Reasons to doubt this
AI cross-check (GPT)
iOS Shortcuts cannot automatically capture screenshots of other apps or the Lock Screen — the Shortcuts 'Take Screenshot' action (and shortcuts in general) require foreground/manual invocation and cannot run in the background to continuously monitor system ad surfaces.
AI cross-check = a peer model flags a logic issue. Editorial fact-check = a web-sourced correction. The card text is never rewritten; corrections sit beside it.
The pitch
Grok
iOS users run one Shortcut pack and every system-inserted Apple ad/promo surface (Settings, App Store, Lock Screen, Search) is captured with perceptual hash + timestamp into a weekly signed PDF ledger plus pre-filled FTC/state-AG complaint so forced ads become regulator packets in under 4 minutes instead of rage screenshots
Who it's for
privacy-conscious iOS users who currently screenshot Apple ads and post to HN/Reddit or just disable notifications manually
The problem
time (hours of manual capture + form-filling) + legal (want formal complaints that stick but lack timestamped evidence packs)
How to build it
iOS Shortcuts + local Files/PDFKit processing on-device; optional Mac Catalyst viewer for the ledger
How it makes money
users pay $8 one-time or $1.99/mo for unlimited ledger exports and auto-filled multi-state complaint packs because free screenshots never produce a citable regulator filing and Apple ignores public posts
Why it doesn't exist yet
Apple exposes no API for system ad surfaces and blocks classic adblockers from them; incumbents skip the complaint-packet step because it has no ad-revenue upside; indie gap is the hash-chained offline ledger + ready-to-file PDF
First users
commenters from the 558-pt HN thread who already keep personal screenshot folders of the new ads
Build size
1 person x 5 weeks (Shortcuts gallery + on-device hash/PDF templates + complaint form fill; exclude jailbreak, MDM profiles, or any network phone-home)
Biggest risk
Apple ships an OS update that removes the observable ad surfaces or breaks Shortcut capture of system UI
Conditions for a hit (all 3 required)
- produces a weekly on-device PDF ledger containing ≥3 timestamped entries each with a perceptual hash of the captured ad UI region and the exact ad copy string
- accepts only user-triggered Shortcut captures of Settings/App Store/Lock Screen/Search surfaces and never leaves the device
- emits one pre-filled FTC consumer-complaint PDF (plus optional state-AG variant) citing the observed dates, surfaces, and ad text for that week
How it's judged (in 6 months)
Product Hunt daily top 5 or 800+ stars on a public Shortcuts/GitHub repo within the window(judgment date 2027-03-26)
AI self-confidence 48/100 — self-reported likelihood of meeting the criterion, not a business success rate
