THE PLATFORM

From a teaching idea
to an editable resource.

01

Create with context

Start from the learning stage, subject and teaching intention. Use conversation or guided activity formats as a starting point.

02

Adapt the material

Edit instructions, illustrations, colors and block order. Keep teachers in control of the final activity.

03

Build a reusable library

Save, favorite, duplicate and reopen resources for another class or lesson.

04

Export for classroom use

Preview and export to PDF or Word. Text stays editable in Word; illustrations are images.

IN OPERATION SINCE 2025

Built with teachers.
Rooted in everyday use.

Founded in 2025 as Projeto Combinado, Entrefio serves 216 accounts, including 188 paying accounts and 28 in its incentive program for pedagogy students. This adoption grew through use of the platform before investment in brand promotion. Teachers across Bahia use the product, several municipal governments support the project, and teachers have shared positive feedback.

Teachers also publish resources made with the tool on TES. This describes teacher-led use, not a partnership between Entrefio and TES.

Entrefio is the next chapter of Projeto Combinado. Weekly planning and daily organization already sit alongside activity creation, editing and a reusable library. Broader monthly and annual planning remains part of the longer-term vision.
