1. The pile of tests that goes home with the teacher
Every teacher knows this scene. Class ends, the school empties, but the work continues inside the backpack: a pile of tests awaiting correction. At home, when rest should begin, another journey begins. Count marks, check answer sheets, add notes, fill out spreadsheets, check summation errors.
The problem is not just time. That's the kind of time correction takes up. It invades the night, the Sunday, the interval between one obligation and another. It steals energy from those who need to get to class in one piece the next day.
And there is still the tension of small mistakes. A question corrected incorrectly becomes a conversation with the student. A wrong sum becomes rework. A changed version of the test becomes a headache for the teacher and the coordination team.
Corrigi was born to attack this specific point in the school routine: removing the mechanical burden of assessment without taking away the teacher's pedagogical control. Technology comes in where it should: to give back time, reduce errors and let the teacher focus on what really requires a human eye.
2. Creating a good test is also time-consuming
Before correcting, the teacher needs to construct the assessment. And that requires more than asking questions. A good test needs to have clear statements, well-thought-out alternatives, an appropriate level for the class and consistency with what was worked on in class.
In practice, this process usually happens in tools that were not designed for evaluation. The header moves out of place. The numbering breaks. The image doesn't fit. The correct alternative is marked in the wrong file. And, when the school asks for different versions to avoid cheating, the work multiplies.
There is also a critical organizational problem that begins long before application: the delivery time for printing. Schools do not like receiving the printed PDF at the last minute, as this breaks the secretariat's logistics. But as preparing, reviewing and diagramming everything is a lot of work, the teacher often finds himself under pressure, working late nights to avoid delaying delivery.
Corrigi organizes this process from the beginning. If the teacher prefers to create the test with his favorite LLM (such as ChatGPT), he can generate the questions there and use our mechanism to paste the ready-made test directly into the system. But it can also use our advanced native AI capabilities to create the proof from scratch with analysis, content review, and print prep in advance.
The idea is simple: a well-done assessment should not depend on a free night, patience with formatting and several copies of files spread across the desktop.
3. Corrigi in three steps
Corrigi is a platform for creating, printing and correcting multiple choice tests. Works on computer and cell phone, with app for iPhone and Android.
First, the teacher creates the test. You can assemble question by question, paste a ready-made text into a LLM of your choice (such as ChatGPT) or use our native AI to obtain structured suggestions with content analysis. Corrigi organizes statements, alternatives and templates in a format ready for review.
Then, the teacher generates the PDF. The file is designed for printing and may contain several versions of the same test, with shuffled questions and alternatives. Each sheet receives its own QR Code, which identifies the student and the version applied.
Finally, comes the correction. After application, the teacher opens the app, points the camera at the answer sheet and sees the result in seconds. No need to separate proof by version, no need to type notes, no need for a scanner.
It's a flow designed to fit into the real school routine: create, print, apply, point the camera and move on to the next sheet.
4. Artificial intelligence with the teacher in charge
Many teachers are wary of AI in assessment, and this caution makes sense. A proof cannot be treated as any text. A poorly formulated alternative, an ambiguous statement or a conceptually wrong answer affect students' learning and confidence.
Therefore, at Corrigi, AI does not replace the teacher. Whether the teacher brings ready-made questions from another model (like ChatGPT) or creates them using our in-house AI with advanced content analysis, it helps speed up the process. But the person who approves, edits, discards or adjusts is always the teacher.
Before a question enters the test, the teacher sees the statement, the alternatives and the correct answer. You can rewrite, change the correct alternative, adapt language, adjust difficulty or remove the entire question.
Corrigi also offers a test quality review. It helps to find common errors: a question without a correct answer, more than one possible answer, an alternative that is too obvious or a confusing statement. It's like getting a second look before printing.
The goal is not to turn AI into a teacher. It’s about using AI to get repetitive work out of the way and leave the teacher with more time for pedagogical judgment.
5. Different versions without duplicate work
Avoiding cheating usually creates more work for the teacher. Proof A, Proof B, separate templates, sheets that need to be checked carefully and the constant risk of correcting one version with the template of the other.
