Make study cards from your PDF or text

Select a passage, write a question and answer, then take the cards to Anki. Each card keeps its source title, PDF page and excerpt. Free, with no registration.

1. Open your source

A text-based PDF, TXT or Markdown file: up to 10 MiB, 100 PDF pages and 500,000 characters. Reading happens here in your browser. Scans, OCR and password-protected PDFs are not supported.

Or paste your text

Your source and cards stay in page memory. They are not saved to your account or browser storage and disappear after closing or refreshing. Download the Anki TSV or a JSON project backup before leaving. This is manual card preparation, without model-generated questions.

How to prepare cards from a PDF

  1. Open a text-based PDF, TXT or Markdown file, or paste your material. Inspect the extracted text and source page.
  2. Select an exact excerpt. Write your own question and answer: the excerpt match is checked, while you review the answer’s meaning.
  3. Review the cards on this page. Download the TSV containing three fields: Front, Back and Source.
  4. In Anki, create a note type with these fields, add Source to the back template and inspect the import preview.

Set up the three fields in Anki

Create a separate note type named DCA Finance Source Cards with Front, Back and Source fields, in that order. Use Front on the front template and show Back and Source on the back. Enable HTML fields and check field mapping during import; the file includes the corresponding TSV directives.

Front template:

{{Front}}

Back template:

{{FrontSide}}<hr id="answer">{{Back}}<hr>{{Source}}

Questions about sources and cards

How can I continue on another device?

Download a JSON project backup, transfer the file yourself and choose Restore JSON project here. Review the preview and confirm opening it. The backup includes all extracted text, including pages without cards, and saved cards; the original PDF and unsaved draft are excluded. This is not cloud sync.

What is this tool for?

Turn material you have read into questions for self-review while keeping each answer linked to a source passage. Use a financial plan, fee explanation, calculation method or another study text you are allowed to use.

Does it generate questions from the PDF?

No. You select an excerpt and write the question and answer. The tool checks that the excerpt matches the chosen page and prepares the file. It does not automatically check the answer’s meaning or generate questions.

Where is my document uploaded?

File contents are processed in your browser and are not sent to an account, parsing server or external model. On the first PDF read, your browser downloads the reader component from this site. There is no automatic saving. Download a JSON project backup and explicitly restore it to continue later.

Can it read a scan or protected PDF?

The PDF needs an accessible text layer. OCR and password entry are not supported. For an image-only scan, recognize its text elsewhere and paste that text here.

How is TSV different from an APKG deck?

TSV contains three text fields and needs a note type to be configured on import. It is not a ready-made deck or a review schedule. Eight prepared, checked DCA tasks are available separately as APKG on the plan-template page.

What happens on repeated import?

Anki matches ordinary text notes using the first field and your import settings. Matching questions may update existing notes. Source filenames and pages do not make matching questions distinct. This file has no GUID and does not guarantee scheduling preservation: check the settings and import preview.

Practice with checked DCA examples

If you do not have material ready, start with eight tasks on fees, planned and recorded cash, average cost and a partial sale. Their numerical answers use the tool’s current calculation methods. Then inspect your own cash plan in the dashboard.
