Speak Better. Learn New Words
Free · In‑App Purchases
Stop overthinking your texts. Lexicon is a texting coach that helps you know what to say, a few minutes a day. Plus a new English word every day and guided English pathways.
Learn to reply better in short, game-like lessons. Pick the best reply, fix awkward drafts and play through real chats, then see exactly how your message lands.
Whether you're keeping a chat alive, asking someone out or messaging your manager, Lexicon helps you find the right words and say them naturally.

• Live conversations: each unit ends with a branching chat where your choices change the vibe and the ending
