Your personal AI communication assistant
Drafts your Gmail and Google Chat replies, and any message you paste in from another app. Follow-up on Gmail and Google Chat stays within limits you set.
Order the standing desk
Order it if it’s under $500 and can arrive this month. Ask me before paying more or waiting longer.
The desk is $420 and arrives on the 12th, which is within your rules, so I confirmed the order.

Give the assistant guidance, ask for a draft, or tell it to continue…
PromptMail is in beta. Join the waitlist and we’ll email you when your invite is ready.
Reply to inbox email
Search your Gmail inbox, pick a message, and tell the assistant what to do: summarize it, draft a reply, or handle the whole thread.
Start a new email
Give the assistant a recipient and a goal, such as an inquiry, a negotiation, or a scheduling request, and it drafts the first message for you.
Reply in Google Chat
Pick a Google Chat space and let the assistant answer questions or keep a conversation moving, right inside the space.
Use any messaging app
Paste a message from any app and copy the draft back yourself. PromptMail never sends it for you.
Automatic follow-up
Handle the back-and-forth until it’s settled
Set the outcome, the acceptable options, a reply limit, and an end date. PromptMail handles the replies, and asks you if one falls outside those rules.
You can turn automatic follow-up off at any time.
Your goal
Handle replies using Tuesday or Thursday afternoon until we confirm a meeting time. Ask me before agreeing to anything else.
Incoming reply
Thursday at 3pm works for me. See you then?
PromptMail replies within your rules
Thursday at 3pm is confirmed. Looking forward to it.
Multilingual communication
Reply in your recipient’s language
Read and discuss a message in your preferred language, then let PromptMail draft the reply in the language used by the sender—across Gmail, Google Chat, and messages you paste in.
You review and approve every draft before it is sent.
Message received in Chinese
原定的海景双人房没有了，酒店改成了临街的标准间，楼层也从 8 楼换到 2 楼，价格不变。你看这样可以吗？如果要改，需要今天确认。
Ask PromptMail in English
Explain this and draft a reply asking for more details about the room change.
Chinese reply ready to review
谢谢告知。同意之前，想再确认新房间是一张大床还是两张单人床，是否含早餐，以及临街会不会比较吵。如果不同意这次更换，还有其他房型可以选择吗？
How it works
You stay in control at every step. Nothing is sent until you approve it or explicitly authorize an agent to follow up.
-
1
Delegate a conversation
Choose an inbox email, a new recipient, a Google Chat space, or Manual and paste a message from any other app.
-
2
Chat with the assistant
Ask questions about the thread, request a draft, and refine it. When it looks right, approve and send it from the conversation.
-
3
Authorize autonomous follow-up
Set a goal, guardrails, a maximum number of replies, and an expiry. An agent watches for new replies and answers within that scope, or escalates to you.
-
4
Review the audit trail
Every draft, send, escalation, and authorization change is recorded in the conversation timeline. Revoke authorization at any time.
Scoped authorization
Autonomous replies stay on the same thread or space, stop at your send limit, and expire when you say so. Choose "always escalate to me" to keep approving every send.
Your rules, in AGENT.md
Write standing instructions that apply to every autonomous conversation, while send limits stay per conversation. When a rule or guardrail would be crossed, an agent escalates instead of replying.
Secure & private
Sign in with Google OAuth 2.0. Gmail and Google Chat access is requested separately, only when you turn on each feature, and can be revoked at any time.
