AI Copywriting

Every AI edit is shown as a tracked-change suggestion you can accept or reject, so the AI never silently rewrites your document
Full word processor with DOCX import and export, real typesetting, tables, images, math, and page-layout controls
Access to current GPT, Claude, Gemini, and Grok models in one editor with the ability to switch at any time

Browser-only, with no dedicated desktop or mobile app
Free AI usage is limited to a daily allowance, so heavy editing requires a paid plan
Paid plans are metered by AI usage, which can be harder to predict than a flat seat price
