StealthIt is a free, open-source Cluely alternative and invisible AI desktop assistant designed for live meeting notes, technical interviews & coding, instant screen analysis, and voice transcription. Floating directly over your workspace, StealthIt gives you instant access to state-of-the-art AI models (Claude, OpenAI, Gemini, Ollama)—while remaining completely hidden from the taskbar and 100% invisible to anyone viewing your screen share or recording (Zoom, Microsoft Teams, Google Meet, Discord, OBS).

Whether you need a silent AI meeting assistant to summarize audio in real time, a live coding copilot that reads problem statements via OCR, or an invisible presentation prompter, StealthIt works seamlessly across all your apps without ever being captured on video calls.

Built with Python and PySide6/Qt, this repository also hosts the AI Models Competition, tracking how different LLM architectures build and optimize invisible desktop software.

StealthIt functions as a versatile AI Desktop Assistant across multiple professional scenarios:

• /antigravity-original: The baseline, original project developed by Antigravity and Gemini-3-pro.
• /claude-opus-5: A complete rebuild and enhancement of the app, built by Claude Opus 5 (featuring native desktop architecture, custom OpenAI-compatible endpoints, local Whisper transcription, and encrypted local key storage).

Feel free to explore each folder to see their respective READMEs and run the different versions!

• 👻 True Stealth Invisibility: Excluded from the Windows Taskbar and 100% invisible to screen recording tools and video calls (OBS, Discord, Zoom, Teams).
• 🎙️ Local Whisper Voice & Meeting Transcription: Press Ctrl+R to record system audio or microphone with local Whisper transcription for instant meeting summaries and verbal Q&A.
• 📸 Sub-Second Multimodal Vision: Press Ctrl+Enter to silently capture an in-memory screenshot and send it to the AI for instant code or document OCR.
• 🔒 Encrypted Local Security: API keys and transcripts are securely encrypted locally on your machine rather than stored in plaintext files.
• 🧠 Multi-Provider AI: Native support for Google Gemini, OpenAI, Anthropic Claude, OpenRouter/AgentRouter, or local Ollama models.
• ⌨️ Global Hotkeys: Operate the assistant from anywhere without losing focus or breaking active screen workflows.

1. Clone the Repository:

   git clone https://github.com/Thairu-dev/StealthIt.git
   cd StealthIt

2. Choose your competitor:

   cd claude-opus-5
   # OR
   cd antigravity-original

3. Install Dependencies: Ensure you have Python 3.10+ installed.

   pip install -r requirements.txt

4. Run the Application: If you are running the antigravity-original version:

   python main.py

   If you are running the claude-opus-5 version:

   python -m stealthit

Get API keys from your preferred providers:

1. Open the Settings menu by clicking the ⚙️ icon or pressing Ctrl+,.
2. Select your Active Provider from the dropdown.
3. Configure provider-specific settings:
   • Gemini: Enter your Google Gemini API Key.
   • OpenAI: Enter your OpenAI API Key, select model (GPT-4o, GPT-4 Turbo, etc.).
   • Anthropic: Enter your Anthropic API Key, select model (Claude 4, Claude 3.5, etc.).
   • Ollama: Configure your Ollama host URL (default: http://localhost:11434).

Tip: You can also quickly switch models by clicking the model chip in the main UI!

The StealthIt Models Competition is an open vibe-coding challenge! Developers and AI systems can architect, enhance, and submit their own competitor implementations to see which model designs the best stealth desktop AI utility.

The winning codebase will be crowned by the community and compiled into the official 1-click standalone Windows installer (.exe) with auto-updates!

1. True Stealth Compliance: Your version MUST remain 100% invisible on OBS, Zoom, Teams, Discord, and the Windows Taskbar.
2. Instant Vision Trigger (Ctrl+Enter): Must support in-memory screen snapping and multimodal analysis with zero temporary files left on disk.
3. Local Encryption: API keys must not be stored in plaintext configuration files.
4. Clean Folder Isolation: Place your implementation in a new root subfolder (e.g., /"your_model") with its own requirements.txt, README.md, and test instructions.

# 1. Fork and clone the repository
git clone https://github.com/Thairu-dev/StealthIt.git
cd StealthIt

# 2. Create your model's competitor directory
mkdir "your_model"
cd "your_model"

# 3. Build your implementation adhering to the Arena Rules
# 4. Push and open a Pull Request with your benchmark results!

We are hosting a live community voting hub to decide which model's architecture should power the standalone release:

• Phase 1 (Active): Models Competition benchmarking, community testing, and voting.
• Phase 2 (Upcoming): Crown the champion codebase and compile into a standalone .exe / .msi Windows installer with auto-updates.

Feel free to submit issues, bug fixes, feature requests, and new model competitor PRs!
