Pieces is an AI productivity tool for developers built around a powerful idea: giving you a persistent, on-device memory of your work so you can capture, organize and recall the code snippets, context and materials you encounter throughout your day. Developers constantly deal with fragments — useful code snippets, error messages, links, commands, conversations — scattered across editors, browsers and chats, and lose enormous time re-finding or reconstructing them. Pieces acts as an intelligent long-term memory that helps you save and instantly retrieve all of it.

The tool lets you capture snippets and context with rich metadata automatically added by AI, then find them again through smart search and AI assistance. But its more ambitious feature is the "Long-Term Memory" copilot, which can passively remember your workflow — what you were working on, what you looked at, what you did — so you can ask it questions later like "what was that solution I found yesterday?" and get answers grounded in your own past activity. This addresses the very real problem of context loss and constant re-orientation that fragments a developer's focus.

Crucially, Pieces emphasizes running AI on-device for privacy, so your code and context stay local, and it integrates across the tools developers use — editors like VS Code and JetBrains, browsers, and more — to fit naturally into existing workflows. It also offers an AI copilot you can chat with about your code and saved materials. This makes it appealing to developers who want to reduce the friction of context switching, retain hard-won knowledge, and have an AI assistant that actually knows what they've been doing. As AI copilots become standard, ones with persistent, personal memory of your work stand out. For developers who want to capture their snippets and context and never lose track of what they did, Pieces offers a thoughtful, privacy-conscious and genuinely useful AI memory.
