Managers pay for the app the staff actually uses — mobile scheduling, time clocks, and swap workflows — because a rota that needs a desktop is a rota nobody checks.
REPLACEMENT BRIEF
hr
Can AI replace When I Work?
A shift schedule with availability and swap approvals is a buildable roster — calendar plus a state machine. The product's moat is the hourly-workforce layer: mobile apps, time clocks, notifications, labor-law edge cases, and payroll connections — the operations, not the grid.
Build a small shift schedule, availability form, and swap approval workflow, maintain approvals and records, and export data without calculating payroll or making employment decisions.

the prompt
Catalog estimateBuild a personal replacement for When I Work in an empty repository. Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, and Docker Compose; do not offer alternative stacks. The core loop is: build a small shift schedule, availability form, and swap approval workflow, maintain approvals and records, and export data without calculating payroll or making employment decisions. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Implement employees, teams, roles, documents, leave requests, equipment, onboarding tasks, and acknowledgements. Use least-privilege roles and log every read or change to sensitive records. Add approval workflows, expiry reminders, export, retention, deletion holds, and encrypted backups. Keep compensation fields optional and never calculate payroll, taxes, benefits, or statutory filings. Provide a data dictionary and explain which fields should not be stored without legal review. Ship Docker Compose, health checks, disaster recovery, and an emergency-access procedure. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Deliberately leave out payroll calculation or money movement. Deliberately leave out automated hiring decisions or applicant scoring. Deliberately leave out tax, benefits, immigration, identity, and global-employment compliance. Finish by running the tests and listing the exact commands used.

questions
Can AI replace When I Work?
Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: mobile apps, time clock, notifications, scheduling edge cases, and support, payroll rails. Validate the prompt against your own acceptance criteria before committing.
How much does When I Work cost?
When I Work is listed at about $2.50/month (Essentials, checked 2026-07-31), or $30 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.
What do I lose by replacing When I Work?
Honestly: mobile apps, time clock, notifications, scheduling edge cases, and support; payroll rails; tax and labor-law compliance; benefits integrations; identity checks and global employment infrastructure. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to When I Work?
Yes — Frappe HR (Active open-source human-resources and payroll application built on Frappe.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
