The premise is simple - instead of switching to a separate writing site, you select text wherever you happen to be typing and apply a fix, a reply or a rewrite in a single tap. The feature set covers the everyday writing chores. Fix corrects grammar and spelling; Reply drafts a response to an incoming email or message; Create writes something from a prompt; Edit reshapes existing text. Tonal filters let you dial formality, friendliness and length up or down, and a humanize option rewrites AI-sounding output so it reads more naturally. Summarization handles web pages and PDFs, and templates let you save repeatable instructions. It is aimed at people who write a lot and want less friction: students, support and sales staff, non-native English speakers and users with dyslexia. The company says its tool is used by millions of people and at many large enterprises, offers an Enterprise tier with brand-voice control and account management, and states that it works only with models holding a zero data retention policy. **Pricing & Plans:** Free tier with 5 daily uses of Create, Fix, Reply and Edit, basic tone filters and 1,000-character inputs. Pro costs $24.99 per user per month, or $12.49 per user per month billed yearly at $149.88, adding unlimited uses, advanced editing, 10,000-character inputs and cross-platform history. Enterprise is custom-priced. - **One-tap grammar and spelling fixes:** Select any text in an app, email or message and correct all grammar and spelling errors in one tap instead of reviewing word by word. - **Instant replies:** Generate a contextually appropriate response to an email or chat message instantly, then adjust the tone before sending. - **Tone and style editing:** Sliders and filters adjust formality, friendliness, length, rephrasing and emoji so output matches your personal voice. - **40+ languages:** Write and translate content in more than 40 languages through input and output language settings, which is especially useful for ESL users. - **Reusable templates:** Templates let you store reusable instructions so recurring writing tasks produce consistent, tailored output at scale. - **On-the-fly summarization:** Condense web pages, PDFs and long documents into key points without leaving the writing surface. **Strengths:** Works system-wide via keyboard and extension, so it fits existing apps; Covers grammar, replies, rewriting, translation and summarization in one tool; Strong fit for non-native speakers and users with dyslexia; Free tier is genuinely usable with no card required **Limitations:** Pro pricing is on the higher side compared with some general-purpose writing tools; Free tier is capped at 5 uses a day and 1,000 characters; Best experience depends on installing the keyboard or browser extension; Enterprise features require contacting sales [Profile (Markdown)](https://openaitools.app/tool/paragraphai.md) ## Write Brain Write Brain is a lightweight writing assistant that lives inside your browser as a Chrome extension. Rather than asking you to paste text into a separate app, it attaches a small menu of improvement commands to whichever text box you are already typing in. That means it can help while you are composing a LinkedIn post, replying in Gmail, leaving a YouTube comment, or filling out an online form. The core idea is speed. You type naturally, then use the extension to clean up grammar and typos, remove fluff, sharpen your wording, or change the tone so it fits the context. Because it works in place, you avoid the copy-paste round trip that standalone grammar checkers require. Beyond proofreading, Write Brain adds a few creative touches: it can translate text to or from your home language, which is handy for reading foreign comments or answering international customers, and it can suggest emoji for headings and list items. It is a general-purpose helper for people who write a lot on the web and want quick, low-friction improvements rather than a full document editor. **Pricing & Plans:** Freemium. The extension is free to install from the Chrome Web Store, and the store listing indicates in-app purchases are available for paid features or higher usage limits. - **One-click grammar fixes:** Automatically spot and correct typos and grammar slips in any text field and fix them with a single click before you send. - **Conciseness and clarity:** Strip out verbose corporate phrasing and unnecessary words to turn rambling drafts into clear, direct messages. - **Writing enhancement:** Turn a rough outline into richer, more descriptive prose with quick suggestions on how to phrase your point better. - **Inline translation:** Translate text in place, so you can read foreign-language comments or reply to customers in their own language. - **Emoji suggestions:** Get context-appropriate emoji suggested for paragraph endings and as bullets for list items to add personality. **Strengths:** Works directly inside any website's text fields, no copy-paste required; Covers grammar, conciseness, tone, translation, and emoji in one menu; Fast, one-click improvements suited to short-form and social writing; Lightweight browser extension with a simple learning curve **Limitations:** Requires installing a Chrome extension before most features work; No dedicated desktop or mobile app; Feature set is narrower than full document editors like Google Docs add-ons; Grammar and rewrite quality can miss nuanced or technical language [Profile (Markdown)](https://openaitools.app/tool/write-brain.md) ## Frequently Asked Questions ### How do ParagraphAI and Write Brain compare in monthly traffic?
