Questions & Answers

As answered by people managing Mem and Space Repeat.

What makes your product unique?

Space Repeat's answer:

Space Repeat removes everything that distracts from actual learning: no feature overload. It focuses purely on active recall and spaced repetition, the two techniques with the strongest scientific backing for long-term memory.

Why should a person choose your product over its competitors?

Space Repeat's answer:

Most study apps optimize for engagement, not retention. Space Repeat is intentionally minimal. It shows you cards exactly when you're about to forget them, adapts to how hard each card is for you, and tracks your retention over time. The free plan is fully usable with no tricks.

How would you describe the primary audience of your product?

Space Repeat's answer:

Students who want to remember what they study for the long-term, especially those preparing for exams or learning large amounts of material over time.

What's the story behind your product?

Space Repeat's answer:

I'm a student myself. I tried the flashcard apps that already exist, but none of them felt right. Some were too flashy, packed with features I didn't need. Others were too bare-bones, with free plans so limited they were barely usable. I wanted something in the middle: a focused app that does a few things really well, with no distractions and a free plan you can actually use.

  • Anyone with a great idea how to use LLMs like GPT-3 to embed our Obsidian notes across applications?
    Eg https://get.mem.ai/ approach or https://beta.omnilabs.ai/ But then tailored to Obsidian. Source: over 3 years ago
  • Second Brain App recommendation
    I use Notion but I have heard that the andriod experience is not the best. You may want to try Coda, Obsidian, Mem or Anytype. I know of a few others but I think for the purpose of a second brain these can do the trick itโ€™s just about preference and which experience you like the most. Source: almost 4 years ago

    Https://get.mem.ai right now it isa web app they have an iOS app in beta. Source: about 4 years ago
  • Notion alternatives? (and what Iโ€™ve tested so far)
    For supervising the trauma team I've also been playing with "Mem". https://get.mem.ai/. Source: over 4 years ago
  • A second brain, for you, forever
    I really love obsidian. Sure I t has a couple of wrinkles, the mobile app is new still and has a couple more wrinkles, but it scratches so many itches I have around note taking. Currently using it alongside https://get.mem.ai/ and love the pairing for knowledge base and real time notes. Iโ€™m working from n combining the two to come up with my ideal set up. - Source: Hacker News / almost 5 years ago
