP connector access are gated at the Pro plan level (voiceChatEnabled: toPlan === 'pro', embed.js:2647; proRequired: planType !== 'pro', embed.js:4311). Admins can purchase seats on behalf of agents (team-pay) or agents can self-pay — both modes are supported.

For account-wide Ace Trove features (pipeline health checks, nightly batch scoring of the full contact database, and the lead-nurture optimizer), teams use the Ace Trove flat-rate subscription, which starts at $49/mo for up to 5,000 contacts and scales to $899/mo for up to 500,000 contacts.

How do you connect ChatGPT to Follow Up Boss?

The Ace MCP connector gives ChatGPT (and Claude) direct read/write access to your FUB account through 200+ pre-built tools. You do not need to write any code. The connector works on the Pro plan and requires pasting a single URL into your AI client's settings.

Step-by-step: connecting ChatGPT to Follow Up Boss via MCP

  1. Upgrade to the Ace Pro plan at followupace.com/#pricing.
  2. In your Ace dashboard, navigate to the MCP Integrations panel. Your personal SSE connector URL will be shown there.
  3. In ChatGPT, go to Settings → Connectors and add a new connector.
  4. Paste the SSE URL: https://followupace.com/api/mcp/sse/
  5. Authorize the connection. ChatGPT can now query contacts, log notes, update stages, check pipeline health, and run compliance scans — all within FUB — using plain English.

For Claude (Anthropic), use the Streamable HTTP URL instead: https://followupace.com/mcp. Both endpoints are verified in chat-app/routes/embed.js:4307–4309.

What can ChatGPT actually do inside Follow Up Boss via MCP?

Once connected, ChatGPT has access to 200+ tools covering the full breadth of your FUB account. Practical examples:

The MCP path lets you use ChatGPT's general reasoning on top of your real CRM data — writing outreach drafts grounded in a lead's actual activity history, or combining multiple FUB queries into a single coherent answer that no built-in FUB filter could produce alone.

Does Ace AI score leads automatically, or do I have to trigger it?

Both modes run in parallel. The Ace Trove scores contacts as new activity arrives and runs a nightly account-wide batch analysis so every contact in your database is re-evaluated on a regular cadence — not just contacts who had activity that day. You do not need to trigger anything manually. The Ace Score, Ace Tier, and related fields in FUB are kept current without agent involvement.

Scoring uses a multi-dimensional model (verified in aceIntelligenceConfig.js) that weights:

The practical result: your FUB Smart Lists built on Ace Score stay accurate without manual curation. A contact who searches for properties three days in a row moves up the call queue automatically; a contact who goes silent for a month drifts down.

How does Ace handle Fair Housing compliance in Follow Up Boss messages?

Every AI-drafted message in Ace passes through a built-in compliance scanner before it reaches the agent. The scanForComplianceViolations() function (verified in chat-app/utils/complianceGuard.js:293) checks text against prohibited Fair Housing terms and patterns, flags any violation at severity level high, and surfaces an inline warning rather than silently sending the message.

The same scan is available through the MCP connector, so ChatGPT users can call it on any draft before sending. This is not a workaround — it is the same code path used by the Ace native interface. Learn more about the compliance scanner and what it checks.

What are Ace Trove Recipes, and why do they matter for Follow Up Boss power users?

Ace Trove Recipes are pre-configured Smart List blueprints that turn Ace's custom fields into actionable FUB workflows with a few guided steps. Because FUB does not allow external tools to create Smart Lists via its API, Ace provides the exact filter configuration so the admin can paste it in and save the list in seconds.

Current verified recipes (from chat-app/utils/aiEngineRecipes.js):

These recipes turn raw AI scores into FUB-native list management that agents recognize and trust, without requiring agents to understand how the scoring model works.

When should you use Ace AI, and when should you use ChatGPT with MCP?

The two approaches address different needs. Use this as a rough guide:

Use case Best tool
Daily lead prioritization inside FUB Ace — always-on, zero friction
Voice commands while driving or on the go Ace Pro — built-in voice support
Writing personalized outreach from contact history Either — Ace chat or ChatGPT with MCP context
Complex multi-step analysis across many contacts ChatGPT via MCP — deeper reasoning on CRM data
Account-wide pipeline health monitoring Ace Trove (pipeline-health-check tool)
Drafting and screening messages for Fair Housing compliance Ace compliance scan — same engine via both interfaces

Most Pro users end up using both: Ace for the always-on scoring, call queue, and voice commands while working inside FUB, and ChatGPT (or Claude) via MCP for deep research sessions or bulk operations that benefit from more elaborate prompting.

How does Ace AI compare to ChatGPT for Zillow and inbound speed-to-lead?

Inbound speed is one of the clearest wins for a purpose-built CRM layer over a general-purpose AI. Ace includes a dedicated lead_speed_to_lead_check tool (verified in mcp-server/src/http-server.ts:508) that evaluates response time to portal leads — including Zillow Premier Agent — and flags contacts where speed-to-lead has slipped. ChatGPT with MCP can invoke the same tool, but the check only works because Ace has already built the portal-lead logic into the connector.

For teams relying heavily on Zillow lead flow, the Zillow Playbook documents how Ace surfaces and scores these leads inside FUB.

Frequently asked questions

Does using ChatGPT with MCP require a separate ChatGPT subscription?

The MCP connector itself is included with Ace Pro. You still need a ChatGPT account that supports custom connectors (currently ChatGPT Teams or higher). The Ace MCP subscription and the ChatGPT subscription are billed separately.

Can I use the Ace MCP connector with Claude (Anthropic) instead of ChatGPT?

Yes. Use the Streamable HTTP endpoint https://followupace.com/mcp in Claude's MCP settings. Both endpoints are on the same backend and expose the same 200+ tools.

Is my Follow Up Boss data sent to OpenAI when I use ChatGPT with MCP?

When ChatGPT calls an MCP tool, the tool arguments and responses are processed by OpenAI's infrastructure. Review OpenAI's data usage policies and your ChatGPT enterprise data controls before connecting sensitive CRM data. Ace does not store what ChatGPT sends through the connector beyond standard server logs.

Does Ace AI work for solo agents or only for teams?

Ace works for solo agents and teams equally. Solo agents self-pay on the Regular or Pro plan. Teams can use admin-purchased seats (team-pay) where the brokerage covers the subscription. Both billing paths are fully supported. See the feature comparison for details on how Ace fits different team sizes.

What is the difference between the Ace Trove and a per-seat Ace Pro plan?

Per-seat plans (Regular $25, Pro $55) are purchased per individual agent and cover that agent's chat, voice, and MCP access. The Ace Trove is a flat-rate account-wide subscription ($49–$899/mo depending on contact count) that enables nightly batch scoring of the entire FUB contact database, the pipeline health check, the lead nurture optimizer, and the Ace Trove Recipes. They can be purchased independently or together.
