Works with the world's leading AI models.

Everything you need to work with AI.<br>Six things that used to live in six places, in the one place you work.

Can you rewrite this section in Claude instead? GPT's draft is close but the tone is off.

Work with every leading model.<br>Ask one question and answer it with whichever model is best for it. Switch mid-conversation without losing the thread or opening a tab.

Delegate repetitive work to AI.<br>Turn the prompt you retype every Monday into an agent that runs itself. Agents live in the workspace, so everyone gets the version that works.

Source: handbook.pdf, p.12

Keep everything in one place.<br>The handbook, the contracts, the spec — uploaded once and answered against, with every answer pointing back at the page it came from.

Work with the tools you already use.<br>Connect the apps your work already lives in, so you act on the data where it is instead of copying it across by hand.

Let recurring work run itself.<br>Set the weekly digest and the inbox triage running on a schedule. They happen without anyone remembering to start them.

The problem isn't access to AI. It's that your AI work is scattered.<br>People run ChatGPT in one tab, Claude in another, Gemini for research, and keep the documents, prompts and workflows somewhere else again. Langkast brings all of it together in one workspace.

Stop switching. Start working.<br>Whether you work alone or with a small team, one place means less time finding things and more time doing the work.

Stop switching between AI tools

Keep every conversation, prompt and project organized

Build reusable workflows instead of repeating work

Stay focused in one workspace

Stop switching between AI tools<br>Every model, agent and document is in the same place. No hunting for the tab where you left the thread.

Keep every conversation, prompt and project organized<br>The work stays together in the workspace instead of scattering across products, so you can find it again next week.

Build reusable workflows instead of repeating work<br>The process you worked out once becomes something you can run again, and hand to someone else.

Stay focused in one workspace<br>Less time re-explaining context, re-finding prompts and re-uploading the same file. More time on the work itself.

Private by default. Yours forever.<br>Putting everything in one place is only a good trade if the place is one you can leave.

Your work belongs to you<br>Your conversations, your documents and your workflows stay yours. None of it is used to train models, and you can export all of it and leave whenever you want.

Never locked to one model<br>Switch models whenever you want, mid-conversation if you like. New ones appear in your workspace as the labs ship them, so you aren't betting your work on one roadmap.

Questions<br>The things people ask before they move their work.

Is this another chatbot?

Do I lose access to the models I already like?

What happens when a new model comes out?

Can I use my company's documents?

Which tools can I connect?

Is my data used for training?
