Growing on 𝕏 is a grind.

You open a viral tweet in your niche. Hundreds of potential followers in the replies. Now you have to click into each profile, check their follower count, decide if they're worth following, hit follow, go back, and repeat — hundreds of times.

Features

Everything you need to grow faster.

No more tab-switching. No more manual grunt work. FollowKit puts it all inline.

One-Click Follow

Follow any user directly from a post's reply thread — no profile visits needed. Your follow list syncs automatically.

Inline Follower Badges

See a color-coded follower count next to every username on your feed. Instantly identify high-value accounts vs. bots.

AI Reply Generation

Generate contextual, on-brand replies with a single click. Set your tone, add a pre-prompt, and let GPT do the writing.

Rate Limit Dashboard

Live progress bars and countdown timers keep you aware of X API limits so you never hit a wall.

Privacy-First

Your X credentials never leave your browser. The Cloudflare Worker only proxies AI generation — nothing else.

Know who you're following — at a glance.

Color-coded badges let you instantly prioritize high-value accounts and skip bots.

If you're using 𝕏 as a distribution channel, this is your unfair advantage.

Questions? Answered.

Yes, it's completely free right now. Use it as much as you want.
Absolutely. The extension tracks your follow and user-lookup rate limits in real time with live countdown timers, so you always know exactly how many actions you have left.
Your X credentials never leave your browser. The extension uses your active session cookie — it never asks for your password. The only external call is to a Cloudflare Worker for AI text generation, which doesn't receive any X credentials.
Currently Chrome and any Chromium-based browser (Edge, Brave, Arc, etc.). Firefox support is planned.
When you click the sparkle button next to any reply box, the extension sends the tweet context to a secure Cloudflare Worker that calls OpenAI's GPT-4o-mini. You can set a pre-prompt (e.g., your product pitch) and a tone (casual to formal), and the AI generates a reply under 180 characters — snappy and engagement-optimized.
