Quick answer

Studaing wins for studying with official exam-style papers, rubric-based correction and planning; ChatGPT wins for instant open-ended doubts. They don't compete — they complement each other. Use Studaing to generate/practise/correct/plan (5 materials/day Free, 8.99€/month EU Premium) and ChatGPT to unblock doubts from the feedback ("I don't understand why I failed criterion 2, explain it with another example").

Introduction: two AIs, two jobs

Comparing Studaing vs ChatGPT as "which is better" is like comparing a driving school with Google Maps. ChatGPT is a general-purpose conversational AI that answers anything fluently. Studaing is a vertical educational AI that generates, saves, corrects and plans like your teacher would.

We used both for 2 weeks to prepare the same subjects (Physics Bach Year 2, History Bach Year 2, Maths ESO Year 4) with the same syllabus. Here is what one does and the other doesn't, with a table and a workflow to combine them without wasting time.

7-criteria comparison (2026)

| Criterion | Studaing | ChatGPT (Free/Plus) | |---|---|---| | Generate exam-style EVAU/IB papers by level | Yes: by topic, level, language, difficulty, 5-50 per generation, exam-style PDF | Not by default; generic manual prompt, variable quality, no official PDF | | Correction with rubric and strictness level | Yes: low/medium/high/strict, evaluates exclusively according to your rubric, feedback per criterion | No; generic feedback, not by criterion, doesn't mention your rubric | | Tutor with history by subject + photo/YouTube | Yes: 5 msgs/conversation Free, unlimited Premium, upload photo of problem | Yes, conversational, with limited memory | | Day-by-day planner + calendar + Pomodoro sessions | Yes: study-plan → calendar → guided study-sessions | No | | Teacher management (groups/tasks/bulk correction) | Yes: groupSubjects + assignments + group analytics | No | | Price | **Useful Free + 8.99€/month EU / $3.99 LATAM** | Free / Plus$ 20/month | | Hallucination risk in exams | Low (content bounded by level/rubric) | Medium (may invent data if prompt is vague) |

When to use each one (verdict by profile)

Choose Studaing as your base if:

Your exam is MCQ + essay + problems (EVAU/IB) and you need to practise with the real format.
You want feedback that raises your grade ("you missed mentioning CO₂, criterion 2") not just "looks good".
You need a plan and calendar that adapts if you skip a day.

Choose ChatGPT as a complement if:

You get stuck with Studaing's feedback: "I don't understand why the tutor says my argument is weak, explain it like I'm 14 and give me 2 more examples".
You want everyday analogies, brainstorming or rewriting your essay in another tone.

Choose both combined (workflow recommended by teachers):

Generate and practise in Studaing (https://studaing.com/en/material-generator): EVAU-style exam with your syllabus PDF.
Correct in Studaing (https://studaing.com/en/correction) with your rubric: receive grade + feedback per criterion.
Unblock with ChatGPT: copy the feedback you don't understand and ask "explain it with another example and 2 similar exercises to practise".
Go back to Studaing and generate those 2 similar exercises to consolidate.

This workflow is the one that reports an improvement from 5 to 7 in Physics in 2 weeks (see https://studaing.com/en/for-teachers).

Concrete example observed: a Bach Year 2 student generates 10 Hard dynamics problems, corrects 3 with a photo and receives "you forgot to decompose forces into axes". They paste that feedback into ChatGPT and ask "explain the decomposition with a 30° incline and two new examples". They return to Studaing, generate 2 similar problems and get them right. The full loop takes 18 minutes and fixes the procedure better than 1 hour of passive video.

FAQ

Can ChatGPT generate EVAU-style exams? It can, but without a rubric or official PDF, and quality depends on the prompt. Studaing does it by level/rubric and exports an exam PDF with no prompt engineering.

Can I use both for free? Yes: Studaing Free 5 materials/day + ChatGPT Free. For advanced correction and unlimited tutor you need Studaing Premium at 8.99€/month.

Which is more reliable for grades? Studaing, because it evaluates according to your rubric, not general knowledge. ChatGPT may hallucinate if your question is ambiguous.

Verdict

Don't choose one or the other: use Studaing as your academy and ChatGPT as your private tutor to unblock. If you can only choose one app to pass EVAU/IB, choose Studaing. Start free: https://studaing.com/en/landing.
