The best note-taking app with nested folders depends on what you need after filing a note. BrainDen fits students who want course folders connected to source material and active-recall tools. Obsidian suits learners who want local Markdown files and deep customization. Joplin is strong for open-source notebooks and flexible sync. UpNote offers a polished, simpler hierarchy across desktop and mobile. Standard Notes is the privacy-focused option, although folders require a paid plan.
All five support a real parent-and-child hierarchy. They differ in how notes are stored, how well mobile organization works, and whether the folder is only an archive or part of a study workflow.
Quick picks: Choose BrainDen for learning materials and revision, Obsidian for local files and links, Joplin for open-source control, UpNote for a clean cross-platform notebook tree, or Standard Notes for encrypted notes with paid folder organization.

What counts as a nested folder?
A nested folder is a folder placed inside another folder. For a student, that makes a structure such as this possible:
2026 Fall
├── BIO 204
│ ├── Module 1: Cell structure
│ │ ├── Lectures
│ │ └── Readings
│ └── Exam revision
└── HIST 110
├── Primary sources
└── Seminar notes
Tags, links, spaces, and search can all improve organization, but they do not replace this hierarchy. A flat list with a BIO 204 tag is useful filtering, not a folder inside a semester and course.
This distinction matters when a library grows. Folders give every note a stable course location. Links can then record relationships that cross the hierarchy. Our guide to organizing study notes digitally explains how those two layers work together.
How we compared these apps
Each pick had to document parent-and-child folders or notebooks on an official product page. We then compared five questions that matter to students:
- Can you create and rearrange the hierarchy on the devices you use?
- Does the app preserve a route back to the lecture, PDF, recording, or reading?
- Can related notes connect across folders?
- What can you do with the material during revision?
- What does folder organization cost?
There is no universal winner. A local-first Markdown system and an active-recall study system solve different jobs, even when both show a folder tree.
1. BrainDen: best for a connected study workflow
BrainDen is the most study-specific option in this list. Its nested study folders can represent semesters, courses, modules, weeks, lectures, projects, and revision topics. Notes can keep their original PDFs, recordings, photos, text, audio, and supported video links connected to the structured note.
The folder is therefore the start of a workflow, not only a storage location. A student can link related ideas across folders, read several selected notes continuously, export selected notes together, and create flashcards, quizzes, mind maps, or Explain It Back practice from checked material.
Best for: Students who want one path from source material to an organized library and active recall.
Limitations: BrainDen is learning-first rather than a general Markdown editor or team workspace. It does not offer the plugin ecosystem or direct filesystem control of Obsidian. Folder sharing includes the notes directly inside the chosen folder, not a recursively published subfolder tree.
Pricing: BrainDen is free to try. Generation limits and some advanced features require BrainDen Pro. Subscription prices and introductory offers can vary by platform and storefront, so check the offer shown on your device.
2. Obsidian: best for local files and customization
Obsidian stores notes as Markdown files inside a local folder called a vault. Its official File Explorer guide documents creating subfolders, moving files and folders by drag and drop, and browsing the resulting folder tree.
That direct file structure is useful if you want readable files outside the app, extensive links and backlinks, or a system you can customize with community plugins. It also suits students who already know how they want to organize their material.
Best for: Learners who value local files, Markdown, links, and control over their setup.
Limitations: Obsidian gives you building blocks rather than a guided study loop. Capturing source material, generating practice, sharing, and multi-device sync may require optional services, plugins, or a workflow you design yourself.
Pricing: The core app is free without limits. Obsidian pricing lists optional Sync at $4 per user per month and Publish at $8 per site per month when billed annually. Students and faculty can receive a 40% discount on Sync and Publish.
3. Joplin: best open-source nested notebooks
Joplin organizes notes into notebooks and sub-notebooks. Its official sub-notebook documentation describes a tree of notebooks that can group course or project material under a parent.
The app is open source, supports Markdown, and offers several synchronization routes. Joplin Cloud adds managed sync, publishing, and collaboration, while experienced users can choose other supported sync targets or self-hosted options.
Best for: Students who want open-source software, Markdown notes, and more control over synchronization.
