How it works

A classroom loop, not another dashboard.

Lingua Viva starts from a real teaching habit: notice something, record it quickly, and use it to prepare tomorrow's lesson.

01

Capture

Write or dictate a short observation during class. The note is saved locally and tagged to the student.

-
02

Lens

The student lens updates CEFR signals, RTI context, and observation history without replacing teacher judgment.

-
03

Prepare

Generate differentiated activity ideas that match the class, the unit, and the evidence teachers have recorded.

-
04

Reflect

Keep a private implementation note so the curriculum improves from actual classroom use.

For education

Built around the people using it.

T

Teachers

Capture observations, review student lenses, prepare tiered activities, and draft parent-safe notes from local evidence.

Strongest current tier
C

Coordinators

Programme overview is live. Evidence, capacity, and trends are deliberately deferred until pilot data exists.

No overclaiming
S

Students

Student-facing workflows are planned only after teacher adoption signals justify building them.

Teacher-first product boundary
Open source

Schools should be able to inspect the tool they trust.

Lingua Viva is designed as a local-first education tool. The privacy rules, support checks, and data paths are visible in code so a school can review them before a pilot.
