Assistant- What's the difference between Hauptwohnung and Nebenwohnung?
Your Hauptwohnung (main home) is where you mainly live. A Nebenwohnung (second home) is any other home you also use. If this is your only home in Germany, choose main home.

Questions and answers
What is OtterFill?
OtterFill is an AI form filler. Upload any form and AI turns it into clear questions, explains anything unclear, prefills answers from your documents and checks the form, so you're done in minutes. It works in 24 languages, and you download the original form filled in.
Can I fill in a German, French or English form if I don't speak the language?
Yes. Every question is shown in your language with the form's wording underneath. You can type your answers in your language and OtterFill writes them in the form's language, keeping your words so you can check them.
Which files can I upload?
PDF forms (fillable or flat), scanned pages, phone photos and screenshots, Word (.docx) and Excel (.xlsx) files, up to 10 MB.
How does OtterFill use AI?
AI reads the form and turns it into clear questions, translates it into your language, answers your questions about any field, prefills answers from documents you add, writes your answers in the form's language and checks the whole form before you submit.
Can the AI make mistakes?
Yes, like any AI it can. That's why answers it fills in wait for your confirmation, the form's own wording stays visible beside every question, and the check points out problems. Always read the form before you submit it.
Does OtterFill submit the form for me?
No. OtterFill gives you the filled form and a list of your answers. You check them and submit the form yourself, the way the office asks for it.
Is OtterFill legal or immigration advice?
No. OtterFill is a form-filling tool. It explains what questions mean, but it doesn't give legal or immigration advice. For advice about your case, talk to a qualified adviser.
Is it free?
Reading a form, seeing it in your language, filling it in and downloading a list of your answers are free, and you can try the AI assistant. Downloading the filled original and full AI help are paid per form.
What happens to my documents?
Forms, documents and conversations are deleted automatically after 7 days (30 days for a form you paid for), or right away when you delete them. Answers are never logged or used to train models.
