Chrome extension that drafts on-brand social comments in one click
The extension reads the specific post before writing, so drafts reflect that content instead of a generic template.
Tell it how you write and it aims for your tone or your brand's tone rather than a neutral AI register.
Choose what the comment should do, such as agree, disagree or add insight, and how it should sound.
It works as a browser extension layered on the platform and never asks for your login credentials.

One AI assistant that plugs ChatGPT, Claude and Gemini into every tab
Switch between GPT, Claude, Gemini, DeepSeek, Mistral and Llama class models from a single interface instead of juggling separate subscriptions.
Summarize articles, YouTube videos, PDFs and documents in place, then ask follow-up questions grounded in that content.
Draft and reply to emails in Gmail, compose posts and comments for X and LinkedIn, and repurpose web pages or videos into blogs and articles.
Generate images from prompts using more than 20 image models and multiple aspect ratios for web and social output.
