This Koro AI review is for students deciding whether a document-based study tool fits a real class. Start with the file you have and the task you need to do after studying. A polished feature list cannot answer either question.
Wizidoo publishes this comparison. It is based on official product descriptions reviewed on September 21, 2026, plus Wizidoo's current product. It is not a paid-account test or evidence that one app produces better grades.
What Koro AI says it can do
Koro AI's English site says it can turn PDFs, Word documents, and photos into study notes and personalized quizzes. It also advertises an AI coach. Calling it a passive summary tool would be inaccurate.
That said, an upload feature is not the decision by itself. Check the file format you actually have, the account limits, and how feedback works after a wrong answer. If your source is a Word file, Koro's stated support for that format may be material. Wizidoo accepts photos and PDFs, not Word files.
Before uploading, make sure you have permission to use the material with the service. Remove information about other students when it is not needed for studying.
Use one confusing point as the test
Choose a page that contains two ideas students commonly mix up. A science class might distinguish mass from weight, for example. In each product, check whether the question keeps that distinction and whether its explanation agrees with the class material.
Then close the app and answer a related question yourself. Repeating an explanation is different from using it. A representative page of your own notes, including a diagram or typical handwriting, is a better test than a perfect demo PDF.
Where Wizidoo takes a different approach
After a photo or PDF is imported, Wizidoo prepares a first quiz from that course. Students can work through quizzes, see a mastery percentage for the course, and revisit missed questions. The indicator reflects answers inside Wizidoo. It does not establish full coverage of a school curriculum or predict a grade.
Wizidoo does not offer an Anki-style schedule for future reviews or automatically combine several courses into a spaced-repetition plan. If scheduling is the reason you are changing tools, read our Anki alternative guide before deciding.
The web interface is available in English. The iPhone app also supports English, and there is no native Android app. Android users can use Wizidoo in a browser.
What a US family should verify
An English product page does not establish alignment with a US teacher's syllabus. Compare the generated material with the student's class notes, then confirm account eligibility, support language, payment currency, and renewal terms directly with the service.
Wizidoo's parent dashboard shows course difficulties and, when available, the explanation and advice shown to the child. That may help a parent choose one point to revisit together. It does not show every assignment in a school portal. Our parent dashboard guide explains how to keep that conversation useful.
We do not infer that Koro lacks a parent feature just because a page does not mention one.
Make a small decision first
Wizidoo offers the first 3 complete courses free for life. Premium is annual and charged immediately, with no trial period. See current pricing before paying. Check Koro's current offer directly instead of relying on a quoted price from an older review.
Try one course in Wizidoo, or use the same lesson within each service's limits. Choose the workflow whose questions and feedback you can check against the source. For more alternatives, see our AI study app guide.
Frequently asked questions
Can I upload a Word document directly into Wizidoo for studying?
No, Wizidoo only accepts photos and PDF files. If your notes are in Word format, convert them first or consider Koro AI, which advertises support for Word files.
Does a high mastery score in Wizidoo guarantee a good grade on a school exam?
No, the mastery percentage only reflects your answers inside the application. It does not measure complete syllabus coverage or replace practice with actual test formats.
Is the Wizidoo iPhone app available with an English user interface?
No, the iPhone application interface is currently available only in French. US students who want an English interface can access Wizidoo using any desktop or mobile web browser.
Does Wizidoo automatically schedule spaced-repetition reviews like Anki?
No, Wizidoo does not generate review schedules or automatically combine multiple courses into a spaced-repetition plan. You must manually choose which courses and past mistakes to revisit.
Is there a free trial for the Wizidoo Premium annual subscription?
No, Wizidoo Premium is billed immediately upon sign-up with no trial period. However, you can study up to 3 complete courses free for life before deciding to purchase a subscription.
Can Android users download a dedicated Wizidoo app?
No, there is no native Android app available. Android users can access all course features by signing in through a standard mobile web browser.
Does the Wizidoo parent dashboard connect to a school's portal to track homework?
No, the dashboard only shows course difficulties, explanations, and advice generated inside Wizidoo. It does not display school portal assignments or track classroom grades.
Does Koro AI provide a dedicated parent-monitoring account?
Official product pages reviewed do not mention a parent feature, though its absence cannot be confirmed. Check Koro AI's current account settings directly to see what monitoring tools exist.
What should I check before uploading my study guides or class notes to either AI tool?
Confirm you have permission to upload the study materials to a third-party service, and remove any personal information about other students before importing the file.
What is the best way to test whether Wizidoo or Koro AI works for my class?
Upload a short, challenging lesson with a subtle conceptual distinction to verify that the generated questions and feedback align with your notes. Then close the app and answer a related prompt on paper to confirm you understood the concept.
