PromptBar native streaming chat window on macOS

Streaming from gpt-4o

What's inside

Built to disappear until you need it.

PromptBar ships empty. No bundled providers, no bundled brands. You decide what goes in the menubar, and the app stays out of your way.

Liquid Glass UI

Top-to-bottom on macOS 26's material system. Sits perfectly beside every native app.

Wrap any web chat

Paste a URL, pick a name, icon, and color. Cookies live on this Mac, not in the cloud.

BYO API key

OpenAI-compatible /chat/completions. Straight from your Mac to your endpoint. No relay.

Prompt library

Save your best prompts once. Reuse in any chat with ⌘ P. Search, tag, ship.

Keychain-backed keys

Not in UserDefaults. Not in iCloud. Not in a log file. Just the Keychain.

Zero telemetry

No accounts. No analytics. No remote config. Updates check GitHub directly.

Look inside

One popover. Every conversation.

Native streaming chat, web-wrapped chats, API endpoints, MCP servers, and a keyboard-driven prompt library.

PromptBar Web Chats settings, wrap any URL

Bring your own key

Point PromptBar at any OpenAI-compatible endpoint.

The de-facto standard, supported by the vast majority of inference services and local runtimes. If it speaks /chat/completions, PromptBar can chat with it.

Native streaming with server-sent events, cancel mid-stream.
Base URL, model, key, and system prompt persisted per endpoint.
Straight from your Mac to your endpoint, no relay, no middleman.

endpoint.json

// Configured once, saved to Keychain
{
  "name": "My OpenAI",
  "baseURL": "https://api.openai.com/v1",
  "model": "gpt-4o-mini",
  "apiKey": "* stored in macOS Keychain *",
  "stream": true,
  "systemPrompt": "You are..."
}

Private by design

No accounts. No analytics. No telemetry.

PromptBar was rebuilt from the ground up around a single rule: your data leaves your Mac only when you send it, only to where you send it.

Keychain-backed keys

Not in UserDefaults. Not in iCloud. Not in a log file.

Local cookies

Web chats run inside WKWebView. Clear all local data with one click.

Zero remote config

Firebase is gone for good. Updates check GitHub Releases directly.
