You type one normal thought. GramBook ruins it in ten different ways.
Say something you would actually say. "Someone took my parking spot." It comes back in every dialect of the internet: the fake-deep inspo caption, the corporate leadership lesson, the forum thread where you are always the victim, the hot take that gets you ratioed in your sleep. Same thought. Ten personalities. Each one scored, from "based" to "red flag."
Most of them you just laugh at and scroll past. Every so often one is too good to waste, and you can post it for real and tell no one it came from here.
No cloud. No sign-up. No tracking. With Apple Intelligence on, the rewrites get genuinely unhinged. With it off, GramBook falls back to its own on-device writing and keeps going with the wifi unplugged.
The cast: delulu.solulu, @parasocial.king, you.but.employed, u/well_actually_you, just.had.coffee, your.auntie, you.got.monetized, mod.exe. Plus two originals. Unhinged, who is posting through it. Based, who touched grass and will not stop telling you.
GramBook is a parody. Not affiliated with, endorsed by, or connected to any platform it imitates. Obviously.
Found one you love and hate at once? Tap it for a clean share card. Your innocent thought up top, the damage underneath, ready for the group chat or a viral meme post.
$1.99, once. No subscription. No ads. Just you and the AI in your pocket, goofing around.
Supported languages*: English, Español, Français, Deutsch, Português, 日本語, Italiano, 한국어, 简体中文, 繁體中文, Tiếng Việt, Nederlands, Türkçe, Svenska, Dansk, Norsk
* Without Apple Intelligence enabled, only English post templates are available.
