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.

One-click ChatGPT replies for Twitter and X posts
Select any tweet, open Replizen and get a written reply in a single click instead of starting from a blank box.
Choose from more than 500 style, tone and length combinations to match the voice you want to project.
Replies are tailored to the specific post you have selected, so the response stays on topic.
Generate the reply, then tweak the wording before posting so it still sounds like you.
