Power-Up for Trello

Time tracking in Trello — just say what you did.

Log time on any card with a timer or by hand, see where your team's hours go, or tell your AI assistant “log 2 hours on the landing page” — Tacto does the rest.

Everything your team needs to track time

No spreadsheets, no switching apps. Time lives on the cards it was spent on, and reports are one click away.

⏱ On every card

Start a timer or log it afterwards

Every card gets a Worklog. Press ▶ and keep working — the timer runs even if you close the card or the browser.

Any format — 1h 30m, 90m, 1:30 or just 1.5
Estimates — see how much of the plan is already spent
Badges on the board show totals and who is working right now

📊 Reports

See where the hours go

One button on the board opens reports for every board you can see.

Calendar — logged time day by day
Timeline — who worked on what, cards by days
Analytics — totals, change from the previous period, team, plan vs actual
History — who changed or deleted what, with restore
Filters — boards, members and any period

⬇ Export & import

CSV in a click, history moved over

Pick the columns and download CSV, Excel or PDF for invoices or payroll. Switching from Chronos, Toggl, Clockify or a spreadsheet? The import wizard reads the file, finds the cards and people and shows what is left out.

💼 Finance

Hours turn into an invoice

For teams that bill clients by the hour. An admin groups boards by client and sets rates — Tacto counts the billable amount and builds a PDF invoice.

Rates with start dates — for the workspace, a person, a client or a board
Billable or not — on every entry, with defaults per board and client
Admins only — the team sees its hours, not the amounts

🤖 AI assistant

Your assistant keeps the timesheet

Connect Claude, Cursor, ChatGPT or any assistant that speaks MCP. Then just talk:

“log 3 hours on the redesign, fixed mockups after review”
“how much did I track this week?”
“create a card in Backlog and log 2 hours to it”

By default it shows exactly what it will log and waits for your “yes”; confirmations are set in Tacto. claude.ai, ChatGPT and Claude Code connect with a Trello sign-in — no key; for other assistants a personal key takes a minute. Either one is revoked in one click.

Built for teams

Time tracking follows your Trello workspace — the right people see the right boards.

👥

Guests stay outside

Board guests from outside your workspace don't see your team's time unless an admin lets a specific guest in.

🔐

Secure by default

Trello tokens are encrypted, API keys are stored only as hashes and shown once.

🧹

Your data, your call

“Remove personal settings” erases everything personal in one click. Entries stay with the team.

💰

Clients, rates and invoices

Bill clients by the hour: billable amounts for admins, invoices in a click. The team sees only its hours.

Up and running in two minutes

No account to create — Tacto uses your Trello identity.

Add the Power-Up

On your board: Power-Ups → search “Tacto” → Add.

Allow Trello access

Once — so your team list and new cards stay in sync. Tracking works even before that.

Log your first hour

Open any card, press ▶ or type 1h in the Worklog.

Questions

Do I need a separate account?

No. Tacto works with your Trello account. Trello itself tells Tacto who you are and which boards you are on.

Who can see the time I log?

Members of the board who belong to its Trello workspace. Guests from outside the workspace don't see time tracking unless a workspace admin lets a specific guest in. More about visibility.

Which AI assistants work with Tacto?

Any assistant that supports MCP over HTTP: claude.ai, Claude Desktop and Claude Code, ChatGPT, Cursor, Windsurf, VS Code with Copilot, Zed and your own agents. Setup guide.

Can I bring my history from another tracker?

Yes. Export a CSV or Excel file from Chronos, Toggl, Clockify, Harvest, Jira or your own sheet and open Reports → Export → “Import a file…”. The wizard maps the columns, finds cards and people and offers to create missing cards.

Does the timer stop if I close Trello?

No. Timers run on our server, so they keep going until you pause or stop them on the card. “Running timers” in the Tacto menu on the board shows where they are running.
