Claude.ai artifacts can call the Anthropic API and have persistent storage (5MB via window.storage). I used these two capabilities to build a memory system modeled on how human memory actually works — salience scoring, forgetting curves, and sleep consolidation — all running inside a single React artifact with no external dependencies.Just add artifact to your chat and paste instructions into your personal preferences setting.

Could you build this?
Yes The project is literally implemented as a single self-contained React artifact designed to run directly inside Claude using browser storage and API endpoints.
Discussion
2 comments analyzed.
Competitors mentioned: append-only logs for LLM memory, vector stores for memory storage
Concerns raised: memory bloat at scale, decay rate and consolidation frequency not yet optimized, balance between forgetting and retention not perfectly tuned
Feature requests: adaptive decay rate based on user interaction patterns, adaptive consolidation frequency based on user behavior
