SoulLink - Mobile 3D Vibe Coding Partner

๐๐จ๐ฎ๐ฅ๐๐ข๐ง๐ค lets you build a cozy life with an awesome 3D AI character during the breaks of vibe coding. It is the next-gen companion app built for co-presence with best-in-class 3D visuals, novel-depth lore, emotional continuity, proactivity and long-term memory.

The user flow is intuitive, and personalization settings give users enough control over their companionโs personality and appearance. That said, thereโs still room to optimize scene diversity and long-term user stickiness mechanisms. Overall, SoulLink delivers a polished, emotionally resonant AI companion experience with strong product maturity. Itโs definitely a benchmark for 3D AI companion apps worth learning from.

This is an interesting take. Iโve definitely noticed those small gaps while AI is generating โ I usually end up drifting to other apps without realizing it. Not sure if Iโd use a companion for that yet, but the idea of something lightweight that doesnโt break flow is appealing. Curious to see how this evolves.

@alexia_liย thank you for sharing you work on the same rhythm! but im truly curious what you'd actually do during those time. it's too short to do anything meaningful and too long to stay engaged for many.
Really love the ambient companion ideaโitโs like being tucked away in a cozy cave where you can stay in the zone and feel safe while you work.

@limin_ge1ย you are describing exactly what we want to build towards! my way of describing is this: late spring afternoon, teenage, sunlights in the room, you and your best friend, chilling in your living room by yourself, drinking cold soda, and share some random thoughts and laugh about it together. it's the most beautiful category of companionship that I can possibly imagine.
Iโd love multiplayer or shared companion spaces with friends or teammates down the line. Congrats on launching today.

@zerotoxย hey kumar what's up! haha yeah our current thesis as a startup is to put 100x effort into one single character and see how far we can push game+ai tech to simulate a real life. multiplayer is gonna be really fun down the road but the tradeoff between quality and quantity is real. i have little doubt we will see it relatively soon though!

How customizable are these companions going to be?
SoulLink
@nuseir_yassin1ย a great great great questions. this is also something that we think hard and innovate. our core thesis is around we build the most awesome character possible and her core will stay strong, consistent and unshakable(like a real person). where do we draw the line of customization? well, anything in real life that we can influence on another person, we should allow that to happen in a ai-to-human relationship. So her outfit, habit, and even some reactionary hebavior will gradually be influenced by you over time.

Congrats on launching. This is quite innovative. Any plans of installing Soullink into a real-life robot?
SoulLink
@roopreddyย ahh greattt point. we actually get that a lot, but based on current state of humanoid robot, we feel like adding the physical part will actually significantly increase the uncanny valley, logistics cost, price(therefore size of audience) and physical/ethical danger it poses to our society. staying purely software should be the way to go!

This feels like a new category rather than just another AI app. Well done. Congrats!!!
SoulLink
@syed_shayanur_rahmanย it's absolutely a new category! otherwise it wouldn't justify all the retentless effort we've put into it! it doesn't feel like we are building software, i'd bet building small rockets aren't much more complex than building a virtual human!
Can it motivate me?
Congrats on the launch!
I previously released a UGC-based AI Friends app in China, but at the time, we didn't focus as much on building out a PGC world and dedicated scenes. It's really inspiring to see @michael_shang and the SoulLink team taking this approach. There are so many possibilities for social interaction and emotional bonds between humans and AI. Excited to let 4D lead the way!
Congrats on the launch, interested to see if the memory persists.
