Memorist

Memorist is an auditable, local-first memory engine designed specifically for Open WebUI. Long-running LLM work often suffers from a loss of continuity, where critical decisions, corrections, and constraints evaporate between sessions. While most standard fixes rely on summarizing old chats into a hidden prompt—which can be invisible, unauditable, and susceptible to prompt poisoning—Memorist introduces a radically different philosophy.

With Memorist, raw messages are treated as evidence rather than mere memory. Every single message is preserved entirely unchanged inside a local ledger. By utilizing deterministic sentence segmentation, the engine produces units equipped with exact character offsets. This ensures that every memory claim can be directly and reliably traced back to the precise words that originally generated it.
