Marketing ideas on how to make an app go viral

Hey y'all, so spent the weekend building TLDWYoutube, a tool to generate summaries, transcripts, and highlights of Youtube videos.

I've been trying to get the app go viral but have been gotten stuck on how to effectively get usage on it. What are your ideas how to get an app to go viral without spending money on ads?

Here are some things that helped drive initial traffic:

1. Posting on Reddit (r/sideproject, r/Youtube, etc)
2. Posting on socials (X/Twitter, ProductHunt)
3. Making the app friendly to access (e.g. add TLDW before any Youtube URL like tldwyoutube.com/watch?v=bAN3KmTSy2Q

Some things I'm considering are:

1. Creating a Reddit/Twitter/Discord bot for TLDW that users can call to generate summaries
2. Posting videos on TikTok/Youtube Shorts

It seems like more and more consumers apps are being discovered through short form content so I plan to leverage that as much as possible.
