SwapDraft

SwapDraft is a Chrome extension for bloggers and newsletter writers who draft with AI and then have to fix the parts that sound like AI. Most of a draft is usually fine, so there is no reason to have a chatbot redo the whole post. SwapDraft only touches the passages you mark, and everything you already like stays exactly as it is.

How it works

• Mark: select a passage that sounds off. Mark as many as you like.

• Note: say what is wrong in your own words, or tap a quick instruction such as "Make this punchier" or "Cut the fluff".

• Swap: hit Rewrite, and each marked passage goes to several AI models at once. Flip through each model's version right where the passage sits, then accept the one that works or keep your original.

Flipping through rewrites leaves nothing behind in your undo history, and after you accept one, a single undo brings your original back. The highlights are never saved into your post.

Where it works

In-place rewriting works in the TipTap-based editors SwapDraft supports. For any other editor, paste your text into SwapDraft's built-in document editor, fix it there and copy it back out.

Models and pricing

You do not need your own API keys. One SwapDraft account covers every model, including GPT-6 Luna, Claude Sonnet 5.5, Gemini 3.5 Flash and Grok 4.7. Sign in with an emailed link, no password. Rewrites are paid for in credits: you see an estimate before every run and are charged for what the models actually used.

Free to start, no card needed: 100 credits when you sign up, topped up by 40 every week, and 2 models per rewrite. Pro is $19 per month for 1,500 credits a month, up to 5 models per rewrite and all 9 models. SwapDraft does not store your article, only the rewritten passages that come back.
