Spend less time on customer email. Send better answers.
ReplyPen drafts your replies in Gmail and Outlook. For every email it checks your help pages and the answers you have already given, shows you what it checked, and learns every day.
We're opening to new teams soon. We'll email you when your spot is ready.
Hi Sarah,
Yes, you can. Orders can be changed until they are packed, which usually happens the morning after you order. Reply with the new address and we'll update order 4821 today.
If it has already been packed, we can redirect it with the carrier for free. It just takes one extra day.
Best, Tom

How it works
Set up in one sitting.
No migration and no new inbox. Connect what you already have, and ReplyPen drafts its first reply within minutes.
-
Inbox Step 1
Connect your inbox
Sign up with Google, Microsoft or email, then connect Gmail or Outlook. A shared address like support@ works too.
-
Memory Step 2
Tell about your business
Add your website and tell about your business. Your memory will continue to learn about you as you continue to use ReplyPen.
-
Data sources Step 3
Connect your sources
Provide the link of your help center and add other data sources such as your CRM, codebase or other files.
Check note
Every Draft shows what it checked.
Under each Draft, a short Check note lists the help articles, website pages and past emails it relied on. You can see in seconds where an answer came from, without rereading your help center to be sure.
A careful colleague would tell you where an answer came from. ReplyPen does the same.
How the Check note works →Works where you already are
Your inbox stays your inbox.
ReplyPen is not a helpdesk, not a new inbox and not a chatbot. It works inside the email you already use.
Drafts where you expect them
Each Draft appears as a normal draft in Gmail or Outlook, on your laptop and on your phone. Send it like any other email.
A web app when you want one
The ReplyPen web app lists every email it has handled. Review, send, give Feedback or regenerate in one place.
Only the email that needs a reply
Newsletters, notifications, receipts, auto-replies, internal mail and spam are skipped automatically, so your Drafts folder only holds replies you need.
Memory
It learns, and shows you what it learned.
Every edit you make teaches ReplyPen something. What it knows about your business and your voice is written down in Memory, where you can read it and correct it.
Learn more about Memory →- Business profileWhat you sell, who you serve, and the facts every reply should get right.
- Tone profileHow you greet, how long you write, how you sign off.
- Knowledge logA running record of what ReplyPen learned from your edits and Feedback, and when.
Data sources
Grounded in what you already wrote.
Start with the sources every business has. Add more when you want deeper answers.
Help center
Connected during setup. Works with Zendesk, Intercom, Help Scout and Freshdesk help centers.
Website and past emails
Your product, shipping, pricing and policy pages, plus the replies you've already sent. You can add files too.
Deeper, when you need it
Software companies can connect their code base, so Drafts can explain how the product actually behaves. Connect other tools when you're ready:
- Slack
- Notion
- Stripe
- Google Workspace
- GitHub
- Shopify
- HubSpot

Rules and Reports
You decide how much it does.
ReplyPen starts in draft-only mode. Nothing reaches a customer until you press send.
Auto-send, for the kinds of email you choose with a Rule, is coming in a later version. It will be off until you switch it on.
Rules
- Skip emails by sender, domain, subject or body text.
- Always draft for the senders and topics that matter most.
- Auto-send is coming in a later version, off until you switch it on.
Reports
Time saved, Drafts created, Drafts sent unchanged or edited, and the share of your incoming email that got a Draft, week by week.

Isn't this already free in Gmail?
Gmail and Outlook can turn a prompt into a polite email, and Gmail can suggest a reply when you open a message, with details like a booking code from your other emails and Drive files. They are built around your own inbox, not around your help center and website, and Gemini in Gmail is not available to people who work in a shared mailbox as a delegate.
ReplyPen writes a Draft for every customer email before you open it, checks it against your help pages, website and past replies, and writes down each correction so the next Draft gets it right.
ReplyPen writes the answer, not just the wording. You keep Gmail, and ReplyPen fills it in.
| Gmail / Outlook AI |  ReplyPen | |
|---|---|---|
| Who starts the reply | You, with a prompt, or Gmail suggests a reply when you open the email | ReplyPen, before you open the email |
| Where the facts come from | The thread, and in Gmail details from your other emails and Drive files | Your help center, website and past replies, for every email |
| Can you see what it used | Gmail lists the emails and files under Sources | A Check note under every Draft, including help pages |
| Your correction | In Gmail, standing instructions you give Gemini carry over | What it learns from your edits is written down in Memory |
FAQ
Questions
Will ReplyPen send emails without me?
No. ReplyPen writes Drafts, and you read and send them. Auto-send for emails you choose with a Rule is coming in a later version, and it will be off until you switch it on.
Do I have to change how I work?
No. Drafts appear in Gmail or Outlook as normal drafts, including on your phone. The web app is there when you want to review several at once, give Feedback or change Rules.
Which emails get a Draft?
Customer emails that need a reply. Newsletters, notifications, receipts, auto-replies, internal mail and spam are skipped. You can add Rules to skip or always draft for certain senders, domains, subjects or body text.
What does ReplyPen use to write a Draft?
Your help center, your website and the replies you've already sent, plus any files or tools you connect. The Check note under each Draft lists what it checked for that reply.
What if the answer isn't in any of those?
Edit the Draft and send it as you normally would. ReplyPen learns from the change and adds it to the Knowledge log, so the next similar email goes better.
Which languages does it write in?
Drafts are written in the language your customer wrote in.
Can my team use it?
Today ReplyPen works with one mailbox and one voice. A shared address like support@ is fine. Inviting teammates is coming.
Do you store my emails?
We keep copies of the messages we handle so we can follow each conversation. They're stored in Frankfurt, and our AI providers are not allowed to train on them. Where your data goes →
What happens after the free week?
Add a card to keep going and pay for what you use. If you don't add one, you're not charged.