Limitations: The hierarchy has an important device caveat. Joplin says sub-notebooks can currently be organized only in the desktop app. Mobile can display and expand the tree, but it cannot move sub-notebooks between parents. That is a meaningful constraint if a phone or tablet is your main device.
Pricing: The Joplin apps are free. Joplin Cloud plans start at €2.40 per month for Basic and €4.79 for Pro when billed annually. Joplin advertises a 50% education discount for students and teachers who verify through a school email address.
4. UpNote: best simple hierarchy across devices
UpNote uses notebooks and sub-notebooks in a clean interface. Its sub-notebook guide documents creating and changing parent notebooks on Mac, Windows, Linux, iOS, and Android.
That consistent mobile behavior gives it an advantage over Joplin for students who frequently reorganize notes on a phone or tablet. UpNote also supports links between notes, attachments, exports, and separate spaces.
Best for: Students who want dependable nested notebooks without maintaining a complex system.
Limitations: UpNote is a general writing and organization app. It does not provide BrainDen's source-to-flashcard workflow or Obsidian's open file-and-plugin model. The free plan is suitable for testing but is capped at 50 notes.
Pricing: UpNote's public pricing lists a free plan with up to 50 notes and Premium at $1.99 per month or $39.99 for a lifetime purchase. The company notes that regional prices and taxes may vary.
5. Standard Notes: best for privacy-focused organization
Standard Notes is built around encrypted, cross-platform notes. Its features page says nested folders are created from tags with drag and drop, so the visible hierarchy is generated from the tagging system rather than a conventional filesystem.
This approach fits learners who prioritize encrypted notes, long-term access, and a focused writing environment. The app runs on web, desktop, iOS, and Android.
Best for: Privacy-conscious students who need structured text notes across several devices.
Limitations: Nested folders are not part of the free plan. The free tier includes tags and plain-text notes, while folders and richer note types require Productivity. It is also a general note app, so study practice needs a separate method or tool.
Pricing: Standard Notes plans list a free Standard tier, Productivity at $90 per year, and Professional at $120 per year. The company offers students a 30% discount.
Why HyNote is not in the five
HyNote is a close AI note-taking competitor and may still suit learners who want recording, transcription, and broad content capture. Its current folders feature page documents custom folders, multi-format content, and cross-device sync, but it does not document parent folders, subfolders, or another nested hierarchy.
Because this comparison requires verified nesting, we have not counted HyNote as a nested-folder pick. Its folder page also contains conflicting statements about whether AI suggests folder placement, so evaluate the current product directly if that feature affects your choice.
Which nested-folder app should a student choose?
Choose based on the job you repeat each week:
- Choose BrainDen if lectures, PDFs, recordings, and practice should stay in one connected study system.
- Choose Obsidian if local Markdown files, links, and customization matter more than guided study features.
- Choose Joplin if you want open-source notebooks and can organize the hierarchy primarily on desktop.
- Choose UpNote if you want a low-friction notebook tree that you can rearrange on desktop or mobile.
- Choose Standard Notes if encrypted writing and cross-platform access justify paying for folders.
Before migrating a whole library, test one real course. Create a semester folder, add one course and two modules, import or write five notes, link one relationship across modules, and complete one revision session. That trial reveals more than a long feature checklist.
Frequently asked questions
Are folders better than tags for study notes?
They solve different problems. Use folders for stable course location and tags for changing properties such as needs review, essay evidence, or exam priority. Avoid building two competing hierarchies.
Should a student use folders or backlinks?
Use both when the app supports them. Folders keep the syllabus structure visible. Links and backlinks connect a lecture to a reading, prerequisite, example, or criticism in another folder. See how to use bidirectional links for studying without creating a noisy graph.
How many folder levels are useful?
Start with semester, course, and module or topic. Add a fourth level only when it solves a recurring navigation problem. A deep hierarchy is not automatically a useful one.
Can nested folders replace a revision system?
No. A folder helps you find material, but it does not test whether you can retrieve or apply it. End each organization session by selecting related notes and answering a question without looking.
Test the hierarchy with one course
The best note-taking app with nested folders is the one that makes both filing and studying easier. Build a small version of your real semester, confirm that the hierarchy works on your main devices, and check what happens after a note is stored.
Set up a semester, course, and module structure with BrainDen, then continue with Web, iPhone & iPad, or Android.
