ParagraphAI is an AI writing assistant built for people who write every day at work: sales reps replying to leads, customer service teams handling inboxes, ESL professionals writing in a second language, and employees at companies like Pepsi, Meta, RBC, and Cushman & Wakefield who need consistent on-brand communication. The tool has more than one million users, is trusted at NASA and over 25% of Fortune 500 companies, and holds a 4.7/5 rating from over 9,100 app store reviews. ParagraphAI positions itself as the world's first GPT-powered AI writing app and AI keyboard, and it is the only tool in its category that combines native mobile and desktop access, an AI keyboard, and unlimited fix/reply/edit in a single account. The Pro plan costs $12.49 per user per month billed annually at $149.88 per year. Enterprise pricing is custom.

How It Works

ParagraphAI is accessible through three surfaces that sync under a single account: a mobile app on iOS and Android, a Chrome extension for browser use, and the standalone web app at app.paragraphai.com. The four core actions are Create (generate content from a prompt), Reply (read an incoming message and draft a response), Fix (one-tap grammar and spelling correction), and Edit (adjust tone, length, and style in real time). The AI Keyboard is a separate install on mobile that puts Reply, Fix, and Edit directly inside any app you are already using, including Gmail, Slack, WhatsApp, Telegram, iOS Messages, Instagram, and Salesforce, so you never have to leave to get writing help. Translation covers 40+ languages by setting your input and output language independently, which means you can write a prompt in Spanish and receive output in English, or any other combination. The Summarize feature condenses web pages and PDFs to key points without leaving the app. The Humanize feature rewrites AI-generated text to read as natural human writing and avoid being flagged by AI detection tools. Custom Templates let you save reusable prompt instructions for consistent outputs across any text field. The Free plan allows 5 uses per day of each action with a 1,000-character input limit; Pro removes the daily cap and raises the input limit to 10,000 characters.
