Know where the hours went.
Diurna is time tracking, expenses and profitability reporting for small studios. Track time in a week grid built for people who actually fill one in — then find out what a project really cost.
No credit card, because there's nothing to buy yet. We'll email you when Diurna opens up.

Built as a Harvest replacement
Screen by screen, against a live Harvest account.
Small studios, not enterprises
Budgets, cost rates and utilization — no seat sprawl.
Talks to Claude
An MCP server instead of a chat box bolted on the side.
Track
A timesheet people will actually fill in
- Week grid with spreadsheet-style cells, per-cell notes and a running total.
- Copy last week's rows in one click, or add a row as you go.
- A timer in the sidebar that follows you around the app.
- Day view when you want to write a longer note against an entry.

Spend
Expenses, with the receipt attached
- Weekly expense list with your own categories.
- Receipts stored privately and served through signed links.
- Billable and invoiced flags that flow into reports and invoices.

Report
What the project actually cost
- Profitability: billable value measured against hours × cost rates.
- Quarter, calendar year, fiscal year and all-time presets.
- Rounded and raw hours side by side — no arguing about which is which.
- Client report links: read-only, no login, revocable at any time.
Reports — profitability

Bill
Invoices and estimates, then out to Xero
- Uninvoiced billable time becomes invoice lines at the right rate.
- Estimates that convert to an invoice when they're accepted.
- Xero hand-off by CSV or copy-paste — matched to Xero's import template.
- Entries get stamped and locked once invoiced, so nothing is billed twice.

Ask your timesheets a question
Diurna ships an MCP server, so Claude can query your tracked time directly — no exports, no copy-paste, no chat box bolted onto a reports page. It runs locally today. The hosted endpoint is in progress, and waitlist members get it first.
Things you can ask
- “How many hours did we log on SearchX in July?”
- “Which projects went over budget last quarter?”
- “Create a client report link for last month, with amounts.”
- “What's still uninvoiced across all clients?”
Tools it exposes
- query_time_entries
- report_summary
- uninvoiced_summary
- query_expenses
- profitability_summary
- list_clients
- list_projects
- list_tasks
- create_report_share
Diurna isn't open yet
We're finishing the multi-studio version. Leave your email and we'll tell you the day you can sign up — and what it costs, before anyone else.
