SB here, founder of Onepin. Our launch goes live on Saturday at 12:01 AM PT. I want to use this thread to learn how you work, not to pitch.
Here is what we keep seeing. A team generates 1,200 lines of AI voice for a product video, an ad campaign or a course. The voice sounds great. Someone listens to the first twenty lines, nods, and ships the rest on trust. Line 1,200 reads the product name from its spelling, and the customer is the first one to hear it.
We spent two years at Podonos measuring how AI voices sound, with 150,000 human listeners doing the rating. The voices got the delivery right. What kept failing was names, prices and dates, and the only check most teams had was one person with headphones.
So, honestly:
1. Do you listen to all of it, some of it, or none of it before it goes out?
2. What has slipped through? A brand name, a number, a date, your own company's name?
3. If a check existed that caught those before you published, what would it have to get right for you to trust it?
I'll answer every reply here, before and after launch day. If you want to hear what the check catches, onepin.ai runs one line without an account.

Hi everyone,

I studied computer science, but my career went into textiles, and I stayed there for 22 years. Code was always at the back of my mind.

When AI tools took off in 2025, I started building again, first just as a hobby. Now I have a few small apps in the pipeline. The first one, ClipQuery, went live this month: you ask a question about a YouTube video and it shows you the exact moment where it's answered. (ClipQuery's profile on Product Hunt | Product Hunt)

I'm Shun, the maker of Ownfeed.

We launched here today, and I want to use this thread to learn from you, not to pitch.
