Hello DuoCards Team, First, thank you for creating such a useful app for language learners. I have a suggestion that could make DuoCards even more powerful: adding an API (Application Programming Interface) feature. An API would allow users to connect DuoCards with other tools and automate adding words, for example: Syncing vocabulary directly from Google Sheets or Excel. Creating Zaps or integrations with Zapier/IFTTT to import words automatically. Allowing teachers or learners to upload word lists programmatically instead of manual entry. This feature would save users a lot of time, especially those who study with larger vocab lists, and it would also open DuoCards to integrations with many popular platforms. I believe an API would be a valuable addition and highly appreciated by users who want more flexibility and automation. Thank you for considering this idea! Best regards,
