Reply on X, LinkedIn and Reddit — without writing them yourself_
One Chrome extension. Three platforms. Pick a tone, get a draft that actually answers the post — not a generic “Great point!”.
Install the extension → open any post → click generate. On mobile? Use the web app.
Works on Chrome & all Chromium browsers. No account required.
Replies are the cheapest growth_
On every social platform, the accounts that grow fastest aren't the smartest — they're the ones that reply the most. More replies means more impressions, more profile clicks, more followers. The problem? Writing good replies takes time. ReplyKit removes the bottleneck on the three platforms where it matters.
“I grew my account from 0 to 1,000 followers in a month using this extension. Replying to 50+ posts a day used to take me hours. Now it takes minutes.”

@FredericTheTallTuned for each platform_
One brain, three voices. The same tone reads differently on X, LinkedIn and Reddit — ReplyKit adjusts length, formality, and what counts as “witty” per platform.
AI will be the most transformative technology in human history. The question isn't if, but when.
the 'when' is already here. the real question is who gets to shape it. open-source models are democratising access faster than any regulation can keep up. the winners won't be the biggest labs — they'll be the builders who ship fastest.
Every company is now a software company. And soon, every software company will be an AI company.
Bold claim, but most companies still can't ship a working CRUD app on time. The gap isn't AI adoption, it's engineering culture. Companies that already move fast will absorb AI naturally. The rest will buy SaaS wrappers and call it transformation.
Learn to sell. Learn to build. If you can do both, you will be unstoppable.
step 3: learn to ship before your competitor tweets about the same idea. most 'unstoppable' founders i know are just fast. the best ones reply to threads like this while their deploy is running.
On your phone too_
Chrome extensions don't run on mobile, so we built a web app. Open it on iOS or Android, paste the post you want to reply to, get a draft. On Android you can also share-sheet from X / LinkedIn / Reddit straight into ReplyKit.
Open the web app →Your account stays safe_
Other “growth tools” auto-post, mass-follow, and scrape timelines. Every platform detects that and bans accounts. ReplyKit does none of it.
