Best AI Transaction Coordinator (2026): 6 Options Compared

A deal rarely falls apart over the big stuff. It falls apart because a date got buried in an email. An AI transaction coordinator reads the contract, builds the timeline and chases everyone until the file closes.

The quick answer: Carly is the best AI transaction coordinator for agents and teams who want every file run on their own rules, from their own inbox. When a contract lands, it pulls every date onto your calendar, reminds the lender, title and the other agent from your address, and texts you before anything slips. For pay-per-file, ListedKit is the simplest option at $14.99 a transaction.

1. Carly

Carly runs the file the way your best coordinator would, every time. You write your checklist once in plain English, and it follows it on the first deal of the month and the fiftieth.

  • Contract to calendar. When a signed contract lands in your inbox, Carly pulls the inspection, appraisal, financing and closing dates onto your calendar and texts you before each one.

  • The chasing. Reminders to the lender, title and the other agent go out from your own address on your schedule, and stop when they reply.

  • Clients kept posted. An “under contract” checklist for every buyer, a weekly update for every seller and a review request at closing, each a free Zapier-style workflow.

  • Every document filed. Disclosures and addendums go to the right deal folder the moment they arrive.

  • Your phone covered. Carly answers when you’re in a showing, texts back every missed call and calls new leads within about a minute.

  • Your systems updated. Notes go to Follow Up Boss, dotloop or Carly’s built-in CRM, and Carly connects to thousands of apps.

  • Ask from ChatGPT or Claude. “What’s still open on the Maple Street file?” With the Carly connector, your AI chat can answer, and send the reminder too.

  • Best for: agents and teams who want one assistant on the deal, the leads and the inbox.

  • Pricing: Free Zapier-style workflows; AI agents from $35/month.

  • Setup: copy one prompt into ChatGPT or Claude, grab a number, and you’re live.

Carly business setup prompt

Paste this into ChatGPT or Claude. It sets up your deal checklist with you.

Help me connect Carly Teams so I can work with my organization's business texts, phone calls, voicemail and voice/text agents from this chat. I'll add it to you myself: tell me exactly what to click for the app you are, one step at a time, and wait for me to confirm before moving on. If a step doesn't match what I see, ask me what's on my screen. If you can do the setup yourself (Claude Code, Codex, Muse, Grok Bot), go ahead, and ask me for any key in your secure credential prompt, never in the chat. Don't tell me it's connected until list_phone_lines works, and if I have several teams, ask which to use. Before sending a text or making a call, confirm the team, recipient and message or task with me. The steps are below.

# Connect Carly Teams to an AI app

> Carly Teams works a team's business phone lines through the team's AI agents: business texts, phone calls, voicemail, the voice and text agents, and the team's CRM.

MCP server: https://carlyassistant.com/team/mcp (streamable HTTP, OAuth)

## Setup

Carly Teams isn't in any plugin or connector directory yet, so it's added as a custom connection by URL.

1. Add Carly Teams:
   - ChatGPT: open https://chatgpt.com/plugins, click Add, and choose Create MCP App (not Create plugin or Upload plugin archive). If Create MCP App isn't on the menu, turn on Developer mode first in Settings > Security and login. Name it "Carly Teams" with the description "Work with my team's business texts, calls, voicemail and voice/text agents," paste https://carlyassistant.com/team/mcp as the server URL, choose OAuth, create it, and sign in. Then in the message box open the + menu, choose Developer mode, and pick Carly Teams. No plugin needs to be built, packaged or uploaded.
   - Claude (claude.ai, Claude Desktop, or Cowork): Customize > Connectors > Add custom connector, name it Carly Teams, paste https://carlyassistant.com/team/mcp, and sign in.
   - Claude Code: `claude mcp add --transport http --scope user carly-teams https://carlyassistant.com/team/mcp`, then /mcp, pick carly-teams, and authenticate.
   - Codex: `codex mcp add carly-teams --url https://carlyassistant.com/team/mcp`, then `codex mcp login carly-teams`.
   - Cursor: add {"mcpServers": {"carly-teams": {"url": "https://carlyassistant.com/team/mcp"}}} to ~/.cursor/mcp.json, then sign in to carly-teams from Customize.
   - Muse: a custom connector to https://carlyassistant.com/team/mcp with a Carly API key as its bearer token. The key comes from carlyassistant.com/account (API key under Carly Teams) and goes in Muse's connector settings, not in a chat message.
   - Grok: grok.com/connectors > New Connector > Custom, paste https://carlyassistant.com/team/mcp, and sign in.
   - Grok Bot: a custom remote MCP server named carly-teams at https://carlyassistant.com/team/mcp. Approve it and sign in.
   - Perplexity: Plugins in the sidebar (or Customize > Connectors), then Add custom > Connector > Add MCP connector. Choose Remote, name it Carly Teams, paste https://carlyassistant.com/team/mcp, pick OAuth, check the box and click Add, then click the Carly Teams card to sign in.
   - Anything else: a remote MCP server (streamable HTTP) named carly-teams at https://carlyassistant.com/team/mcp. It signs in with OAuth.
   Sign in with the Carly account that belongs to the organization.

2. Once it's added, the Carly Teams tools show up in the chat, including list_phone_lines. If they don't, turn Carly Teams on for the chat or start a new chat.

3. To check it worked, call list_phone_lines: it returns the teams and phone lines the account can reach. A team with no phone line yet can get one with find_numbers (optionally by area code) and get_number, which may return a checkout link to finish.

4. Something to try first: "Review our missed calls and voicemail and help me reply to customers." Carly Teams also reads and answers business texts, has the team's agent make calls, and edits the voice and text agents. Texts and calls go out at once from the agent's number and can't be taken back. Team permissions apply.

## Email, calendars and workflows

Email, calendars, files, booking pages and workflows are the regular Carly connector, added separately. It's listed in ChatGPT's plugin directory (https://chatgpt.com/plugins/plugin_asdk_app_6a67a26316b88191860222f918d4ec54) and Claude's connector directory (https://claude.ai/directory/carly), and connects anywhere else at https://carlyassistant.com/mcp/. Its setup is https://carlyassistant.com/mcp.txt.

  • Pricing: $14.99 a transaction, down to $11 at volume, and your first is free. Credits never expire. Ava Sign is $29.99 a user a month.

  • Pricing: $39, $69, $99 or $199 a month, or $399 to $1,999 a year.

6. A human transaction coordinator

A good TC catches what software misses and is worth it on a messy deal.

  • Best for: complicated files and agents who want one person to call.
  • Pricing: about $300 to $500 a file by common industry estimates.
  • Limitations: the cost scales with every deal, and nobody works at 10pm on a Sunday.

What 10 closings a month costs

  • ListedKit: about $130, at its 10-credit rate.
  • Trackxi: $39 to $199, depending on plan.

How to pick

  • You want deals, leads and your inbox handled in one place: go with Carly.
  • You close a few deals a year and want to pay per file: ListedKit.
  • You’re a brokerage with compliance needs: ReBillion.
  • You’re an independent TC with several agents: Trackxi.
  • You have a messy deal: hire a person, and let Carly handle the reminders.

Whatever you pick, have a person or your broker sign off on compliance. This isn’t legal advice.

See what people say

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.

Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.

On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
