    You take notes. Lots of notes. And after a few months you can’t find anything anymore. Sound familiar? I used Mem intensively for a few months to see if their promise holds up: an app that organizes itself and acts as your second brain. Spoiler: the idea is brilliant, but the execution has its pitfalls.

    Mem: the company

    Mem was founded by Dennis Xu and Kevin Moody, two entrepreneurs who were frustrated with existing note-taking apps. Their vision? An app that doesn’t force you to create folders or add tags. Instead, AI should do all the organizing work.

    That vision attracted a lot of attention. The company raised millions from well-known investors and was seen for a while as the future of note-taking apps. Especially when ChatGPT didn’t exist yet, Mem was one of the few tools that really used AI smartly.

    But here’s the problem: while competitors like Notion and Obsidian continued to develop, Mem fell behind. Updates came slower. Bugs stuck around longer. And now, you wonder if Mem hasn’t completely lost its edge.

    Who is Mem really for?

    Mem is made for people who hate structure. Really. If you’re the type who wants to organize everything in folders, then Mem becomes your nightmare. The app has no folders. No notebooks. No hierarchy.

    Perfect for writers and researchers who constantly capture ideas. For people who want to dump their notes without thinking about where they belong. For anyone who believes AI can organize better than they can themselves.

    But not for teams collaborating on structured projects. Not for people who want to work offline. And absolutely not for Android users, because that app simply doesn’t exist. Also not ideal if you value stability – I’ll get to that later.

    Mem features

    Let’s look at what Mem can actually do. Because despite all the criticism, there are features that really work well.

  • AI-Powered Organization – This is the core idea of Mem. You create a note about “customer research for product X” and the AI automatically recognizes that it’s related to your previous notes about that product. No tags needed, no folders. It works surprisingly well, but only if you have enough notes. With five notes the AI does little, with five hundred it becomes magical.
  • Mem Chat – You can literally have a conversation with your notes. Ask “what were my ideas about that marketing campaign again?” and Mem searches all your notes to formulate an answer. It feels like ChatGPT, but with access to your brain. Works better than I expected, although it sometimes gives irrelevant answers if your question is too vague.
  • Smart Search – The search function is lightning fast and finds things you forgot long ago. Type half a word and Mem already understands what you mean. This is one of the few features I have nothing to complain about.
  • Related Notes – Below each note you automatically see which other notes are connected to it. Sometimes this is brilliant and you discover connections you never would have made yourself. Other times you wonder why Mem thinks your shopping list is related to your work notes.
  • Collections – Okay, so Mem doesn’t have folders. But they do have Collections, which are basically… folders? The difference is that a note can be in multiple Collections. Handy for thematic grouping, but it feels a bit like admitting that their “no structure” philosophy doesn’t quite work after all.
  • Web Clipper – Do you see an interesting article? With the browser extension you save it to Mem in one click. The text is neatly saved and the AI can search through it later. This works really well and is one of the features I use most.
  • Templates – For recurring note types you can create templates. Handy for weekly planning or meeting notes. Not groundbreaking, but practical.
  • Voice Mode – Speak your note and Mem transcribes it. Works fine for quick ideas on the go, but don’t expect perfect transcriptions of long monologues.
  • The AI organization deserves some extra attention. It’s the only thing that really sets Mem apart from the competition. In traditional note-taking apps you have to think: where do I save this? What tag do I give this? In Mem you just dump everything and trust that the AI will find it later.

    That works liberatingly. Really. You write faster because you’re no longer slowed down by organizational questions. But it also requires trust. Trust that the AI does it right. And that the data doesn’t suddenly disappear – more on that in a moment.

    Mem pricing

    Mem has a free plan, but you can’t do much with it. Maximum 25 notes and 25 chat messages per month. That’s enough to test the app, but not to use seriously.

    For real use you need Mem Pro. That costs $ 14,99 per month, or $ 12 per month if you pay a year in advance (so you pay $ 144 all at once). That’s comparable to Notion Plus ($ 10 per month) and slightly cheaper than Evernote Professional ($ 17,99 per month).

    There’s also a Teams plan, but the price isn’t publicly listed. You have to contact them for a quote, which is always a sign that it won’t be cheap.

    Honestly? For what you get, $ 15 per month is pricey. Especially since the app still struggles with stability and you don’t get an Android version. Notion offers much more functionality for less money. Obsidian is even free for personal use. The only reason to choose Mem is if you really believe in their AI vision and are willing to accept the growing pains.

