How to clean AI memory from my PC?
Learn how to free up space by deleting massive caches from Gemini, Claude, and ChatGPT that are saturating your hard drive.
If you use artificial intelligence tools on your computer, it’s very likely that you’re losing gigabytes of space without even realizing it. Apps and CLIs from Gemini, Claude, and ChatGPT store heavy contexts, embeddings, and multimedia files that rarely clean themselves up.
Why does AI take up so much space?
Unlike traditional programs, AI models generate:
- Context Caches: Every long conversation saves a copy of the data to be faster.
- Local Embeddings: If you use RAG (Retrieval Augmented Generation), your PC saves vectors that can occupy gigabytes.
- Multimedia Files: Specifically with Gemini, screenshots and videos from multimodal contexts often accumulate.
How to clean it manually
- Claude CLI/Desktop: Look in
~/Library/Application Support/Claude/contexts. - Gemini: Check your browser’s cache folder or the CLI at
~/.cache/gemini. - ChatGPT: One of the most common questions we get is: “How do I clean AI memory from my PC?” We created Brain Cleaner because we noticed how tools like Gemini, Claude, and ChatGPT were saturating our hard drives with massive caches. In our tests, we’ve found that these caches don’t just take up space; they can also slow down your IDE’s response time. Our goal with Brain Cleaner is to automate this process so you can focus on building, not maintenance. With a single command, you can identify and delete all these residues:
brain-cleaner --aiThis command specifically scans the paths where these AIs hide their massive files and allows you to delete them safely, recovering space instantly.
Keep your digital “brain” clean and your system light!
