I built an AI tool that automatically adds stylised captions to videos — looking for feedback from creators

Hey everyone, I’ve been working on a small project called AI Video Captioner. It’s a web tool that automatically generates and syncs captions for short-form videos like Reels, TikToks, and YouTube Shorts.

I made this because I noticed many creators spend a lot of time adding captions manually, and most existing tools felt either slow or complicated. With this one, you just upload a video, and it:

• Transcribes speech automatically

• Syncs the captions to match the audio

• Lets you style or format captions before exporting

It’s built using Bubble with some AI integrations.

I’d really appreciate your thoughts on a few things:

What do you currently use for adding captions or subtitles?

What’s most frustrating about your current workflow?

Would a simple browser-based tool like this fit into your process?

If you’d like to see how it works, you can check it here: https://app.aivideocaptioner.com

I’m mostly looking for honest feedback from creators — what works, what doesn’t, and what would make it better.

Thanks in advance for taking a look!
