Cardboard Concept Mobile app
Hemal Singh
Your video editing tools. In your pocket.
Extending Cardboard beyond the desk so creators and teams can edit, review, and collaborate wherever they are.
Project Overview
Cardboard already works on the web. So why mobile?
Cardboard's web experience is built for serious editing work. A large screen gives editors room for the timeline, media, controls, and longer sessions. Mobile has a different job.
I explored how Cardboard could support the moments that happen between desktop sessions: reviewing a cut, responding to a teammate, making a quick AI edit, checking a version, or approving a video.
The goal was to make Cardboard available without asking users to treat their phone like a smaller desktop editor.
Ai Char Interface where user can edit videos with in chat no editing skills needed.
The problem
Video work does not always happen at a desk.
A creator may be traveling.
An editor may receive feedback away from their laptop.
A teammate may need to approve a video quickly.
A creator may want to make one small change before publishing.
In each case, the work can wait until the user gets back to a laptop.
Context Mapping
Why I did it
I wanted to understand when someone would actually open Cardboard on a phone.
Instead of starting with features, I started with situations.
Scenario 01: Traveling
An editor gets a message:
"Can you tighten the intro?"
They do not have their laptop.
They open Cardboard, ask AI to shorten the intro, review the result, and reply.
Scenario 02: Team feedback
A teammate leaves a comment at 01:24.
The editor receives the notification while away from the desk.
They open the video, jump directly to 01:24, watch the section, and respond.
Scenario 03: Last-minute approval
A client needs a video approved before publishing.
The user opens the project, watches the latest version, checks the comments, and approves it.
Scenario 04: Creator workflow
A teammate leaves a comment at 01:24.
A creator records content on their phone and wants to make a quick version for social media.
Instead of waiting for a laptop, they can start the process immediately.
Key finding
The strongest mobile use cases were not long editing sessions.
They were short moments where waiting creates friction.
That became the basis for the mobile experience.
Impact
The project was designed to solve an access problem, not replace Cardboard Web.
Because this is a concept project, I am not presenting made-up conversion, retention, or time-saved numbers.
Instead, the impact can be measured against the original product goals.
01. More access
Cardboard can be available when a laptop is not.Cardboard can be available when a laptop is not.
02. Faster responses
A user can respond to feedback immediately instead of waiting for the next desktop session.
03. Better mobile use of AI
Natural-language editing reduces the number of controls users need to find on a small screen.
04. More continuous collaboration
Comments, timestamps, approvals, and version history can follow the user outside the desktop workspace.
05. The larger product opportunity
If validated with real users, Cardboard Mobile could make the product useful across more parts of a creator's day without taking away the desktop experience that professional editing still needs.
