Stop wasting time

Why copy-paste to AI when you don't have to?

Every time you switch tabs to fix your writing, you lose focus. WriteZap does it right where you're typing.

The Old Way

Copy → AI tab → Paste back

~0s

average time

Copy text
Open ChatGPT or Claude
Paste & type your prompt
Wait for AI response
Copy the result
Switch back & paste

Context lost. Every tab switch breaks your flow and interrupts creative thinking.

The WriteZap Way

Select → Shortcut → Done

~0s

average time

Select your text
Press the shortcut
Done — text replaced

Stay in flow. Your writing is fixed right inside your app. No tab switching. No copy-pasting.

That's 10x faster — and you never leave the app you're writing in.

Grammar & Spelling

Fix grammar, spelling, and punctuation — instantly

No copy-pasting to AI tools. No browser extensions that read your private messages. Just select, press the shortcut, and watch your writing transform.

One shortcut, zero friction

Select text anywhere, press the shortcut, and grammar is fixed in under 2 seconds. No menus. No sidebars.
