A better way for
Teams to use AI
An AI workspace for solving complex problems
Start solo today, invite your team when you're ready.
Explore multiple approaches in parallel with branching conversations
Current chat interfaces are linear
But problem-solving rarely follows a single straight line
You explore an approach, backtrack, try alternatives,
then continue from what works.
One Platform, All Models
Qasten replaces the scattered AI tools everyone currently uses on their own. Your whole team works in the same platform, while still using the models they prefer for each task. One shared workspace, all models, no more switching between apps.
Follow Every Idea with the Graph View
Qasten can display your chats as a graph canvas so you can trace every version, branch, and idea. It's easier to navigate and ideal when several people explore different directions at once. No more losing context in endless chat threads.
Multi-model Consensus for Smarter Answers
Qasten can run multiple models at once, have them challenge each other's outputs, and merge their arguments into a stronger answer. By comparing perspectives, consensus helps reduce hallucinations and delivers more reliable results when accuracy matters.
Security First, Always
Qasten is built with strict security from day one: EU-based hosting, and zero use of your data to train models. Learn more on our Security Page.
Deep Dives
Your Employees Are Smarter Than Your AI Policy
August 2025
Your employees are already breaking AI rules. Shadow AI is the clearest signal of where your workflows are broken and your biggest opportunities lie. You can fight it, or you can turn it into your unfair advantage.
Stop Treating AI like a commodity
July 2025
If you think cloud lock-in was bad, you're not ready for AI lock-in. Signing a multi-year deal with a provider is the fastest way to lose control of your AI strategy.
Frequently Asked Questions
Everything you need to know about Qasten.
How is Qasten different from ChatGPT?
ChatGPT is centered around a linear conversation history. Qasten makes it easier to work with multiple lines of thought over time by keeping different directions visible and easy to continue. This becomes especially useful when work involves several attempts or multiple people.
Which AI models are supported?
You can access all leading models like GPT-5.2, Claude 4.5, Gemini 3, Mistral, open-source models, and more. We believe in model neutrality, so you always have the right model for the right task. Learn more in our blog post.
How does Qasten guarantee data security and sovereignty?
Security is built in from day one. Qasten is hosted in the EU and guarantees your data is never used to train third-party models. Learn more on our Security Page.
How does Qasten help us move away from Shadow AI?
Shadow AI happens when internal tools are inexistent or restrictive. Qasten solves it by offering a platform that's more powerful than the tools employees use in secret. It wins them over by providing a superior experience. Read more about our approach in our blog post.
Do I need my whole team to use Qasten?
Not at all. Many users start individually to organize their own AI workflows and invite teammates later. It becomes even more powerful once teammates join and start collaborating.
