Choose Gemini Notebook, formerly NotebookLM, if your main job is researching sources, asking cited questions, and producing several study artifacts from one notebook. Consider Repeto after release if your priority is a durable flashcard collection with FSRS review scheduling and an Anki .apkg exit path, but Repeto is still pre-release and cannot match Gemini Notebook’s current availability or research depth.
Disclosure: Repeto publishes this comparison and therefore has a commercial interest. We link to first-party product sources, state where Gemini Notebook is stronger, and separate Repeto’s pre-release target from features available to the public. Facts and prices were checked on August 21, 2026.
Repeto vs Gemini Notebook at a glance
| Decision | Gemini Notebook (formerly NotebookLM) | Repeto |
|---|---|---|
| Public status | Released browser, iOS, and Android product; mobile features and regional availability vary | Web app is in pre-release; an iPhone/iPad update is in preparation; Android is unreleased |
| Best fit | Researching, synthesizing, and asking cited questions across a source collection | Evaluating a deck-first path from source material to long-term scheduled recall |
| Source inputs | PDFs, Word (.docx) and PowerPoint (.pptx) files, Google Docs/Slides/Sheets, pasted text, Markdown, TXT, CSV, images, audio, ePub, web URLs, public captioned YouTube URLs, and Gemini chats | Pre-release codebase includes material ingestion and editable AI cards; each live source path still needs verification |
| Web research | Fast Research finds web or Drive sources; Deep Research can browse many websites and import a report and sources | Pre-release codebase includes material ingestion and editable AI card generation; public research and citation behavior is unverified |
| Flashcard flow | Adjustable generation followed by Got it/Missed study, saved progress, shuffle, and retake options | Pre-release codebase generates editable cards inside a deck |
| Review scheduling | Official help documents saved progress and missed-card repetition but does not identify a spaced-repetition algorithm or due schedule | Pre-release codebase uses FSRS; public longitudinal behavior has not been demonstrated |
| Export | Generated flashcards can be downloaded as CSV | Pre-release codebase exports supported decks as .apkg; broad round-trip fidelity is not yet claimed |
| Platforms and offline | Browser, iOS, Android; mobile supports fewer source and output types, and offline flashcard study is not documented | No generally released Repeto surface; complete offline behavior is unverified |
| Sharing | Private viewer/editor access and public notebook links; account and feature eligibility vary | Pre-release codebase includes a shared-deck market, but its public availability, inventory, and activity are unproven |
| Price | Free Gemini Notebook Standard plus higher-limit Google AI, eligible Workspace, and Cloud plans; limits and prices vary by plan and region | Repeto 2.2 has no final public price that should guide a purchase decision |
The practical distinction is research notebook versus memory system. Gemini Notebook is already a capable source-grounded research product that also makes flashcards. Repeto’s comparison case is a pre-release deck and scheduling direction, not a claim that it researches better than Google.
Where Gemini Notebook is better than Repeto
Gemini Notebook has a real research workflow, not just file upload
Gemini Notebook should not be described as upload-only or unable to use the current web. Fast Research searches the web or accessible Google Drive files and lets the user choose sources to import. Deep Research can automatically browse up to hundreds of websites, produce a multi-page report, and bring the report and selected sources into a notebook. Deep Research is subject to plan limits and is currently restricted to users over 18.
Once sources are in the notebook, questions and generated artifacts can remain grounded in the selected material. Google also exposes citations and lets the learner open the supporting source. Repeto’s claim ledger verifies material ingestion and editable AI cards in the current codebase; it does not establish a comparable research or citation workflow.
Gemini Notebook supports more source and output types today
Google’s current source list includes audio, pasted text, Google Docs, Slides and Sheets, images, DOCX, TXT, Markdown, PDF, CSV, PowerPoint, web pages, ePub, public YouTube videos, and Gemini chats. Google Drive sources can update from their originals, while web imports capture text and YouTube imports use the available transcript.
