Three presets — Chill, Balanced, Aggressive — or fine-tune all 13 parameters yourself. Your strategy, your settings.

No accounts. No backend. No data leaves your browser. Everything runs locally in Chrome.

Common questions

No. ReplyX never posts, replies, likes, follows, or takes any action on your Twitter account. It's a read-only analytics layer. You decide what to reply to and write every word yourself.

No. ReplyX doesn't write anything for you. It scores and surfaces tweets worth replying to — what you say is entirely up to you.

No. ReplyX doesn't interact with Twitter's API or automate any engagement. It scores tweets based on publicly visible metrics as you scroll your timeline. It's no different from you eyeballing which tweets are trending.

None. Everything runs locally in your browser. There are no accounts, no backend, and no data ever leaves your machine. We couldn't see your data even if we wanted to.

Not even close. ReplyX is a Chrome extension that adds a scoring overlay to your existing Twitter timeline. Think of it as a highlighter, not a robot.
