For IB teachers
Turn 30 IB drafts into a clear teaching plan.
iBacalao helps IB teachers review student drafts, identify class-wide criterion gaps, and generate editable feedback aligned to IB expectations.
Designed for teacher judgment, not to replace it.

The problem
IB feedback takes hours. The next lesson still has to be planned.
Too many drafts
Hard to see patterns
Feedback consistency
~3 hrs
per IA draft
24+
drafts per class round
How it works
From individual drafts to class-level insight.
iBacalao reads student work against IB criteria, then gives teachers a review queue, editable comments, and a map of what the class needs next.
01
Students submit drafts
Invite students with a class code or upload drafts yourself.
02
iBacalao reviews against criteria
Each draft is analyzed with criterion-level strengths, weaknesses, and next steps.
03
Teachers decide what happens next
Edit feedback, flag students, export reports, or plan the next lesson.

Teacher control
AI drafts. Teachers decide.
Editable before students see it
Every comment is a draft. You review, revise, and approve before anything is shared.
Rubric language stays visible
Criterion descriptors are always shown alongside the feedback, so you stay grounded in IB standards.
No automatic accusations or final grades
Integrity signals prompt a closer look, not a verdict. Grades remain yours to assign.
