See blablabla in 2 minutes
April 14, 2026 · 2 min read
If you've ever read both parts of a scene out loud in your kitchen at midnight, this one's for you.
blablabla is a rehearsal partner app for actors. You import the script, cast a voice to each character, and rehearse alone - the app reads every other character's lines and waits, patiently, for yours.
Transcript
The full 2-minute walkthrough, in prose. Skim for the parts you care about.
0:00 - The sides arrive
Your agent just sent the sides. Two characters. Audition's tomorrow morning. You're supposed to walk in knowing it cold.
0:11 - Rehearsing alone doesn't work
So you do what you've always done. You read both parts. You record yourself and play it back. You text a friend. But you've asked her twice this week, and the script's under NDA anyway.
0:26 - blablabla
This is blablabla. It's a rehearsal partner. One job. It speaks everyone else's lines. Then it waits, patiently, for yours.
0:38 - Import the script
You drop in the PDF. Or the docx. Or a photo of the printed sides. It reads the script, finds the characters, and tags every line.
0:50 - Cast the voices
You tell it which role is yours. The others get their own voice. Sam is calm, British. Riley is warm, American.
1:01 - Rehearse (the Wrong Bag scene)
SAM. That's my bag.
RILEY. It's really not.
SAM. Black duffel. Broken zipper on the side pocket.
RILEY. You just described every bag at every gym in this city.
SAM. I set it down right here. I went to get a coffee.
No coaching. No extra words. No one cuts you off.
1:18 - Four modes + accuracy
Three ways to run it. Listen. Practice, where a dial sets how much of your own line you see -- all of it, the first few words, the first letter of every word, or none of it -- and moves whenever you like. Or Selftape. When you're done, you can see exactly where you dropped a line.
1:37 - Enough blablabla
Your scene partner doesn't cancel. Doesn't judge. Doesn't talk over you. Enough blablabla. Go rehearse.
