Caiioo works with every major AI provider. Add keys for Anthropic Claude, OpenAI GPT, Google Gemini, xAI Grok, Mistral, Perplexity, Meta Llama, local Ollama, or OpenRouter (which brokers 500+ models under a single key). Switch models mid-conversation without losing context. You pay the provider directly — Caiioo never brokers, proxies, or marks up tokens.
Provider setup guide →Caiioo ships with built-in tools for web browsing, AI-powered web search, Google Workspace (Gmail, Drive, Calendar, Docs, Sheets, Slides), image generation, calculations, and more. Any Model Context Protocol (MCP) server extends the tool palette without code changes. Any tool that can write, modify, send, or delete data requires explicit approval by default; read-only tools run without interruption. Every tool call — read-only or not — produces an auditable trail.
Tools guide →Caiioo works directly in your files and code. Through the desktop app it reads, edits, and patches files in place, searches whole folders, runs shell commands in a sandbox, and uses language-server intelligence to find real definitions and references rather than text matches. Your files stay where they live — nothing is copied into a second store.
Tools guide →Caiioo can operate desktop applications and web interfaces the way you do: reading the screen, clicking, and typing — always with your permission and under your supervision, with approval controls on every action. Rolling out now on desktop.
Tools guide →Slate is Caiioo's built-in editor that combines a Monaco code editor with a TipTap rich-text surface. The AI writes and edits artifacts directly in Slate; you review, revise, and accept changes without copying and pasting between apps. Artifacts persist across threads and sync to whichever device you're working on.
Slate guide →Modes are pre-configured personalities with their own system prompt, default model, tool selection, and UI. Caiioo ships with General, Workplace, and LuxDeal modes, and you can author your own. Teams can publish locked modes to enforce consistent AI behavior across every member without governance policies being bypassed.
Modes guide →Skills are saved prompt templates and multi-step workflows. Invoke them from a command palette to run a recurring task — a weekly report, a code review rubric, a translation workflow — without rewriting the same prompt every time.
Skills guide →Caiioo supports speech-to-text dictation and text-to-speech output across every platform, with configurable voices and languages. Push-to-talk and hands-free modes are both supported.
Voice guide →Variables inject user context — your name, role, expertise, preferences, active project — into every prompt automatically. Variables are scoped per-mode or globally, and custom variables can be defined by the user or the workspace admin.
Variables guide →Conversations, attachments, API keys, and tool configurations are stored on your device by default. Caiioo is not an AI data processor: we never see your prompts, responses, or keys. No DPA is typically required for enterprise adoption because Caiioo does not process personal data on your behalf under GDPR Article 28.
Privacy & data guide →Optional end-to-end encrypted sync keeps conversations, modes, skills, and settings consistent across macOS, iOS, Windows, Linux, Android, and your browsers. Keys stay on your devices — the sync server never decrypts your data.
Private sync guide →Caiioo is available as a Chrome extension, Edge extension, Safari extension, a native macOS and iOS app (with EventKit integration), a native Android app (with CalendarContract integration), and a Tauri-based desktop app for Windows and Linux. Settings and threads move with you.
Platform guide →The Caiioo public API lets other applications query threads, invoke skills, and access user-approved tools programmatically. Every request is authenticated per-user and subject to the same local-first, BYOK boundaries as the apps.
Public API guide →Switch between Claude, GPT, Gemini, Grok, Llama, Mistral, and Perplexity mid-conversation. Your preferences and context carry over—no vendor lock-in. New models available within hours of release.
True Privacy and Security By Design and Default. Conversations, settings, and personalization stored locally. When your conversations generate insights about you and how you work, they're yours—stored on your device, ready to use with any AI model. No personalization lock-in. Data retention policies are clearly marked so you choose—and most responsible providers offer zero data retention through APIs that you now get to easily use.
Caiioo connects directly to your Google Workspace. Search and summarize emails, find files in Drive, read and write Docs, analyze and update Sheets, manage Calendar events—all through natural conversation. Use Caiioo alongside or instead of Google's native AI features, ensuring you benefit from improvements to Google's services while enjoying Caiioo's versatility across any AI model.
Other AI apps silently truncate your context to save costs. With Caiioo, every piece of information you add is considered by the AI—not summarized until the model's full capability is used. The result: better attention to detail, fewer hallucinations, and less forgetting. Smart design reduces your costs without any loss.
A growing platform of tools that combine in powerful ways: spreadsheet to personalized emails, photos to illustrated stories in Slate, web research to polished first drafts, knowledge bases to instant answers. New capabilities added constantly—the combinations are endless.
Stop wasting tokens and AI thinking on ad content. Caiioo's built-in ad blocking removes ads before they reach your AI, keeping conversations focused on what matters. Need ads included? Toggle it off anytime.
Just tell Caiioo "Make me an agent that..." and it builds one for you—a custom mode with its own system prompt, preferred tools, and personalized context variables. Refine it yourself or keep prompting the AI to iterate. The result: reusable agents that produce consistently better results with higher accuracy.
Create specialized AI agents with their own personality, tools, and context. A support agent, a writing coach, a code reviewer—each tuned to its task.
Save effective prompt patterns as reusable skills. One click replays a proven workflow instead of rewriting prompts from scratch.
Teach your agent about specific websites and apps. Caiioo remembers how to navigate your tools so the AI gets smarter with every interaction.
Define dynamic parameters—your name, project details, client info—that auto-inject into every prompt. The same agent adapts to different contexts without manual editing.
