Fix my words. Keep my tone.

SamePen rewrites your everyday messages in your own voice — like you, on a good writing day.

How it works

Three steps, none of them clever

1

Paste your draft

Drop in your rough message. Add the one you're replying to, if context helps.

2

Set the tone

Two sliders — directness and warmth. Nudge them until the mix feels right.

3

Pick a rewrite

Two versions side by side: a light edit that tidies your text, and a full rewrite. Keep the one that sounds like you.

AI that picks up your pen — not its own

It learned from you, so it writes like you

Most AI rewriting averages everyone's writing into no one's: the same padded openings, the same tidy sign-offs. People can tell — a message that doesn't sound like you reads worse than one with typos.

SamePen builds a personal voice profile from samples of your own messages and rewrites inside those habits instead of over them. And it's not a black box — every rule it learned is right there to read, and yours to edit.

Your voice profile learned from samples of your writing
✓how you greet
✓sentence length
✓favorite words
✓punctuation quirks
✓how you sign off

Every rule visible. Every rule editable.
