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. It only touches the passages you mark, and everything you already like stays exactly as it is.

Mark a passage that sounds off, say what is wrong in your own words or tap a quick instruction such as "Make this punchier" or "Cut the fluff", then hit Rewrite. Each marked passage goes to several AI models at once. You flip through each model's version right where the passage sits, then accept one or keep your original. After you accept, a single undo brings your original back, and the highlights are never saved into your post.

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

No API keys needed: one account covers models including GPT-6 Luna, Claude Sonnet 5.5, Gemini 3.5 Flash and Grok 4.7. Rewrites use credits, with an estimate before every run. Free to start with no card: 100 credits at signup plus 40 every week and 2 models per rewrite. Pro is $19/month for 1,500 credits, up to 5 models per rewrite and all 9 models. SwapDraft does not store your article, only the rewritten passages that come back.
