Ollama

What it does

Ollama downloads, manages, and runs open AI models (chat, code, vision) locally. You type one command, it handles the rest — no cloud account, no per-request bill.

Why it matters

It turned “running your own AI” from a weekend of setup into a five-minute task. For anyone learning AI, it is the difference between reading about models and actually using them — privately and for free.

Who it’s for

Students experimenting with AI, professionals handling confidential documents, developers prototyping AI features without an API budget.

What you can build with it

• A private chat assistant that never sends data outside your laptop
• A document Q&A tool over your own files
• A coding helper wired into your editor
