This seems great, but I dont see a way to create a new tree?

Hey. For the past 2 years, I have been working on LearnObit ( https://learnobit.com https://learnobit.com): a new and rapid way to learn anything. When I first started programming, I used Anki and the old tried-and-tested Spaced Repetition algorithm. This was great for word-pairing (such as when you learn French or another language), but didn't suit for more complex, general topics like Mathematics or Physics. Because of that, Spaced Repetition has always been widely over-looked despite its proven effectiveness in learning-retention. I wanted to unlock this effectiveness for a wider audience by building LearnObit, a note-taking tool which lets you organize and structure complicated/layered information then manage this via Spaced Repetition as easily as you use flash cards today. I'll be here anytime if you have any questions for me. Thanks for your time.

"Planning for your learning will be relentless as your knowledge (not information) will be manageable" I think a proof reader might be valuable for your site, I've no idea what the above sentence, and several like it, really says.

  Thank you so much for your suggestion; I didn't notice it. As you can see, I'm not a native English speaker. I'll make some corrections to the content on the landing page.

  I've received the correction: Planning for learning will be non-stop, as your knowledge (not information) is manageable. Perhaps now the sentence is understandable.

    It's not so much that that one sentence was a problem, it's that all the text is hard to read and understand. Marketing software is incredibly hard, commonly much harder than developing it. You might consider launching your software first in your first language where it will be easiest for you to both write about and assess others writing about your software.

      Thanks for the advice. I did not notice that it's that terrible level. I'll get this corrected overall.

        Hello. It's not terrible; I think most of it makes sense but it is a bit hard to read at times. Maybe a proof reader could help make it less heavy (i.e. more simple english.) There's quite a lot of content on the front page and a modern users attention span is quite short. HN wants to make everything seem and feel exactly the same but I personally like the flow of words and information - you can tell you've invested yourself into the software. Will give this a spin.
        SunghoYahng 7y ago
        Okay. I understand now that the problem is to reduce the amount of complexity. And thank you for the compliment!

The web version [0] does not work for me. It shows a blank page. Browser is Firefox 68.5.0esr (64-bit). This is the error I get: "SyntaxError: invalid regexp group index.46eed2a4.js:1:1" [0] https://app.learnobit.com/ https://app.learnobit.com/
- thepete2 7y ago
  Of course it works on chrome ... Do people not test their apps on firefox anymore?
- SunghoYahng 7y ago
  Thanks for the feedback. The web version was added a while ago. I wanted people to use LearnObit as a desktop application. But I'll make it work in Firefox.
- SunghoYahng 7y ago
  I'm sorry I didn't solve the problem until late. This situation was caused by Firefox's lack of support for RegEx's lookbehind assertion. I'm trying to create a non-lookbehind version for RegEx.

Hey your Firebase OAuth isn't working. "This domain (app.learnobit.com) is not authorized to run this operation. Add it to the OAuth redirect domains list in the Firebase console -> Auth section -> Sign in method tab." Need to add the actual domain in your Google console.
- SunghoYahng 7y ago
  That's right. I fixed it. I forgot to set it up after adding the web version. Sorry for the inconvenience.
SunghoYahng 7y ago
Thanks for the feedback so far. I didn't even notice that the app had this many problems. I'm embarrassed to show you an incomplete app, but anyway I think now I've fixed all the parts which received the feedback, Including proofreading the entire contents of the landing page.

I would love to try this on mobile, but it didn't seem very usable in that context :(
- SunghoYahng 7y ago
  Actually, it's not. LearnObit is now for the desktop. I think it fits LearnObit to be on the desktop, where the user sits down in one spot and concentrates deeply on using it. I will release a mobile version later, though.

I like this, because it's a tree style note system, which I go a bit crazy for, as I haven't found a truly great one yet (my dream is Dynalist, but faster on mobile and self-hostable FOSS). The features of this seem pretty insane as it looks like it allows stuff like drawing something for a bullet point, which would be perfect for some uni modules (I currently just do full hand writing for those, mostly in bullet point lists, which is still pretty much how I think, but a lot of the advantages are obviously lost). Convinced you'd be able to sustain the project that way, would you consider opening up the project's source? My motivation for wanting this ties a bit into: > I will not disappear. Moving forward, LearnObit will only improve with new features and polished programming. I promise. Your promise isn't worth much. You will most certainly disappear at some point (when you die, which might be today [this is not a threat]) and will likely lose interest far, far sooner. If I made a comprehensive knowledge base I'd want everyone to be able to access it, not just people with a subscription to a SaaS product, which will quite certainly become disfunct within 100 years. I'd also want to be able to extend it with my own scripts and features. All these problems could be solved relatively easily (but perhaps not as profit-deliveringly as you wish). Okay, that's the free software preaching. Conceptually I like the idea of this app, an important part of my bullet point list consists of knowledge base stuff. Other key components are thoughts that need to be noted somehow and planning of things (which might be a great addition to your product, as you are already creating to do-items in a way). Keeping all of these things in one app would be something between good and essential for me, as I think I would like some portability between the use cases. I haven't even looked at LearnOrbit yet in detail, but the thought of a newcomer in the outliner-niche and your novel concept definitely excite me.

  Here's another thing about tree style note taking and the structure of knowledge that maybe bugs me a bit more than it maybe should: Yes, for about 95% or (much) more of nodes the structure is hierarchical, but there's still a somewhat significant amount of nodes for which the conceptual structure would actually be a directed graph (here's an extreme but common example: You want to make a list of cars. Do you group them by manufacturer, type, price ...? Not at all? That'd be extremely hard to navigate. You'd also want to be able to easily change it, right? Another example would be general cross-linking). Have you thought about this before? Would it be feasible to implement something like this in your app? Does anyone else know whether there are tools out there for this already? I wouldn't be mad about a mind map view (that is not absolute garbage because it's a swing app that's ugly and only available on desktop linux or offers per node styling options [I see how it's good for presentation, but it's just terrible for pure structure keeping] ...), but I'd prefer the main view to be tree-based as it's by far the best representation (I have found so far) for the by far most cases.
