I Built a Private LLM Chat Environment on Colab with Ollama and Cloudflare Tunnel.
LLM services like ChatGPT and Claude are incredibly convenient, but there are moments when you hesitate to type in confidential business information or personal content. At the same time, new local LLM models keep appearing and there's a natural urge to try them out casually. Yet spinning up Ollama on a local GPU is a high bar — the setup effort and hardware cost are both real obstacles.
