Social Media content reposting automation tool

I have coded a tool that'll repost video from Tiktok to Instagram/YouTube. To keep up with the current trend I have integrated AI features in it like:
1) Auto Captions
2) Watermark
3) Reaction video(Where you can overlay 1 video over other playing kn background just like those reaction channel guys do.)
4) Merge multiple videos.

All the above things happen at very low cost.
Can anyone recommend a platform where I can sell these?

You can use Affiliate Programs like JVZoo, WarriorPlus or ClickBank or any similar program.

You can also sell them on Forum Market Places like BHW.

I can't say one but I can tell about several good ones. You can sell it on platforms like http://www.gumroad.com/ or https://payhip.com/, which are great for digital products and let you keep most of the revenue. If you’re targeting content creators, listing it on marketplaces like https://appsumo.com/ can give you massive visibility. For niche exposure, head to creator-focused communities like https://www.producthunt.com/ to launch and get early adopters excited. Just show off how easy it is and how much time it saves, and you’ll have buyers lining up!
