Keep the outcome and the steps together, so you can pick up where you left off.

Sample garden project in Carbon, with the next action followed by the remaining steps in order — A small project, broken down into actions you can actually do.

A GTD workflow

From “remember this” to “done”.

Capture first. Decide what it means when you have time to think.

01 / Capture

Get it out of your head.

Add “sort out the garden” to your inbox. You don't have to choose a project or a date yet.

Carbon inbox containing Sort out the garden alongside a few other sample ideas — The inbox holds ideas until you're ready to clarify them.

02 / Organize

Make the next step clear.

Turn the idea into a project: “Plant the balcony garden”. Start with “Measure the planter space”, then order the steps that follow.

Plant the balcony garden project with Measure the planter space first, followed by choosing pots and buying seedlings — Use a sequential project when one action needs to come before another.

03 / Plan

Fit the work to your day.

Choose a few actions for today and add time estimates. Leave room for the rest of your day.

Carbon Plan view with a short list of sample actions and their time estimates — A short daily plan helps you see what you've taken on.

04 / Review

Give quiet projects some attention.

Check the projects due for review. Look at what has moved, what is waiting, and whether each project has a useful next action.

Carbon Review view showing sample projects ready for a progress check — Review is a chance to rethink the plan, not just tick off tasks.

Local use

Free · no account

Keep tasks in this browser. Work with locally stored tasks without a sync server.

Use the same browser and address to return to your data. Clearing browser storage removes local data. Uncached images and online integrations need a connection.

A few useful answers.

Do I need an account?

No. Choose Try locally to start in your browser. Create an account if you want a hosted workspace.

What works without a connection?

You can work with tasks stored on your device. Sync, AI and other online integrations need a connection. Images and attachments need to be available locally before you go offline.

Where is my data?

Local use stores data in your browser at the address you use. A connected workspace also sends data to its sync server. See the privacy policy and data guide for details.

Can I run my own server?

Yes. The Docker guide covers setup. You are responsible for operating and backing up your server.

How do I return to my hosted workspace?

Open the workspace address you received when you signed up. You sign in at that address. Bookmark it to return.
