7 Best AI Automation Tools for ADP in 2026
ADP’s AI is called ADP Assist, and on RUN it comes with every package. It answers your payroll and HR questions, and its payroll inspector flags common mistakes before you submit. It also imports hours from the timesheet file you already use. On Workforce Now, ADP Assist surfaces payroll anomalies and explains what changed. ADP Assist Agents are rolling out to catch pay variances and answer policy questions, and employees can reach ADP Assist in Microsoft Teams and Microsoft 365 Copilot.
That covers what happens inside ADP. The rest still lands on you. Josh emails asking where his W-2 is. Three managers still haven’t approved timecards and payroll closes tomorrow at noon. A new hire needs her paperwork list and a first-day schedule. Half the team hasn’t elected benefits, and your accountant wants last quarter’s payroll register by Friday.
Below are seven tools, ranked by how much of that work they take off your plate.
TL;DR: Use ADP Assist for questions and error checks inside ADP. Add Carly for the email, calendar, and follow-up around payroll. It reads the request, does the work, and connects to thousands of apps, including Gmail, Outlook, Slack, Microsoft Teams, and Google Calendar.

1. Carly
Carly is an AI agent with its own email address, connected to your inbox, your calendars, and Slack. You email it, text it, CC it on a thread, or message it in Slack, and it does the work:
- Pay stub and W-2 questions. Josh emails asking where his W-2 is. Carly replies with the MyADP steps you gave it once. If he writes back that his address is wrong, it flags the email to you.
- Timecard approvals before the cutoff. The day before payroll closes, Carly emails every manager who approves time. It follows up at 10am, then texts you a list of anyone who still hasn’t replied.
- Onboarding. Claire accepts the offer. Carly sends her welcome email with her start date and what to bring for the I-9. It books orientation and her first-week 1:1s on her manager’s calendar, then reminds you to add her in ADP before the next payroll.
- Time off by email. Emily asks for the 14th through the 18th. Carly checks the team calendar for overlap, blocks the week, replies to Emily, and reminds her manager to approve it in ADP.
- Open enrollment. Forward the list of who hasn’t elected benefits. Carly sends each person a personal reminder with the deadline, follows up three days out, and flags the replies with questions.
- The accountant. Your CPA asks for the Q3 payroll register. Carly finds the export in your inbox or Drive, attaches it, and replies.
What makes it different: ADP Assist works inside ADP. Carly starts from the message. It reads all of your Gmail and Outlook mailboxes and your Google Calendar together, so an email like “can I take Friday off?” ends with the time blocked and a reply sent.
It runs on event triggers and fires when a new email, form, or calendar event arrives. Your morning inbox is handled before you open it. Predictable steps, like posting every new hire’s start date to a Slack channel, run as free Zapier-style workflows. The judgment calls, like answering a pay question from an upset employee, run on AI agents.
Connect ADP: ADP doesn’t issue simple API keys. On Workforce Now, the path is ADP’s paid API Central add-on. On RUN, ask ADP for API or MCP access. Carly connects as soon as ADP provides it, and the Carly team will do the setup with you on a call. Everything above works from day one, before ADP is connected at all.
Best for: Owners, office managers, and payroll admins on RUN or Workforce Now who get the people requests in their inbox.
Pricing: Free Zapier-style workflows; AI agents from $35/month
2. ADP Assist
ADP’s built-in AI. On RUN, every package includes the ADP Assist virtual assistant, the payroll inspector that flags errors before they hit a pay run, and smart timesheet import. On Workforce Now, it detects payroll anomalies, explains what changed, and answers questions in plain language. ADP Assist Agents, built on Amazon Bedrock, handle variance resolution and policy answers grounded in your own handbook. Employees can use it in Microsoft Teams and Microsoft 365 Copilot to check PTO and ask pay questions.
What makes it different from Carly: it knows your payroll data better than anything else here, and it’s native. It can’t read your inbox, though. Josh’s W-2 email and the manager who owes timecards stay outside it.
Best for: Catching payroll errors and answering “how do I do this in ADP.”
Pricing: Included in every RUN package; Workforce Now pricing through ADP
3. Claude or ChatGPT
Great analysts for an ADP export. Download a payroll register or PTO report, upload the CSV, and ask what drove overtime this month or which departments ran over budget. They also draft payroll-change announcements and open enrollment emails well.
What makes it different from Carly: ADP has no connector in Claude’s directory and hasn’t announced one for ChatGPT, so you export, upload, and prompt every time. Nothing runs between chats. More in Claude + ADP.
Best for: One-off analysis of a report you already downloaded.
Pricing: Paid plans from ~$20/month
4. Zapier
Trigger-action automation across thousands of apps, with AI steps for drafting and parsing.
What makes it different from Carly: Zapier’s directory lists ADP only as an upcoming app, with no live triggers or actions. A Zap can react to the offer email or a form submission, but it can’t read ADP. Every Zap is plumbing you build and maintain. See Zapier alternatives.
Best for: Simple form-to-spreadsheet or email-to-Slack steps around your HR process.
Pricing: Free plan; paid from ~$19.99/month
5. Make
A visual canvas with branching, loops, and data transforms.
What makes it different from Carly: Make has no ADP app. Reaching ADP means HTTP modules loaded with API Central credentials and security certificates, which only Workforce Now and larger ADP platforms can buy. You get more control and more canvas to debug. See Make alternatives.
Best for: Technical operators on Workforce Now who already bought API Central.
Pricing: Free plan; paid from ~$12/month
6. n8n
Open-source and self-hostable, with AI agent nodes.
What makes it different from Carly: there’s no ADP node, so you call ADP’s APIs through the HTTP Request node with API Central credentials. It’s the most private option for payroll data, but you host, build, and maintain all of it yourself. See n8n alternatives.
Best for: Companies with an engineer who wants employee data on their own servers.
Pricing: Free self-hosted; cloud from ~$20/month
7. Gusto or Rippling (if you’re switching)
Some people searching “ADP AI” are really asking whether another payroll system does it better. Gusto includes Gus and has Gusto Cofounder in early access. Rippling AI answers questions from your live Rippling data and builds workflows in Workflow Studio. Both run official MCP servers. See AI tools for Gusto, AI tools for Rippling, and AI tools for BambooHR.
What makes it different from Carly: switching is a migration, and their assistants still work on their own data, not your inbox. Carly works with the ADP you already run.
Best for: Small businesses already planning to leave ADP.
Pricing: Varies by platform and plan
Which ADP AI Tool to Use
- You want payroll errors caught before you submit: ADP Assist, already included on RUN.
- You want to analyze a report once: Claude or ChatGPT with an export.
- You have a developer and Workforce Now: API Central plus n8n or Make.
- You’re leaving ADP anyway: look at Gusto or Rippling.
If the payroll work reaches you by email, Slack, and calendar, go with Carly. It reads the request, decides what it needs, and acts as soon as it arrives.

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."
