... and other love from our users
Memex seems to be, so far, exactly what i've been looking for. i was able to use it to prototype my dream note taking app in one morning. It's very impressive.
@IronPikachu
Out of all of them i tried. memex can build any app in any language. Its also great at reverse engineering android apps and making alternative versions with more functions than the original
@ConstantGlobal3961
[Memex] is becoming part of my team. From 5-minute tasks to 40-hour planning, development, and execution. It's starting to give me superpowers
Matt McQueen
Oh my god! You guys are the best so far in my experience. I've tried lovable, bolt, databutton, Rork, Base 44, and another one that YC is sponsoring, but it sucks. So believe me when I say you guys are the best! Keep up the great work!
James Sanders
Just found memex last night. Absolutely blown away so far. Ive tried to build this MVP on a number of tools and didnt even get close, if I did, design was not usable
Emile van Zyl
I just vibe coded a prototype for my engineers in 45 minutes that I could have never come close to doing on my own
