01
AI co-worker
Every customer gets a dedicated cloud agent. Skills, scheduler, connectors, and your MCP — collapsed into a Slack DM.
01
Dedicated cloud agent
One agent instance per customer. Own skills, own scheduler, own connectors, commercial LLM underneath. You talk to it from Slack.
02
Skill files
Markdown playbooks the agent follows. Save, version, and share across the workspace. Slack runs them like built-in features.
03
Scheduler
Cron-style tasks: "first payroll of the month", "first Monday", "quarterly". Pause, unpause, run now.
04
Event-driven sequences
Subscribe to hires, terminations, comp changes, document uploads, invoices, payroll approval. The agent runs when the event fires — not when someone remembers to ask.
05
Customer-managed connectors
Point the agent at Carta, Notion, Google Drive, or any MCP the directory offers. Auth is yours; Winslow never holds the vendor password.
06
1,000+ integrations
Pipedream-backed directory. The agent discovers what's connected and uses those tools alongside native Winslow tools.
07
Personas
Collection-scoped AI identities with their own knowledge base, tone, and behavior.
08
Agent acts as the employee
Slack identity maps to the employee record. Scopes, field filters, and audit identity are the acting human's — not a god-mode service account.
02
Payroll
Multi-state payroll. Run it, file it, forget it. Off-cycle runs are free, every time.
01
Run payroll in all 50 states
Federal, state, and local tax accounts handled. Hire in a new state, Winslow opens the account before payday.
02
W-2 and 1099 generation
Generated, distributed, and e-filed. Year-end is a non-event.
03
Contractor payments
1099 contractors on the same schedule and dashboard as W-2 employees. No second tool.
04
Contractor invoices
Contractors submit invoices (including from Slack). Managers approve; approved invoices flow into the next payroll.
05
Off-cycle payroll runs
Bonuses, corrections, terminations, spot payments. No per-run fee, ever.
06
Termination payroll
Final pay as its own off-cycle run — kicked off when the termination lands, not as a manual extra cycle.
07
Garnishment processing
Child support, levies, defaulted-loan orders — withheld and routed to the right agency automatically.
08
Direct deposit
ACH by default.
09
Auto-approve with variance gates
Compare this run to the last one. Net-pay deltas, missing invoices, unfamiliar deductions — auto-approve when it matches your rules, flag when it doesn't.
10
Approval deadline reminders
D-3 / D-1 / D-0 reminders to whoever can approve. Employees don't miss payday because someone forgot to click.
11
Approval workflow you can program
Approving payroll kicks off an agent process. Out of the box: notifications, exports, anomaly review. Customize with a skill file.
12
Recurring adjustment templates
Gym stipends, bonuses, allowances — define once, apply on every matching run. One-offs still exist for spot payments.
13
Pre-tax deductions
FSA, HSA, commuter, parking, dependent care — all handled at the deduction layer.
14
Post-tax deductions
Custom withholdings, charitable matching.
15
Time-off accruals on every run
PTO, sick, parental, custom leave types — accrued and surfaced on every paystub.
16
Unpaid leave calculations
Automatically calculate payroll adjustments for unpaid leave.
17
Reimbursements
Expense, mileage, equipment, per-diem — paid through payroll or off-cycle.
18
Paystub access in Slack
Employees DM Winslow, get their paystub. "You got paid" notices go out on every run.
19
We do not support hourly workers at this time
We manage payroll for salaried employees in the United States only at this time.
03
Benefits
A network of brokers for competitive plan sourcing. Enrollments and life events managed without tickets. AI-supported because that's what your employees expect now.
01
Broker network for plan sourcing
A network of brokers shops your plans for competitive pricing — small group, level-funded, large group.
02
Health insurance — small group, level-funded, large group
Plans for every team size. You don't change vendors when you outgrow a tier.
03
Dental and vision
Standard ancillary lines, sourced and administered.
04
Open enrollment in Slack
Plans presented as cards in the thread. Employee picks, confirms dependents, done. Five minutes.
05
Full OE lifecycle
Plan catalog → selection → open enrollment → elections → broker import → finalize → payroll deductions. One flow, not six tools.
06
Plan recommendations
HR flags recommended plans. The agent walks the employee through SPD documents, dependents, and options. Suggests, doesn't decide.
07
Qualifying life events
Marriage, new dependent, address change, loss of coverage — file, approve, open a special enrollment window. No ticket.
08
SPD access for enrolled plans
Employees (and their agent) can pull the summary plan description for the plans they're on.
09
Enrollment e-signature
Capture a signature on OE submit. Audit-logged with the election.
10
Life-event processing
New dependent, address change, qualifying event — triggered by HRIS, processed without a ticket.
11
Compliance and Filings
Winslow has your back in all 50 states.
12
Carrier integrations
Direct connections to the major carriers. Enrollments and demographic changes sync without EDI tickets.
13
Renewal calendar with quotes
60 / 30 / 15 days out — options sourced, recommendations sent, communications drafted.
14
Payroll Integrated
Benefits deductions integrated directly into your payroll runs.
15
Enrollment reminders
Open / close / finalize notices to employees and admins. Opt-in per channel.
04