The same notebook can produce more than cards: quizzes, reports, audio and video overviews, mind maps, infographics, slide decks, and data tables are among the documented artifacts. Repeto is intentionally more focused, but focus is not automatically an advantage for someone who wants one broad study workspace.
Gemini Notebook has stronger distribution and collaboration
Gemini Notebook is available in a browser and through iOS and Android apps, subject to Google’s country, age, account, and rollout rules. A notebook owner can invite viewers or editors and, on eligible consumer accounts, publish a notebook by link. Editors can work with the notebook’s sources and notes.
Repeto has no generally released surface under its current identity. Its pre-release shared-deck routes are not evidence of an active catalog or collaboration network.
Where Repeto’s pre-release target may fit better
These are intended or current-codebase differences. They are not public-availability wins.
Repeto is designed around scheduled card review
Gemini Notebook’s documented flashcard session uses Got it and Missed, saves progress, and lets the learner retake the same cards, all cards, or only missed cards. Google’s official flashcard documentation reviewed for this article does not identify a spaced-repetition algorithm, publish scheduling rules, or describe a calendar-based due queue.
That documentation gap is not proof that no scheduling behavior exists anywhere in the product. A hands-on test should observe what returns over several days.
Repeto’s pre-release codebase uses FSRS for review scheduling. That is a clearer target proposition for a learner whose primary question is “what should I recall today?”, but Repeto still needs public seven-day and longer tests.
Repeto is building an Anki-compatible exit path
Gemini Notebook can download generated flashcards as CSV. CSV is useful for inspecting and moving question-and-answer text, but Google’s help does not document an Anki .apkg export or transfer of templates, media, scheduling, and review history.
Repeto’s pre-release codebase imports supported Anki .apkg files and can export a deck as .apkg. That is a meaningful target advantage for learners who want an Anki-compatible backup or exit. It is not yet a losslessness claim: Repeto still needs a published corpus covering custom templates, cloze cards, media, non-Latin text, modern package variants, and review history.
Repeto is deck-first rather than notebook-first
Gemini Notebook’s cards are generated artifacts inside a source notebook. Repeto’s current codebase supports manual decks and editable AI-generated cards inside a deck; its intended workflow is deck-first rather than notebook-first.
This could reduce cleanup and make a collection easier to maintain across courses. It must be measured. Gemini Notebook may produce better grounded cards because its research and source-selection system is more mature.
Where Repeto is worse or less proven
- Gemini Notebook is released on the web, iOS, and Android; Repeto is not generally released under its current identity.
- Gemini Notebook has a much broader verified source list, richer source inspection, citations, Fast Research, and Deep Research.
- Gemini Notebook produces several useful artifacts besides flashcards. Repeto’s narrower deck workflow will not replace that research workspace for many learners.
- Repeto has not published a live source-by-source capability matrix, AI-card accuracy test, or citation-coverage result.
- Repeto has no released Android app, and complete offline behavior is unverified.
- Repeto’s
.apkgimport/export still lacks a public broad-fidelity corpus. - Repeto has less evidence about scale, support, long-running sync, collaboration, and reliability during an academic term.
Gemini Notebook’s weaker fit for scheduled retention does not make pre-release Repeto the better immediate choice. A learner can use Gemini Notebook today and move exported CSV data elsewhere if a dedicated scheduler is needed.
Card creation: source-grounded artifacts or an editable deck queue
In Gemini Notebook, the learner chooses notebook sources, opens the Flashcards artifact, and can change the prompt, card count, and difficulty. This makes it easy to create a source-specific set after research. It also keeps the cards near the notes, reports, chats, and citations used to understand the subject.
Repeto’s pre-release codebase generates editable cards inside a deck. The useful comparison is not how quickly either app displays 20 cards. Count unsupported answers, duplicated ideas, ambiguous prompts, and the minutes needed to make the set study-ready.
Reviewing: Got it/Missed or FSRS scheduling
Gemini Notebook lets the learner reveal and mark a card Got it or Missed. Progress persists, and a completed session can be repeated with all cards or only missed cards. Those controls support active recall and immediate correction.
