Notion AI Review — Is It Worth It in Japan?

Notion is already one of the most popular productivity apps in the world. But with Notion AI added on top, it becomes something even more powerful. Is it worth the extra cost? Here’s my honest take from Japan.

The Short Answer

Yes, Notion AI is worth it if you’re already using Notion regularly. It genuinely speeds up your workflow and makes the app significantly more useful. If you’re not using Notion yet, it’s a great reason to start.

What is Notion AI?

Notion AI is an add-on feature built directly into Notion. It uses AI to help you write, summarize, translate, brainstorm, and organize information — all without leaving your workspace.

It’s not a separate app. It lives inside Notion, which makes it incredibly convenient.

Key Features

Write and edit — Generate first drafts, rewrite paragraphs, fix grammar, and adjust tone directly inside your notes.

Summarize — Paste in long documents or meeting notes and get a clean summary in seconds.

Action items — Notion AI can extract action items from meeting notes automatically. This alone saves me significant time.

Translate — Translate content between Japanese, English, and other languages without leaving Notion.

Brainstorm — Ask Notion AI to generate ideas, outlines, or lists on any topic.

Q&A across your workspace — One of the most powerful features: ask Notion AI questions about your own notes and it will find the answer.

Performance in Japan

Notion AI works perfectly in Japan with no restrictions. Japanese language support is solid — you can write prompts in Japanese and get responses in Japanese.

The Q&A feature works well for English content. For Japanese-heavy workspaces, results can be slightly less consistent, but still useful.

Pricing

As of mid-2025, Notion discontinued the standalone $10/month AI add-on. AI features are now bundled into the Business plan ($20/user/month). Free and Plus plans retain only a limited number of trial AI responses.

Pros and Cons

Pros:

• Built directly into Notion — no switching apps
• Saves significant time on summaries and action items
• Works well in Japan
• Useful Japanese language support
• Q&A feature is genuinely powerful
• Integrates with everything already in your workspace

Cons:

• Now requires Business plan ($20/user/mo) — no longer a $10 add-on
• AI quality not quite as strong as Claude or ChatGPT for pure writing
• Japanese Q&A can be inconsistent
• Requires existing Notion habit to get full value

Who Should Use Notion AI?

Notion AI is a great fit if you:

• Already use Notion for notes, projects, or planning
• Take a lot of meeting notes and need summaries
• Want to write and organize in the same place
• Need to translate content regularly
• Want AI built into your existing workflow

How It Compares to Claude and ChatGPT

Notion AI isn’t a replacement for Claude or ChatGPT — it’s a complement. I use all three for different things.

Final Verdict

Notion AI is a genuinely useful tool, especially if you’re already a Notion user. The summarization and action item features alone justify the cost for most people. For bloggers, remote workers, and anyone who manages a lot of information, it’s worth adding.
