iPhone
Knower turns any photo on your phone into a hilarious AI-generated edit. Pick a picture, type what you want to happen in plain everyday words, and Knower brings it to life in about ten seconds.
No editing apps, no prompt engineering. If you can text a friend, you can prank one.
WHAT YOU CAN DO
- Make the fish in your buddy's photo twice as big
- Turn your dog into a 300-pound bear
- Make grandma a viking warrior
- Add a giraffe to your cousin's wedding photo
The edits look photorealistic — not cartoon, not obviously fake. They look like real photos that just happen to be impossible. Drop one in the group chat and wait for the reactions.
HOW IT WORKS
1. Tap to add any photo from your camera roll
2. Type what you want to happen in plain language
3. Tap generate
4. Save, share, or use the result as input for another edit
CREDITS
Every new user gets 30 free credits to start. After that, credits come in packs available through the App Store. Images cost 10 credits each. Credits never expire.
PRIVACY
Photos you upload are sent to our AI provider for processing and are not retained. We don't store your photos, we don't train models on them, and we don't share them. Your generated results live in a local library on your device — clear it anytime in Settings.
You can delete your entire Knower account, including all server-side records, from inside Settings → Delete Account.
KEEP IT KIND
Knower is for harmless pranks among friends. Don't use it to harass, defame, or impersonate real people. Outputs depicting nudity, graphic violence, sexualized minors, or recognizable real people in compromising scenarios are blocked automatically.
