What SI WorkHub does

Kanban & Dependencies

Projects, sprints and delivery on drag-and-drop boards — blocked-by links surface what's holding work up.

Invoices

Billable hours → professional PDF invoice in seconds. Clients, rates and history tracked.

Time Tracker

Billable entries with rates per project — the record your invoice is built from.

Light CRM

Contacts, companies and follow-ups tied to projects — relationships, not just tasks.

Workflows

Repeatable processes as checklists and templates — onboard clients the same way every time.

Project Tracker

Milestones, blockers and health across everything you're running.

Work Docs

Proposals, specs and contracts attached to projects — readable and editable in-app.

Meeting Notes

Record calls, get minutes and action items — linked to the client and project.

AI Hub

Specialist work agents, weekly reports and workflows — grounded in your projects, meetings and docs.

Honest pricing

  • Free: boards, time tracking, CRM basics
  • Pro $5.99/mo — invoices, dependencies, AI reports
  • Business $14.99/mo — unlimited AI Hub, everything
  • vs Asana ~$11/mo per seat — flat price, never per-seat

Private by design

  • No accounts, no trackers, no ads — data stays on your device
  • On-device AI first; cloud only with your own API keys and explicit consent
  • Keys in Keychain / Android Keystore — never logged, never synced
