About

Lunabot is an AI assistant designed to make AI chat, reading, and writing help available on any webpage and device. Instead of registering separately on multiple AI platforms or managing API keys, users install Lunabot once and interact with AI models through a sidebar chat, custom commands, and voice input.

The service runs across browser extensions (Chrome, Edge, Firefox), mobile apps for iOS and Android, a Telegram bot, a Siri shortcut in beta, desktop apps for macOS and Windows in beta, and a web app. Lunabot states that it supports major models including GPT-4o, Gemini, Claude, Mistral, and Ollama, and that it offers features such as chat memory, document chat, custom commands, AI image generation, and voice interaction. Settings and conversation history sync across platforms. The product is developed by the team behind lunabot.ai.

Key Features

AI chat with memory: Lunabot remembers earlier requests and content within a chat, so users do not have to repeat context or re-select text.
Custom AI commands: Users can create their own context-aware commands and shortcuts to speed up recurring tasks such as translation or summarizing.
Multi-platform sync: Conversations and settings synchronize across browser extensions, mobile apps, desktop apps, and the web app.
Document chat: Users can ask questions about documents directly without downloading them first.
Voice interaction: Voice input and output are supported, with multiple voice formats and recognition models.
AI image generation: The tool can generate images from text and produce text descriptions from images.
Multiple model access: A single subscription covers models from OpenAI, Google, Anthropic, Mistral, and others, with no separate accounts or API keys required.
