SparkMEM gives Claude persistent memory across every session — no cold starts, no forgotten context, no broken plugins.
Every Claude power user eventually hits the same wall. The tools that promise persistent memory break — or never worked to begin with.
The most popular memory MCP for Claude has been broken for months. An update dependency changed, the API call fails silently, and suddenly your agents start cold again with no warning.
Flat memory stores everything the same: a passing thought, a locked decision, a milestone. Nothing is weighted. Agents can't distinguish a five-second note from a three-month conviction. Context degrades.
If you run multiple Claude agents — a strategist, a writer, a researcher — they share nothing. Each wakes up knowing only what you repeat to it that session. You become the bottleneck in your own system.
Four tiers of memory — each with a distinct job. Nothing is overwritten. Everything accumulates intelligently.
If you run Claude for more than one session a week, you're losing context every time. SparkMEM fixes that permanently.
