Your creative work trains someone else's AI
The Editor's Knife is the answer
Drafts, designs, compositions, scripts. Cloud platforms use your creative output to train models that compete with you. Work locally. Own every draft, every iteration, every idea. Nothing uploaded, nothing scraped, nothing trained on.
The Editor's Knife is a single-file knife with 5 tools that runs entirely in your browser. The Editor's Knife gives editors and writers five practical tools in a single HTML file. Search and replace with full regex support, detect clichés and filler words with highlighted previews and clean scores, analyse sentences for passive voice, long constructions, adverbs, and hedging language, check for consistency in spelling and terminology variants, and enforce custom house style rules with presets for AP, Chicago, and Tech — all offline, all private, all yours forever.
