Vesper transforms the Flipper Zero into an AI-powered command center, enabling users to interact with their hardware hacking tool via natural language. It targets security researchers, red teamers, and hardware enthusiasts by abstracting away complex menu navigation and protocol memorization, offering an intuitive, voice-controlled interface for advanced Flipper Zero functionalities.

How It Works

Vesper integrates the Flipper Zero with large language models (LLMs) via OpenRouter, communicating over Bluetooth. Users issue commands in plain English through voice or text on an Android device or smart glasses. The AI interprets these commands, orchestrates actions across Flipper subsystems (SubGHz, IR, NFC, BadUSB), and provides feedback. Its multimodal input capabilities, including photo analysis and smart glasses integration, offer a novel, hands-free interaction paradigm, while a safety-first architecture classifies and confirms potentially destructive operations.

Quick Start & Requirements

• Primary install: Build an APK from source (git clone, cd V3SP3R, ./gradlew assembleDebug or via Android Studio).
• Prerequisites: Flipper Zero, Android 8.0+ with Bluetooth, OpenRouter account and API key. JDK 17+ and Android SDK are required for command-line builds.
• Links: OpenRouter: https://openrouter.ai/.
• Setup: Involves cloning the repository, building the Android application, and configuring the OpenRouter API key within the app's settings.

Highlighted Details

• AI-Driven Flipper Control: Interact via voice or text for tasks like file management, signal analysis, and script generation.
• Multimodal Input: Supports voice commands, photo analysis (using phone camera or smart glasses), and text chat.
• Signal Alchemy: Features a visual waveform editor for constructing and exporting custom RF signals.
• Payload Lab: AI-powered generation and validation of BadUSB scripts, SubGHz signals, IR remotes, and NFC tags.
• Risk & Permissions Engine: Classifies AI actions by risk level (Low, Medium, High) with configurable confirmation steps for enhanced safety.
• Smart Glasses Integration: Enables hands-free, heads-up control via a bridge server for compatible smart glasses (e.g., Mentra).

Maintenance & Community

The project provides CONTRIBUTING.md and SECURITY.md files, indicating established channels for contributions and responsible vulnerability disclosure. Specific community links (e.g., Discord, Slack) or details on core maintainers are not detailed in the README.

Licensing & Compatibility

• License: GPL-3.0.
• Compatibility: The GPL-3.0 license is a strong copyleft license. Its use in closed-source commercial products may require careful legal review due to obligations to share source code of derivative works.

Limitations & Caveats

The project is currently Android-only. Interactions with AI models may occasionally result in malformed JSON, necessitating retries or switching to different models. Certain Flipper Zero file paths are protected by default and require explicit user configuration to unlock for modification or deletion. Access to AI models requires an account and payment on the third-party OpenRouter service.
