Three moves. No copy-paste.
You never leave the editor you're already writing in, and nothing changes except the passages you mark.
Mark
⌥ NSelect a passage that sounds off and mark it. Each one gets its own color, and you can mark as many as you like.
Note
in your wordsTell it what's wrong the way you'd tell an editor, or tap a quick instruction. The note travels with the passage.
Swap
⌥ [ ⌥ ]Hit Rewrite and flip through each model's version right where the passage sits. ⌥⏎ keeps one. ⌥⌫ puts your original back.
Fair questions
Why not ask the chatbot to redo the whole post?
Because most of the draft is fine. SwapDraft only touches the passages you marked, so the parts you already like stay exactly as they are.
Will it wreck my undo history?
No. Flipping through rewrites leaves nothing behind, and after you accept one, a single undo brings your original back. The highlights are never saved into your post.
Which editors does it work in?
In-place rewriting works in the TipTap-based editors we've added support for, and that list is growing. For anything else, paste your text into SwapDraft's built-in document editor, fix it there and copy it back out.
Do I need my own API keys?
No. One SwapDraft account covers every model. Sign in with your email and the extension connects itself.
What does a credit buy?
A credit is half a cent of model cost. You see the estimate before every run, and you're charged for what the models actually used.
What happens to my draft?
It goes to the models you picked so they can write the rewrites. We don't store the article itself, only the rewritten passages that come back. Privacy policy
