For free studying, NotebookLM is still hard to beat. --- If you want a NotebookLM alternative for long PDFs, what matters most is how much work it takes to get back to the page behind each answer. NotebookLM, renamed Gemini Notebook in July 2026, cites the exact quote and jumps to it, but its help pages never mention page numbers. BrainBox, ChatPDF and Humata take you to the cited passage in the file, and BrainBox also gives you the page. Claude and ChatGPT read long PDFs, though their official pages don't describe page-level citations. For free studying, NotebookLM is still the benchmark. > **Worth remembering** > > With a 300-page contract, case file or thesis, the citation that helps is the one that lets you check the sentence in the original without hunting for it. ## What changed in NotebookLM in 2026? On July 16, 2026, Google [renamed NotebookLM to Gemini Notebook](https://blog.google/innovation-and-ai/products/gemini-notebook/notebooklm-gemini-notebook/). It is still a standalone product, notebooks sync with the Gemini app, and each notebook now gets code execution for data analysis, first on AI Ultra and then on Pro. We use both names here because most people still search for NotebookLM. Current limits, from the [plans page](https://support.google.com/notebooklm/answer/16213268): 100 notebooks with 50 sources each on the free plan, 300 sources on Google AI Pro and up to 600 on AI Ultra. Each source can hold up to 500,000 words or 200 MB, and there is no page limit per source, according to the [FAQ](https://support.google.com/notebooklm/answer/16269187). ## How do the alternatives handle long documents? | Tool | Free plan | How it cites | Limits for long documents | Where it wins | |---|---|---|---|---| | NotebookLM / Gemini Notebook | 100 notebooks of 50 sources | Exact quote; selecting it jumps to the passage. Help pages don't mention page numbers | 500,000 words or 200 MB per source | Free plan, Audio and Video Overviews | | BrainBox | 100 intelligence units and 500 MB | Document and page; opens the file on that page with the passage highlighted | 2 GB per file, 50+ formats, audio and video up to 10 hours | Exact page, 30+ models, team roles | | ChatPDF | 2 documents a day | Clickable citations that scroll to the exact source in the PDF | No limits listed on the homepage | A single PDF, no account needed | | Humata | 60 pages a month | Cited links into your files, with the passage highlighted | Metered by pages: 500 on Expert, 5,000 on Team; OCR from Team up | Entry price: 9.99 USD a month | | Claude | Yes, up to 5 projects | The app doesn't document page citations; the API does | PDFs up to 1,000 pages and 500 MB; visual analysis only up to 100 pages | Writing and reasoning | | ChatGPT | 3 files a day | Doesn't document citations that open the page | 512 MB and 2 million tokens per file; 5 to 40 files per project | Data analysis and web research | | Perplexity | Limited uploads | Cites web sources; doesn't document pages for uploaded files | 40 MB per file | Web search with sources | | SciSpace | Basic plan | Answers linked to the cited passage | We couldn't verify them | Scientific papers | | AnythingLLM | Free desktop app, MIT license | Clickable citations to your documents | Depend on your hardware and the model you connect | Runs offline on your own machine | Data taken from each product's official pages on November 13, 2026. Sources are listed at the end. ## Which one fits what you need? If you are studying and want the most you can get for free, stay with NotebookLM. Audio and Video Overviews, reports and infographics have no direct equivalent anywhere else on this list, and the free plan covers a semester. If someone else will review your work, as with a contract, a bid or a case file, you need the page. BrainBox is an AI workspace for documents that answers with citations to the exact page. Every answer names the document and page, and selecting the citation opens the file there with the sentence highlighted, so you can [verify an AI answer about your documents](/en/blog/how-to-verify-an-ai-answer-about-your-documents) without searching by hand. If you have one PDF and little time, ChatPDF works without an account. If budget decides and your team is small, Humata Expert costs 9.99 USD a month for up to three users. If the documents can't leave your computer, AnythingLLM runs locally and can work offline. Claude and ChatGPT are good at reasoning and drafting over a PDF. The ceiling is how much fits: ChatGPT reports about 320 pages of input on Plus with reasoning models, and Claude analyzes charts and images only in PDFs of up to 100 pages. ## What does a page-level citation look like in BrainBox? **Usuario:** What are the termination rights, and where in the agreement are they? **BrainBox:** Either party can terminate for convenience with 90 days' written notice [master-services-agreement.pdf]. Amendment 2 adds a termination right if the supplier misses the service levels three months in a row [amendment-2.pdf]. *Simulation: the Assistant answers about a long contract and every claim carries the document and page.* Selecting either citation opens the PDF on that page with the passage highlighted. The Assistant searches and reads the pages it needs, or the whole document when the task calls for it, so the size of a Box is never the limit. To work across several files at once, see how to [ask AI across multiple case files at once](/en/blog/ask-ai-across-multiple-case-files-at-once). ## How do you test an alternative with your own long PDF? - **Pick a real document** The longest one you actually use: a bid with annexes, a case file or your thesis. Scanned pages are a plus, because they test OCR. - **Write three questions you already know the answer to** One from the start, one from the middle and one from the end, and note the page for each. - **Check every citation** See whether it gives the page and whether selecting it lands you on the sentence in the original. - **Ask something the document doesn't say** The tool should tell you it isn't there instead of inventing an answer. - **Ask in another language** If the document is in English, ask in Spanish and check that the citation keeps the original sentence. - **Time the checking** If confirming a claim takes longer than finding it by hand, the tool isn't saving you work. ## Where doesn't BrainBox win? On the free plan, NotebookLM's is much bigger. On generated study material, BrainBox can [turn PDFs into a podcast](/en/blog/turn-pdfs-into-a-podcast-with-ai) but doesn't make videos or infographics. On data analysis, ChatGPT is at its strongest. On entry price, Humata and Claude Pro cost less. And if you need to work offline, AnythingLLM is the pick. BrainBox pulls ahead on page-level citations, on choosing among 30+ models from several labs over the same documents, and on team work with owner, admin, editor and viewer roles.
