  We propose a PiggyBack, a Visual Question Answering platform that allows
users to apply the state-of-the-art visual-language pretrained models easily.
The PiggyBack supports the full stack of visual question answering tasks,
specifically data processing, model fine-tuning, and result visualisation. We
integrate visual-language models, pretrained by HuggingFace, an open-source API
platform of deep learning technologies; however, it cannot be runnable without
programming skills or deep learning understanding. Hence, our PiggyBack
supports an easy-to-use browser-based user interface with several deep learning
visual language pretrained models for general users and domain experts. The
PiggyBack includes the following benefits: Free availability under the MIT
License, Portability due to web-based and thus runs on almost any platform, A
comprehensive data creation and processing technique, and ease of use on deep
learning-based visual language pretrained models. The demo video is available
on YouTube and can be found at https://youtu.be/iz44RZ1lF4s.
