upload_password_protected_file

Problem: I can't upload my file / upload is failing / loading forever

Solution: Hi,

Sorry to hear the upload isn't working. In most cases this happens when the file you're trying to upload is password-protected. Please try the following:

Open the file on your computer and remove any password or editing restrictions.

Save the unprotected version, then return to Studyflash and click "New Deck" to upload it again.

Password-protected files can't be processed by our generator, so removing the protection should resolve the issue.

Let me know if this helps or if you still run into problems!

upload_cant_login_laptop

Problem: I can't log in on my laptop to upload documents

Solution: Hi,

Sorry you're having trouble signing in on your laptop - I know that's frustrating when you just want to upload a new document.

Please try the following steps, which usually resolve sign-in errors on the website:

Open an incognito/private browsing window (Chrome: Ctrl + Shift + N, Safari: Cmd + Shift + N, Edge/Firefox: Ctrl/Cmd + Shift + P) and sign in there first.

If that works, clear your regular browser's cache and cookies, then try again in a normal tab.

These steps refresh any stored login data that might be blocking access.

Let me know if this gets you back in, or if anything else pops up!

upload_ai_cant_read_document

Problem: AI can't read my uploaded documents

Solution: Hi,

I'd love to help you get your documents working! To identify the right fix, could you let me know:

Are you receiving an error message when you try to create a new deck, or does the loading simply never finish?

Is the file you're uploading password-protected or secured in any way?

Your answers will help me provide the most accurate solution.

upload_file_not_recognized

Problem: The app doesn't recognize my file was uploaded

Solution: Hi,

I understand that it's annoying when Studyflash doesn't recognize that your file has already been uploaded after uploading.

Please simply upload the document again and restart generation. In most cases, re-uploading fixes the problem immediately.

This occasionally happens when the internet connection was briefly interrupted during the first upload.

Let me know if that worked or if you have any other questions!

Note: German: "Er erkennt nicht dass die Datei bereits hochgeladen ist"

upload_free_plan_limit

Problem: I can't upload more files - I can only create a deck / button not visible

Solution: Hi,

I understand it's confusing when the "Create" button is no longer visible. On the free plan, you can generate only one AI-powered deck; after that, the option to upload additional files or start new creations is disabled.

Here's what you can do:

If you want to keep using the free plan, delete your existing deck (three-dot menu next to the deck title -> "Delete"). This will free up your single deck slot so you can upload a new file and generate a fresh deck.

If you'd like unlimited deck creation, upgrade to a paid subscription in Account -> Settings -> Subscription. Feel free to use the promo code COMMUNITY20 for 20% off your first month.

This limitation is in place to give everyone a chance to try Studyflash while keeping our server costs manageable.

Let me know if this resolves the issue or if you need any clarification!

upload_delete_document

Problem: How do I delete an uploaded document?

Solution: Hi,

I understand you'd like to remove a document you previously uploaded.

Individual PDFs can't be deleted once a deck has been created. To remove the document, please delete the entire deck and then upload the correct file:

Go to your deck list.

Click the three-dot menu next to the deck's title.

Select "Delete."

After deleting, you can create a new deck with the correct document.

Let me know if you need any more help!

Note: German: "Wie kann ich eine Datei loschen?". Also asked as: ik wil een geupload document opnieuw verwijderen; verwijderen van bestanden; het verwijderen van documenten is niet meer mogelijk

upload_printing_pdf_not_working

Problem: I can't print/export my summary as PDF

Solution: Hi,

Thanks for your message. Currently printing is only supported in the webapp under https://app.studyflash.ai

Note: German: "Ich mochte meine Zusammenfassung ausdrucken aber es funktioniert nicht". Also asked as: comment peut avoir les resumes en pdf pour imprimer; pdf export gestartet - bitte vervollstandigen

upload_max_chat_material

Problem: Max says I need to upload material but I can't find where to do it

Solution: Hi,

Could you please elaborate on the issue you're facing?

upload_multiple_files

Problem: Can I upload more than one file for flashcards? How do I upload multiple files?

Solution: Hi,

That is sadly not yet fully possible. You would need to first combine the files.

Note: German: "Kann ich mehr als eine Datei hochladen fur die Karteikarten?". Also asked as: Max vraagt om studiemateriaal te uploaden maar kan maar telkens een bestand invoegen; ich habe mehrere dateien die zu einem thema gehoren

upload_goodnotes_import

Problem: How do I import files from GoodNotes?

Solution: Hi,

Just export as PDF and then import.

Note: German: "Wie kann ich meine Dateien von Goodnotes hier einfugen?"

upload_documents_disappeared

Problem: My uploaded documents have disappeared / can't find my files

Solution: Hi,

I understand how annoying it is when your uploaded documents are no longer findable.

