About OtterFill

OtterFill is an AI form filler. Upload any form and it explains every question in your language, prefills answers from your documents and checks the form; you confirm each answer and export the filled original.

What OtterFill is

What it does
It turns a form into a short list of clear questions in your language and writes your answers into the original. It does not submit forms for you.
What it is not
OtterFill is a form-filling tool, not legal, tax or immigration advice. You check your answers and decide what to submit.

How our form guides are made

From the official source
Each guide is written from the issuer's own form and instructions, and from the law where a rule is stated. Every fee, deadline and number is checked against the issuer.
Dated and linked
Each guide names the edition it follows, shows the day it was last checked against the official form and links to the official source.
Checked again
We check each guide again every six months and whenever a new edition comes out. A guide we can no longer verify is taken down.
An explanation, not advice
A guide explains what a form asks. Forms change, so check the official instructions before you submit.
