About this extension
Write the reply, don't stare at it.
AI Reply Writer puts one button in the message box of the apps you already work in. Click it, and it reads the conversation that is on your screen and drafts a reply in your own tone. You edit it, and you send it. Nothing is ever sent for you.
It works where you already write — in your inbox, your team chat, your DMs and the comment box under a post — instead of one more tab to paste into and paste back out of.
HOW IT WORKS
WHERE IT WORKS
Email and team chat, direct messages, social posts and comments, and review replies — 22 sites in all, including Gmail, WhatsApp and LinkedIn. Open a conversation on any of them and the button is already there in the message box, and it is the same button and the same panel every time.
The full list of supported sites is on aireplywriter.com.
WHY THE DRAFTS ARE WORTH SENDING
It reads the whole thread, not just the last line. It works out what has already been agreed, answered or sent, and writes the next step instead of repeating a settled point.
It replies to the message you picked. Press reply on one message in a busy group and you get a reply to that one — not to the forty other conversations happening in the same room.
It can see what was sent. Photos, screenshots, documents and voice notes are read, so a reply to a picture is about the picture and a reply to a voice note answers what was said in it.
It checks itself before you see it. A separate pass looks for anything risky — a promise you did not make, a price you did not quote, a date that has already passed — and rewrites it.
Grammar is fixed automatically. Every draft is corrected on the way out, so what lands in the box is the version you would have written on a good day.
MAKE IT SOUND LIKE YOU
• Six tones — Professional, Friendly, Casual, Straightforward, Formal, Enthusiastic
• Three lengths — short, medium or long
• Save your own writing styles and reuse them
• Fill in "About You" and "About Your Business" once, and every reply knows who is writing
• Set a reply persona and a niche, so a reply from a business does not read like a reply from a stranger
• Set your own gender and the recipient's, which matters in every language that inflects for it
• It learns from your edits. Change a draft before you send it and the next one needs less changing.
TELL IT WHAT TO SAY
• Type an instruction — "politely decline", "ask for the invoice", "agree but push the date" — or leave it blank for an automatic reply
• Save the instructions you use often as prompt templates
• Regenerate for a different take, or shorten what you have
• Drop in an emoji from the picker
• Writing a post? Type a topic and get five angles to choose from, or skip them and write straight from what you typed
WORKS IN YOUR LANGUAGE
Replies match the language of the conversation automatically, or pick one from 76 — including Roman Urdu and Hindi, which most tools romanise into something nobody would send.
CHOOSE THE AI THAT WRITES
Thirteen models from Google, Anthropic, Meta and OpenAI, switchable per reply. Fast ones for a quick acknowledgement, stronger ones for a message that matters. The picker is in the panel; nothing to configure.
ANSWER WITH YOUR OWN FACTS
Add your prices, policies, opening hours, service area and FAQs once. Replies use them instead of inventing something plausible — the failure that makes AI replies embarrassing rather than useful. Attach a document and it is read the same way.
YOU ARE ALWAYS THE ONE WHO SENDS
Every draft lands in an editable box. Regenerate it, shorten it, rewrite it, or throw it away. The extension never sends, posts or comments on your behalf, and it does nothing at all until you click the button.
PRIVACY
• It runs only on the supported sites, and does nothing on any other page you visit
• No access to your Google account — no OAuth scopes, no Gmail API. Gmail is read through the page you already have open, like any other site
• The text sent for drafting is not kept in our database after your reply comes back, is never sold, and is never used to train AI models
• Everything held in your account can be viewed and deleted by you, whenever you want
FREE TO START
A free allowance every month, with no card required. Paid plans add higher limits and more capable models. Cancel from your account page.
WHO IT IS FOR
Anyone whose inbox is the job: freelancers answering clients, small businesses answering reviews and enquiries, support and sales teams, recruiters, creators answering comments, and anyone who writes all day in a second language.
THERE IS AN ONLINE VERSION TOO
Prefer working in a tab? aireplywriter.com does the same job in the browser — the same account, the same free allowance.
