Where it works
Nine sites, one reply bar
Here is what it does on each one today.
| Site | What it does | Status |
|---|---|---|
| Social | ||
| Comment replies Comments only. Starts in LinkedIn-safe mode: nothing appears on LinkedIn until you switch it on. | Comments only | |
| X | Replies and the new-post box; save posts to your swipe file | Live |
| Comment replies on new and old Reddit; save posts | Live | |
| Replies to posts and comments | Live | |
| Comment replies | Live | |
| Gmail | Compose and “Reply with AI” inside a thread | Live |
| Outlook | AI bar in the compose window | Live |
| Yahoo Mail | AI bar in the compose window | Live |
| Zoho Mail | AI bar in the compose window | Live |
On LinkedIn it helps with comments only. Direct messages and in-feed post drafting are not part of it.
Works in Chrome, Edge, Brave and other Chromium browsers. Firefox and Safari aren’t available yet.
Network by network, the guides for LinkedIn, X and Reddit show what it does on each. See how founders, recruiters and consultants use Reply Monk.
Say what you mean
Pick the intent, then fine-tune the reply
Start from what the reply should do. Then shape it with the controls, which are remembered separately for each site.
- Five intents: Add an insight, Ask a question, Agree and add, Disagree politely, Congratulate
- Choose a persona and a length: short, medium or long
- Reply in 8 languages: English, Spanish, French, German, Portuguese, Hindi, Arabic, Japanese
- Set how many emoji you want, from none to lots, and turn hashtags on or off
- Add a one-off instruction of up to 300 characters
- Add an insight
- Ask a question
- Agree and add
- Disagree politely
- Congratulate
Privacy and control
Privacy switches that start off
You decide what the extension remembers. Here is exactly what it does by default.
- Off by default: log my engagement, store my edited text, include email addresses
- On by default: diagnostics (selector-break reports, a daily check-in, anonymous errors). You can switch them off in the popup
- Email addresses are removed from webmail before text goes to the AI, unless you turn that on
- A one-time notice names the AI providers before you first use it on webmail
- LinkedIn-safe mode is the default for new installs
LinkedIn is opt-in, on purpose
LinkedIn restricts third-party tools. Reply Monk treats that as a real risk and doesn’t hide it.
-
Safe mode by default
On a new install, nothing is added to LinkedIn pages until you switch it on and read a short risk note.
-
Comments only, a soft cap
On LinkedIn the extension drafts comment replies, with a soft cap of 40 a day per device. You review and post each one.
-
A remote off switch
Any site, LinkedIn included, can be switched off remotely in about ten minutes without a store update.
Safe mode lowers the risk. It doesn’t remove it, and LinkedIn does not endorse the extension.
The details
Small touches that save you time
-
Regenerate or get 3 variants
Not quite right? Regenerate for another go, or ask for three variants at once to pick from.
-
Undo after insert
If you insert a reply and change your mind, one click puts the box back as it was.
-
Streams as it writes
The reply appears word by word, so you can start reading straight away.
-
A voice chip that tells the truth
It shows whether your learned voice is being used, such as “Voice v3, 12 samples”, or that replies are generic.
-
“n left” and a friendly limit card
A counter shows credits left after each reply. When they run out you get a clear card with your usage and when it resets, with a link to see plans.
-
A short first-use tour
A quick tour appears once per site on each device, then stays out of the way.
-
Save to your swipe file
A bookmark button on LinkedIn, X and Reddit saves a post to your library. Right-click selected text to save it too.
-
“Draft a post about this”
On X and Reddit, turn a post you are reading into a draft in the web composer.
- Optional
Preview before insert
Prefer to read it first? Switch on a preview step. It is off by default.
-
Minimal permissions
The extension asks only for storage, a right-click menu and alarms, and only runs on the exact sites listed above.

Questions
The browser extension, answered
Does the extension post for me?
No. It writes a reply in the box and you read it, edit it and press the site’s own post button. It never likes, follows, connects or posts on its own.
Which browsers does it work in?
Chrome, Edge, Brave and other Chromium browsers. Firefox and Safari aren’t available yet.
Is it safe to use on LinkedIn?
LinkedIn restricts third-party tools, and Reply Monk can’t promise how LinkedIn will treat any account. That’s why the extension starts in LinkedIn-safe mode: nothing is added to LinkedIn until you switch it on and read a short risk note. On LinkedIn it only helps with comments, and a soft cap of 40 replies a day per device applies. If you would rather not use it there, Reply Studio works without touching the page.
What does it collect?
Three privacy switches are off by default: logging your engagement, storing your edited text and including email addresses. Email addresses are removed from webmail before it goes to the AI unless you turn that on. Diagnostics, meaning selector-break reports, a daily check-in and anonymous errors, are on by default and you can switch them off in the popup.
How many credits does a reply cost?
One credit for a reply, and three for three variants. The cost is shown on the button before you click. The free plan includes 20 replies or posts a month. See pricing.
What if a site changes and something breaks?
Each site can be switched off remotely in about ten minutes without waiting for a store update. Updates to how the extension finds buttons on a page are signed so they can’t be tampered with on the way.
