Most AI extensions lock you to one cloud model and send your text to their servers. ColibotAI is different. Select any text and translate, summarize or explain it - and YOU pick the engine: on-device with Chrome's built-in AI (free; nothing leaves your computer), your own key (Claude, GPT, Gemini, OpenRouter), or your own local model (Ollama, LM Studio). No account, no analytics, no tracking, no backend. Results save as searchable local notes. Free, Made in Switzerland.
