About this app

A Main Line Phone System That Doesn't Interrupt Your Work

Leave phone calls to Callnote and focus on your work.

Callnote is a service that automates the initial response to calls to your main line. It automatically receives calls with an automated voice, records them, transcribes them, summarizes them with AI, and sends notifications to chats. It transforms phone calls into something you "read later," like emails or chats.

■ Don't Stop What You're Doing Even When the Phone Rings
Even during meetings or customer service, the automated voice answers and records the call. You can change the response message, recording time, and silent timeout from the app.

■ Read the Call Later
AI transcribes and summarizes the call, displaying key points and recommended actions. You can review the content on your smartphone in your free time. You can also replay the original recording as needed.

■ Calls Arrive in Your Usual Chats
Supports automatic notifications to Slack, email, LINE, and Lark. Receive calls in the tools you normally use and share them with your team. Notification destinations are configured in the web version.

■ Handle only the important calls later
You can identify important calls by filtering call history by category, priority, and whether they are "unconfirmed" or "requires follow-up." Record the status of your responses by switching to confirmed or using internal memos. It also supports managing blocked numbers.

■ Switch organizations and share with your team
You can switch between organizations from Home, Call History, and Settings. You can search by organization name or phone number to view call history and settings for each organization. Member invitations and organization creation are done via the web version.

■ Log in with Google
Google login is supported. You can also use accounts created with your email address and password.

【About Usage】
