Toggle the layers on and off — just like in the real weekly calendar.
Context
No hour without context.
Whatever you track automatically belongs to a project, client, and service — no cleanup at month end.
Service and rate attached
Every session knows its service. Reports and billing match later.
Dictate instead of typing
Dictate tasks and notes right in the tracker — Klausi transcribes live.
Client and project automatic
The assignment is set from the start — not only when you write the invoice.
Time, project, and invoice — in one place.
Free: timer, calendar & reports · Pro: automatic invoice & export
Recap notes
Say what happened.
The rest documents itself.
After you stop the timer, Klausi asks for a short recap. You speak — Klausi transcribes live. The note is automatically attached to the time entry and later sits in the project under “Notes”. No typing, no copy-paste, no lost context.
- Recap dialog after the timer stops — speak instead of type
- Transcribed live, saved right on the time entry
- Shows up in the project under “Notes” — with date and duration

Frequent questions
Questions about time tracking.
Who is Klausi for?
For the self-employed and small teams who bill their time — freelancers, creatives, consultants, agencies. If your hours should turn into invoices, you’re in the right place.
What’s free — and what costs extra?
The core is free forever: timer, weekly calendar, and reports. Pro features like the automatic invoice draft and PDF export are part of the paid building blocks. Details on the pricing page.
Can I switch from Toggl, Clockify & co. — do my old entries come along?
Yes. You can import your existing entries via CSV — Klausi detects the columns automatically and creates projects and clients along the way. There’s no lock-in: you can export again anytime.
How fast am I up and running?
In under a minute. Create an account, start the timer — attach project and client with one click. No setup, no onboarding marathon.
How do tracked hours become an invoice?
Every session knows its project, service, and rate. From that, Klausi builds an invoice draft with finished line items in the finance area — you review it and export it as a PDF, instead of piecing everything together by hand at month end.
What if I forget to start the timer?
No problem. You can create or correct any entry manually at any time. The timer is the shortcut, not a requirement — your time tracking stays complete without it.
What happens to my data — and can I get out again?
Your data is stored GDPR-compliant on EU servers. No lock-in: you can export your time and invoices anytime. What you capture in Klausi is yours.