In Corrigi, the teacher creates the test once. When printing, choose how many versions you want to generate. The system automatically shuffles questions and alternatives, maintaining the correct answer sheet for each sheet.
The QR Code printed on top solves the most problematic part. It identifies the student and the version of the test. When correcting, the app reads the code and applies the correct template on its own.
This means that the teacher can take the entire stack as it came back from the room, without separating by version, and correct one sheet after another. Less manual organization. Less risk of error. More speed.
6. Correction via cell phone, made for real school
In-camera correction needs to work outside of the pretty demo. In a real school, the lighting changes, the paper crumples, the student marks weakly, erases it, uses a different pen or submits the test crookedly in the pile.
Corrigi was designed for this scenario. The sheet has markers in the corners that help the app recognize and straighten the image before reading. The teacher does not need to align perfectly. Point the camera, capture and follow.
When the marking is clear, the note appears within seconds. When there is doubt, such as two marked alternatives or a half-deleted answer, the app shows the enlarged image so the teacher can decide quickly.
The image is read on the cell phone itself. The proof photo does not need to be sent to the cloud to be corrected. This makes the process faster, preserves student privacy and helps in schools with unstable internet.
The practical result is what matters: a class that would take hours to correct can be registered in a few minutes.
7. Adapting the test without starting from scratch
Every class has students with different needs. Some need more direct language. Others benefit from shorter utterances. There are also foreign students, bilingual schools and contexts in which translating an assessment makes a difference.
The problem is that adapting the test manually usually turns into another whole job. The teacher needs to preserve the assessed content, simplify the text, review each question and ensure that the adapted version remains fair.
Corrigi helps in this process with test adaptation. The tool can simplify statements or translate the assessment into another language, maintaining the original pedagogical idea. The teacher reviews it before using it, as with any important part of the test.
This does not turn inclusion into a magic button. But it removes some of the operational burden that prevents a lot of good adaptation from happening on time.
When the tool saves time at this point, the teacher gains space to do what really matters: look at the student, understand the need and decide the best way to assess.
8. Notes that become a diagnosis
Corrigir quickly is important. But the greatest value comes later: understanding what the class learned and what needs to be revisited.
At the end of the correction, Corrigi organizes the results into reports. The teacher can see the class average, distribution of grades, success rate per question and points where many students had difficulty.
This type of information changes the next class. If a large part of the class got the same question wrong, the content may need to be repeated. If an alternative has attracted many students, it may reveal a common question. The test stops being just a conclusion and becomes a planning tool.
The results can also be exported to spreadsheets and systems used by the school. Corrigi does not try to replace the entire school routine. It fits into it and reduces the heaviest part.
9. The care behind simplicity
When a tool works well, it looks simple. But this simplicity depends on several choices made behind the scenes.
Corrigi uses the same correction core in iPhone, Android, and the web. This helps maintain consistency: the reading of the test does not change because the teacher uses another device.
Corrections take place on a cell phone whenever possible, to be quick and respect the student's privacy. The web platform was designed to load well in different places. Payments go through recognized providers, without storing card data in Corrigi.
Even the purchase of credits was designed so as not to interfere with the correction. If the teacher is in the middle of a pile of tests, the system should not interrupt the flow with bureaucracy at the worst moment.
These details do not appear at first glance. But they are the ones who make a difference when the tool stops being new and becomes part of the teacher's weekly routine.
10. The bottom line: giving time back to the teacher
Corrigi does not try to reinvent education. It does not say which methodology the teacher should use, nor does it replace the experience of those who know the class.
The proposal is more direct: reduce the time spent on mechanical assessment tasks. Create a test with less friction. Print different versions without rework. Corrigir on your cell phone in seconds. Transform notes into diagnosis. Do all this while keeping the teacher in charge.
For those who teach, few things are as valuable as quality time. Time to better prepare an explanation. Time to talk to a student. Time to rest without guilt. Time to return to the room with energy.
Corrigi is available in browser, iPhone and Android. It's free to get started, no credit card required to create an account. The teacher can test with a real class and feel, in practice, how much time goes into the week.
Create the proof. Print. Correct on your cell phone. Use whatever time you have left to teach better.
