Gemini Notebook free tier: quotas, limits and gotchas
Gemini Notebook Free Tier

How Amo and Pimi look
Generous as it is, the paid plan names are shared with Gemini — AI Plus/Pro/Ultra makes it unclear whether you're buying Gemini or NotebookLM, and I have to call out this naming confusion. Also, Ultra was split from US$249.99 into two tiers, and the official site doesn't explain the migration details — I'm still keeping a note on that one.
The naming really is easy to confuse, I'll admit that. But Chinese support is full, and even if you want to upgrade, AI Plus at US$4.99/month with 400GB storage is one of the cheapest paid entry points on the whole site — not expensive at all — and Google ecosystem integration with Drive and Docs is seamless.
So, do you need to pay or not?
Students, researchers, and data organizers: the free version is sufficient, no need to think twice. Only consider AI Plus for US$4.99 if you need a higher quota. However, don't subscribe to Ultra just for NotebookLM; first confirm that you really need Gemini's other features.

Watch out for this
免費版額度其實很夠一般人用（100本筆記、每本50個來源），大部分人根本用不完——不用急著付費；但要注意資訊圖與簡報輸出的浮水印，官方用量表 Watermark Removal 一列免費/Plus/Pro 皆為 No，只有 Ultra 檔才能去除
When the free quota is insufficient, how much does it cost to pay for it?
| Plan | pricing | Description |
|---|---|---|
| Google AI Plus | US$4.99 / mo | 含NotebookLM更高額度(400GB儲存空間)，新增之最低階付費方案；2026-07-30更正：先前note誤植為「2TB」，2TB其實是one.google.com/about/plans另一同名US$9.99 SKU的容量，與此欄US$4.99/gemini.google版本(400GB)非同一方案，見下方notes欄雙SKU並存說明 |
| Google AI Pro | US$19.99 / mo | 含NotebookLM更高額度(5TB儲存空間)；原資料標示US$20，官網現為US$19.99 |
| Google AI Ultra 5x | US$99.99 / mo | 由US$249.99修正為兩檔式結構(官網gemini.google/subscriptions直接確認)；含NotebookLM最高額度(20TB儲存空間)，較Pro 5倍用量 |
| Google AI Ultra 20x | US$199.99 / mo | 由單一US$249.99修正為兩檔式結構(官網gemini.google/subscriptions直接確認)；含 Gemini Notebook 最高額度；Ultra 分 20TB 與 30TB 兩檔，US$199.99 對應 30TB 檔（官方用量表分列 Ultra 20TB Plan / Ultra 30TB Plan），較Pro 20倍用量；one.google.com/about/plans頁面未列出此方案 |
