Lunabot - AI assistant that works on any webpage as a sidebar chatbot everywhere

What is Lunabot

Imagine you're working on a research project and need to quickly summarize an article, translate a foreign language passage, or generate creative content for your social media—all without switching between different apps or logging into multiple accounts. This is exactly the friction Lunabot was built to eliminate.

Lunabot is a cross-platform AI assistant that works wherever you do. Whether you're browsing the web, working on your desktop, or on the go with your phone, Lunabot brings the power of 100+ AI models directly to your workflow—no API keys or ChatGPT accounts required.

The core challenge Lunabot solves is fragmentation. Most AI tools force you to choose: use a web interface and stay glued to a browser tab, pay for API access and manage technical integrations, or accept limited functionality on mobile. Lunabot takes a different approach by offering six ways to access AI: browser extensions for Chrome, Edge, and Firefox, native desktop apps for macOS and Windows, mobile apps for iOS and Android, a Telegram Bot, Siri Shortcut integration, and a web app. All of these sync in real-time, so your conversation history and preferences follow you across devices.

Behind the scenes, Lunabot aggregates all major AI providers—GPT-4o, Gemini, Claude, Mistral, Ollama, and many others—into a unified interface. You can pick the best model for each task without juggling multiple subscriptions. The platform supports context windows up to 2,000,000 tokens, meaning you can drop in entire documents and have meaningful conversations about them. Response speeds reach 180 tokens per second, ensuring the experience feels snappy and responsive.

Lunabot is built by LESSLAB LLC and serves users globally in 12 languages, including English, Simplified and Traditional Chinese, Japanese, Korean, French, German, Spanish, Italian, Arabic, Portuguese, and Russian. With multi-data center deployment and 24/7 service availability, you can rely on Lunabot when you need it most.

Core Features That Make a Difference

Lunabot isn't just another chatbot—it's a complete AI workstation designed around how you actually work. Here's what you can do with it.

Unified AI Chat Across All Models. You get a single chat interface that connects to over 100 models organized into three capability tiers. Level 1 covers everyday models like GPT-4.1 Mini and Gemini Flash for quick tasks. Level 2 brings in GPT-4.1, Claude, and Gemini 2.0 for more complex reasoning. Level 3 unlocks premium models like GPT-5, Claude 4 Opus, and Mistral Large for your most demanding work. Whether you're drafting code, writing marketing copy, or analyzing data, you can switch models with a single click.

Browser Extension for Instant Assistance. Install the Chrome, Edge, or Firefox extension, and Lunabot appears as a sidebar on any webpage. Reading a lengthy article? One click gives you a summary. Need to translate foreign text? Select and translate in place. Writing an email? Get AI assistance without leaving your inbox. The extension installs in seconds and works immediately—no configuration needed.

Desktop Assistant That Works Globally. The macOS and Windows apps run in the background, accessible via a global hotkey ( Cmd+K on Mac, Ctrl+K on Windows). You're two keystrokes away from AI assistance no matter what application you're using. This is particularly valuable for developers, writers, and anyone who switches between many apps throughout the day.

Mobile Apps With Voice Power. The iOS and Android apps let you take AI on the road. Integration with Siri Shortcut means you can trigger Lunabot with your voice—"Hey Siri, ask Lunabot to draft a meeting summary"—even when the app isn't open. This transforms your phone into a hands-free AI companion for commute time, grocery runs, or anytime your hands are occupied.

Telegram Bot for Messaging Convenience. If you already live in Telegram, the Lunabot Bot brings AI directly to your chats. Send a message, get an AI response. It's particularly useful for quick queries, translations, and brainstorming without opening a separate app.

Custom Commands for Repetitive Tasks. Create your own shortcuts for tasks you do repeatedly. Set up a command like "/blog-outline" to automatically generate blog post structures, or "/code-review" to run your code through a standard review checklist. These custom commands become your personal library of AI-powered workflows.

Who Is Lunabot For

Lunabot serves a wide range of users—from solo creators to enterprise teams. Here's how different people use it, and which features matter most for each scenario.

Content Creators. If you regularly produce content for Twitter, LinkedIn, or blogs, you know the pain of constantly switching contexts to generate ideas, rewrite drafts, or create variations. Lunabot's browser extension and web app keep you in flow. Content creator Justin told us the convenience of generating posts directly within his workflow is "much appreciated." For creators who need image generation (for social graphics, blog thumbnails, or ad creatives), we recommend the Premium plan to access unlimited DALL-E 3 and FLUX.1-dev generation.

Cross-Device Power Users. You might start a conversation on your desktop, continue on your phone during your commute, and finish up on your laptop at home. That's the whole point of Lunabot. User Matt uses it "anytime, anywhere"—logging into the web app on any device, jumping into Telegram for quick questions, or asking Siri on his phone while walking. The key benefit: your conversation history syncs instantly, so you never lose context when switching devices.

Multi-Task Professionals. If your work involves juggling multiple projects simultaneously—like a product manager coordinating with engineering, design, and marketing—context switching is your biggest enemy. User Emily describes the experience as working "seamlessly on any device," picking up exactly where she left off regardless of which screen she opens.

Developers and Technical Users. Need AI capabilities embedded in your own applications? Lunabot provides API access and a desktop assistant that developers can invoke programmatically. Developer David calls the integration "incredibly powerful"—useful for code generation, debugging, documentation assistance, and automating code review workflows.

Mobile-First and Hands-Free Users. For many professionals, the best time to use AI isn't when sitting at a desk. User Sophia uses voice commands to "complete many tasks using voice commands" while driving, cooking, or exercising. The Siri Shortcut integration makes this possible—your phone becomes a voice-activated AI assistant that works completely hands-free.

Enterprise and Security-Conscious Teams. Business users often hesitate to adopt consumer AI tools due to data privacy concerns. Lunabot addresses this with advanced encryption, a dedicated privacy control panel where you can manage what data is stored, and full GDPR compliance. Enterprise teams requiring custom deployments, SSO, or dedicated support can contact hi@lunabot.ai for tailored solutions.

Pricing Plans

We believe AI access should be simple and affordable. Lunabot offers four transparent pricing tiers, with the option to pay monthly or annually (annual plans come with an 18% discount). Every plan includes access to all platforms—no separate purchases needed.

Understanding the model tiers: Level 1 includes cost-effective models like GPT-4.1 Mini and Gemini Flash—perfect for simple queries and translations. Level 2 brings GPT-4.1, Claude 3.5, and Gemini 2.0 for complex reasoning and detailed writing. Level 3 unlocks the most capable models: GPT-5, Claude 4 Opus, Mistral Large, and FLUX.1-dev for image generation.

The Free plan gives you a taste of everything—20 daily Level 1 queries. Essential removes the daily caps on most tasks while keeping premium features accessible. Premium is the sweet spot for content creators who need unlimited image generation. Super is designed for heavy users and teams who want zero restrictions across all models.
