Every reply drafted before you open your inbox.
CometReplyAI is an AI-powered productivity tool for email and messaging. Securely connect Gmail, Google Calendar, and Google Tasks — plus Outlook, Slack, WhatsApp, Instagram, LinkedIn and 30+ more apps — and it reads your incoming messages to draft ready-to-send replies in your own writing style, turn requests into calendar events, and capture action items as prioritized to-dos. Your data is used only to power these features — never to train AI models, and never sold.
A productivity tool that unifies your inbox and generates AI replies for Gmail and every messaging app — draft email replies in seconds, automate your calendar and to-dos, and stay on top of every conversation.

Everything Comet does for you
Drafts in your voice, every inbox in one place, and the busywork — scheduling, follow-ups, cleanup — handled automatically.
Replies that sound like you
Comet learns how you actually write — your tone, phrasing, and sign-off — so drafts read like you wrote them, not a robot.
One inbox for everything
Email (Gmail, Outlook, Apple Mail, Yahoo) and chat (Slack, Teams, Discord, Telegram, WhatsApp) — all in one place. Stop jumping between apps.
Scheduling on autopilot
Comet reads your calendar and proposes meeting times that don't clash — and pulls invites straight out of your messages. Connects Google, Outlook, Apple, Calendly & Cal.com.
Never drop a follow-up
Comet surfaces the replies you owe and syncs with your task apps — Todoist, Asana, Trello, ClickUp, Linear, Notion & more.
A cleaner inbox, automatically
Smart suggestions to unsubscribe, archive, or mute the noise — so what's left is what actually matters.
Works with your existing inbox
Two-way sync means your changes flow right back to Gmail and Outlook. No new inbox to learn.
See the hours you save
A live counter shows exactly how much time Comet has given back to you this week and month.
Private and secure
Every account you connect stays locked down — connections are encrypted and isolated to you, and your data is only ever used to draft your replies. Never sold, and never used to train AI models.
Security & Privacy
Your inbox is private. We're built to keep it that way.
CometReplyAI handles your most sensitive conversations, so security isn't an afterthought — it's how the product is built.
We never see your password
You connect securely through Google or Microsoft — your login stays with them, and that password is never sent to us.
Bank-grade AES-256 encryption
The credentials that connect your inboxes are encrypted with AES-256, and your data is encrypted at rest. Every request runs over HTTPS.
Your data is yours
It's only ever used to draft and organize your replies — never sold, never shared with advertisers, and never used to train AI models.
Fully isolated, per user
Strict per-user separation is enforced in the database with row-level security — so no one else can ever reach your data.
Built to Google's standards
CometReplyAI follows the Google API Services User Data Policy for how connected account data is accessed and handled.
You're in control
Disconnect any account at any time, or delete your account and everything in it with one click. Immediate, and entirely your call.
Pricing
Plans for every communication load

FAQ
Frequently asked questions
What is CometReplyAI?
CometReplyAI is an AI assistant that connects to your inboxes and drafts ready-to-send replies in your voice across Gmail, Outlook, Slack, and more. It also turns messages into calendar events and prioritized to-dos. You review and approve everything before it sends.
Is CometReplyAI free?
Yes. There is a free plan that includes AI-drafted replies for two connected apps, with no credit card required. Paid plans start at $9.99/month and add higher monthly volume and the Compose assistant.
Which apps does it connect to?
Email (Gmail, Outlook, Yahoo Mail, iCloud Mail), messaging (Slack, Google Chat, Microsoft Teams, Discord, LinkedIn, WhatsApp, Telegram, and more), plus calendar and to-do tools — over 30 integrations in total.
Does it send messages automatically?
No. CometReplyAI drafts replies and you stay in control. Nothing is sent on your behalf until you have read the draft and clicked send.
Is my data private and secure?
Yes. Connections use encrypted token storage, your data is isolated per user with row-level security, message bodies are never written to our logs, and your content is never used to train AI models or sold.
Can it write in my own voice?
Yes. You set your writing preferences and CometReplyAI drafts in that tone. Every draft is editable, and you can ask it to regenerate a different version.
