As answered by people managing Langfuse and Structifys.app.
Structifys.app's answer:
Structifys is currently an early stage platform primarily used by IB students and independent learners.
IB Diploma Programme students
Independent IB tutors and mentors
IB focused tutoring platforms
International schools offering the IB curriculum
Structifys.app's answer:
Structifys focuses on AI powered academic scaffolding rather than AI generated assignments. Instead of writing Internal Assessments for students, it guides them through research questions, structure, modelling approaches, and clarity improvements while preserving academic integrity.
Structifys.app's answer:
Most tools either provide generic templates or generate full assignments using AI. Structifys takes a different approach by helping students think through their investigations step by step. It offers structured guidance, subject specific IA workflows, and integrity focused feedback designed specifically for IB Internal Assessments.
Structifys.app's answer:
The primary audience is International Baccalaureate students working on Internal Assessments across subjects, particularly in mathematics and analytical subjects. It is also useful for IB mentors, tutors, and educators who support students through the IA process.
Structifys.app's answer:
Structifys was created to address a common challenge faced by IB students. Many struggle to structure their Internal Assessments and often rely on generic templates or AI tools that generate full essays. The idea behind Structifys was to build a platform that strengthens students' thinking and structure while maintaining ownership of their work.
Structifys.app's answer:
Structifys is built using modern web technologies and AI infrastructure including AI language models for academic recommendations, cloud hosted backend services, and scalable web frameworks for delivering interactive IA workflows.