Please proceed as follows:

Restart the Studyflash app and open your library and look for it there, if this doesn't help, proceed as follows:

Tap "New Deck" and upload the document again.

Wait briefly until generation is complete - the deck should then appear in your library.

Sometimes the first upload gets stuck due to high load, so the deck isn't created. Re-uploading solves the problem in most cases.

Let me know if that works or if you have any questions!

Note: German: "Meine Dokumente sind verschwunden". Also asked as: tout mes documents ont disparu; meine ganzen kurse sind weg

upload_file_size_limit

Problem: What is the maximum file size I can upload?

Solution: Hi,

There is no maximum size, but smaller documents are strongly recommended.

Note: German: "Wie gross durfen Dateien sein?"

upload_max_cant_access_document

Problem: Max can't answer questions from my document - says he can't access it

Solution: Hi,

That's annoying - when Max says he "can't access this document," it's usually due to the upload or the file itself.

Try this (on web/desktop):

Re-upload the document

If generation/content gets "stuck" or doesn't come through properly, a re-upload often helps.

Check if your file is password-protected

If creating your deck fails or the document isn't processed correctly: check if your PDF has a password.

Remove the password protection and then try uploading again.

upload_repeatedly_required

Problem: I have to re-upload files every time to generate new materials

Solution: Hi,

Thank you for letting us know, we understand your frustration, this really shouldn't be happening and doesn't seem to be a common issue.

Generally, I would recommend it that you create all the materials right away after uploading the file.

upload_handler_not_found

Problem: Can't find handler for document - questions won't show

Solution: Hi,

Sorry you're running into that - if your document shows an error like "Can't find handler for document" and you're not seeing any questions, it usually means the generation didn't complete properly.

Please re-upload the document and try generating the questions again.

If you're trying to create a new deck and it fails, also check whether your file is password-protected. If it is, remove the password protection and then try the upload again.

If it still won't show the questions after re-uploading, tell me:

Are you seeing the issue during upload, or after the deck is created (when it's loading/generating)?

upload_max_not_reading

Problem: Max doesn't read my documents / can't extract information

Solution: Hi!

That's very weird. Could you please try again?

upload_cant_add_document_to_existing_deck

Problem: I can't add a document to an existing deck after creating it

Solution: Hi,

Thanks for the feedback, it's indeed not possible to add additional files to a deck afterwards. You can put the document in the course, though.

Note: German: "Man kann nicht nachtraglich noch ein Dokument in ein Deck importieren"

upload_long_time_200_pages

Problem: How long does it take to create flashcards from a 200-page document?

Solution: Hi,

I understand you want to know how long it takes to create your flashcard set. For a PDF with around 200 pages, generation can take several minutes. Due to increased traffic, there are currently occasional longer wait times.

Please give the process a few minutes. If creation isn't complete after about 10 minutes, wait a bit longer and then restart the upload. Our team is continuously working to improve speed.

Let me know if that helps or if any questions come up!

Note: German: "Wie lange dauert es durchschnittlich bis ein Karteikarten-Set erstellt wird bei 200 Seiten?"

upload_breaks_after_step_3

Problem: Upload breaks after step 3 / can't generate summaries or flashcards

Solution: Hi,

I'm sorry that the PDF upload on your smartphone breaks after step 3 and you can't create summaries or flashcards.

Please try to reupload your document, usually this should fix the irror. If this doesn't help, please let us know.

Let me know if that worked or if you have any other questions!

Note: German: "Upload bricht nach Schritt 3 ab - kann keine Zusammenfassungen oder Karteikarten erstellen"

upload_traffic_delays

Problem: File upload is taking very long / slow upload

Solution: Hi,

Sorry that your file upload is taking so long - I know that can be frustrating when you're eager to start studying.

Right now we're experiencing higher than usual traffic, which can cause uploads and AI generation to take a bit longer. Please wait a few minutes and then try the upload again; things usually speed up once the queue clears.

Let me know if this resolves the issue or if you need any clarification!

Note: German: "Das Hochladen der Datei dauert sehr lange". Also asked as: uploading file is taking very long; datei hochladen dauert ewig und bricht ab

upload_chat_incorrect_answers

Problem: Chat (Max) gives totally wrong answers about my uploaded document

Solution: Hi,

I'm very sorry to hear. Could you please elaborate?

Solution: Hi,

Why would you like to upload your files to Anki?

Note: German: "Kann ich alle meine Karteikarten als PDF exportieren damit ich sie in Anki hochladen kann?"

upload_need_separate_decks_for_files

Problem: How do I upload multiple files that belong to one topic?

Solution: Hi,

You need to create separate decks for them.

