Short answer: market an AI app by showing a real input and a real output in the first seconds. Demo-first videos (type, tap, result) beat explanations. Only show results the app actually produces, and follow each platform's AI disclosure rules: TikTok requires realistic synthetic media to be clearly disclosed, and YouTube requires disclosure of realistic altered or synthetic content.
Demo-first content
| Format | Structure | Example (made-up photo app) |
|---|---|---|
| Input → output | Show the prompt or photo, then the result | "Old blurry photo → restored" |
| Side-by-side | Before and after split screen | Original vs restored |
| Speed run | "3 tasks in 30 seconds" | Resize, restore, remove background |
| Real use case | A person with a problem uses the app | "Fixing grandma's wedding photo" (with permission) |
| Honest limits | What it can't do yet | "It struggles with text — here's why" |
The honest-limits format builds trust and gets comments. Keep screen recordings clean (screen recording guide).
Show real outputs only
- Record the actual app, not a mockup.
- Don't cherry-pick a one-in-fifty result and imply it's typical. Say "best of several tries" if that is what it was.
- Use input images and voices you own or have permission to use. Never feature a real person's likeness without consent.
Disclosure rules to know
TikTok. "Synthetic or manipulated media that shows realistic scenes must be clearly disclosed," for example with a sticker or caption (Community Guidelines, as of 17 September 2026). TikTok also launched a dedicated AI-generated label for creators in 2023 (TikTok Newsroom, as of 17 September 2026).
YouTube. Creators must disclose content that makes a real person appear to say or do something they didn't, alters footage of real events, or generates a realistic scene that didn't occur. Using AI for scripts, titles or thumbnails doesn't need disclosure; you set it under "AI use" in YouTube Studio (YouTube Help, as of 17 September 2026).
Instagram. Meta applies an "AI info" label when it detects industry-standard AI indicators or when people disclose AI-generated uploads (Meta, as of 17 September 2026).
| Video content | TikTok | YouTube | |
|---|---|---|---|
| Screen recording of the app | Not synthetic media | No AI disclosure needed for the recording | Not synthetic media |
| Realistic AI output shown on screen | Disclose if realistic | Disclose if realistic | May be labeled; disclose |
| AI voiceover that sounds like a real person | Disclose | Disclose if it imitates a real person | Disclose |
| AI-written script only | No label needed per rules above | Not required | Not required |
When in doubt, disclose. A line in the caption costs nothing.
No fake humans
Don't run an AI-generated persona presented as a real human user of your app. If you use an AI presenter, say so on screen and in the bio. Also turn on TikTok's commercial content disclosure on promotional posts.
Posting AI app demos at volume
When you have many demo variants, Farmero posts them from your own iPhones through the real apps, applies per-post settings you choose (who can view, comments, caption) and reads them back, refusing settings it can't apply. Put AI disclosures in the caption or on the video itself. See faceless accounts for apps and posting.
FAQ
What content works best for AI apps?
Input-then-output demos in the first seconds, plus honest comparisons. Results vary and aren't guaranteed.
Do I have to label every AI app video?
Label realistic synthetic media per each platform's rules. A plain screen recording of your app is not the same as synthetic media, but disclose when unsure.
Can I use an AI avatar as a spokesperson?
Only if it's clearly disclosed as AI. Don't present it as a real person.
Does AI disclosure hurt reach?
YouTube says its disclosure doesn't affect monetization or reach. Other platforms don't publish a comparable statement.
