Deploy Kyubi on-premise so screen captures never leave your network. Set org-wide policies for which applications Kyubi can observe, with a full audit log. Contracts include SSO, SCIM and volume token pricing on a single invoice.
Run the full Kyubi stack on your own infrastructure. Air-gapped installs are available for regulated environments where screen data cannot touch external networks.
Your cloud API requests route through isolated infrastructure with a guaranteed throughput SLA. No shared tenancy, no data co-mingling.
Define org-wide policies for which apps and windows Kyubi may capture, with a full audit log of every screen-context request.
One set of provider API keys for your whole org, with per-team and per-user spend limits.
SAML 2.0 / OIDC single sign-on and automated user provisioning via SCIM. Works with Okta, Entra and Google Workspace.
Commit to token volumes at discounted rates, unified across all cloud providers on a single invoice.
05 — Questions
Never. With a local model, screen captures are processed on your device and never saved to Kyubi's servers. With a cloud model, the capture goes straight to the model and is then deleted; Kyubi does not keep a copy.
Kyubi captures the active window or a selected region, sends it to a local vision model (LLaVA 1.6 or Moondream 2) running entirely on your machine, and the model replies. No internet connection is required and no data ever leaves your device.
Cloud model providers (OpenAI, Anthropic, Google, etc.) charge per token, roughly per word processed. When you send a message or a screen capture to a cloud model in Kyubi, the cost is deducted from your credit balance. Included credits refresh each billing period. You can top up manually at any time and those credits never expire.
Included monthly credits do not roll over; they reset each billing period. Manually purchased top-up credits are permanent and never expire. Kyubi always draws from your included credits first before touching your top-up balance.
Any model compatible with Ollama or llama.cpp. Hardware is the main constraint: larger models need more VRAM or Apple unified memory, so check compatibility first.
No, we use proprietary infrastructure and do not support bringing your own API keys for cloud providers.
Cloud model requests will be paused until you top up or your next billing period begins. Local models and on-device screen reading are completely unaffected and will keep running regardless of your credit balance.
Yes. Upgrades take effect immediately and are prorated. Downgrades apply at the end of the current billing period so you keep your current features until then.

About — Kyubi
Most AI is built to do the work for you. Kyubi works with you, then steps aside.
01 — Why
AI has shown huge promise, and it is often misused. While companies race to put it in everything, we asked a different question: how can AI make people better at their own work?
Kyubi is our answer. Ask it for help with menus, unfamiliar software, or a second look at your work, and it answers in place, on your screen, in the workflow you already have. The idea is simple: amplify people with AI, do not replace them.
02 — Values
We look for practical uses for AI. If we use a technology, it is the best fit for the job.
Kyubi is built from the ground up with industry standards in mind and is compliant with all major data protection regulations.
We believe in pushing AI forward, and in making that power accessible.
We make software that is built for the future.
