Hey everyone - I made an initial version of this at the TC Disrupt Hackathon, see here: Memstash. It was build in 20 hours so it's obviously very very MVP, but we ended up winning trips to Paris as well as getting over 50k visitors and 5k signups (mostly via a Hacker News post).

I think that the response generally proves that there are definitely people interested in this sort of thing - but return traffic hasn't been great, which is understandable given how basic the functionality is. Anyway, would love to get your feedback on what I've built thus far.

Great feedback - thanks Shannon.

Interesting. Thanks for pointing this out. I'm not sure whether this is necessarily a bad thing, but it's good to know that it is a known geek archetype.

It implies that its a problem a lot of geeks have and that there's a market. Sounds like a problem that is easy to solve moderately well but has not yet been solved with excellence.

This is great - I'm going to take a look through the code and see if I can get it running on a test server.

Persol, that list of competitors is massively helpful, thank you.

I'd love to hear more about your experiences, and to get a better of idea of exactly what you had built. I think what I have in mind is a more mass-audience version of SRS (see my response to Micaiah above) rather than a more traditional Anki-type system.

I'd love to know how you were monetizing the service, and if there are any screenshots of what the site looked like. Did you offer a mobile application? Did you try to push people to engage via push notifications at all? I think this is defi... (read more)

Here's the actual PHP code, weighing in at 18Mb. It's probably the best way to get a feel for what it was, and it might help you decide what to do. It includes: * most of the site code - This code is from about a month before I moved onto a more rewarding project, but it's the last full set I have. * automatic stylesheets/icons for iPhone and Android (not an application, but did create an icon on the home screen) * a bunch of draft banner ads - the animated GIFs summarize how the site worked * a research folder with information on SRS publications * screenshots of other SRS engines This version may not have the correct repetition calculation. Due to the inherent time factor, it was a hassle to test, so I didn't fix that part of the code until later. It was admittedly an ugly (but fast loading) site. After a few weeks of cheap banner ads and seeing the minimal reuse, I just set it to coast until the year ran out. I did do some A/B testing with email notifications about a month in. It didn't have a measurable effect of return use. Monetization was via banner ads. Via A/B testing, the best location for the ad was under the card's question. Once flipping the card, the ad was hidden. I also deactivated the ads for awhile too see if they were too intrusive; return visitors didn't improve. I also incorporated graphics and audio, since the most successful SRS systems seem to revolve around vocabulary. I personally used it to help learn basic Mandarin for use with my in-laws... but it is a boring way of learning a language. While it is much more effective than Rosetta Stone, it is very difficult to stay engaged.

MIcaiah, thanks for the detailed and well thought-out response. I'll try and respond to some of your thoughts:

I imagine this would be very hard to monetize and get customers as-is.

As far as monetization goes, I think the best route would be to charge online education providers on per-API-call basis. The end goal would be to become something akin to the "Twilio of online learning." With a sufficiently developed system, I think it'll be possible to convince companies in the online learning space that this is a worthwhile value proposition for ... (read more)

Congratulations; you've motivated me to decide I'll use some sort of SRS to remember the names of my students, the next time I have to TA a class (most likely in January). I'll find something to use one way or the other, but if you manage to provide a working alternative by that time, I promise to use it.

All three look promising. However, you might be pidgeonholing yourself by trying to go back to the "SRS as generalized learning tool". For most people, it would appear as if that's too abstract. You may be much better off focusing on the most generally appealing use case (The name-face ID one sounds the most promising; I can't imagine any people who weren't already self-motivated autodidacts using the first two). In fact, it might turn out to be much better than than the original Anki-as-service app; it appears to me that many more people view "oh god what's her name I just met her a week ago THINK" as a problem than "Oh, hm, it appears I've forgotten how to say 'praying mantis' in Japanese". To extend the Name-Face identification concept, you could also add things such as people's birthdays, dates of important events such as anniversaries into it; although I'm not sure how many of those things aren't problems anymore because of calenders etc. I can't comment too much on the "Twilio of online learning" idea; I don't know the interest level of online courses such as Udacity, Coursera and Codeacademy on something like that. Although I will warn that there's a real risk that it'll be treated as "just another complicated feature that I don't need to use" by the average student. But if you get a hardcore userbase who are happy with the product and willing to give feedback then you're in much better shape than trying to arbitrarily design for the "average" user.

I've just posted a couple of ideas that involve Anki-like systems, it'd be great to get your feedback. In general I think that anything that promotes wider use of spaced repetition and optimized learning techniques has massive societal.

sinak220

In addition to my last idea, here's another thing I've been kicking around:

Anki-as-a-Service

Problem: Anki is great, but the user interface is mediocre and it acts as a standalone application on the platform of your choice (desktop, mobile, etc).

Solution: A hosted version of Anki accompanied by a mobile application that allows users to enter items manually, capture items from the browser via a javascript bookmarklet, or allows third parties to submit information for users via an API. In essence this would amount to "learning as a service" and co... (read more)

Just a word of caution: this seems to be the idea almost every geek I know thought of doing (including myself, had a prototype going 4 years ago). You can draw some conclusions from this.

I imagine this would be very hard to monetize and get customers as-is. The below is merely a brief list of problems that I've thought about

The average user needs to be sold on the effectiveness of a product very fast, on the first usage (or perhaps even sooner!) in order for them to continue using. However, SRS software in general are almost by definition antithetical to that goal: Their benefits do not come until far into the future, worse still it's an undefined time in the future. Sure you can use arguments about the benefits of SRS and the psychology o... (read more)

I'm an entrepreneur looking to found or join my next project, so I'm particularly in interesting what people are thinking about and working on.

An Improved Platform for Reading

Problem: We forget almost everything that we read. Current reading platforms (e.g. Kindle, Instapaper, Nook, web browsers) are very crude at helping us make the most of the time we spend reading.

Solution: A platform that uses the latest in efficient learning techniques to improve the quality of recall from reading. By adding interactivity and enhancing the reading experiencing using... (read more)

I met a dude two weeks ago at a SuperHappyDev meetup in Mountain View, doing a very similar thing. Had been working on it as a Phd. thesis for a few years, but now wants to commercialize it. He was looking for a co-founder too. PM if you want his details.

I think this is a great idea, especially in regards to modulization. I can see such a service being used in conjunction with existing interactive book platforms as well as standing on its own. I am very open to contributing my ideas and experience (software development and pedagogical technologies) to further this project.

I talked to someone building the browser plugin version of this a year ago. Sorry, I don't remember what it was called.
