📨 GizTUI - AI-Powered Gmail Terminal Client

A powerful terminal Gmail client built in Go that brings AI intelligence to your email workflow. Features local AI integration, advanced productivity tools, and seamless integrations with Slack, Obsidian, and more.

✨ Key Features

📬 Complete Gmail Management

• Full email operations: compose, reply, forward, archive, search, and label management
• Advanced threading with conversation grouping and AI summaries
• VIM-style navigation and bulk operations (d3d to delete 3, a5a to archive 5)
• Powerful Gmail search with filters, date ranges, and size-based queries

🧠 AI-Powered Intelligence

• Email summarization with streaming support (Ollama & Amazon Bedrock)
• Smart label suggestions based on email content
• Custom prompt library with variable substitution and bulk analysis
• Local caching to avoid re-processing with SQLite storage

⚡ Deterministic rules (no AI)

• :rules — manage query → action rules (archive, trash, label, mark read, prompt) stored locally
• :rules plan — preview what your rules match as an Action Plan, instantly, no AI involved
• With inbox_analyzer.deterministic_prefilter enabled (default), the AI Inbox Action Plan resolves rule matches first (marked ⚡) and only sends the remaining emails to the LLM
• :rules sync <n> mirrors a rule as a real server-side Gmail filter (marked ☁); :rules unsync <n> removes the mirror

Note: mirroring rules to Gmail needs the gmail.settings.basic OAuth scope, added in this version. Existing installs must re-authenticate once (delete the token file, e.g. ~/.config/giztui/token.json, and restart) before :rules sync works. Everything else keeps working with the old token.

🔌 Seamless Integrations

• Slack forwarding - Send emails to configured channels with AI summaries
• Obsidian ingestion - Transform emails into structured markdown notes (individual files or combined repopack)
• Calendar integration - RSVP to meeting invitations directly from emails
• Link & attachment management - Quick access to URLs and file downloads

🎨 Professional UI/UX

• Adaptive layout that responds to terminal size changes
• Custom themes with runtime switching (Dracula, Slate Blue, Gmail Dark/Light)
• 100% keyboard navigation with fully customizable shortcuts
• Command system with auto-completion and command parity

🚀 Quick Start

Installation

Download pre-built binaries (recommended):

# Linux
curl -fL https://github.com/ajramos/giztui/releases/latest/download/giztui-linux-amd64.tar.gz | tar -xz
sudo install -m 0755 giztui-linux-amd64 /usr/local/bin/giztui

# macOS
curl -fL https://github.com/ajramos/giztui/releases/latest/download/giztui-darwin-amd64.tar.gz | tar -xz
sudo install -m 0755 giztui-darwin-amd64 /usr/local/bin/giztui

# Windows: Download giztui-windows-amd64.zip from releases page

Or install with Go:

go install github.com/ajramos/giztui/cmd/giztui@latest

Desktop app (GUI)

There's also a desktop client (Wails) that shares the same service layer and aims for keyboard-first parity with the TUI.

macOS — Homebrew cask:

brew tap ajramos/giztui
# Third-party taps must be trusted once before installing their casks:
brew trust ajramos/giztui
brew install --cask giztui-desktop

The first brew install from a third-party tap will refuse to load the cask with "Refusing to load cask … from untrusted tap" until you run brew trust ajramos/giztui (or brew trust --cask ajramos/giztui/giztui-desktop). This is normal Homebrew behavior for taps outside homebrew/core.

All platforms — direct download (from the latest release):

• macOS: GizTUI-Desktop-<ver>-universal.dmg
• Windows: GizTUI-Desktop-<ver>-windows-amd64-installer.exe or ...-windows-amd64-portable.zip
• Linux: GizTUI-Desktop-<ver>-linux-amd64.AppImage or ...-linux-amd64.tar.gz

The desktop builds are currently unsigned. macOS Gatekeeper / Windows SmartScreen will warn on first launch. On macOS 12 or newer, use right-click then Open and confirm the prompt; Homebrew installation does not remove the unsigned-app Gatekeeper warning. See docs/DESKTOP_DISTRIBUTION.md for details and the signing/notarization plan. The desktop app reuses the same ~/.config/giztui/ credentials and token as the TUI.

First Run

1. Setup Gmail API credentials (detailed guide):

   • Enable Gmail API in Google Cloud Console (required first step)
   • Create OAuth2 desktop credentials
   • Save as ~/.config/giztui/credentials.json

2. Run interactive setup:

   giztui --setup

3. Launch GizTUI:

   giztui

Enable AI Features (Optional)

Local AI with Ollama:

# Install Ollama
curl -fsSL https://ollama.ai/install.sh | sh

# Pull a model
ollama pull llama2

# Configure GizTUI
echo '{
  "llm": {
    "provider": "ollama",
    "ollama": {
      "model": "llama2"
    }
  }
}' > ~/.config/giztui/config.json

Theme Configuration

GizTUI includes several built-in themes and supports custom themes:

Built-in themes: slate-blue (default), gmail-dark, gmail-light, dracula, custom-example

Configure theme:

{
  "theme": {
    "current": "gmail-dark",
    "custom_dir": "/path/to/your/custom/themes"
  }
}

Theme directory resolution (priority order):

1. custom_dir - Your custom themes directory (if specified)
2. ~/.config/giztui/themes/ - User themes directory
3. Built-in themes (embedded in binary)

Runtime theme switching: Press H to open theme picker with live preview.

⚠️ Important for go install users: If themes don't work, ensure your config has the correct theme.current parameter (not ui.theme). See the Configuration Guide for details.

🖥️ Desktop Client (beta)

Prefer a windowed app? GizTUI also ships a Wails desktop client (a native window with a React UI) that reuses the exact same Go service layer, so behavior and configuration match the terminal. It's keyboard-first and aims for full feature parity: triage, bulk actions, move-to-folder, labels, drafts, threading, AI (summaries, prompts, inbox action plan with recategorize), saved searches, calendar RSVP, themes, and multi-account switching.

It reuses your existing ~/.config/giztui/ config and OAuth token — no extra setup if the TUI already works. On a fresh machine, first launch opens Google sign-in in your system browser.

# from the repo root
make -C desktop deps         # install the pinned Wails CLI
make -C desktop dev          # live-reload dev
make -C desktop build        # native app -> desktop/build/bin/

See the Desktop README for features and build details and the Desktop Architecture Guide for how it's wired.
