Yes, your tool is a smart way to fill a real gap in independent Dutch learning. By automating the creation of practice scenarios from your own learned words, you address a common problem: passive input without active recall. The key is whether it helps you produce language consistently and accurately, not just generate exercises.

Your approach of writing mini-situations and daily journals is grounded in solid language-learning research. Active production, especially in meaningful contexts, strengthens memory far more than passive review. Automating this with AI can save time and reduce friction, which is a genuine advantage. However, the quality depends heavily on how well the AI understands your current level. If it generates sentences with grammar or vocabulary you haven't studied, it may introduce errors or overwhelm you. A tool like this works best when you can easily flag or skip exercises that feel off.

A practical next step is to test the tool with a small set of 20-30 words and phrases you know well. Use it for a week, then check if you can recall and use those items in spontaneous conversation or writing. Also, compare your progress with a simple control: just writing those same items manually in a journal. This will show you if the automation truly boosts retention or just feels more efficient.

Be honest about tradeoffs. AI-generated scenarios can sometimes feel generic or miss cultural nuances. For example, ordering a coffee in the Netherlands often involves specific phrases like 'een koffie verkeerd' or 'een latte macchiato' that a general AI might not know. You can improve this by feeding the tool examples from real Dutch media or conversations you encounter. Also, consider adding a spaced repetition feature that revisits older words at increasing intervals, which is proven to cement long-term memory.

Finally, share your tool with other learners for feedback on usability and accuracy. They might spot errors or suggest features you missed. Keep it simple and focused on your core need: active practice that matches your current knowledge. Avoid adding too many bells and whistles early on, as that can distract from the main goal of building fluency through consistent, meaningful use of Dutch.
