KnowBud
Read full descriptionHide full description
Your commute is the most wasted part of your day. KnowBud turns it into a 5-minute classroom. Pick a topic, tap start, and an AI tutor starts teaching you through a real, back-and-forth conversation — not a recording, not a quiz machine. It asks you questions, listens to your answers, and builds on them. Completely hands-free — pure voice, nothing to read or tap. TWO WAYS TO LEARN • Hands-free: pure voice, nothing to read or tap. • Guided: voice plus visual cards, live captions, and quick tap-to-answer questions — perfect for the train or the bus. Hands-free mode is voice-only by design, but no app replaces your attention on the road. Always follow local laws, and save guided mode for when you're not driving. LEARN ANYTHING Choose a ready-made journey — Business Fundamentals, Tech Founder Essentials, Finding Your Purpose — or type any topic you want and KnowBud builds you a full mini-course in minutes. Public speaking, wine, negotiation, crypto — if you can name it, you can learn it. That includes whatever life just handed you. Buying your first home, planning a wedding, becoming a manager, moving abroad — describe your situation and KnowBud writes the course for exactly that, then teaches it to you out loud. A BRIEFING MADE FOR YOU Start your commute with a 5-minute daily briefing curated to your interests. Hear the stories that matter, then ask KnowBud to go deeper on any of them — by voice. IT GETS SMARTER KnowBud remembers what you tell it and tailors future lessons and briefings to you. The more you learn, the more personal it gets. You're always in control of what it remembers. BUILT FOR REAL COMMUTES • 5-minute lessons that fit an actual commute • Quick setup — your first lessons are free, no payment details • Pick up exactly where you left off • Keep a daily streak going across every topic Your first 3 lessons are free — then try everything with a 7-day free trial.
