Every product seems to have an assistant now. In 2017, Coursera asked a question that sounds very current: what if learners felt like they had a mentor, not just a course catalog?

Tips that helped, and tips that didn't

Online courses can be lonely. Learners sign up full of plans, hit a hard week, and quietly disappear. Coursera already had an in-product tip system the product team called ALICE, and the research on it was clear. Tips that helped learners do something worked: 81% rated "rewatch this lecture" tips helpful, and 79% liked a heads-up about a hard assignment. Pep talks with no next step didn't: only 54%.

What the research showed.

Inspiration: brand mentors and mascots from other companies.

Finding the voice

My copywriting partner and I tested three personalities: an efficient Assistant, a reliable, future-focused Mentor, and an empathetic, casual Classmate. The Mentor won. It was helpful and honest, and always pointed to the next step. It was also short: under 100 characters, shorter than a tweet. We also set one rule: the mentor helps; it never sells. Surveys and upsells would live somewhere else, so learners could trust it.

Step two: rules.

From shapes to a face

I started by designing the moments where a mentor could show up: goal-setting, weekly progress emails, nudges when someone drifts, a chat window, and a celebration at the end. I built the first icons from Coursera's brand shapes.

An early, more literal take.

The mentor had to sit on top of everything, from video to quizzes to reading, so I gave it a three-tone gradient that would always stand out. Then I mapped every kind of message it might send: tips, help, chat, reminders, errors, and encouragement. Shapes alone got hard to read. Fully personified faces worked best. They carried the emotion of each message, and together they felt like a peer helping you through.

Icons for each kind of message.

Meet Dot

My final recommendation was a soft white face in a gradient ring, with a range of expressions from proud to sleepy to unimpressed. I suggested the name Dot. It showed up in short, useful tips: "Psst! Be ready to go over this material a few times." "Don't panic! You can retake this quiz." "Time to celebrate!"

What happened next

Dot never shipped; product priorities moved on. But in 2023, Coursera launched Coursera Coach, an AI learning assistant that grew out of the same idea. Looking back, the lesson I'd carry into any assistant today is the one the research taught us: a personality needs a job. Character only works when it's useful.
