v1.0.0
0678e66

The first public release of DejaDB — the embedded memory engine for AI agents. Memory that doesn't rot: immutable, content-addressed grains in a per-file Turso database, queried with CAL (the Context Assembly Language), rendered to model-ready context in-process. Recall in microseconds — fast enough to run inside a real-time voice agent's turn.

Install

cargo install dejadb            # the `deja` CLI

Rust crates are on crates.io. Python (PyPI) and Node (npm) bindings publish from this release.

Highlights

  • Doesn't rot, measured — byte-identical re-writes collapse to one grain; updates are supersessions (1 current value, 0 stale, full history kept); 100% provenance. No LLM in the loop.
  • CAL, with no bulk delete — DELETE/DROP aren't tokens; the one destructive statement is a gated single-grain FORGET.
  • Model-native — built-in MCP server: one line gives any MCP client persistent memory.
  • Hybrid recall — structural + BM25 + vector, RRF-fused; multilingual.
  • Yours — AES-256-GCM encryption at rest (Argon2id), git-style op-log sync, forks with explicit merges, crypto-erasure.
  • A format you keep — the .mg format is documented and OMS-conformant, and deja migrate imports from mem0, Zep/Graphiti, Letta, LangMem, Basic Memory, or generic JSONL.
