Launching today
Krater turns AI from something you try into something you use. Every AI model, every modality, every app you use, combined into one chat and driven by one agent. Tell it what you need in plain language and it gets it done; whatever you're building, studying, running or creating. The same agent that chats with you can generate an image, edit a video, produce a song, automate your apps, and publish a full website, all in one flow. 70K+ users. API access. Replaces $100+/mo in subscriptions.

Four years ago I started building Krater alone, on the side, as a copywriting app with templates powered by an early GPT model. That was it. Output quality was rough, but it was the first time AI felt useful to me, so I kept going.
I'm Malte, the founder. As the technology got better, the product grew with it. I added text to speech, then image generation, then video, then more models from every major provider as they came out. Every step was driven by user feedback and what was suddenly possible that month. You can actually see the journey in the older Krater launches below this one, going all the way back to 2023. Since the start of 2026 there have been four of us full time, and we've spent the year rebuilding everything around one realisation:
The problem with AI isn't the models. It's the gap between trying AI and actually using it. People sign up to ChatGPT, get impressed, and a week later they're back to doing things the old way, because using AI well means juggling five tools that don't talk to each other.
Krater is still the place where every AI model from every provider lives in one app. What's new is the agent on top of them. It uses every model and your connected apps to actually finish the task, and it can run on a schedule so the work keeps happening without you. Research goes into your Notion every Monday morning. Images land in a website it just published. A daily summary of your inbox waits for you at 8am. Same chat box, completely different product.
70,000+ people use it today. The description and images above covers what it does. What I'd actually love from you: tell me the task you keep avoiding because AI almost helps but not quite. That's what we're building toward next.

Four years building one problem — that's how you hit 70K users. What kills retention most — habit pulling people back to ChatGPT, or missing features?
Krater
Yes it was @nelly_orlova! Great question: We generally implement new features based on feedback within a few days. So not that. The data is a bit blurry on why people leave – but we commonly see people staying that get the platform and tries it out for a few hours, they see the power. What kills retention is if people don't get their "Aha" moment fast enough, so we're on that as well :)

Do you let people pick and pin their preferred models per task, or does the agent auto choose everything?
Krater
Of course @thamibenjelloun! You've got both options: Choose from 350 different AI models (we carry ALL you can think of) manually, or you can pick one of our "Auto Routers" that picks the model based on your prompt.
Damn guys! This is some amazing work, seems like something sorely needed in a market of cheap AI rip-offs. Something thoughtfully put together with a real purpose beyond just gobbling up people's money!
What are the current limitations of your services, and is there any such one that's harder to improve than others?
I'm not all too technically gifted but I would love to know more. I'll be giving Krater a good run to learn more about how it works, looking forward to using your services!
Krater
Thanks a ton for your comprehensive comment and your kind words @albin_ullstrom!
There actually isn't really a limitation so to speak, I would more say that comprehensive features like our /build slash command that builds and publishes websites are more tricky to implement, as they need to not clutter anything and work as people expect it to :)
Let me know how you like Krater! We're always here to help and listen to any feedback.
I have been using Krater for a little over 3 months now and i love it. It feels very intuitive even for non AI users with it’s simple / commands. But also has features like API, Teams and Tasks for when you start learning more. So there is always something to unfold.
As of now i use krater daily. Mainly just for chats but also to get my news and email briefs with my morning coffee!
Amazing product
Krater
Thanks a ton for your comment @elin_gustafsson1 ! We're delighted that you love Krater 🙏🏼
Curious about silent failure. If a Monday research run quietly drops a garbage summary into Notion four weeks running before anyone checks, what catches it? All in all I think the scheduled-agent piece is the wedge here. Congrats on launching a decent product!

Hey guys, thank you so much for checking out our launch! It means the world to us.
