Fair question. Supermemory is a hosted SaaS built around embedding + ranking. YantrikDB is self-hosted and adds three things Supermemory doesn't do as first-class operations:

think() — consolidates similar memories into canonical ones (not just deduplication, actual collapse of redundant facts) Contradiction detection — when "CEO is Alice" and "CEO is Bob" both exist in memory, it flags the pair as a conflict the agent can resolve Temporal decay with configurable half-life — memories fade, so old unimportant stuff stops polluting recall Supermemory does more on the cloud side (team sharing, permissions, integrations). YantrikDB does more on the "actively manage my agent's memory" side. Different optimization points — no dig at Supermemory.

Anyone have experience with these and competitors? im curious if you saw a difference.

also any open source local or self hosted options?
