ReplyPenWhat does Gemini in Gmail do well?
Gemini in Gmail is part of Gmail itself. It summarises long threads, suggests replies at the bottom of an email, writes or rewrites a message from a prompt, and can pull details from your other emails and Drive files into a draft. It comes with many Google Workspace plans and Google AI plans, works on the web and in the Gmail phone apps, and adds no new company with access to your mail. For someone who wants help with their own inbox, that covers a lot.
What does ReplyPen add for customer email?
ReplyPen starts from a different question: what is the right answer for this customer? It reads your help center, your website and the replies you already sent, and writes a Draft in the customer’s thread before you open it. Under each Draft, a Check note lists the help articles, website pages and past emails it used, so you can check an answer in seconds. When you edit a Draft, ReplyPen notes what changed and keeps it in the Knowledge log, which you can read and correct in Memory.
It is built for the inbox customers write to: a shared address like support@ works, Outlook works, and newsletters, receipts and notifications are skipped. Nothing is sent unless you send it.
When is Gemini in Gmail enough?
If you answer a handful of customer emails a week, the answers are in your head or your own inbox, and you already pay for a Google plan that includes Gemini, start there. ReplyPen earns its place when customer email is a daily job, the answers live in a help center or on your website, or several people work from one address.
Can you use both?
Yes. ReplyPen adds normal drafts to your Gmail threads and changes nothing else, so Gemini in Gmail keeps working next to it. See how ReplyPen shows what a Draft used or pricing.
