What is Grammar Checker & Proofreader?
PowerPen is a ChatGPT‑powered Android grammar checker and AI proofreading app that helps users rewrite, condense, or expand text while fixing grammar, spelling, and punctuation errors. It acts as an AI writing assistant for emails, social media messages, work tickets, product descriptions, and study‑related communication, letting you quickly improve tone, clarity, and correctness directly from your phone.
The app offers multiple rephrasing and language‑style tools, including casual, professional, intimate, flirty, warm, friendly, and passive‑aggressive tones, so you can adjust the same message to fit different audiences or contexts. You can also shorten or lengthen text, summarize long articles or research papers, and generate AI‑assisted copies for emails, tweets, and other social‑media responses.
PowerPen targets students, professionals, copywriters, and non‑native English speakers who want to polish their daily writing, increase clarity, and avoid language errors without switching between separate tools. By combining grammar checking, paraphrasing, summarizing, and tone‑adjustment features in one interface, it positions itself as a compact but fairly complete AI‑powered writing assistant for mobile use.

Can I shorten or expand my text with PowerPen?
Yes, PowerPen provides both a Shorten Text and a Lengthen Text feature. The Shorten Text tool condenses your content into clearer, more concise paragraphs, while the Lengthen Text option rewrites and expands your text to meet higher character or word‑count requirements using AI paraphrasing.
Is PowerPen free to use?

Additional word‑count capacity and expanded usage are unlocked through in‑app purchases, though specific pricing and plan tiers are not detailed on the store page.
Who is PowerPen best suited for?
PowerPen works well for students, professionals, copywriters, and non‑native English speakers who frequently write emails, work tickets, product descriptions, or social‑media content and want quick AI assistance to polish tone, clarity, and correctness. It is especially useful for users who prefer to handle most of their writing and editing on a mobile device.
Can I use PowerPen for marketing or sales copy?
Yes, PowerPen supports marketing and sales copy by offering a direct‑tone mode free of passive language, along with an AI copywriting and message‑generation feature. You can generate or refine ad creatives, offers, product descriptions, and promo emails in a more persuasive, sales‑oriented style.
Does PowerPen require an internet connection?
PowerPen relies on ChatGPT AI technology, which implies it needs an internet connection to process and rewrite your text, since the AI runs on remote servers rather than entirely on the device. The store description does not advertise an offline mode, so continuous connectivity is expected for full functionality.
How does PowerPen handle privacy and data?
According to the Play Store listing, PowerPen may collect and share certain data types such as location, financial information, and app activity with third parties, and data is encrypted in transit. Users can also request that their data be deleted, and the developer indicates that data‑privacy practices may vary by region and age.
Is PowerPen available on iPhone or desktop?
PowerPen is currently listed only as an Android app on Google Play, with no indication of an iOS or dedicated desktop version. This means it is designed for use on Android phones and tablets rather than iPhones or standalone computer applications.
