How it works
- 1
Track from your menu bar.
Add a client and project, then start timing with one click. The menu-bar icon shows the running time.
- 2
See what's billable.
Rates turn into amounts automatically. Review under Time Entries and Reports; export to CSV for invoicing.
- 3
Sync to Notion (optional).
Click Connect to Notion — Seiche adds a ready-made workspace and keeps it in sync, automatically.
Your hours, live in Notion
One click connects your Notion workspace — no tokens or copy-pasting.
Seiche creates a Seiche page with three linked databases: Clients → Projects → Time Entries, with hours and billable amounts on every entry.
Your Mac stays the source of truth; Notion is a live, shareable mirror.
A word on privacy
Seiche has no account and no analytics. Your data stays on your Mac unless you connect Notion, and even then your access token is only handled transiently during connection.
