Videos help for sure, but you still gotta put them somewhere people will actually watch them. Reddit can work but half those subs ban self-promotion instantly, and Twitter's algorithm hides your posts unless you're already verified or whatever. There's dedicated launch platforms though where the whole point is showing off new products to folks actively browsing for them. You can submit your AI tools here
https://openhunts.com/ . People there are specifically looking to discover what makers and developers are building, so you're not fighting against cat videos and memes for attention. Post what your tools do, maybe throw in a quick demo, and let people come to you instead of chasing them down.
