About Cog
Cog is an experimental cognitive architecture layer for AI agents that adds persistent memory across sessions using structured plain-text files. It provides a shared memory with L0 headers for progressive context loading, three tiers of memory (hot, warm, glacier), and a single source of truth with wiki-link cross-references, eliminating the need for servers or databases.
Why We Scored It 4/10
4/10
Cog is a niche, open-source tool with no significant market news or adoption in 2025-2026, indicating limited impact and relevance. Its lack of reviews, traffic, and API availability further contribute to a lower score.
