CONTINUUM vs engrim

CONTINUUM: CONTINUUM provides verifiable semantic recovery for long-running AI agents, preventing work duplication and token waste during crashes. It achieves this through compact semantic checkpoints, independent environment revalidation, and a provenance-aware state tracking system.; engrim: Engrim is a universal, local-first SQLite memory engine specifically engineered for autonomous AI coding agents, designed to solve the '200,000-token context window trap'. It provides high-precision, curated episodic working memory, allowing developers to switch between various models and environments on the same codebase without losing architectural decisions or project state.

Features

CONTINUUM logoCONTINUUM
01Semantic checkpoints: Compact, versioned, inspectable state, not a transcript dump.
02Idempotent action ledger: Refuses duplicate external side effects; surfaces uncertain ones for reconciliation.
03Environment revalidation: Every checkpoint component verified against the current world before resume.
04Tamper-evident log: Hash-chained event log (36 event types) with integrity verification.
05Recovery engine: Seven recovery modes with a deterministic, sealed next-action contract.
engrim logoengrim
01Precision Working Memory: Replaces raw transcript replay with ~4,000 characters of high-precision, curated episodic memory, injected at boot with zero attention dilution.
02Cross-Model/Agent Compatibility: Provides a universal substrate for memory, allowing decisions made in one agent (e.g., Claude Code) to be visible and usable in others (e.g., Antigravity, Cursor).
03Local-First & Private Storage: Stores all memories locally in a SQLite file (~/.engrim/memory.db) with WAL mode and POSIX 0600 permissions, ensuring 100% privacy with no cloud sync or telemetry.
04Self-Healing Diagnostics: The `engrim doctor --fix` command verifies all hooks and installs portable PATH fallbacks, ensuring reliable operation across machines and OSes without silent failures.
05Hybrid Retrieval & Minder: Employs a hybrid lexical (BM25) and vector (model2vec) search for efficient and relevant memory recall in approximately 30ms.

Use Cases

CONTINUUM logoCONTINUUM
↳Resuming long-running AI agent tasks after crashes without replaying work, saving tokens and preserving decisions.
↳Wiring a coding agent (e.g., Claude Code, Gemini CLI) to capture file writes as hash-chained evidence and refuse duplicate side effects.
↳Integrating with various LLM frameworks (LangChain, LangGraph, OpenAI Agents SDK) to add robust persistence and verifiable recovery capabilities.
↳Ensuring the integrity and provenance of agent actions and state through a tamper-evident event log.
engrim logoengrim
↳Maintaining Project Context Across Agent Sessions: Developers can use Engrim to prevent LLMs from losing architectural decisions, user constraints, or project state when chat sessions are cleared or models are switched.
↳Collaborative Multi-Agent Development: Enabling multiple AI coding agents (e.g., Antigravity, Claude Code, Cursor) to work on the same codebase and share a consistent, evolving memory store.
↳Continue-As-Clear Workflow: Allows users to clear their agent's context window at any time, with Engrim automatically re-injecting the active memory pack for seamless continuation without memory loss.
↳Auditing Agent Provenance: Tracking which agent made specific architectural decisions or added facts to the project's memory, enhancing transparency in multi-agent environments.
