AI / SAAS sector | 2 months timeline | Web app designing | B2B & B2C
My role as a UI/UX designer involved cross-team collaborations, research & design.
Before I came in,
QuillBot existed with around 1M users, a WIP web app with just 2 features paraphraser & summariser. The payment flow, the dashboard’s peripheral area & payment flow were all under the ideation stage.
The problem is,
Non-native speakers of any language expect guidance. English, with wide usage, is a need in this era. Many non-native speakers struggle to write college essays & work emails. Also, they struggle to learn the language. So the process of writing is time-consuming & difficult for them.
Competitors were focused on just correcting the text, instead of educating the users, which also became our opportunity.
We followed simple 3 step analysis process
Attitudinal analysis
Interviews, Survey, Online Feedback
92% of users expressed satisfaction with QuillBot’s paraphrasing accuracy. However, 15% suggested the need for more clearer UI of tools for undisturbed writing. 78% of respondents found the summarization feature helpful for condensing lengthy texts, while 10% requested more options for customizing summary length.