Repeto’s pre-release codebase uses FSRS for review scheduling. A named scheduler can make the model easier to compare with other serious flashcard systems, but its presence does not guarantee better learning.
Do not decide this category from labels. Record the same five concepts as not recalled in each product, return after one hour, one day, and one week, and record what each product actually asks you to study.
Portability, ownership, and deletion
Gemini Notebook downloads generated flashcards as CSV. Its help says imported sources are copies or synchronized versions, and it cannot edit or delete the original Google Drive file. Google says it does not claim ownership of generated Gemini Notebook content and does not use uploaded sources or chats to train foundation models unless the user provides feedback. Plan-specific Google Workspace or Cloud terms may differ, so institutional users should check the agreement attached to their account.
Repeto’s pre-release target is stronger format portability through supported .apkg import and export. Its current legal copy says decks, notes, cards, and imported material remain the user’s, while granting the limited rights needed to store, process, sync, display, and perform requested AI generation. That policy and the implementation still need to match at public release.
Keep the original source files and an independent copy of important decks in either workflow. A CSV of card text is not the same as a backup of media, templates, and learning state.
Platforms, offline use, sharing, and price
Gemini Notebook is available in a browser and on iOS and Android, with country and device requirements. The mobile app supports generating and reviewing flashcards and quizzes, but Google documents fewer mobile source types and no mobile notes, mind maps, reports, or data tables. Its mobile help explicitly documents downloading Audio Overviews for offline playback; it does not document offline flashcard study. Treat offline cards as unverified until tested on the current app version.
Gemini Notebook Standard is free. Google’s August 2026 limit table lists 100 notebooks, 50 sources per notebook, and 10 flashcard generations per day for Standard, with higher limits in Plus, Pro, and Ultra. Limits are explicitly subject to change. Paid access comes through Google AI, eligible Workspace, or Cloud plans, so use the checkout for the correct country, account type, taxes, and bundle rather than assuming one global price.
Repeto has no equivalent released offer yet. Its web app is pre-release, the iPhone/iPad update is in preparation, Android is unreleased, and its final price and public limits should be checked only after launch.
Run the same source-to-memory trial
Run the Repeto side only with legitimate pre-release access or after release.
- Choose a two-page PDF with one table, one image, and one easy-to-misread qualification. Add one captioned public YouTube video on the same topic.
- In Gemini Notebook, import those sources and use Fast or Deep Research for one current question. In Repeto, use only source paths that are available in the build being tested.
- Ask each product for 20 medium-difficulty cards with one answerable idea per card and no facts outside the selected sources.
- Count cards with a traceable citation, unsupported answers, duplicates, overloaded prompts, and cards you would delete.
- Time the edit-and-cleanup pass. Record which fields and citations remain attached after editing.
- Record the same five concepts as not recalled and the remaining concepts as recalled using the controls available in each product. Reopen both products after one hour, 24 hours, and seven days; record the queue and any visible next-review information.
- Export the cards. Inspect the CSV and
.apkgin fresh tools, checking text, media, templates, source references, and review state. - On mobile, load the material, disconnect the network, try a review, reconnect, and verify progress on another device.
- Share the material privately with a second account, then remove access and confirm what the recipient can still see.
The useful outcome is not the number of generated artifacts. Measure supported claims, repair time, completed reviews, and whether the resulting study collection remains usable outside the product.
Which should you choose?
Choose Gemini Notebook if you need a released tool now, research across uploaded and current web sources, want citations, work in Google Drive, or want quizzes, reports, and media overviews alongside flashcards.
Consider Repeto after release if a deck-first workflow, explicit FSRS review, and Anki .apkg portability matter more than research breadth. Keep independent backups and verify Repeto’s import, export, sync, and offline behavior with your own deck before committing.
Gemini Notebook is the stronger research and immediate-use choice. Repeto’s future case is durable scheduled retention and portability—not a claim that Gemini Notebook is merely a source-bound card generator.
