The Best OneNote Alternative in 2026 (Free and Paid)
If you want the best OneNote alternative in 2026, the short answer is: Obsidian for free offline notes, Joplin if you need open source, Notion for structured docs and databases, and Ainotely if you want your notes organized for you instead of by hand. OneNote itself is still free to use, so most people switch not for price but for one of three reasons: no native Linux app, a cluttered notebook and section system, or wanting smarter organization. This guide names each app, states its real price and free-tier limit, and tells you who it actually fits.
I run Ainotely, a note-organizing tool, so I look at every one of these apps through one lens: how much manual filing does it make you do? I researched the prices and free-tier limits below from each vendor's official pricing pages and from real user reviews (2026). I did not run lab tests on each app, so where I make a claim about pricing or limits, the exact number links to its source.

What is the best free alternative to OneNote?
The best free OneNote alternative for most people is Obsidian, which is completely free for personal use and stores your notes as plain files on your own device. If you prefer automatic organization, Ainotely is free, and Notion's free plan is generous for individuals. Evernote's free plan is the most restrictive at 50 notes total.
"Free" hides a lot of detail. Obsidian and Joplin are free because they keep your notes on your machine, so there is no cloud bill to pass on. Notion is free for individual use but charges once you need more sharing or larger file uploads. Evernote technically has a free tier, but it is now so capped that most people outgrow it in a week. The sections below break down each one.
1. Obsidian FREE
Price: Obsidian is completely free for personal use with no sign-up. Optional add-ons are Obsidian Sync at $4 per month (billed annually) and Obsidian Publish at $8 per month per site. Commercial use needs a $50 per user per year license.
Obsidian is the app most Reddit users name when they say they finally left OneNote. It stores every note as a Markdown file on your own disk, so it works fully offline and you are never locked in. It has a native Linux build, which OneNote lacks. The trade-off: you organize with folders and links instead of OneNote's notebook and section tabs, and there is no real handwriting or infinite canvas. If your notes are typed knowledge work, this is the strongest free OneNote alternative. If you live on a stylus, it will feel like a downgrade.
2. Notion
Price: Notion's paid Plus plan is $10 per month per user. The Free plan gives individuals unlimited blocks but caps file uploads at 5 MB per file, with 10 guests and 7-day page history.
Notion is the best OneNote alternative if your "notes" are really documents, wikis and databases. Where OneNote gives you a freeform canvas, Notion gives you structured pages you can turn into tables, kanban boards and linked databases. That structure is the appeal and the cost: it is more setup than OneNote, and offline support is limited compared to a local-file app. For typed, structured, shareable knowledge it is excellent. If you want a lighter swap, see Notion alternatives.
3. Evernote
Price: Evernote's Free plan is now limited to 50 notes, 1 notebook, 1 synced device, 1 GB monthly uploads and 20 tags. Its paid Personal and Professional plans exist, but I am not quoting a dollar figure here because the current paid prices could not be verified at the time of writing.
Evernote remains a capable OneNote alternative for web clipping, fast search and OCR inside images. The catch is the free tier. A 50-note cap with a single device makes it impractical as a free OneNote replacement, so treat Evernote as a paid option. If you came here from Evernote rather than OneNote, the same logic applies in reverse, and you may want Evernote alternatives.
4. Joplin OPEN SOURCE
Price: Free and open source. Optional paid Joplin Cloud sync exists, but you can also self-host sync for nothing.
Joplin is the best open-source OneNote alternative. It is free, runs on Windows, macOS and Linux, stores notes as Markdown, supports end-to-end encrypted sync, and lets you run your own sync server so your data never has to touch a third party.
Joplin is the answer to "what is the best open-source OneNote alternative?" It is the choice for privacy-minded users and Linux users who want fully auditable software. The interface is plainer than OneNote and there is no infinite canvas, but for text notes, web clips and to-dos that you fully control, nothing on this list beats it on openness.
5. Ainotely AI ORGANIZED
Price: Free.
