7 Best AI Automation Tools for Gusto in 2026
Gusto is the rare payroll app where the AI is genuinely useful. Gus answers payroll, benefits, and compliance questions inside Gusto and runs reports on your own data. Gusto Cofounder, in early access since June, goes further: it runs payroll on a schedule, chases missing timesheets, and texts you when a run looks off. And Gusto now plugs straight into ChatGPT, Claude, and Slack.
So payroll is covered. What still lands on you is everything around it: the offer letter that has to go out today, the new hire who still has not finished onboarding, the PTO request that arrives as an email or a Slack DM instead of in Gusto, the calendar that needs blocking for Emily’s week off, and the first-week meetings someone has to book.
Below are seven tools, ranked by how much of that work they take off your plate.
TL;DR: Keep Gus on for Gusto questions, and join the Cofounder waitlist if you want payroll on autopilot. Add Carly for the people work that arrives by email, Slack, and calendar. It reads the request, checks Gusto, does the follow-up, and connects to thousands of apps, including Gusto, Gmail, Outlook, Slack, and Google Calendar.

1. Carly
Carly is an AI agent with its own email address, connected to your inbox, your calendar, Slack, and Gusto. You text it, email it, CC it on a thread, or message it in Slack.
Gus and Cofounder start from Gusto. Carly starts from the message:
- Offer accepted. Michael replies “I’m in, see you on the 6th.” Carly sends the welcome email with the start date, books his first-week check-ins, and a week later checks his onboarding status in Gusto and nudges him if a step is still open.
- Time off by email. Josh asks for the 14th through the 18th. Carly checks the team calendar for overlap, blocks the week, replies to Josh, and reminds you to approve it in Gusto.
- Payroll prep. Every Tuesday before a Thursday run, Carly checks Gusto for anything blocking payroll and emails you the list while there is still time to fix it.
- Quick lookups. A manager asks in Slack for Claire’s start date and title. Carly pulls it from Gusto and answers in the thread.
What makes it different: it runs on events, not prompts. When the email lands, Carly acts, unattended, so the morning inbox is already handled. Predictable steps, like posting every new hire to a Slack channel, run as Zapier-style workflows, which are free. The judgment calls, like replying to a PTO request that clashes with a busy week, run on AI agents.
Connect Gusto: in Carly, go to Integrations → MCP servers and add Gusto’s server, https://mcp.api.gusto.com. A Gusto admin signs in once to approve access. Want a hand setting up the Gusto side? Book a call with the Carly team.
Best for: Owners and office managers who run payroll in Gusto but field the people requests in their inbox.
Pricing: Free Zapier-style workflows; AI agents from $35/month
2. Gusto Cofounder
Gusto’s AI teammate, launched June 2, 2026. It starts with context on your team, pay schedule, benefits, and compliance calendar, ships with more than 20 pre-built automations across onboarding, payroll, expense approvals, and compliance, and you reach it by text, Slack, or the web. “Run payroll every Friday and text me if anything is more than 10% off last week” is a real instruction.
What makes it different from Carly: it is the deepest payroll agent here, and it is still in early access for a select group of customers. Its center of gravity is Gusto. Carly’s is your inbox and calendar, across every tool the business runs, and it is live today.
Best for: Gusto customers who want payroll itself to run without them.
Pricing: Early access waitlist; no published price
3. Gus
Gusto’s built-in AI assistant, available to employers and employees on the web and in the mobile app. It answers payroll, benefits, time tracking, and compliance questions from Gusto’s own knowledge, runs reports on your company’s data, and can take actions like approving a PTO request or changing someone’s manager after you confirm.
What makes it different from Carly: it is the best answer to “how do I do this in Gusto,” and it is native. It works on what is already in Gusto. The PTO request sitting in your inbox still has to get there.
Best for: Fast answers about payroll rules and your own Gusto data.
Pricing: Included with Gusto
4. Claude or ChatGPT with the Gusto connector
Gusto launched an official app in ChatGPT in January 2026 and in Claude and Slack in April. Ask what drove last period’s payroll increase or how much overtime cost this quarter, and get a report or a chart back. Eligible customers can run payroll in the chat during early access.
What makes it different from Carly: excellent for analysis, and it acts only when you open the chat and ask. Nothing happens when the new hire’s email arrives at 7am. More in ChatGPT + Gusto.
Best for: Owners who want to interrogate payroll data in plain English.
Pricing: Paid plans from ~$20/month
5. Rippling AI
If the real question is whether to leave Gusto, Rippling is the platform people weigh. Rippling AI answers questions on live company data across HR, IT, and finance and takes action inside Rippling, inheriting each user’s existing permissions.
What makes it different from Carly: it is a migration, not an add-on. Carly works with the Gusto you already run.
Best for: Growing companies that also want IT and device management in the same system.
Pricing: Custom quote
6. Zapier
Trigger-action automation across thousands of apps, with AI steps for drafting and parsing.
What makes it different from Carly: Zapier’s public app directory does not list Gusto today, so a Zap can react to the offer email or the calendar event but cannot read Gusto itself. Every Zap is plumbing you build and maintain. See Zapier alternatives.
Best for: Simple email-to-spreadsheet or form-to-Slack steps around your HR process.
Pricing: Free plan; paid from ~$19.99/month
7. Make
A visual canvas with branching, loops, and data transforms. A community-built Gusto app, made by neither Make nor Gusto, adds modules for creating employees, jobs, and timesheets.
What makes it different from Carly: more control and more canvas to build and debug, with a third-party connector sitting on your payroll data. Carly trades the canvas for plain words. See Make alternatives.
Best for: Technical operators who want to wire onboarding steps by hand.
Pricing: Free plan; paid from ~$12/month

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."
