Every frontier model, one subscription
One AI subscription for your whole team
GPT, Claude, Gemini, and every other frontier model in one workspace. Shared chats, your own documents, one bill. From $20 a seat.
Claude 4.5
GPT-5
Gemini ProEvery major lab, in one workspace
Everything the four subscriptions did
Consolidating shouldn't mean giving things up. The work your team already does across four tabs happens in one place in Langkast.
Can you rewrite this section in Claude instead? GPT's draft is close but the tone is off.
Every model, one chat
Switch between GPT, Claude and Gemini mid-conversation without losing the thread. No tab-hopping, no re-explaining context.
Answers from your own documents
Upload the handbook, the contracts, the spec. Ask questions and get answers that cite the source rather than guessing.
Usage you can actually see
Your balance is on screen, not buried in a settings page. No silent throttling, no guessing what a message costs.
Agents for recurring work
Turn the prompt you retype every Monday into something that runs itself, and share it with the team.
Most teams pay four vendors for overlapping access to the same handful of models. That is about $80 per person per month, and $20 here.
List prices per person, per month. Compare against your own invoices; your mix may differ.
Live in an afternoon
No procurement cycle, no rollout plan, no sales call. Four steps and the team has moved.
Built to not lock you in
Consolidating onto one vendor is only a good trade if leaving stays easy.
Your data stays yours
Your conversations and documents aren't used to train models. Export everything and cancel whenever, with no annual commitment.
Model agnostic
New frontier models show up here as the labs ship them. You aren't betting the team on one lab's roadmap.
