Plan projects
Get tasks and decisions out of your head and into a plan, tailored with the exact amount of detail that matters to you.
The app for project cars
Project cars live here.
A better way to plan, track, and remember all of the details for your car projects.
Most project cars live across notes, spreadsheets, camera rolls, receipts, and memory. Assembly brings the important parts together without turning your project into admin work.
Available now
Assembly for iPhone
Desktop access available in May 2026. Android app coming late Spring 2026.
Centralize your project info
Built for the way project cars actually happen.
Assembly is built for the full lifecycle of a project car—not just documenting completed work, but planning what’s next and tracking progress as it happens.
Track parts
Capture details about parts you plan to buy, have on the shelf, or already installed. Add only the details that matter to you and capture more over time.
Capture notes & photos
Drop in all of your other thoughts, measurements, reference documents and anything you’ll want to look at in the future. Text, links, photos, whatever you need.
Build a living history
We automatically assemble the history and evolution of your project as you install parts and complete projects.
Organization doesn’t have to be hard work
Made for the tinkerers
Assembly gives each car a dedicated workspace for projects, parts, notes, specs, and history.
It is flexible enough for quick thoughts, structured enough to become useful later, and calm enough to stay out of the way.
