Already Using Gusto? Add AirAssist for HR Policy AI in Slack, Teams, and Everywhere Else

If you are reading this, you are almost certainly a Gusto customer already - likely running payroll, benefits, and small-business HR inside Gusto. Gus (Gusto's AI assistant, built using Humanloop evals and rolled out through 2025-2026) does a lot of small-business HR tasks well: payroll and benefits Q&A, report generation, time-off approvals, raise assignments with a "summarize-confirm-execute" pattern, and plain-English compliance explanations.

This page is not about replacing any of that. AirAssist is the handbook-grounded HR policy AI that layers on top of your existing Gusto setup and extends the conversational surface into Slack, Microsoft Teams, your intranet, and anywhere else your team already works - surfaces where Gus does not have a documented first-class end-employee deployment.

The real question for Gusto customers is not "which AI is better." It is: when an employee asks "what is our policy on working from another state?" or "how does our parental leave work with the benefits carrier?" in Slack at 9:12am, what answer comes back, is it grounded across every policy document you actually maintain (not just Gusto payroll/benefits data), does HR have a clean audit trail of it, and did the employee have to leave Slack to get it?

That is the gap AirAssist was built for. Gusto stays where it is - payroll, benefits, compliance. AirAssist sits on top of your handbook and up to 200 other HR documents as the policy-answer layer for every channel your team already uses.

Gus's primary surface is the Gusto web app. There is no documented first-class Slack or Microsoft Teams deployment, no intranet widget, and no SharePoint integration. For Gusto customers whose teams live in Slack or Teams, that is a real gap.

AirAssist is HRIS-agnostic by design. It integrates with Gusto (and every other major HRIS) to personalize answers with employee profile, location, role, and department - but it is not anchored to any single HCM. That distinction matters:

• First-class Slack deployment - AirAssist runs as a native Slack bot. Employees ask policy questions in the channels and DMs they already use all day.
• First-class Microsoft Teams deployment - same experience inside Teams, for organizations standardized on M365.
• Intranet / SharePoint / web widget - embed AirAssist wherever your policies already live.
• Future-proof - if your organization grows past Gusto's SMB sweet spot and migrates to Workday, Rippling, ADP, BambooHR, or anything else, AirAssist comes with you. Gus does not.
• Knowledge scope beyond Gusto data - AirAssist reads your handbook, addenda, benefits carrier PDFs, training manuals, and custom Q&A directly. Gusto's handbook-update feature is still on the roadmap, per public materials.

For most AirMason customers on Gusto, AirAssist and Gus end up doing different jobs on different surfaces. Gusto handles payroll runs, benefits enrollment, and time-off approvals inside the Gusto app; AirAssist handles "what is our remote-work policy for part-time employees in Texas?" in Slack, grounded in 200 documents, with a citation and an HR-reviewable audit trail.

Gus answers questions from Gusto-native data (payroll, benefits enrollment, compliance categories) and provides plain-English explanations of compliance context. Gus does link to sources, but Gusto explicitly disclaims accuracy and asks users to verify. A dedicated handbook-update feature is still on the roadmap per public materials. Handbook-grounded policy Q&A with inline citations and an audit trail is not Gus's core design.

AirAssist takes a different approach. You can load up to 200 source documents of any type, from anywhere - and they do not have to be handbooks. Some examples of what AirMason customers actually load:

• The employee handbook itself, plus state and federal addenda
• Benefits carrier PDFs straight from Anthem, Blue Cross, Guardian, your 401(k) provider
• Training manuals, onboarding docs, team playbooks, role-specific SOPs
• Legal policies (anti-harassment, whistleblower, IP), compliance memos, safety protocols
• Culture guides, values documents, DEI materials
• Custom Q&A for company-specific edge cases

Supported formats include PDF, Word, PowerPoint, Google Docs, and HTML. You do not have to centralize any of that inside Gusto or rewrite it into another format - just upload and AirAssist reads it in place. As policies change, you replace the source document; AirAssist's answers update automatically.

This matters because HR policy knowledge does not live in one system. It is scattered across the handbook, benefits provider PDFs, compliance memos, training materials, and institutional knowledge that lives in people's heads. AirAssist lets the content stay where it already lives and grounds answers across all 200 sources at once. Gus is anchored to Gusto data.

For HRIS context, AirAssist pulls employee profile data (location, role, department, tenure, manager) from Gusto or any other major HRIS you use - but its knowledge base is not limited to what lives inside the HRIS.

If you do not currently have a polished handbook, a free AirMason handbook audit can surface gaps before you deploy any AI assistant on top of your policy content.

HR and legal teams need to know what an AI told an employee, who asked, and whether the answer was correct. This becomes critical the moment an employee references a chatbot response during a leave dispute, a wage question, or any conversation with real legal exposure.

AirAssist records a full audit trail of every answer - the question, the response, the source policy section, and any HR edits or overrides. HR admins can review conversation history, adjust future answers for the same question, download reports, and prove compliance with documentation if needed. Every answer is editable before or after it is shared, and AirAssist learns from those edits for next time.

Gusto logs system actions and Gus links to source data for user verification. However, a dedicated per-answer editorial audit trail and HR override flow for Gus responses is not a documented primary feature, and Gusto explicitly disclaims AI accuracy. For Gusto customers that want an audit-ready policy AI with per-answer review and override, AirAssist was designed around that requirement from day one.

Gus is bundled with your Gusto plan (Simple ~$40/month + $6/employee; Plus ~$80/month + $12/employee) at no separate fee - a genuine benefit you are already paying for. AirAssist is not a replacement for any of that. It is an incremental layer specifically for handbook-grounded policy Q&A across up to 200 documents, in the channels your team already uses.

AirAssist pricing is $4.20 per employee per year on top of your existing Gusto subscription. For a 100-person Gusto customer that is $420 per year to add a Slack-and-Teams-native, handbook-grounded policy AI with a full audit trail - roughly the cost of a single legal review engagement and dramatically less than the hours your HR team currently spends answering the same repeat policy questions over and over.

Many AirMason customers on Gusto run both side by side: Gusto stays the system of record for payroll, benefits, and compliance, and AirAssist sits on top of the handbook plus 199 other documents answering policy questions wherever employees already work. If your organization ever migrates off Gusto (often as you grow past the SMB tier), AirAssist comes with you - no rebuild, no retraining the AI on a new HCM.
