A mobile English training app for non-native Product Designers who already work in English — and want their words to reflect the depth of their thinking.
Join early accessOpen Tella before a critique, a PM sync, or a stakeholder review. Speak once, sharpen your thinking, then try again.
Explain why you changed the onboarding flow — and make a clear recommendation.
“I changed this because I think the previous flow was a little confusing…”
You can defend a design decision, surface a trade-off, and turn research into direction. But in English, all that thinking can collapse into:
“I think this is better because it’s simpler.”
Tella helps you close the gap between what you know and what you can express.
PM · “Can we simplify this to one step?”
Design critique, PM discussions, user interviews, and stakeholder presentations — not airport check-ins.

Design language
Nuance
Understand gaps in vocabulary, structure, reasoning, nuance and the language Product Designers actually use.
Try the same moment one more time and hear yourself express more of the professional you already are.
No small talk lessons. Practice the situations where your ideas, influence and craft are judged.
Vocabulary and grammar for everyday situations.
Generate polished language you can copy and paste.
Train the language and reasoning behind your design work.
