Imagine an app that works similarly to TikTok, but each video is fully AI-generated (including any text, visuals, or audio) and personalized for each user. Users don't post comments which other users see, but perhaps they provide feedback on each video via ratings, likes, or natural language, or with a device that monitors brain activity.
In current media apps, AI systems curate user-generated content to create maximally addicting series of inputs. On this platform, the AI system would cut out the meaty middleman by generating the content directly.

Feel free to ask questions if the resolution criteria needs to be clarified.
Update 2026-01-01 (PST) (AI summary of creator comment): The creator has clarified that apps like Sora do NOT qualify for this market because:
Users still generate the content (not the company)
Multiple users watch the same piece of content (not 100% individualized)
Users can still comment
To qualify, an app must have:
Content generated by the company/AI system itself (not user-generated)
100% individualized content (each user sees unique content)
No public commenting system between users

@ImaPerson Ah, I wish I had specified the resolution criteria better. I think the trajectory was almost directionally correct, but even though Sora is exclusively AI-generated shortform content, it’s technically still social. Users still generate the content (not the company), multiple users watch the same piece of content (not 100% individualized), and users still comment. So I think it still counts as a “no”.

> Imagine being able to create a brand new season of your favorite canceled TV series. Or a personalized kids cartoon starring your own family as the characters. Or an AI-native successor to TikTok, where every video is made for exactly one viewer.
