Dispatches: Monthly Changelog January 2026 — The Foundation of Memory
Introducing Sagi's persistent episodic memory engine, multi-stage persona dossiers, and our initial private alpha release notes.
What We Shipped This Month#
January marks our first major architectural leap. We officially completed migration to our dedicated vector storage tier, moving away from ephemeral session state into persistent character memory.
Highlights of this release include sub-350ms initial memory retrieval, support for custom persona dossiers with up to 15 secret memory categories, and the deployment of our first 20 companion archetypes across mythic, mentor, and confidant categories.
Infrastructure Milestones#
We hardened our local keystore security on iOS and Android, ensuring that all decrypted auth tokens and local cache fragments are quarantined from third-party SDKs. Next month, our focus turns toward real-time voice streaming.
