Build your own project manager with Claude

Every project tool I tried was built for a team of thirty. I'm a team of one.

I'd sign up for whichever one everyone was using, Notion, Asana or Trello, and spend a weekend colour-coding a board. Two weeks later I was spending more time updating the board than doing the actual work. The tool had become the job.

What finally worked was simple. I built my own in an afternoon with Claude. No code, no subscription and no features I don't use. It's shaped exactly like my week. Here's how to do the same.

1. Write down how you actually work before you open Claude

Use a notebook, not an app. Write down how work really moves through your days, not how you think it should. Ask yourself:

• What do you actually track? Tasks, projects, "someday maybe", follow-ups. Pick the two or three that matter and ignore the rest.
• What are your real stages? Most solo work is just idea → doing → done. You probably don't need seven columns.
• What do you look at first thing in the morning? That's your home screen. Build that one view first.
• What do the big tools nag you about that you don't care about? Due dates on everything, story points, sub-tasks inside sub-tasks. Leave all of it out.

Ten minutes of this gives you a one-page plan that's more useful than any template, because it's based on how you work.

2. Describe it to Claude and let it build

Now you just talk. You don't write any code. You describe what you wrote down and Claude builds it. I've done it two ways:

• A single-file tool. Ask Claude to build a small web app in one HTML file that saves to your browser, with no account. Something like: "Build me a minimal personal project tracker as a single HTML file. Columns: Ideas, Doing, Done. I can add cards, drag them between columns, and it saves in my browser. Keep it calm and clean, dark, not busy." You'll get a working tool you can open from your desktop.
• A Claude Project that plans your week. Set up a Project with instructions on how you like to work. Each morning, paste in your tasks and let it plan the day, flag what's falling behind and cut what doesn't matter. It works more like an assistant than an app.

Either way, changing it takes one sentence. "Make the Done column collapsible." "Add a Today view." "This feels cluttered, simplify it." Claude rewrites it on the spot.

3. Use it for a week, then change it

Don't polish it at the start. Use the rough version for a week and notice what annoys you, the moments where you sigh and reach for something else. Each of those is your next prompt. Because you built it, you're never stuck with someone else's idea of how you should work. You just change it.

Mine still isn't pretty. It has four things on it and nothing else. But I open it every morning, I actually use it, and it costs me nothing. The tool works for me now, and not the other way around.