    No trial available by the way. You have to pay immediately or make do with those 25 notes. That feels stingy for an app that still has so much to prove.

    What should you watch out for?

    Now we get to the pain points. And there are plenty.

    The iOS app is unstable. Crashes regularly. Sometimes the app refuses to open. Other times notes disappear temporarily only to come back later. For an app that presents itself as your “second brain” that’s downright scary. You want to be able to trust your note-taking app.

    No Android version. That’s just unacceptable for a tool that wants to be taken seriously. More than half of the world’s population uses Android, but those people can’t even try Mem on their phone.

    Synchronization is a gamble. Sometimes it works perfectly. Other times you notice that a note you created on your phone doesn’t appear on your laptop. Or vice versa. This is especially frustrating when you want to quickly look something up and realize it’s not there.

    Development is moving too slowly. People have been complaining about the same bugs for months. Features that are announced don’t come or come way too late. Dark mode, for example, was a top request for months before it was finally added – and then only for paying users.

    You’re completely dependent on the cloud. No offline mode that really works. No local storage of your notes. If Mem goes bankrupt tomorrow, you lose your data. Yes, you can export, but that’s manual work and not something that happens automatically.

    The learning curve is steep if you’re used to traditional note-taking apps. The absence of folders feels chaotic at first. You have to learn to trust the search function and the AI. For some people that never works.

    What do others think?

    The sentiment around Mem is mixed. Early users were enthusiastic about the vision and potential. But that enthusiasm has turned into disappointment.

    What people appreciate: the search function is really good. The self-organizing concept works liberating once you understand it. The AI sometimes makes surprising connections between notes that you would never have seen yourself. And capturing ideas is lightning fast because you don’t have to think about organization.

    But the complaints are persistent. The mobile app is too buggy. People are worried about data loss. Synchronization doesn’t always work. And the lack of an Android app excludes a huge group of users.

    On YouTube you can see that even early fans have dropped out. Paperless Movement, a channel that tests productivity tools, called Mem a “missed opportunity” because of the slow development. Tool Finder stated that Mem has lost its lead to competitors who innovate faster.

    The general feeling is: great idea, mediocre execution. And that’s a shame, because the concept is really good.

    Mem alternatives

    Mem not quite right? These alternatives are worth considering:

  • Notion – Offers more structure and manual control over databases and pages. Choose this if you want a flexible, all-in-one workspace that you can fully customize yourself. Notion is more stable, has more features and a better mobile app.
  • Obsidian – Stores files locally and works offline, with a focus on privacy. Choose this if you want complete control over your data and prefer to work offline without mandatory cloud sync. Also free for personal use.
  • Evernote – Traditional folder structure and powerful web clipping without AI organization. Choose this if you’re used to a classic note system with folders and notebooks. Evernote is more reliable, but lacks the AI magic of Mem.
  • Frequently asked questions

    Does Mem have a Dark Mode?

    Yes, but only if you pay. Dark Mode is available for Mem Pro users. The free plan is stuck with the light interface. Pretty strange that such a basic feature is behind a paywall.

    Can I use Mem with a non-Google account?

    No. You have to log in with a Google account. No Apple ID, no email/password, no Microsoft account. Only Google. If you object to that, you can’t use Mem.

    Is there an Android app available?

    No, and there doesn’t seem to be any change coming either. Mem is available for iOS, Mac, Windows and via the browser. Android users can only use the web version, which is not ideal for mobile use.

    Conclusion

    Mem could have been the future of note-taking apps. The idea is brilliant: dump your thoughts and let AI organize them. For people who hate structure and want to write quickly, that concept is perfect.

    But the execution leaves too much to be desired. The mobile app is too buggy. There is no Android version. The synchronization is unreliable. And the development is too slow to keep up with competitors who are innovating more aggressively.

    Would I recommend Mem? Only if you’re willing to deal with growing pains and truly believe in the AI vision. If you need a reliable note-taking app for daily work, choose Notion or Obsidian. They are more stable and offer more value for your money.

    I left Mem myself after a few months. Not because the concept is bad, but because I need to be able to trust my note-taking app. And Mem hasn’t earned that trust yet. Maybe in a year, when they’ve solved their technical problems. But now? There are better options.
