On X
What Reply Monk does
Replies where you read, posts and threads in the web app, and a quick check before anything goes out.
-
A reply bar on X
In the extension, a bar appears on the reply box and on the new-post box. Pick an intent, shape the length and tone, and the draft streams in. It works on x.com and twitter.com.
-
Posts and threads
Get a first draft from a topic, rewrite it, try hook options, or turn an idea into a thread with a hook and call-to-action score. Preview the post or thread before you copy it.
-
Reply Studio, no extension needed
Paste the post you want to answer, pick what the reply should do and get three replies in your voice. Works on a phone too.
-
Save posts, draft from them
A bookmark button saves a post to your swipe file. A pen button turns a post you are reading into a draft in the web composer.
-
A pre-post check
“Ready to post?” checks length and thread rules and flags stock AI phrases. It is free and makes no AI call.
-
Reminders and results
Get a “Time to post” reminder at the time you chose. Afterwards, type in your numbers, import your X archive or have a screenshot read.
How it works
How a reply on X gets writtenin your voice
The same four steps in the reply bar and in Reply Studio.
-
Teach it how you write
Paste a few of your posts or import your X archive. It needs at least three posts to learn from.
-
Say what it should do on X
Choose an intent: Add an insight, Ask a question, Agree and add, Disagree politely or Congratulate. Then set a length, emoji amount and whether to use hashtags.
-
Read it and make it yours
The draft shows which voice version and persona wrote it. Edit anything. The words you change become new samples, so the voice keeps learning from you.
-
You press post
With the extension, the reply lands in the box and you press X’s own Post button. From the web app, X opens with your text filled in and you press post.
Your voice
It writes like you because it learned from you
The Voice page shows what Reply Monk picked up from your writing and lets you correct it. This is sample data.
- Learns from your posts and from your X archive
- A voice chip in the reply bar tells you whether your voice is on or replies are generic
- A “never say” list for words you hate
- Edits you make before posting teach it more
Honest limits
Where Reply Monk stops,on purpose
It is a writing tool, not an automation bot.
What it does not do
- It never posts, likes, follows or replies for you. You press X’s own button.
- It does not run bulk or scheduled actions in your feed.
- Scheduling sends you a “Time to post” reminder. It does not publish for you.
- From the web app, X opens with your text filled in. For a thread, that is the first post, and you post the rest yourself.
- Your numbers come from you: typed in, imported from your X archive, or read from a screenshot. Reply Monk does not scrape them.
Good to know
Whatever you post still comes from you. Reply Monk drafts, and you decide what goes out under your name.
Questions
X, answered
Anything else? Email us and a person will reply.
Can AI reply on X in my own voice?
Reply Monk learns your style from your posts or your X archive and uses it on every draft. It shows whether your voice was used. You read and edit each reply, then post it yourself.
Does Reply Monk post to X for me?
No. It never posts, likes or follows on its own. The extension puts a draft in the reply box, and from the web app X opens with your text filled in. You press post.
Does it work on Twitter?
X is the same site, and the extension works on both x.com and twitter.com.
Can it write threads?
Yes. The composer has an X thread builder with a hook and call-to-action score, and a preview of the thread. When you post, X opens with the first post filled in.
Do I need the browser extension?
No. Reply Studio and the composer in the web app work without it. The extension adds the reply bar inside X. It runs in Chrome, Edge, Brave and other Chromium browsers.
What does it cost?
The free plan includes 20 replies or posts a month with no card needed. A reply in the extension costs 1 credit, and three variants cost 3. See pricing.
