The topic of Forget OneNote, Evernote, and Notion, this free open-source note-taking app is way… is currently the subject of lively debate — readers and analysts are keeping a close eye on developments.
This is taking place in a dynamic environment: companies’ decisions and competitors’ reactions can quickly change the picture.
Sometimes people spend months building a digital second brain, only to realize their most valuable thoughts are being held hostage. Whether it’s proprietary file formats (looking at you, Evernote) that refuse to export cleanly or a cloud-only architecture that goes away the moment you go offline, most modern note-taking apps feel restrictive.
That’s when I found Affine. It didn’t win me over with just a slick UI or fancy widgets; it won me over by offering true control over my data.
Data locking is the ultimate nightmare for anyone building a digital second brain. for example, I was an Evernote power user. However, it saves your notes in a proprietary .enex format. While you can export them, try opening that file in anything other than Evernote.
It’s a mess of XML that requires a specialized converter just to make it readable as Markdown or plain text. If you have thousands of notes with PDF attachments and images, Evernote’s export often strips the metadata or loses the folder structure.
Now, let’s have a word about modern solutions like Notion. It is beautiful, flexible, and hard to replicate elsewhere. When you export a Notion page to Markdown, you lose the magic. Your linked databases turn into flat, ugly CSV files that no longer talk to each other.
Also, you are entirely dependent on the cloud. You can’t just grab files from your hard drive because they don’t exist there.
If Notion’s servers are down, or if they decide to gate a feature behind a new paywall, your data is trapped behind their login system.
Here is where Affine comes into play. It didn’t wow me with its long list of features (more on that in a minute). I was impressed by how it manages my data.
With most apps, your notes exist on someone else’s server. If your Wi-Fi goes down, your productivity stalls; if the company goes bust, your notes vanish.
Affine flipped that script for me. It uses a local-first architecture, which means my data lives on my device. When I’m typing, I’m not sending requests to a distant data center; I’m writing directly on my own hardware.
Now, I can put down my raw ideas, half-baked business plans, and personal journals without thinking twice. If I want to keep my notes completely offline, I can. If I want to self-host my own storage, the option is there.
The most refreshing part of using Affine is the realization that they aren’t trying to lock me in.
With Affine, I don’t need to pick between a document and a whiteboard. Affine is the first tool that finally stopped forcing me to choose. It offers edgeless versatility.
Before Affine, if a meeting note started turning into a complex flowchart, I had to stop my momentum, open a separate app like Miro, and try to recreate the context.
With Affine, I don’t have to switch apps. I can turn my note into a whiteboard card with just a single click. The moment I need to see the big picture, I click one button to enter Edgeless Mode.
Suddenly, my linear document is sitting on an infinite canvas. I can drag these cards around, group them, and physically see the connections between ideas that were previously buried five scrolls deep in a doc.
I can use arrows, shapes, frames, pen, and other tools to create a perfect brainstorming session. It’s easily one of the best features of Affine, and once you get the hang of it, there is no going back.
Affine isn’t just a private big picture tool. It’s a workhorse for daily organization. It feels like someone took the best parts of Notion and Obsidian, polished them, and gave it an open-source tag.
I used to have dozens of ‘Untitled’ notes scattered across different folders. Affine’s Journal feature solved that instantly. Every morning, I open the app, and there is a fresh page waiting for me, automatically dated and categorized.
Like Notion, Affine’s slash command is highly effective. I don’t need to leave my keyboard ever. Whether I need to insert a Kanban board or a sub-page, I just hit / and keep moving.
In terms of note organization, I use folders, tags, and, of course, a whiteboard to keep my thoughts arranged logically. I was also glad to see native mobile apps on both iOS and Android.
And if you are dealing with thousands of notes, use Collections. It is essentially a smart folder where I can add docs manually or automatically by rules. For instance, I can create a ‘Finance’ collection that consists of all the notes with #receipt, #money, #creditcard, and other relevant tags.
Thanks to Affine, you shouldn’t trade away your data sovereignty for the sake of convenience. By offering a local-first philosophy and open-source transparency, it has earned my trust in style. If you are tired of renting your own digital brain, it’s time to give Affine a shot.
