AI autocomplete that finishes your sentences wherever you type
Finish sentences inline in any text field across your browser, from email clients and docs to chat and CRM tools.
Produce full paragraphs, replies, or documents from a short prompt without leaving the page you are working on.
The engine learns how you write and suggests phrasing that sounds like you rather than generic AI output.
Works as a browser extension, so there is no new app to adopt and no per-tool setup for the sites you already use.

Free, signup-free AI replies for LinkedIn, Twitter/X and Instagram using your own OpenAI key.
Open the extension icon in the comment interface on LinkedIn, Twitter/X or Instagram and it drafts a reply for that specific thread.
Paste your own GPT API key in the extension settings — no account, no proxy server, and no data collection per the developer's disclosure.
Write instructions to match your brand voice or personal persona so generated comments sound like you rather than a default chatbot.
Runs as a lightweight Chrome extension (about 24 KB) directly in the sites you already use, so there is nothing heavy to install or manage.
