What is Walter Writes AI?
Walter Writes AI is a web platform for editing and checking AI-assisted writing. Its humanizer takes a draft produced by a chatbot and rewrites it at the level of sentence structure, word choice and rhythm, with three strength settings (Simple, Standard and Enhanced) and an aim of keeping the original meaning and tone. Its detector reads a passage and gives an estimate of the probability that AI wrote it; the score appears right after a rewrite. Related tools include a paraphraser, a grammar checker and a resume rewriter, and there are mobile apps for iOS and Android, a Chrome extension, a Zapier connection and MCP connectors for Claude and Codex. Developers can use APIs for humanizing and for detecting AI text, images and voice. Subscriptions are sold by monthly word allowance, from Starter to Teams.