Note: German: "Ich habe mehrere Dateien die zu einem Thema gehoren - wie soll ich die hochladen?"

upload_file_not_loading_in_deck

Problem: I uploaded a file but it's not loading in the deck / nothing happens

Solution: Hi,

I understand that the upload is stuck and no content is being generated.

Please proceed as follows:

End the current upload (e.g., via the "X" or by going back a page).

Then upload the same file again.

If the upload still doesn't start after trying again, please contact us again so we can investigate more closely.

Note: German: "Ich habe eine Datei hochgeladen aber sie ladt nicht im Deck". Also asked as: hochladen einer datei wenn ich eine datei hochladen will kommt nur das und es passiert nichts; datei hochladen wenn ich meine datei in den ordner einfugen will wird es nicht geladen

upload_find_uploaded_courses

Problem: Where do I find my uploaded PDF courses?

Solution: Hi,

Click on library.

upload_flashcard_generation_stuck

Problem: I upload a file but AI doesn't generate flashcards - just recognizes the file

Solution: Hi,

Sorry you're running into this! When a file is recognized but the flashcards don't appear, the generation process has usually stalled for that upload.

Here's the quickest fix:

Close or delete the deck that's stuck.

Re-upload the same document and start the generation again.

Re-uploading almost always restarts the AI and completes your flashcards successfully. If it still doesn't work after a fresh upload, just let me know and we'll dig in further!

upload_delete_flashcard_deck_mobile

Problem: I have a flashcard file on my homepage that I can't delete

Solution: Hi,

I understand you'd like to remove the flashcard file on your homepage.

Here's how to delete a deck in the mobile app:

Open the homepage (deck overview) of the Studyflash app.

Swipe the relevant deck to the left.

Tap "Delete."

Confirm the prompt to permanently remove the deck.

Swiping left displays the context menu - without folders, this is the fastest way to delete individual decks.

Let me know if anything is still unclear!

Note: German: "Auf meiner Startseite ist eine Karteidatei die ich nicht loschen kann"

upload_wrong_language_translation

Problem: I uploaded an English PDF but it was translated into German

Solution: Hi,

Sorry about the mix-up! Once a deck is generated its language can't be changed, so the quickest fix is to create a new deck in English.

Here's what to do on your phone:

Swipe left on the German deck and tap "Delete" (this removes the incorrect version).

Tap "New Deck" and re-upload your PDF.

When the language option appears, choose "English" and start generation.

The language is locked in during generation, so re-uploading with English selected is the only way to switch it.

Let me know if that sorts it out or if you need any extra help!

upload_one_pdf_per_day_question

Problem: Can I only upload one PDF per day?

Solution: Hi,

I understand that can be a bit confusing. In the free plan of Studyflash, you can actually only create one AI-generated deck - regardless of whether you create it via the app or on the computer. This isn't limited to one calendar day, but to one deck total in the Free Plan.

If you want to upload more PDFs and create additional decks, you can switch to a paid subscription at any time. Here's how:

Open the Studyflash app and tap Account at the bottom right.

Select Subscription and choose the right plan for you.

For your first month, feel free to use the voucher code COMMUNITY20 - you'll save 20% on the first payment.

The switch only takes a few seconds, then you can immediately upload unlimited PDFs and create decks.

Let me know if that answers your question or if you need any more help!

Note: German: "Kann ich nur eine PDF am Tag hochladen?"

upload_second_document_in_folder

Problem: I don't know how to create a second document in a folder

Solution: Hi,

I understand you're trying to add a second document (deck) to a folder. On the Free plan, each workspace is limited to one AI-generated deck. That's why the option to create another deck isn't appearing.

If you'd like to add more decks, simply upgrade to a paid subscription:

Go to Account -> Settings -> Subscription on studyflash.ch

Select your preferred plan and complete the checkout

Enter the code COMMUNITY20 for 20% off your first month

Once you've upgraded, the "New Deck" button will be available again and you can create as many documents as your plan allows.

Let me know if this helps or if you have any other questions!

upload_problem_cant_add_after_upgrade

Problem: I upgraded but still can't create flashcards / upload stuck

Solution: Hi,

Sorry to hear the upload isn't letting you generate new flashcards anymore - I know that can be frustrating!

Please try the following steps:

Delete or close the current upload attempt.

Upload the document again from scratch.

Wait until the upload bar reaches 100% and the "Generate Flashcards/Quiz" buttons become active.

In most cases a fresh upload resolves the issue when generation gets stuck. If the problem continues after re-uploading, just reply here and we'll investigate further.

Let me know if this gets you back to creating flashcards!

cant_create_decks_or_upload

Problem: I can't create decks or upload files even though I paid

Solution: Hi,

Sometimes deck creation gets stuck during upload.

Please try re-uploading the file. In most cases, a fresh upload resolves the issue.

If the problem persists after re-uploading, please let me know and we'll investigate further.