01
Employee records with custom fields

Real-time reporting
Headcount, comp distribution, retention by team, attrition. Ask in natural language; get a table. Pivot-able, exportable.
15
Open data model
Real, writable database. Read it, write it, build on it. No vendor lock on your data.
16
Headcount planning
Open reqs, projected starts, replacement vs incremental. Linked to comp bands.
17
Manager dashboards
Direct report list, comp history, time-off requests, recent changes. Lives in Slack, mirrored in admin UI.
05
Tax & compliance
Notices opened, registrations filed, deadlines hit. Agents handle 10,000+ jurisdictions so you don't.
01
State tax registration
SUI, withholding, unemployment accounts opened automatically when you hire in a new state.
02
Federal, state, local filings
941, 940, W-2s, W-3s, state quarterly returns — on time, every cycle.
03
Tax notice resolution
Agent reads the notice, classifies it, acts. You see a summary, not a stack of envelopes.

Captured from the state, applied to the next run, back-corrected if applicable.
05
I-9 verification

Slack

DM Winslow anything
PTO, paystubs, benefits, onboarding tasks, policy lookup. Sourced from your data and policies, not the open web.

Plan cards rendered in chat. Five-minute flow per employee.
07

Missing W-4? Winslow asks, employee uploads in-thread, HRIS updates.
08
File attachments in chat

Payroll, invoices, time off, benefits, billing. Per-person preferences, MCP-writable. Some notices are mandatory.
11
Analytics on questions
HR sees what employees are asking. Trending topics, unanswered questions, time-to-resolution.
07
Architecture for agents
If you're here for a reason, this is probably it. MCP, skill files, OAuth, events. Your agents drive Winslow as a first-class consumer.
01
Public MCP server
Claude, ChatGPT, Cursor, Lovable, Bolt — 185 tools, full read/write, same auth as the admin UI. No bespoke integrations.
02
Skill files for custom workflows
Drop them into your Winslow workspace. The Slack employee chat runs them like built-in features.
03
Winslow Events + outbound webhooks
Hire, terminate, promote, comp change, leave request, invoice, payroll, QLE — persisted, subscribable, POSTed to your stack (Zapier, custom HTTPS).
04
REST API + OAuth
Standard auth, paginated. "Login with Winslow" for apps that act on behalf of a user. MCP keys do not work on REST — by design.
05
Writable system of record
No black-box objects. Read, write, audit, export. Your HR data is yours.
06
Custom menu items in admin UI
Tools you build externally register as menu items inside Winslow. Lives where the team already works.
07
Generative-UI tools in chat
When an employee says "I want to do X," Winslow launches your tool inline. Same pattern as Claude artifacts.
08
Vibe-code support
Point Lovable, Cursor, Bolt, Replit at the MCP, build a custom HR app in an afternoon. Install it in the sidebar. We do not ship it for you on purpose.
09
Native audit log on every action
Agent-driven actions are auditable as first-class events. Same trail as human actions.
10
<code>/llms.txt</code> + <code>/AGENTS.md</code> + <code>/for-your-agent</code>
Machine-readable canonical summary at the edge. Your agent reads it in one fetch, no scraping required.
11
get_api_docs
The MCP documents itself. Call one tool for OAuth, REST, MCP, auth, and a quickstart recipe.
08
Security & trust
Boring on purpose. The page your security team sends back with no questions.
01
SOC 2 Type II
Annual audit. Report available on request behind a short form.
02
Encryption in transit and at rest
TLS 1.3, AES-256. Keys rotated quarterly.
03
Layer-cake permissions
Menu, tab, field, API route, MCP tool — same checks, same order, humans and agents. All filtering is server-side.
04
Role-based access control
Granular scopes. Audit on every permission change. Terminated employees lose access.
05
Field-level access
Custom properties declare who can see and who can edit. A manager's MCP session cannot exfiltrate a field they cannot see in the UI.
06
Full audit log export
Every employee-data change. Exportable to your SIEM.
07
Data residency
US-only.
10
Pricing
100% usage-based pricing. $0 per employee per month, ever — you pay for what your team uses, not for who you hired.
Free
$0 / mo
Up to $100 in co-worker credits. No credit card, and they never expire.
Team
$40 / mo
Standard usage, regardless of headcount. Payroll, benefits and HRIS included.
Global payments and EOR cost extra. Everything else is in the $40. Full pricing.

What we don't do
Honest list. If one of these is a dealbreaker, save us both a call.
- We are not a PEO. No co-employment. (If you want one, JustWorks is the right call.)
- We do not have a Microsoft Teams employee experience. Slack only.
- We do not run a marketplace of third-party apps. We expose an MCP and let you build what you need.
- We do not sell separate IT or finance products. If you want Rippling-style device MDM or spend management in the same suite, we are not the answer.
- For now, we don't do hourly workers (coming soon).
- We don't charge you for every module you add. It's one price for everything we offer.
- We do not gate AI usage behind seat counts. There is no "AI add-on." It is the architecture.
- We do not negotiate multi-year lock-ins. Annual contracts or less.

For your agent
