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.