This is the part no other roundup covers, and it is the reason I built the tool. OneNote, Notion, Obsidian and Joplin all share one assumption: you do the filing. You create the notebook, pick the section, add the tags, build the links. That manual structure is exactly what makes people abandon a note app after a few hundred notes.
Ainotely flips that. You capture a thought in text or voice, and it titles the note, tags it, links it to related notes and resurfaces it later, automatically. There are no notebooks or sections to maintain. It is a different model from OneNote's manual notebook and section tabs: instead of organizing notes, you just write them, and organization happens for you. It is free, browser-based (so it runs on any OS including Linux), and built for people whose problem is not capturing notes but ever finding them again. For a direct breakdown, see Ainotely vs OneNote, and for the wider category see AI notes apps.
Is there a OneNote alternative for Linux?
Yes. OneNote has no official native Linux desktop app, which is why so many Linux users switch. Obsidian and Joplin both ship native Linux builds, while Notion, Evernote and Ainotely run in the browser on any Linux distro. For a free, offline, native Linux app, Obsidian or Joplin are the top picks.
This is the single most common complaint in Reddit OneNote threads from Linux users, and the official OneNote experience does not solve it. If you want a proper desktop app on Linux, choose Obsidian or Joplin. If a browser tab is fine, any of the web apps here will work, and Ainotely being fully web-based means there is nothing to install at all.
Is Notion better than OneNote?
Notion is better for structured docs, databases, wikis and team collaboration. OneNote is better for freeform handwriting, stylus input and an infinite canvas. For typed notes you want organized into linked pages, Notion is the stronger choice. For pen-and-ink note-taking, OneNote still wins.
Neither is "better" in the abstract. Match the tool to your input method. If you type, build wikis and want databases, Notion is the better OneNote alternative. If you draw, annotate PDFs and write with a stylus, stick with OneNote or look at a canvas-first app instead.
Ainotely is a free AI second brain that captures notes in text or voice, then titles, tags, links and resurfaces them for you. No notebooks, no sections, no manual filing.

What is the best free alternative to OneNote?
Obsidian is the strongest fully free OneNote alternative for personal use, since it stores notes as local Markdown files with no account required. If you want automatic organization rather than manual folders, Ainotely is free, and Notion's free plan is generous for individuals. Evernote's free plan is the most limited at 50 notes, 1 notebook and 1 device.
Is there a OneNote alternative for Linux?
Yes. OneNote has no official native Linux desktop app, which is the main reason Linux users look elsewhere. Obsidian ships a native Linux build (AppImage, Snap and Flatpak), Notion and Evernote run in the browser on Linux, and Ainotely is fully web based so it works on any Linux distro.
What is the best open-source OneNote alternative?
Joplin is the best fully open-source OneNote alternative. It is free, runs on Windows, macOS and Linux, stores notes as Markdown, supports end-to-end encrypted sync and lets you self-host your own sync server. Obsidian is free for personal use and local-first, but its core app is not open source.
Is Notion better than OneNote?
Notion is better for structured docs, databases, wikis and team collaboration. OneNote is better for freeform handwriting, stylus input and a true infinite canvas. If your notes are mostly typed and you want them organized into linked pages and databases, Notion is the stronger OneNote alternative.
Can I use Obsidian instead of OneNote?
Yes, if you are comfortable with Markdown and folders instead of OneNote's notebook and section model. Obsidian keeps every note as a plain text file on your device, works fully offline, and is free for personal use. You lose OneNote's pen and infinite-canvas drawing, so it suits typed knowledge work more than handwritten notes.
Is there a free alternative to OneNote that works offline?
Yes. Obsidian and Joplin both work fully offline because they store notes as local files on your computer, and both are free. You only need an internet connection if you choose to turn on optional sync between devices.
What can I use instead of OneNote after Microsoft discontinued the Windows 10 app?
Microsoft retired the older OneNote for Windows 10 app and now points users to the single OneNote app on Windows, which is still free. If you would rather switch, Obsidian (free, offline), Notion (free plan or $10 per month Plus) and Ainotely (free, AI organized) are the most common replacements.
