I built an iOS app that reads your TikTok data export and writes a literary piece about who you are. Launched this week.
Quick share, been working on this for months and it just hit the App Store.
What it does: You request your TikTok data export from settings (the ZIP with every search, watch, comment, follow). You hand the ZIP to the app. About 60 seconds later you get back:
- One headline, a single specific line about you
- Six metrics scored 0–100 (Brainrot, Depth, Mirror, Loneliness, NPC, Niche)
- Seven prose sections, written, anchored to your actual behavior
- A combined Auvre Score
Your tiktok data are deleted immediately after creating your score etc
You can rescan every two weeks and watch yourself change over time.
The hard part: getting the prose specific enough that it produces a "how does it know that" reaction instead of a horoscope. The whole product lives or dies on that moment. Spent most of the build time on the prompt pipeline and the evidence-anchoring step.
To give you a sense of the output, mine came back with the headline "You consume like someone building a personality from scratch, every two months a new identity, the old one abandoned mid-sentence." Brainrot score 58. That one stung in a useful way.
The unhard part I underestimated: the TikTok export flow. Users have to leave the app, request data, wait for 3-8 minutes for the email, come back. Built notifications and a re-entry flow but it's still the biggest drop-off.
Live on the App Store now as Auvre, feel free to comment for the link. Happy to answer questions about the build, the pricing decisions, or the prompt engineering.
What's killed me most: figuring out how to market something where the value is invisible until you've already spent 15 min exporting data.
