Same message, two outcomes

Feel like a copy and paste Bot.

Write it, paste it, ask for a fix. Not quite right. Try again. Slow, distracting, and it dulls your voice.

CLAIMS VS REALITY

Promises tested against reality

Left, what other tools claim. Right, how BetterCopy answers it: security, privacy, your terms.

the promise
"we don't sell your data"
✗ it still sits on their servers, waiting to be breached, sold, or subpoenaed.
Privacy Shield
Names, numbers, and sensitive details are masked before any text leaves your machine, then restored after.
How it protects you →
the promise
"runs securely in the cloud"
✗ "securely" still means your text left your computer.
Local LLM
The model runs on your device. Offline capable, zero cloud, zero data leaving your computer.
Run it offline →
the promise
"your data, your rules"
✗ on their model, under their terms, at their price.
Custom API Key
Bring your own key. Your text goes straight to your provider, under your terms and billing.
Bring your own key →
the promise
"writes just like you"
✗ the same "you" they gave everyone else.
Personal Style Memory
Learns your tone from the fixes you accept, stored locally. The more you write, the more it sounds like you.
How it learns you →
the promise
"keeps your brand voice"
✗ until it "corrects" your product name into something else.
Smart Word Guard
Product names, technical terms, and signature phrases are protected from ever being "corrected" away.
Guard your words →
the promise
"you're always in control"
✗ try deleting your data. see how long that takes.
You own your data
Style history lives on your device, with backup and restore in your hands. Export it, move it, delete it.
Your data, your hands →

Every answer above runs on the same backbone. Now, meet the brain.

I stopped pasting everything into a chatbot tab. I select, tap the shortcut, and my message reads sharper while still sounding like me.

Client proposals used to take me an hour of rewriting. Now I draft fast, enhance in place, and send. The privacy controls sold me.

Rocky first day, it kept a phrase I wanted changed. Once I set my tone it has been a genuinely good experience, every reply goes through it now.
