Stay with the person
An add-on answers a human task. The person remains the one doing the work. The software takes the extra steps, not the attention.
Design, craft, engineering
Add-ons that maketools people already usemore productive.
Zecro is a design-engineering studio. We build plugins that connect a person to the tools they already open, and to the services a task needs next.
Why
Productivity stays with the person.
A workday already has a shape. Someone opens a tool, reaches for another service, and tries to keep the thread. Greater productivity is a shorter path along that thread.
We design and engineer the add-on that holds it. The host stays the place of work. The person stays the one doing it. The plugin carries the connection.
The connection
A person, the tool already open, and the next service.
The add-on is the link between them. It stays with the person, inside the host, and reaches the service the task needs.
That link is what Zecro designs and builds.

Enhancing a product
Making another product more capable.
Meet the tool
The plugin belongs inside the host. People keep the product they already know, and the new capability shows up there.
Reach the service
When the task needs another system, the add-on makes that handoff part of the same work, instead of a separate errand.
How we work
A workflow for building on platforms.
- 01
Learn the workday
We start from the hour the work happens, and from the person in it.
- 02
Name the host
The tool they already open is the place the add-on will live.
- 03
Map the connection
Person, tool, and service, and the step where the thread currently breaks.
- 04
Design and build
Interface and engineering together, so the add-on is clear and holds.
- 05
Fit the real day
We judge it by whether the workday moves.
The practice
Three principles, for every add-on.
- 01
Native to the host
It lives in the product already open, in the language of that product.
- 02
Crafted for clarity
The next action is obvious. Type, measure, and behavior are decided together.
- 03
Built for real workdays
Made for the hour the work actually happens, and for the person who has to repeat it.
