Where Calliope Fits

For work that has to be defended.

Move a decision

When the room has to choose a path, approve a risk, fund a plan, change a policy, or commit scarce resources.

Prove a case

When a claim must survive hostile reading: evidence, source order, counterarguments, and the burden of proof all matter.

Teach a hard idea

When complex material has to become clear without becoming shallow: doctrine, data, science, policy, strategy, or belief.

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 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.

Where Calliope Sits

Different tools, different jobs.

Most AI presentation tools fill a template with text. Calliope and Gemini Notebook draw each slide as an image, so there is no template to escape: any layout, any style, a visual built for the point you are making. Calliope adds PromptCoach, which turns your material into a storyboard before a slide is drawn, and a data posture fit for a pitch book, a board paper or a deal memo. Public documentation, enterprise tiers included, verified August 2026.

Enterprise tiers carry stronger data terms than consumer defaults; we show both. Every tool here is good at its job. Calliope's is narrow: image-drawn slides for a message that matters, from material that must stay private.

If your material is not confidential and a template will do, several of these tools will serve you well and cost less. Calliope is priced for the other case.

Pricing and Deployment

Not for every deck. Built for the ones that matter.

  1. The Basis

    Priced for the stakes, not the volume

    Calliope is priced for the stakes of the work it carries, not to chase volume. We don't subsidize slide counts to win sign-ups; the price reflects the real reasoning, extraction, and assembly behind every deck.

  2. As a Service

    Sign up and start today

    Register and run Calliope on our managed, privacy-first cloud. Every new account starts with credits for real work, no payment needed. We built Calliope as a test bed for professional and demanding users, and we gladly grant more credits for legitimate professional exploration. Just ask.

  3. Private Cloud

    A machine that's yours alone

    Prefer isolation? We stand up a dedicated instance for your exclusive use, on Google or Microsoft. We chose those two for the widest data-sovereignty options; AWS is under consideration. Contact us and we'll arrange it.

  4. Private Deployment

    Behind your own firewall

    For full control, we bring Calliope to your own infrastructure with a white-glove deployment, handled end to end. Contact us to plan the rollout.
