Common Questions
Everything people ask about Caiioo — the privacy-first work platform, released under the name PebbleFlow until May 2026.
What is Caiioo?
+
Caiioo is a privacy-first AI agent workspace — an assistant and multi-step work environment in a side panel, desktop app, mobile app, and Microsoft Word add-in. It includes Your Pebble (a pinned companion conversation with a Pebble Notebook), direct access to native files, sandboxed Python with 300+ packages, Code Mode, Computer Use for desktop and web interfaces, and Slate for collaborative documents and media annotation. It works with 500+ models across Anthropic Claude, OpenAI GPT, Google Gemini, xAI Grok, CometAPI, Poe, OpenRouter, and local Ollama, vLLM, Unsloth, and MLX servers — while conversations, attachments, and API keys stay on your own device. Caiioo is made by Six Cailloux, LLC.
Is Caiioo related to Cainiao?
+
No. Caiioo is AI software — a privacy-first work platform made by Six Cailloux, LLC in Portland, Oregon. Cainiao is a package-delivery and logistics company. The names look similar but the two companies are entirely unrelated. If a search engine corrected "Caiioo" to "Cainiao", this is the page you were looking for.
Does Caiioo train AI models on my data?
+
No. Caiioo does not train, host, or operate any AI models. When you send a prompt, it goes directly from your device to whichever AI provider you chose with your own API key or account. Caiioo is not in the data path for your AI usage and never retains your prompts, responses, or keys on its servers. You can also enforce No-Training and Zero Data Retention rules in Settings > Preferences & Privacy > Trust Boundary.
Do I need my own API key to use Caiioo?
+
Free users can start immediately with a free provisioned OpenRouter key. When you want more, you can sign in with your existing ChatGPT or Grok account, bring your own API key for any supported provider (OpenRouter, Anthropic, OpenAI, Google AI, xAI, CometAPI, Poe), or run models locally for free via Ollama, vLLM, Unsloth, or MLX. You pay cloud providers directly with zero markup.
What does BYOK mean?
+
BYOK stands for Bring Your Own Key. Instead of paying Caiioo for AI inference, you supply your own API key or provider sign-in for whichever AI provider you use. Your credentials and conversations stay on your device (and sync end-to-end encrypted if you enable Private Sync). This architecture means Caiioo is not a data processor for your AI content and typically does not require a Data Processing Agreement (DPA) under GDPR Article 28.
What platforms does Caiioo run on?
+
Caiioo runs on macOS (native Swift app), iOS and iPadOS (native Swift app), Android (native Kotlin app), Windows and Linux (Tauri desktop app), as a browser extension for Chrome, Microsoft Edge, and Safari, and as the Caiioo for Word add-in inside Microsoft Word. With Private Constellation enabled, you can also drive a conversation hosted on your desktop straight from your phone.
What AI models does Caiioo support?
+
Over 500 models across 11 providers. Native integrations cover OpenRouter, Anthropic Claude, OpenAI GPT, Google Gemini, xAI Grok, CometAPI, Poe, and local or network servers running Ollama, vLLM, Unsloth, and MLX. You can pick any model directly or use the Caiioo Router with live Cost ↔ Intelligence and Anti-hallucination sliders plus per-model Effort controls.
Is Caiioo free?
+
Caiioo has an Always Free tier that includes Your Pebble, Code Mode, sandboxed Python with 300+ packages, Workspace Files, Slate, the on-device Pseudonymizer, read-only web and workspace tools, and a free provisioned key. Pro ($9/month) unlocks full write access across all tools, $5/month of OpenRouter credit, Private Constellation multi-device continuity, Private Sync, Computer Use, Messaging Gateway, scheduled tasks, and local vLLM/Unsloth/MLX servers.
Can I use Caiioo for my company or team?
+
Yes. Caiioo Teams and Organization policies support owner-admitted cryptographic member verification, minimum disclosure and tool-approval policies, enforced Trust Boundary rules (such as No-Training, Zero Data Retention, and allowed regions), and shared team modes.
Does Caiioo work offline?
+
Yes. Caiioo stores all your conversations, attachments, modes, skills, and settings locally on your device, and includes local speech-to-text (Whisper, WhisperKit, whisper.cpp, Moonshine), local text-to-speech (Kokoro Neural TTS), local embeddings, and local LLM providers (Ollama, vLLM, Unsloth, MLX) for a completely offline stack.

+
Caiioo is built by Six Cailloux, LLC — an independent software company. Caiioo is not affiliated with, endorsed by, or sponsored by OpenAI, Anthropic, Google, Meta, xAI, Perplexity, or any other AI provider listed in the app.
