About Chapeta
Chapeta is a native Mac AI assistant that lives in your menu bar. It gives you instant access to the best AI models and 9 executable tools from one keyboard shortcut, without leaving the app you're working in.
Why It Exists
Most AI tools run in a browser tab. You switch apps, type a question, copy the answer back, and try to pick up where you left off. That context switch costs more than a few seconds. It breaks the thread you were holding.
On top of that, the best model for the job changes by task. Claude for code. GPT for prose. Gemini for search. DeepSeek for reasoning. Paying for three separate subscriptions just to cover different jobs is expensive and fragmented.
Chapeta exists to solve both problems: bring AI to your current window instead of pulling you away from it, and give you every major model in one place so you can pick the right one without switching apps.
Who Built It
Chapeta is built and maintained by Sagi Hammer, an independent developer. It's a solo project, no VC funding, no growth team, no enterprise sales pipeline. The product improves because one person uses it every day and fixes what's broken.
The codebase is native Swift (SwiftUI + AppKit), built specifically for macOS. It uses Apple's own frameworks for security (Keychain), voice input (SFSpeechRecognizer), and system integration rather than wrapping a web page in Electron.
Principles
Native Mac, Not a Web Wrapper
Chapeta is built with SwiftUI and AppKit. It uses macOS APIs directly: Keychain for secrets, SFSpeechRecognizer for voice, and native file, screenshot, and windowing APIs. No Electron. No browser hidden behind a frame.
Privacy by Architecture
Conversations are stored locally on your Mac. API keys live in macOS Keychain. Email sign-in only - no passwords or social logins. There are no ad trackers or in-app tracking SDKs.
No Provider Lock-in
Chapeta connects to 300+ models from 50+ providers through OpenRouter. You pick the model that fits the task. If a better model launches tomorrow, you can use it the same day.
Tools That Act, Not Just Talk
9 tools help you finish real work on your Mac: terminal commands, file operations, web search with citations, and screenshot analysis. You stay in control of what the AI can and cannot do.
The Numbers
300+ AI models from 50+ providers. 9 executable tools. 15 built-in skills. 8 themes. Runs on Apple Silicon or Intel Mac with macOS 14+. See the full breakdown on the numbers page.
