Complete four short sections. Get an instant recommendation for Standard, Plus, Pro or Ultra—plus the reason not to over-upgrade, your estimated capacity risk, and the next AI-routing move.
Start with Standard if its quotas fit your work. For a single notebook, 51–100 sources require Plus, 101–300 Pro, 301–500 Ultra 20 TB, and 501–600 Ultra 30 TB. No current consumer tier supports more than 600 sources per notebook. High usage by itself is not a reason to upgrade: recurring limit friction, Deep Research quotas, and real notebook capacity should drive the decision.
Updated September 6, 2026 · Consumer-plan facts checked against Google support and Google One. Formerly NotebookLM; the same tool and account limits apply.
Why trust this tool? It recommends the lowest adequate tier and has no affiliate relationship with Google. Hard capacity limits come from Google; the conservative recommendation rules and routing advice are independent NotebookLM Guide editorial frameworks.
Gemini Notebook moved to compute-based AI usage: prompt complexity, model, feature use and conversation length affect consumption. Usage generally refreshes every five hours until the weekly limit is reached.
AI Plus now has a $4.99/month 400 GB entry option, while Google One also lists a $9.99/month 2 TB AI Plus variant in the U.S. AI Pro remains $19.99/month with 5 TB. Google’s I/O announcement lists Ultra at $100 or $200/month.
Hard capacity comes first. Actual limit friction comes second. Studio variety alone does not justify an upgrade.
Gemini Notebook combines hard notebook/source ceilings with feature quotas and compute-based usage. Price is included because a plan decision is incomplete without the cost of the extra capacity.
| Plan | Current US price | Notebooks | Sources / notebook | Chats / day | Audio / video | Deep Research | Relative AI usage |
|---|---|---|---|---|---|---|---|
| Standard | Free | 100 | 50 | 50 | 3 / 3 per day | 10 / month | Standard |
| Plus | $4.99/mo · 400 GB* / $9.99/mo · 2 TB* | 200 | 100 | 200 | 6 / 6 per day | 3 / day | 2× Standard |
| Pro | $19.99/mo · 5 TB | 500 | 300 | 500 | 20 / 20 per day | 20 / day | 4× Standard |
| Ultra | $100 or $200/mo | 500 | 500–600 | 2,500–5,000 | 100–200 / day | 75–200 / day | 5× or 20× Pro† |
* AI Plus currently has two U.S. storage/price variants: $4.99/month with 400 GB and $9.99/month with 2 TB. Both are AI Plus tiers for Gemini Notebook capacity; choose based on storage needs, not a higher Notebook limit. † Google states Ultra relative to Pro, while Plus and Pro are stated relative to Standard; the bases are labeled explicitly.
The next problem is routing grounded research, drafting, coding, verification and fallback work across the AI tools you already pay for without duplicating work or losing project state.
Start with the lowest tier that fits your hard capacity. Standard supports 50 sources per notebook, Plus 100, Pro 300, and Ultra 500 or 600 depending on the Ultra tier. High usage alone is not a reason to upgrade unless limits are actually interrupting valuable work.
No. The tool runs in your browser and gives the recommendation immediately without requiring an email address or account.
No. Gemini Notebook uses compute-based limits that depend on prompt complexity, models, features and conversation length. The tool estimates plan fit from published capacity limits and the usage pattern you provide.
The recommendation is calculated in your browser. The site records aggregate tool events such as starts, completions and recommendation categories, but the picker does not ask for personal information.
The tool recommends a tier from source count, notebook count, Deep Research volume and reported limit friction. It does not measure the daily quantity of every Studio output; verify those quotas in the table before purchasing. Product facts were rechecked September 5, 2026; prices and quotas can change.
