Good morning. It’s まさきん.
I knew the Rakuten Link app from Rakuten Mobile had an AI assistant called “Rakuten AI” built in. What I did not know was that it can now summarize your phone calls too.
Let me take a look.
An “AI Call Summary” button now appears on the call screen
Apparently there is now a new “AI Call Summary” button on the in-call screen.
When you tap it, the AI analyzes what was said on the call and writes up a summary. If the call was something like confirming a hospital appointment, it will reportedly also show suggestions related to the conversation.
- An “AI Call Summary” button appears on the call screen
- Tap it and the AI summarizes the call right then and there
- You can also view a list of past summaries from the Calls tab
- No extra charge to use it

There are device requirements
It sounds handy, but not every device is supported.
Supported devices are Android 10 or later and iPhone 16 or later. It is a good idea to check ahead of time whether your phone meets these requirements.
It looks like the feature assumes a fairly recent device. If you are using an older phone, the feature may not show up at all.
Rakuten AI itself has also been quietly improving
The call summary feature appears to be part of “Rakuten AI,” the AI assistant built into Rakuten Link.
Rakuten AI itself launched on both iOS and Android in 2025. It works in a chat format and can answer questions, summarize or translate text, and search for information. Call summaries are a new addition on top of that.
Summary
Rakuten Link’s “AI Call Summary” feature is free to use with no extra charge, as long as you have a supported device.
If you often want to look back at what was said on a call, it could save you the trouble of taking notes. A good first step is to check whether your phone is supported.
Features and supported devices may change in the future. Before you use it, I recommend checking the official website for the latest information.
