Bitemporal Python Packages

memware

Memory for AI agents that only remembers the latest truth: a bi-temporal belief ledger + transcript index in one SQLite file.

memvara

Bitemporal memory for AI agents: deterministic contradiction resolution, provenance, and retrieval at any point in time.

polars-hist-db

(jetstream | file) --> polars dataframe <--> bitemporal db

tgms

Agent-native bi-temporal graph store: verified temporal operators as LLM tools + trace-grounded answer verification

plugmem

Embedded bitemporal memory engine with hybrid retrieval for local-first applications and AI agents — in-process, no server.

attestari

Auditable memory for AI agents — provable deletion (crypto-shred + signed certificate), a tamper-evident audit chain, and bi-temporal time-travel recall. Runs on SQLite or Postgres.

anatid

Local memory for AI agents, with evidence, corrections and history. One DuckDB file.

vercy

Check agent memory against the Vercy Governance Overlay, plus a read-only MCP server over the Vercy model catalogue.

ontolith

Governed knowledge bases that humans and AI agents write together: append-only, bitemporal, conflict-aware.

verimem

Verified memory for AI agents: gated writes, provenance on every read, bi-temporal history, abstention instead of hallucination. AGPL/commercial.

positorium

An embedded evidence database for facts that disagree—preserving source, time, certainty, and history.

gethaki

Reliable long-term memory for AI agents — bitemporal fact ledger, contradiction detection, and full explainability. Self-host or use the cloud.

zeit-graph

Bi-Temporal Knowledge Graph Library

ragbrain

Memory for AI agents that keeps track of how facts change. Ask what is true now, what was true on any past date, or what your system believed before a correction arrived. Version history for facts, with citations.

tensordb

novodb

Bitemporal ledger database with MVCC, SQL engine, LSM storage, and PostgreSQL wire protocol. Rust-native, embeddable, with Python and Node.js bindings.

spectradb-engine

Bitemporal ledger database with MVCC, SQL engine, LSM storage, and PostgreSQL wire protocol. Rust-native, embeddable, with Python and Node.js bindings.
