WriterPi — AI Sidebar: Writing, Replies & Chat

AI sidebar in every tab. Draft replies, summarize pages, write emails, chat with AI. Free to start, $1 to upgrade.

WriterPi is an AI sidebar that lives inside your browser. Instead of switching to another tab to ask ChatGPT, WriterPi reads the page you're already on and helps you write, reply, summarize, or answer questions in place. WHAT IT DOES Write drafts. Draft an email while you have your inbox open. Compose a post while you're on a social network. Write a blog post while you're already in your editor. Reply faster. When someone messages you, WriterPi reads the conversation and drafts a reply in your tone. Summarize any page. Reading a long article? Ask WriterPi for the key points in five bullets. Translate. Translate a page or a selection into more than twenty languages. Ask about images. Describe an image on the page or ask questions about what's in it. Pick a tone. Choose from professional, casual, friendly, funny, concise, detailed, and a real Gen Z voice that doesn't sound corporate. WHO IT'S FOR Students writing essays and reports. Professionals drafting messages at work. Marketers writing social copy. Freelancers responding to clients faster. Anyone who uses AI chat tools for daily writing tasks. WHAT MAKES IT DIFFERENT WriterPi reads the actual page before it answers. That means the answer is grounded in what you're looking at right now — not a general response you have to edit. It works everywhere you already write. The Gen Z tone actually sounds like Gen Z, not a marketing team's guess at Gen Z. No login is needed to try it. Ten free messages get you started. Sign up free to get twenty-five messages every month. Paid plans start at one dollar for a three-day pack. That's a real price for real work. PRIVACY Pages are only read when you ask. No page content is stored on servers. There are no ads. There is no tracking. There is no data selling. PRICING Free tier: ten messages with no signup.
