March 2026
ZenBrain
12 algorithms, 7 memory layers, Sleep Consolidation, FSRS
Mem0
Simple key-value store with embedding search
ZenBrain9.0 / 10
ZenBrain is built on neuroscience research and implements 12 algorithms across 7 memory layers — including Sleep Consolidation, Hebbian Learning, and FSRS Spaced Repetition. Mem0 offers a simple but effective key-value memory store with embedding search. For complex memory requirements, ZenBrain is the significantly more capable choice.
