WorkbookPDF builds custom language workbooks: pick a language, a topic and a CEFR level from A1 to C2, and it produces a printable PDF with fill-in-the-blanks, multiple choice, true/false, translation and word matching exercises, illustrated, with the answer key included, across 23 languages.
Printable and offline is the point, not a limitation. Language learners who study on paper are doing so deliberately, often because a screen is where the distractions live, and almost every tool in this category assumes an app. Two to four hours of content per workbook with answers included makes it usable by a tutor as well as a learner.
Marc Lou sells it as one-time passes rather than a subscription: $19 for seven days, $29 for thirty, $99 for 180, each with unlimited workbook creation during the window, plus $9 per workbook for commercial rights. Time-boxed passes suit bursts and penalise steady use, generated exercises need checking by anyone teaching from them, and quality across 23 languages will not be even.
