About ImprovCoach

A pocket-sized scene partner. Built so you spend less time picking and more time playing.

Meet Lucas

Hi, I'm Lucas Vieira — also known as Lucas the Second. I'm a software engineer originally from São Paulo, living in the Netherlands since 2021. I take improv classes at Boom Chicago in Amsterdam, and I'm wildly passionate about this art form.

I built ImprovCoach because I want more people — especially students and beginners — to keep practicing, solo or with their group. The more reps, the more joy.

Find me as @iamlucasii

What you can do

• • Run a session for short-form, long-form, or solo practice.
• • Tap big buttons for locations, professions, relationships, objects, emotions and first lines.
• • Get a scene initiation: a first line, an opening image, or a coach's heightening note.
• • Run group warm-ups in 10, 20, or 45 minutes — guided, with built-in timers.
• • Use voice mode to ask for prompts hands-free while you record yourself.
• • Save the gold to revisit later. Stored on your device.

Voice mode tips

• • "Give me a location" / "object" / "profession" / "relationship" / "emotion" / "first line"
• • "Scene" — gets you a random scene initiation
• • "Another" — same category, fresh prompt
• • "Two minute timer" — starts a timer
• • "Stop" — turns off the mic

Voice mode uses your browser's built-in speech recognition. Best on Chrome (Android, desktop) and Safari (iOS, macOS).
