What it does

Jan lets you run a ChatGPT‑style large‑language‑model locally on your own computer, so you can generate text without any internet or API calls.

When to use it
  • •You need AI‑generated copy, ideas, or code but can’t rely on external APIs for privacy or cost reasons.
  • •Your team is working in a low‑bandwidth environment (e.g., on a ship, in a bunker) and still wants LLM assistance.
  • •You want to prototype or demo an AI feature quickly without waiting for a paid cloud quota.
Ready-to-paste prompt
Write a 150‑word product description for a new AI‑powered project‑management tool aimed at remote teams.
Heads up: Jan requires a recent Node.js version (≥ 18) *and* a compatible CPU/GPU; if you run the default LLaMA‑7B GGML model you need at least 8 GB of RAM, otherwise the process will crash with an out‑of‑memory error.
