overview

What is ColibotAI?

ColibotAI is an AI-powered web extension tool developed by Edoardo Guzzi that enables professionals and individuals to translate, summarize, and explain web text. It offers on-device AI processing or integration with user-provided API keys for various cloud models. Functioning as a Chrome extension, ColibotAI allows users to select any text on a webpage for immediate processing. Its primary use cases include rapid translation of foreign language content, summarization of lengthy articles into key points, and explanation of complex terms or concepts. The tool prioritizes user privacy, offering local processing via Chrome's built-in Gemini Nano, ensuring no data leaves the user's computer. Alternatively, users can integrate their own API keys for cloud-based models or point to local OpenAI-compatible servers like Ollama, LM Studio, or llama.cpp for fully local processing.

pricing

ColibotAI Pricing & Plans

ColibotAI operates on a freemium model, offering core functionalities without direct cost while providing options for enhanced capabilities through user-supplied resources. The extension itself is free to download and use.

  • Free Tier: Includes on-device AI processing using Chrome's built-in Gemini Nano. This tier allows for private translation, summarization, and explanation without incurring direct costs from ColibotAI or external AI providers.
  • BYOK (Bring Your Own Key) Model: Users can integrate their own API keys for various AI providers such as OpenAI, Anthropic, Google, and OpenRouter. Costs associated with this model are incurred directly from the respective AI provider based on their usage-based pricing structures (e.g., per token, per request).
  • Local Model Support: This option allows users to connect ColibotAI to any OpenAI-compatible server (e.g., Ollama, LM Studio, llama.cpp) running open models locally. While the models themselves are free, users are responsible for their own hardware and setup costs.

Similar Tools

ColibotAI vs Competitors

ColibotAI differentiates itself within the AI-powered Chrome extension market through its strong emphasis on user privacy, on-device processing, and flexible AI model integration. It competes with several tools offering similar text processing capabilities.

1
Native Translate↗

It is a privacy-first Chrome extension that performs on-device AI translation, offering offline support and preserving original page layout.

Unlike ColibotAI which provides summarization and explanation alongside translation, Native Translate focuses exclusively on on-device, privacy-first translation, including full-page and hover translation.

2
Clarity↗

Clarity is a Chrome extension that summarizes, rewrites, and answers questions about web content directly in the browser, ensuring no data leaves the machine.

Similar to ColibotAI's on-device AI and privacy focus, Clarity excels in summarization and answering questions, but it does not explicitly offer translation as a core feature like ColibotAI.

3
Summarize and Translate with Claude↗

This Chrome extension utilizes Anthropic's Claude AI model to generate high-quality summaries and translations of web pages, requiring a user's own Claude API key.

This tool directly competes with ColibotAI's 'your own provider key' model for summarization and translation, specifically leveraging Claude, while ColibotAI supports on-device AI or other provider keys like ChatGPT. It also uniquely summarizes YouTube video captions and content from image/PDF files.

4
AI Translate & Summarize & Chat with API↗

It provides translation, summarization, and chat functionalities by allowing users to configure their own API keys from multiple AI providers including OpenAI, Anthropic, DeepSeek, and Gemini.

This extension closely matches ColibotAI's BYOK approach for translation and summarization but offers broader model selection and explicitly integrates a chat feature for follow-up questions and real-time results.
