Stop struggling with complex AI prompts. Let our AI convert for you.

👋 Hello! Hyojin here, Founder & CEO at Jinny Labs.

At Jinny Labs, we believe great ideas should never be hidden by a lack of writing skills. We are on a mission to help marketing agencies, creators, and business owners focus on their original ideas rather than repetitive drafting.

To make this happen, we built Jinny AI—a prompt-free AI marketing tool that generates high-converting, viral-ready copy in just 10 to 30 seconds. Beyond simple generation, our tool features a built-in "Writing Score Checker" to validate viral potential, ensuring your content actually converts.

I am launching this Thursday, so stay tuned!

Wow, this sounds super useful! The idea of a prompt‑free copy generator that also scores virality is impressive. Good luck with the launch on Thursday! If you're up for it, I'm launching on PH soon — would appreciate a follow (See PRODUCT HUNT LAUNCH Link in my profile). I'm working on The Sponge, an AI‑powered flashcard app that turns any webpage into study material.

Hi again!

Yes, it’s an AI copywriting tool designed to help users generate copy and content quickly without having to write complex prompts.

The virality score checker is a feature I personally developed through over a year of experimenting and researching on social media.

(If you sign up later, you should definitely try entering one of your posts to check the score!

I can add some free credits to your account.)

Also, as I mentioned in my previous comment, I checked out The Sponge website.

I think the logo is really cute! Wishing you a successful launch.