The AI's blank canvas — virtually unlimited creative potential
Slate is where human and AI creativity merge. More than an editor — it's a runtime for co-creation. Start an idea and let AI finish it. Or let AI generate a draft and refine it yourself. Iterate back and forth on documents, code, websites, interactive games, and data visualizations. Everything runs live in your browser.
Process PDFs with OCR, parse Word docs with tracked changes and comments, extract data from spreadsheets.
Have AI check your writing and suggest edits you can see and accept transparently. Handle redlines and comments in Word docs—even suggesting responsive edits.
Full syntax highlighting for any programming language. Write documentation, README files, or technical specs with AI help.
Create website and web app mockups and edit them on the fly. Preview HTML and iterate with AI suggestions.
Whatever the AI can imagine, it can build and show you instantly.

What happens: Searches for highly-rated gifts in those categories, checks current prices and availability, reads reviews, and presents a ranked list with pros/cons. Opens product pages in grouped tabs so you can browse and buy easily.
“Are raisins okay for dogs? Please research and cite sources to credible articles so I can verify. Then save a list of common toxic foods to my notes so I don't forget.”
What happens: Uses Perplexity deep research to find veterinary sources, academic studies, and trusted pet health organizations. Returns a clear answer with inline citations linking to the original sources—ASPCA, veterinary journals, poison control databases—so you can verify the information yourself. Then compiles a quick-reference list of common toxic foods for dogs and saves it to Apple Notes for easy access later.
“Does my health insurance cover physical therapy? I need to understand my coverage before booking an appointment.”
What happens: First uses Perplexity to research how insurance typically handles PT coverage—common limits, pre-authorization requirements, in-network vs out-of-network rules. Then navigates to your insurance portal (you're already logged in via saved session), finds your specific plan details, checks your remaining deductible, and summarizes your actual coverage limits and any steps needed before your first visit.
Seamlessly coordinate when life and work collide
“My partner asked when I can go to the mountains with them, but I have a weekend meeting coming up and several things to finish. Check all my calendars, find a few available times I can text them, then block those off so I don't get double-booked.”
What happens: Queries both your work and personal calendars (Google, Apple) to understand your full schedule. Identifies conflicts and commitments across all sources. Finds windows that work around your obligations, formats them nicely for texting, and creates placeholder events to protect your availability.
“I need to schedule a dentist appointment—they're only open weekdays 9-5. When am I actually free for an hour?”
What happens: Checks your work calendar for meetings, your personal calendar for commitments, and finds genuine gaps during business hours. Accounts for commute time and buffer between meetings. Presents options ranked by convenience.
“My kid's school play is Thursday at 2pm. Make sure I don't schedule anything that conflicts and remind me to leave by 1:30.”
What happens: Creates a blocking event on your work calendar, sets up a Caiioo reminder for departure time with desktop notification, and can even draft an out-of-office message for that window if needed.
“I'm taking PTO next Friday through the following Wednesday. Block it everywhere.”
What happens: Creates all-day events across your work and personal calendars, marks you as unavailable, accounts for time zones, and adds reminders to prep handoffs before you leave.

Everything people ask about Caiioo — the privacy-first work platform, released under the name PebbleFlow until May 2026.
Caiioo is a powerful, privacy-first work platform — an agentic assistant and chat in a side panel, with direct access to native files through its desktop app, Computer Use for desktop and web interfaces, and native access to the live web. It works with any major AI provider — Anthropic Claude, OpenAI GPT, Google Gemini, xAI Grok, Mistral, Perplexity, Meta Llama, local Ollama, OpenRouter, and hundreds more — while conversations, attachments, and API keys stay on your own device. Caiioo is made by Six Cailloux, LLC.
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.
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. Caiioo is not in the data path for your AI usage and never retains your prompts, responses, or keys on its servers.
Free users can try Caiioo with a limited free tier via OpenRouter. For production use, you bring your own API key for whichever provider you prefer (Anthropic, OpenAI, Google, xAI, Mistral, Perplexity, OpenRouter, local Ollama, or any other supported provider). You pay the provider directly — Caiioo does not mark up token costs.
BYOK stands for Bring Your Own Key. Instead of paying Caiioo for AI inference, you supply your own API key for whichever AI provider you use. Your key and your conversations never leave your device. 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.
Caiioo runs on macOS (native Swift app), iOS and iPadOS (native Swift app), Android (native Kotlin app), Windows and Linux (Tauri desktop app), and as a browser extension for Chrome, Microsoft Edge, and Safari.
Any model exposed by any supported provider. Native integrations cover Anthropic Claude, OpenAI GPT, Google Gemini, xAI Grok, Mistral, Perplexity, Meta Llama, and local Ollama. Connecting OpenRouter gives access to 500+ additional models under a single key. Caiioo adds new models to its UI within hours of release.
Caiioo has a free tier with access to built-in tools and a limited number of free-model messages via OpenRouter. Paid plans (Pro, Teams, Enterprise) unlock premium tools, higher limits, and team features. Because Caiioo is BYOK, the token cost of AI usage is separate and paid to whichever AI provider you choose.
Yes. Caiioo Teams provides centralized billing, admin-published modes with locked configurations, and seat management. Because the BYOK architecture means Caiioo is not a data processor for AI content, enterprise adoption typically does not require a DPA, SOC 2 Type II prerequisite, or GDPR Article 28 obligations against Caiioo itself.
Partially. Caiioo stores all your conversations, attachments, modes, and settings locally, so you can browse your history offline. For live AI inference you need a connection to your chosen AI provider, unless you use a local provider like Ollama — in which case Caiioo works fully offline.
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.
