How it works
A shortcut, a few words, Return.
That is all.
No window to switch to, no prompt to write, no copy and paste. ReplyFive sits in the menu bar and works inside the app you are already in.
Press the shortcut in the reply box
Leave the cursor in the field you want to reply from and press the shortcut. ReplyFive reads that conversation and opens its panel in front. The app you were in stays active.
Could you do 10% off next week's order?
Type the gist
"No discount. Can ship a week earlier instead." That is enough. Formality and layout follow the person and the app automatically.
Press Return
The finished reply is written into the field you were in. Read it and send. ⌥Return opens it for review first, esc closes without a trace.
Per person
Same few words. Different reply for each person.
Matched to the other person's language, the app and the thread so far. A full email with greeting and sign-off for a client, a polite note for your manager, a concise line for a teammate, Japanese for a contact in Japan.
To a clientGmailTo your managerTeamsTo a teammateSlackTo a contact in JapanLINE · JapaneseFeatures
Only what a reply needs, right in the panel.
Who you are writing to, the language and the level of formality are read from the conversation. Set things up once; after that you only type a few words.
-
Reads the thread, knows who you're writing to
It reads the conversation area of the app in front and addresses the reply to the sender of the latest message. Click the name in the panel to see what was read.
-
Continues the conversation
With consent, settings and organization policy allowing it, recent messages stay encrypted on your device to help continue the conversation. You can stop collection and separately delete saved records in Settings.
-
The other person's language
The reply comes back in the language of the conversation in front of you. Japanese thread, Japanese reply. You can also pin a language in Settings.
-
Learns how you write
With consent, settings and organization policy allowing it, inserted replies and edits are kept encrypted on your device as examples for later replies. Turning records off does not delete them; use the separate delete control in Settings.
-
Meaning checked before insertion
Every fact and decision you typed is kept, and the reply is addressed to the right person, before it goes in. If your words can be read two ways, both versions are offered.
-
Flags what you forgot to answer
If the other person is waiting for a yes or no, an answer, a date or a deliverable and your words don't cover it, the panel says so before inserting. Add a few words and it's in the reply.
-
Review, rewrite, copy
⌥Return shows the reply for editing before it is inserted. Not quite right? Rewrite. Apps that do not accept direct insertion get a copy to paste.
-
Reads the screen when it has to
With consent and OS permissions, supported apps can read text from the conversation area when it changes or you press the shortcut. Captured images are not saved as record files.
Also: change the shortcut, set your name, pin the reply language, always review before inserting, launch at login. A draft written on your Mac appears the moment you stop typing, and stays if the network drops.
Teams
The whole team replies right away.
Sales, customer support, general affairs, accounting, HR, PR. Whatever the department, someone is waiting for a reply. When each person can answer in five seconds, conversations inside and outside the company stop stalling and more exchanges fit into a day.
An illustration: six departments of one company, six enquiries arriving at once.
Customers never wait
A finished, properly formal reply goes out the moment the enquiry arrives. Nothing piles up in "I'll write that later", so fewer messages get missed.
More exchanges, faster decisions
Fast replies bring fast answers back. Several exchanges fit into one day, so quotes and schedules get settled the same day.
Invite once, everyone has it
On the Team plan, invite colleagues from the admin console and it works on each person's Mac. The price stays the same however many people join, and the team shares 100 replies a day.

Enterprise
Contact us
Runs entirely inside your own environment. Company-wide rollouts.
For companies whose text cannot leave the building, we help you run ReplyFive on AWS, Google Cloud, Azure or another cloud you specify, or on a local LLM on your own servers. Conversation text and generated replies never leave your environment.
- Runs entirely on AWS, Google Cloud, Azure or the environment you specify
- Local LLM on your own servers also supported
- Annual term
- We support you from setup through operation
All prices exclude consumption tax, which is added to every charge. Lite, Pro and Ultra are for one person (one device); Team is one flat price regardless of headcount, and the daily allowance is shared across the organization. Every plan has a daily allowance, and the count resets at 9:00 Japan time (0:00 UTC). Change or cancel your plan from the admin console.
Ultra is billed monthly only. Replies beyond the 100 included each day are ¥3 each, counted through the month and added to the next invoice.
Payment is by credit card through Stripe only.
FAQ
The things people ask before they install it.
Which apps does it work in?
Every messaging and mail app on your Mac: Slack, Microsoft Teams, Gmail, Outlook, Mail, LINE, LINE WORKS, Chatwork, Google Chat, Messenger, WhatsApp, Instagram, X, Discord, Telegram, Zoom and any other app with a text field. In most apps the reply is written straight into the field you were in.
A few apps do not accept direct insertion. There ReplyFive copies the reply for you to paste and tells you so.
Is it really five seconds?
Five seconds is the typical time from pressing the shortcut, typing a few words, to the reply appearing in your field. A draft written on your Mac appears the moment you stop typing, then the finished reply replaces it. Long replies or a slow connection can take a few seconds more.
Does it ever send a message on my behalf?
No. ReplyFive stops at writing the reply into your field. Whether to send is always your decision, and there is no setting that changes this. It never leaves drafts in your mail or chat either.
Can my team or company use it?
Yes. On the Team plan you invite colleagues from the admin console, and everyone is covered by one flat price with no limit on headcount. The organization shares 100 replies a day, and an administrator can add another 100 a day for ¥1,980 a month at any time. For company-wide rollouts, or if text cannot leave your company (running entirely on AWS, Google Cloud, Azure or another cloud you specify, or on a local LLM on your own servers), ask about the Enterprise plan by email.
Can I use it without any text leaving my company?
Yes, on the Enterprise plan. The current self-hosted ReplyFive server sends text to the configured Groq or Amazon Bedrock provider. Requirements prohibiting external or international transfer need verification of the provider, region and inference destination, and may require a separately agreed configuration. We support you from setup through operation. Email us.
Which languages does it write in?
All of them. The reply comes back in the language of the conversation in front of you: a Japanese thread gets Japanese, a German thread gets German. There is no language to select, and nothing to change when you switch during the day.
Why does it need the Accessibility permission?
After consent, these permissions allow reading the foreground conversation and inserting a reply. With conversation records enabled, foreground or conversation changes also trigger capture. macOS uses Accessibility; Windows/Linux use their supported OS facilities and permissions. Withdrawing consent stops capture. Captured images are not saved as record files.
Which operating systems are supported?
Mac (macOS 13 or later, Apple silicon and Intel), Windows (Windows 10 or later) and Linux.
What happens when I reach the daily allowance?
The panel tells you, and the draft written on your Mac stays on screen, so you can send that or finish it yourself. The count resets at 9:00 Japan time (0:00 UTC), and the panel shows you when. On Lite and Pro you can move up a plan from the admin console at any time; on Team an administrator can add another 100 replies a day. The trial allows 200 replies a day.
What if I need more than the 100 a day on Ultra?
Ultra keeps writing. Every reply past the first 100 in a day costs ¥3, counted through the month and added to your next invoice by Stripe, so nothing stops in the middle of a conversation. The admin console shows how many replies you have used.
How do I cancel?
Any time, from the admin console. Monthly and yearly plans renew automatically; cancellation takes effect at the end of the current term, and the remaining period is not refunded. The 14-day trial needs no credit card and simply ends if you do nothing.
