Choose Spider Cloud if you need high-performance, real-time web data extraction for AI agents or RAG pipelines, with a 99.9% success rate and low per-page cost. Choose YourMemory if you want a biologically-inspired persistent memory layer that runs locally, reduces token waste by 84%, and gives your agents long-term recall without sending data externally. They solve different problems: one feeds agents data from the web, the other helps agents remember past conversations.
Local-first persistent memory for AI agents with a forgetting curve, open source and MCP-compatible.

Does Spider Cloud support JavaScript-heavy sites?
Yes, Spider Cloud includes Browser Cloud with stealth anti-detection and browser AI commands (Act, Extract, Observe) via WebSocket, capable of handling dynamic content.
How does YourMemory integrate with existing AI chat apps?
YourMemory injects a simple audit prompt at the end of a session; no API key is needed. It works with Claude, ChatGPT, Gemini, Cursor, and Copilot via MCP.
What is the token waste reduction claim for YourMemory?
YourMemory claims 84% token waste reduction over 30 sessions by pruning irrelevant memories using the forgetting curve, compared to naive context caching.
