Capabilities

Discover the integrated tools, extensibility options, and AI orchestration that power the caiioo platform-in-extension.

What caiioo does

A reference overview of every caiioo capability, with links to the user-guide page where each is documented in depth.

Any AI provider — bring your own key

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

Agentic tools and MCP extensibility

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

Slate — a collaborative canvas for code and documents

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 — reusable AI personalities

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 — reusable prompts and workflows

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

Voice input and output

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

Personalization variables

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

Privacy-first architecture (BYOK, local-first)

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

Private sync across your devices

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

Cross-platform native apps and extensions

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

Public REST API

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

Why caiioo?

Seamless AI Switching

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.

Your Data and Personalization Stays Yours

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.

gmaildrivedocssheetscalendargemini

Deep Google Workspace Integration

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.

No Hidden Throttling

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.

Discover New Use Cases Daily

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.

Built-in Ad Blocking

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.

Dial In What Works—or Ask the AI to Design an Agent

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.

Custom Modes

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.

Skills

Save effective prompt patterns as reusable skills. One click replays a proven workflow instead of rewriting prompts from scratch.

Page Learning

Teach your agent about specific websites and apps. caiioo remembers how to navigate your tools so the AI gets smarter with every interaction.

Custom Variables

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 Canvas That Handles Everything

Common Questions

Everything people ask about caiioo — the AI context management app, not the recreational travel trailer.

What is caiioo?

caiioo is a privacy-first, bring-your-own-key (BYOK) AI context management app and browser extension. It lets you run agentic AI workflows with any major model provider — Anthropic Claude, OpenAI GPT, Google Gemini, xAI Grok, Mistral, Perplexity, Meta Llama, local Ollama, OpenRouter, and 500+ more — while conversations, attachments, and API keys stay on your own device. caiioo is made by Six Cailloux, LLC.

Is caiioo the same as the Pebble Flow travel trailer?

No. caiioo (one word) is software — specifically, an AI context management application and browser extension made by Six Cailloux, LLC. It has no affiliation with the Pebble Flow (two words) recreational travel trailer or its manufacturer. The two products are entirely unrelated.

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. caiioo is not in the data path for your AI usage and never retains your prompts, responses, or keys on its servers.

Do I need my own API key to use caiioo?

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.

What does BYOK mean?

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.

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), and as a browser extension for Chrome, Microsoft Edge, and Safari.

What AI models does caiioo support?

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.

Is caiioo free?

caiioo has a free tier with access to built-in tools and a limited number of free-model messages via OpenRouter. Paid plans (Pro, Platform, Teams) 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.

Can I use caiioo for my company or team?

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.

Does caiioo work offline?

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.

Who makes caiioo?

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.
