Slowave

A living local memory layer across your AI tools.

Install once. Your AI tools share a persistent local memory across sessions and clients.

Slowave continuously adapts to your work — capturing decisions, preferences, and context over time.

  • Latent-space evolving memory, not yet another LLM summarizer or static vector store.
  • Lifelong learning through consolidation and decay.
  • No LLM API key required. €0 token cost.
  • 100% local. No data leaves your machine.

How it feels

Demo

You work daily with your AI tools:

  • Day 1 — cold start: Slowave bootstraps memory from existing markdown knowledge, initializing the embedding-based memory state.
  • Week 1 — emerging patterns: new interactions begin reinforcing relevant signals, forming stable associations.
  • Month 1 — context consolidates: frequently reinforced information becomes consistently retrievable, low-signal data fades.

Multiple AI clients continuously build and reuse the same evolving memory over time:

  • no markdown management
  • no static RAG
  • no LLM extra calls

What you gain over time

Slowave becomes more useful the more you use it.

  • Less repetition — you stop re-explaining the same context across sessions
  • Faster continuity — returning to a project feels like resuming, not restarting
  • Cross-tool consistency — your working context follows you across AI clients
  • Persistent working memory — decisions, patterns, and preferences are retained beyond individual chats
  • Lower cognitive overhead — no need to maintain external memory files or prompt scaffolding

Slowave does not just store information — it compounds it into usable context.

The result is a continuous working context that follows you across tools and time.

Why Slowave is different

Slowave is a brain-inspired architecture.

Principle

The human brain does not need language to remember: experiences are encoded, replayed during sleep, abstracted into patterns, and strengthened or forgotten.

Language acts as the interface, not the storage medium.

Slowave mirrors this separation: the language model is a client of memory, not the memory system itself. Memory activity — consolidation, ranking, decay, retrieval — operates over embeddings rather than rewritten text.

Biological mapping

Neuroscience describes human memory as two complementary learning systems:

  • the hippocampus learns fast — it captures individual experiences in one shot, keeping them distinct;
  • the neocortex learns slowly — it extracts the statistical regularities across many experiences into stable, general knowledge.

Neither system alone is enough. Fast learning without abstraction produces a pile of anecdotes; slow learning without an episodic buffer forgets everything that happened only once.

Slowave mirrors this division:

Human brain Slowave What it does
Hippocampus Episodic layer Captures individual experiences as they happen
Slow-wave sleep Offline consolidation Replays and groups episodes into prototypes, building a graph of associations — without the LLM
Neocortex Schema layer Holds stable, abstracted knowledge as typed claims: decisions, preferences, constraints, conventions

Three additional mechanisms emerge from this architecture:

  • Spreading activation. Recall propagates across the prototype association graph — a partial cue can recover a whole memory, the way a fragment of a song brings back the entire experience.
  • Hebbian reinforcement. Memories that prove useful strengthen and become easier to retrieve; unused memories gradually fade. Forgetting is a feature that keeps the signal-to-noise ratio high.
  • Reconsolidation. Recalling a memory reopens it. Feedback after retrieval — useful, stale, wrong — modifies the memory itself. Memory is a living state, not an append-only log.

Design rationale

Architecture

Installation

Global setup

Install Slowave and configure every detected client in one go:

pipx install slowave

# or

brew tap mrsalty/slowave https://github.com/mrsalty/slowave
brew install slowave

Then wire everything up:

slowave setup --dry-run   # preview what will change
slowave setup             # apply: MCP configs, lifecycle instructions, hooks, services
slowave doctor            # verify: daemon health, client detection

slowave setup is idempotent and safe to run multiple times. The HTTP MCP daemon and background consolidation worker start automatically as system services.

Claude Desktop and Cursor require one manual paste after setup because their instruction surfaces cannot be modified programmatically. slowave setup prints the exact text and path.

Per-client setup

To configure a single client, or to find client-specific details:

Cursor ¹ integrations/cursor/README.md
OpenCode integrations/opencode/README.md
Windsurf integrations/windsurf/README.md
Codex integrations/codex/README.md

See the complete install & setup reference: docs/install.md

Storage

The default embedding model downloads from Hugging Face on first use (~45 MB, cached locally). Subsequent runs work offline.

Memory is stored in a local SQLite database at ~/.slowave/slowave.db — fully inspectable, never leaves your machine. Not encrypted by default; protect sensitive data with OS permissions or full-disk encryption.

Dashboard

Monitor Slowave’s health, incoming events, and memory consolidation in real time.

Benchmarks

All runs: zero LLM calls, fully local, no API key. Two scorers reported: keyword-overlap (free, always computed — measures whether the right tokens appear in retrieved context) and LLM-judge (semantic grading via deepseek-v4-flash — comparable to Mem0/Zep's published numbers when they use the same judge model). Results have not yet been independently reproduced.

Benchmark n Keyword LLM-Judge What it tests
DMR 500 99.0% — Wikipedia-page factual recall
LongMemEval 500 87.8% 55.8% Multi-session facts, updates, preferences, temporal reasoning
LoCoMo 1,986 85.75% 69.29% Cross-session conversational recall across 10 real dialogues
StaleMemory 1,200 97% — Detecting when a stored preference silently changes

Full methodology and per-category breakdowns: docs/benchmarks.md.

Honest limits

  • It recalls stored information; it does not infer missing preferences.
  • It retrieves relevant memories; it does not perform reasoning.
  • Contradiction handling is heuristic and may not always resolve conflicts correctly.
  • Memory quality depends on the quality and consistency of prior interactions.

See: docs/limitations.md

What it is not

Slowave is not:

  • an agent framework
  • a reasoning system
  • a prompt manager
  • a markdown-based memory store
  • a vector database wrapper

The AI client remains responsible for planning, reasoning, and execution.

Slowave provides relevant, persistent, evolving context injection based on prior interactions.
