Agentic Operation

It works inside the AI you already use.

Give Calliope the goal and it reads, structures, composes, and revises the deck on its own, with you in control. It works inside the AI you already use: connect it to Claude or another major assistant, and the tool that reasons with you can finally hand over the finished presentation it could never build alone.

Works inside ClaudeDrive Calliope from the Claude conversation you're already in. No new app, no export, no lost context.
Sharpens the askPromptCoach turns a loose request into a precise brief, so the first draft lands closer to done.
Builds the presentationFrom brief to finished slides: structured, sourced, and rendered in full fidelity, then open to edit.
— Privacy
Privacy Architecture

Lawful distance, not secrecy theater.

Calliope is built for confidential source material: the documents you cannot pass around. Privacy here is structure, not a slogan. Your files are read inside Swiss and EU confidential-computing infrastructure, used only to build your deck, then deleted. They train nothing. And because Calliope is operated by an Indonesian company, accountability has a real address.

Where your files are processedSwiss and EU infrastructure on Google Vertex AI. Your documents are read in-region and never leave it.
TrainingNever. Your files, prompts, and finished decks are not used to train any model, ours or a provider's.
RetentionSource files are deleted after processing. Delete means gone: keys are destroyed, so recovery is impossible, including for us.
Operator accessZero admin knowledge. The system is built so our staff cannot read your content.
ProcessingEphemeral: no content caching, no content logging, and working memory cleared the moment a job ends.
Confidential computingWorkloads run on AMD SEV hardware with encrypted memory, protected even from the server they run on.
Who is accountablePT Karya Nyata Teknologi, a company registered in Indonesia (Electronic System Provider No. 060226003711500050001).

Switzerland and Indonesia cooperate through formal legal-assistance channels. The point is not to put your data beyond the law. It is to put it under good law, with a named operator answerable for it.

  1. The Basis

    Priced for the stakes, not the volume
