AI reply generator

An AI reply generator that sounds like you

⚡ sits under every post on X and Threads. One click — a reply drafted in your voice, lowercase quirks and all. You press send. Then it learns which replies actually earned you engagement.

What it is: yapmaxxer is a Chrome extension that puts a draft button under every post in your X and Threads feed. It generates replies in a voice profile trained on your real posts, shows which replies earned likes and reply-backs, and — optionally — can autopilot the timeline with human pacing. Free for 3 replies a day; $9/mo unlimited.

How it works

  1. Train your voice — paste 10–20 of your real posts in the options page. It builds a voice card: cadence, casing, emoji use, the words you actually say.
  2. Scroll your feed like normal — under every post there's a ⚡. Click it, get a reply that reads like you wrote it on a good day.
  3. You press send — always the default. Or flip autopilot on and it browses + replies itself, with cooldowns, hourly caps and session breaks.
  4. It learns — the studio tracks likes, reply-backs and views on everything sent. Winning angles get reused; losers quietly retire.

Why not just paste tweets into ChatGPT?

Because ChatGPT starts from zero every time. No feed context, no memory of what you sound like, no idea which of yesterday's replies worked. yapmaxxer is opinionated in the other direction: it's inside the feed, it already knows your voice, and it keeps score.

What you get

Safety, honestly

Automated replying at scale can trip platform automation rules — that's true of every tool in this category, including us. That's why the defaults are conservative: draft-first, human-paced autopilot, hard caps. If you want zero risk, leave autopilot off — it's still the fastest way to reply well by hand.

Try it on your own timeline

3 replies a day is free forever — no card, no trial clock. Load the extension, open x.com, and read what it writes in your voice.

What is an AI reply generator?

How is it different from ChatGPT?
Feed-native, voice-trained, and it learns which replies earned engagement. ChatGPT is a blank box you paste into.
Does it work on Threads?
Yes — same extension, same voice profile.
Will it make me sound like a bot?
The voice card trains on your real posts — lowercase, fragments, your slang. It writes like you on a decent day, not like a LinkedIn comment.
