Inki is an AI writing editor for writing that doesn't read like AI. Ask AI right where you write, so there is no copying text between a chat and your document. Keep your draft open and continue, shorten, or polish it in place. With Inki, you can: โข Draft with AI from the cursor and keep writing โข Rewrite selected text: Improve, Shorten, Lengthen, Revise, or Deslop โข Ask the assistant about structure and wording, with web search when you need it โข Review suggested changes as a diff before applying them โข Generate and edit images with AI โข Organize notes in folders and find them with search โข Attach PDFs, images, or photos from your camera for context โข Go back to any earlier version; every rewrite is saved โข Pick up the same documents on the web and in the Mac app Use Inki for emails, articles, proposals, reports, essays, books, and fiction. It works for a short note and for a draft you keep growing. Start with the free plan. A subscription is required for more AI usage. An account is required.

Verdict
The clearest difference is ads: Inki at none against Socratus's shown. Inki also leads on update cadence (every 3 days vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
