On-device comedy workshop
RoastLab
The Lab is open. A private comedy workshop powered by on-device Apple Intelligence. Pick a tone, pick a theme, and generate comedic roasts that never leave your iPhone.
13+ comedic content. Do not roast people without their consent. RoastLab is a creative writing tool, not harassment software.

Tone slider
Slide from clean to spicy. RoastLab adapts the heat of every roast so the punchline matches the room.
Theme picker
Office, family, friends, roommates, or open mic. Pick a context and the writer-in-a-box tunes the angle.
Nothing you write leaves the phone
No analytics, no IDFA, no account, and no cloud copy of your material: generation runs on the device and favorites stay there. The only thing that reaches a server is the App Store purchase record Apple sends so a subscription can be restored.
How a roast flows
Four surfaces that move a comedy writer from blank page to a shareable punchline, with the writing generated on the device.
01
Lab setup
Name a subject, pick a theme chip (Office, Family, Friends, Roommate, Open mic), and set the tone slider. No account, no sign-in.
02
Generate
Tap Roast. Apple Foundation Models writes locally on-device. Drafts appear in seconds. Re-roll until a line lands.
03
Favorites
Save lines you want to keep. The favorites shelf is a local-only writing notebook. No cloud sync, no recovery.
04
Share as image
Render a roast as a styled card and drop it into Messages, Notes, or Instagram. The export stays in the iOS share sheet.
Weekly $2.99 with 3-day free trial. Yearly $19.99.
RoastLab is paywall-first by design. Subscriptions auto-renew via your Apple ID. Generation, favorites, and shared cards never leave the device. We don’t see what you write: generation runs on the device, and the only thing that reaches a server is the App Store purchase record Apple sends so a subscription can be restored.
Pro fair-use generation limits: 100 per day, 200 per week, 500 per month. All on-device.
