Notion AI 料金 (2026)

Notion を週10時間以上利用している場合は、ワークスペースに基づく検索とインライン AI ライティングだけでコストを正当化できます。Notion の利用頻度が低い場合や ChatGPT Plus をすでに契約している場合は、価値を見出しにくいかもしれません。多くのナレッジワーカーは両方を併用しています（合計月額 $30）。

Notion AI starts at $10/month for the Add-on tier (notion ユーザー). There is also 1 other tier — see the full table above for the feature breakdown.

Notion AI doesn't currently advertise a self-serve free tier. The cheapest entry is the Add-on tier at $10/mo. Many users start there and downgrade if it doesn't fit their workflow — most plans are month-to-month.

For users who run personal workflows, the Add-on tier usually pays for itself within the first month. If you only run occasional one-off tasks, look at a cheaper alternative or the free tier (if available) before committing.

Most SaaS vendors in this category — and Notion AI typically follows the pattern — offer 10–20% off when you pay annually instead of monthly. Check the checkout page for the exact discount; the annual toggle is usually under the pricing tiers on the vendor site.
