Jan vs Ollama
Short answer
Jan: Offline desktop ChatGPT alternative that runs models on each employee's computer. Ollama: The simplest way to download and run open-weight LLMs locally behind an API. They sit in different categories (Private ChatGPT-style chat and Local model runtimes) but overlap: All of them download and run open-weight models on your own hardware.
Choose Jan if you want: no server to rent (desktop app).
Choose Ollama if you want: larger community (184k vs 45.0k GitHub stars).
Ollama publishes no official RAM figure, so we cannot compare hosting cost directly.
